Why do you like nylon winch straps?

synthetic-winch-rope-care-maintenance-001

The synthetic materials industry has made its way to boat winches, and we’re happy they’re here! While steel rope still has its purpose for some winches, boats can often get by with its modern nylon compatriot in their winches.

Why do we like nylon winch straps?

The material is lightweight and easier to wind. Even heavy duty straps are reasonably light, like this one that has a 10,000-pound break strength and 3,300-pound working load and only weighs eight pounds! Unlike steel rope, it is less likely to get odd kinks as it is wrapped around the drum and this in turn lessens the probability of odd internal wearing.

What are the negatives of nylon winch straps?

Nylon winch straps are more prone to wear from the elements and from constant abrasion. Regularly checking the strap for fraying and tearing will prevent an accident the next time you use your winch, and will give you a nice heads up for knowing when you need to purchase a new one.

What is a socket wrench used for?
A socket wrench is most commonly a handle with a 90 degree ratchet, along with a set of cylinder shaped “sockets” of various sizes. The sockets fit onto the ratchet by way of a square nub. You can set the ratchet to either tighten or loosen, then keep the socket in place on the nut while you turn the handle.Mar 7, 2012

The multi leaf and the parabolic leaf spring technical

TRA-American-Leaf-Spring-BlackThe multi leaf spring design is based on the use of a flat trapezoid geometry, with cut leaves stacked one on top of the other. This leads to a multi leaf design with different lengths of each leaf. When a multi leaf spring deflects the leaves move relative each other. The contact between the leaves produces a friction between them, which leads to a difference in load between compression and decompression. The longest leaf has two eyes for assembling to the vehicle body. The strength of this leaf and the eyes are critical and sometimes the second leaf will have safety loops which hook around the main eye as a back up in case of failure. The centre of the spring is normally fixed to the vehicle axle with U-bolts.

leaf_manuf

The parabolic spring is designed for low internal friction and lowest possible weight and consequently has fewer leaves. The leaves are partly given a parabolic shape from the centre to the end of the leaf, which gives an equal bending stress level along the parabolic part. This ensures efficient use of material and minimum weight. The shape of the leaves are such that contact between the leaves only exists at the centre and the ends. And since the centre of the leaf spring is fixed to the axle with U-bolts, the only friction comes from the end contacts. Rubber pads are also sometimes used to lower the friction. As with multi-leaf springs, the strength of the eyes is a critical safety factor.

Leaf springs can be divided in to three broad areas:

– Preparing leaves

– Bending – heat treatment – shot peening

– Assembling – presetting – surface treatment

Trailer-Leaf-Spring_1

Leaves for multi-leaf springs are prepared by cutting and stamping whilst parabolic leaves are hot rolled in a purpose-made rolling machine. The ends of the main leaf are heated and the eyes are then hot rolled. The leaves are heated and individually bent to the correct arc radius and, whilst still clamped between the bending tool, each leaf is quenched in oil to receive high strength and the correct shape. Parabolic leaves also have an arc radius but are however normally straight in the thicker central section. The leaves are finally tempered for high material toughness and strength.

After cooling, the shot peening process is necessary for all parabolic leaves. For multi-leaf springs however, it is normally only the two safety-critical leaves that require shot peening. The bushes are pressed into the eyes and the stack of leaves is assembled. Positive stresses are then introduced in to the spring by a pre-stressing process.

The multi leaf surfaces are protected against corrosion by painting of the outer surfaces and by lubrication between each leaf. Parabolic leaves are individually painted on all surfaces.

