Quick Answer: What is the difference between a 1310 and 1350 U-joint?

Size and strength. The 1310 series joint is what you would expect to find stock in most Jeep or small trucks. A 1350 series joint/shaft is what you might find in many full size trucks. While it’s not 100% accurate, you could say that a 1310 is a “half ton” joint and a 1350 is a “one ton joint”.

How strong is a 1350 U-joint?

Relying on information provided by the manufacturer of the components, our calculation is that the 1350 series joint is about 37.5-percent stronger than the 1310 series. The 1350 U-joint is rated for 2,200 lb-ft (minimum elastic limit) of torque.

How much power can a 1310 U-Joint handle?

According to Spicer, the 1310 joint is rated at 400 lb-ft of continuous torque (down the track) and 800 lb-ft of short-term torque (launch at the line). The 1330 has the same size caps as the 1310, but the U-joint cross is the same size as a 1350.

Are all 1350 U-joints the same?

Standard u-joints sizes are classified by series, with each series having specific cap diameter and overall joint width. Typically speaking, a higher series number translates to a stronger joint.Understanding U-Joints.

Are all 1310 U-joints the same size?

This allows you to mate a larger (or smaller) U-joint to the other. For example, you buy a new driveshaft that comes with 1350 weld-in yokes, but your car has 1310-sized yokes for the transmission and rear differential.U-Joint Sizes.

7290 2.622 1.126″

What is the difference between 1330 and 1310 U-joint?

1330 joints use a larger body than the 1310 joint but the same-size trunnions and caps. They are often found in 3⁄4-ton trucks and allow more angularity than 1310 joints but are only marginally stronger. 1350 joints are found in 1-ton trucks and use the wider body of the 1330 joint but with larger trunnions and caps.

How are U-joints measured?

You will need to measure from the edge