Selecting Proper Trailer Axle Assembly

Before selecting an axle assembly for your application or local market, we suggest you consider the necessary specifications below:

 

axle

• Load Capacity: The load rating of the axle must support the maximum gross vehicle weight rating (GVWR). For multiple axle trailers, divide the GVWR by the number of axles to determine the minimum load capacity of each axle.
• Brake Drum: The area of the brake lining is the key factor that influences the brake system. Make up your mind on what you want for the diameter of the brake shoes and the width of the brake lining.
• Axle Style: People from different places may have different habitual preference for axle style. German axles and American axles may differ in beam shape (round or square), spindle size and some other specifications. Determining right specifications is especially important when reusing existing hubs or drums.
• Track Length: Measure your axle track length by determining the distance between the center of one tire to the center of the other tire.
• Spring Centers: Measure the distance from the center of one spring to the center of the other.
• Overall Length: Measure the distance from the very end of an axle’s spindle to the very end of the opposite spindle.
• PCD: This is important for axle assembling. The PCDs of the brake drum and the hub have to be the same.

What is the relay valve ?

relay valve is an air-operated valve typically used in air brake systems to remotely control the brakes at the rear of a heavy truck or semi-trailer in atractor-trailer combination. Relay valves are necessary in heavy trucks in order to speed-up rear-brake application and release, since air takes longer to travel to the rear of the vehicle than the front of the vehicle, where the front service brakes, foot-valve, parking-control valve, and trailer-supply valve (if applicable) are located.

In a truck’s air brake system, relay valves get a signal when a driver presses the treadle, which then opens the valve and allows air to enter the brake chamber via air inlet. The diaphragm gets pushed, then the rod, then the slack adjuster which twists to turn the brake camshaft. Next, it moves the disc, wedge or s-cam, which pushes the brake shoes and lining, creating friction. This friction slows and eventually stops the brake drum’s turning, which stops the wheel.

Hard to Find Leaf Springs for Classices Cars at New Truck Spring

You may have heard of the old saying, “They don’t make them like they used to anymore!”

In part, this is quite true when it comes to the automotive industry. Earlier cars were considered a luxury for only the rich, and they weren’t mass-produced on the level that they are today. Resources were plenty and the demand for such vehicles for those who could afford it was substantial, but for today’s numbers, the ownership of classic cars are still quite low.

As a result, the materials used back then were heavier, bulker, and today—expensive! What’s more, when it came to the smaller parts of the vehicle like the suspension system, inventors were still in the earlier stages of discovering what makes up a smoother ride—and in essence, still are today!

The Challenge of Finding Replacement Parts

Whether you want to refer to these earlier cars as old or classic, the truth somewhat remains that indeed, they don’t make them like they used to! So for car collectors and classic car owners who may have received their treasure through an inheritance, an auction, or the sheer luck of stumbling upon it in a junkyard, chances are you’re probably having a challenge finding replacement parts for your leaf spring.

The chances are quite slim that you’ll find leaf springs for a classic car at your local automotive store. Even if you’ve gotten by with combing junkyards for parts, when it comes to classic cars, you won’t have much luck. Even if you contacted the manufacturer, the response that you’ll most likely get is that particular model is obsolete and yes, they don’t make them anymore!

So if the manufacturer doesn’t make leaf springs for their earlier models, and finding replacement parts makes finding a needle in a haystack look easy, what exactly are your options? You could, like most ex-classic car owners, scrap the parts out and sell the material, or you can call New truck Spring, a leaf spring replacement and manufacturing company in New Century, KS.

1. Truck drivers in the usual should pay more attention to leaf spring maintenance, lubrication should be carried out regularly to prevent the lack of lubrication caused by shock absorber failure.

2. In the usual maintenance process should also pay attention to horse bolts, center bolts fastened to prevent the damage caused by the steel plate spring bolt loosening.

3. The number of leaf spring is closely related to the rated load of the vehicle. When the vehicle is often under overload or partial load, the fatigue strength of the leaf spring will be reduced and the service life of leaf spring will be reduced.

4. In order to extend the life of the leaf spring, should avoid running too fast, especially in the rugged road driving, the speed will lead to excessive acceleration of steel leaf spring fatigue and damage.

5. When driving to minimize the emergency brake, otherwise it will let the leaf spring to withstand greater bending stress and tensile stress; In addition, when turning, the speed is too fast, will increase the outer Truck leaf spring load, speed up Damage to leaf spring.

Popular Toyota Truck Leaf Springs

Popular spring replacements include Model 90-297HD the 3/1 Rear Leaf Spring for the 2005-2011 Toyota Tacoma. This replacement spring fits on the left or the right side and can be classified as a heavy duty spring as it offers 1,650 lbs of load support.

As a general rule of thumb, when you replace something as vital as suspension leaf springs in your Toyota Truck/SUV you should always look to replace the u-bolts to go along with the springs. The reasoning behind this is for additional safety and stability throughout your Toyota and without proper U-bolts the leaf springs will not sit right in on your chassis. We offer custom bent u-bolts that can be made to fit specific measurements.

How do you determine what leaf spring you have on your vehicle?

Leaf springs are commonly used in heavy duty trucks, pickups, vans and SUV’s and are a critical part of the vehicles suspension.  At some point they will reach the end of their life expectancy and will need to be replaced, but how do you determine what leaf spring you have on your vehicle?

For do-it-yourselfers, this might sound like a difficult task, but there are a couple of simple ways to identify your leaf spring.

O.E.M. Part Number

One method of identifying a leaf spring is using the O.E.M. part number.  O.E.M or stamping numbers are located on various areas of the leaf spring.

Full Taper Spring stamping numbers can most commonly be found on the end of the first leaf.  Other locations include the side, bottom or top of the clip, or at the end of the wrapper.

leaf-spring
Multileaf Springs stamping numbers can most commonly be found on the side, top or bottom of the clip.  They may also be found on the bottom of the last leaf beside the center bolt or on the end of the shortest leaf.leaf-spring-1
Trailer Leaf Spring stamping numbers are found on the outside of the hook.

leaf-spring-3

In many cases, the stamping number may contain only a part of the O.E.M. part number.  Ford usually only stamps the prefix and the suffix. The base must be added to complete the part number. For example F3HT5310JA, D7HT5560AUA or D1TA5588AA, whereas 5310 represents a front spring position, 5560 a rear position and 5588 a helper spring.

leaf-spring-4

 

Identification by Spring Dimensions

A second method of identifying a leaf spring is by the spring’s dimensions.  This is by far the most difficult method, but can be used if no stamping number is found or is unreadable.  Five measurements will need to be taken to determine your leaf spring model.

The first measurement is the Main Leaf Length.  Leaf springs come in different types and will require a particular way to measure that style of leaf spring.

For an Eye to Eye style leaf spring, measure from the center bolt to the center of the eye in both directions along the arch.

leaf-spring-5

For an Eye to Slipper style leaf spring, measure from the center bolt to the center of the eye and center bolt to the end without, along the arch.

leaf-spring-6

For a Slipper to Slipper style leaf spring, measure from the center bolt to the end in both directions along the arch.

leaf-spring-7

For a Camel Back style leaf spring, measure from the center bolt to the end of the main leaf in both directions along the arch.  This is for Mack trucks only.

leaf-spring-16
And for a Single Point style leaf spring, measure from the center bolt to the end of the main leaf in both directions along the arch.  End hole size and distance from the center bolt must be checked.

leaf-spring-15

 

The second measurement taken is the Leaf Spring Width.  This is measured at the center bolt from side to side across the leaf.

leaf-spring-14

 

The third measurement is the Pack Thickness.  This is measured at the center bolt down the side of the spring including all leaves, tow eyes, shock eyes and pads.
leaf-spring-11

 

The next measurement is the Leaf Spring Arch.  Again, depending on the leaf spring style, a particular measurement must be taken.

For an Eye to Eye leaf spring, use a straight edge to mark the center of the eyes and measure the arch at the center bolt.  Always measure to the top of the main leaf and do not include any pads or spacers.

leaf-spring-12

For an Eye to Slipper leaf spring, use a straight edge to mark the center of the eye and the top of the slipper and measure the arch at the center bolt.

leaf-spring-13

For a Slipper to Slipper style leaf spring, use a straight edge on the top of the slipper ends and measure the arch directly over the center bolt.

Leaf Springs

For Camel Back style leaf spring, use a straight edge to mark the top of the main leaf in both directions and measure the arch at the center bolt.

leaf-spring-10

And for Single Point style leaf springs, use a straight edge to mark the top of the main leaf in both directions and measure the arch at the center bolt.

leaf-spring-9

 

The final measurement is the Eye Leaf length.  This is measured from the center of the eye to the center bolt along the arch.

leaf-spring-8

Whether you use the O.E.M. part number or measurement method, you will have the necessary information needed to replace your leaf spring.  Let one of the suspension experts at NewTruckSpring.com help you with your leaf spring selection Send mail:info@tinmyautoparts.com visiting us online at NewTruckSpring.com

Look at a few common reasons why leaf springs causes of failure

Ever have a leaf spring crack, become fatigued or break and wonder what the cause is? We will take a look at a few common reasons why leaf springs fail.

Loose U-Bolts

 
The image below shows center bolt failure due to a truck spring not having tight enough u-bolts. U-bolts, especially on newly installed truck springs should be checked periodically to verify they are tight. Even if you have a professional installer install springs on your truck, you should stop by after 500 miles and have your u-bolts inspected to make sure they didn’t come loose.

leaf-spring-failure-1

Corrosion and Fatigue

Corrosion and fatigue are typically caused by a combination of time and the elements. Numerous variables will weigh on how long your leaf spring will last before it suffers from corrosion or fatigue. How much weight you haul, what part of the country you live in, etc. will play a role in the life of your springs. Making sure salt and other corrosive materials are washed off and not overloading your truck will help prevent corrosion and early spring fatigue.

leaf-spring-failure-2

Overloading Your Truck Springs

Everyone says they never do it , but we see it all the time. Overloading is pretty self-explanatory. You have more weight in the back of your truck or you are towing a load heavier than what your truck is rated at. We all love to do it, but the negative effect on your truck springs is unavoidable. On the left image below you can see the radial shear marks from an overloaded spring. The image on the right shows distortion of the spring eye from overloading

leaf-spring-failure-3

How do you prevent overloading your truck springs? Obviously you could carry less weight or purchase a truck with a higher weight rating. If buying a new truck or hauling less weight is not an option, you could add an overload kit like a Firestone Air Spring kit, Hellwig Helper springs or a Air Lift Air Spring kit. Overload kits are designed to take some of the weight off the leaf springs and place it onto the overload kit.

Another option that is more popular with commercial vehicles it to add another piece of steel to the spring pack. This may cause the ride to be stiffer, but if you are always hauling heavier loads in a commercial setting this may be your best bet.

We do not recommend adding a new piece of steel to leaf springs that already suffer from fatigue. You are better off replacing both of your truck springs with new ones with a higher weight rating. It’s very common that we will have someone only want to replace one busted leaf in a spring pack and a few months later a different leaf breaks. If one has cracked, the others are probably in the same condition and will not last much longer.

Weld Splatter

Weld splatter is more common in commercial trucks and vans that come from the factory without a bed or on motorhome leaf springs . This is caused by welding a body or accessories to your truck in the same area as your leaf springs. Just a small amount of weld spatter can be disastrous to the life of your spring. About the only way to prevent this is to inspect your springs after and make sure no one was careless with the welder.

leaf-spring-failure-4

Above are a few common reasons why leaf springs fail. There are other manufacturing reasons such as quench cracks, tight eyes, notches, incorrect temperatures, etc. that can cause failure. With today’s modern, high-tech manufacturing processes and quality control, they are not nearly as commons as they were in the past.
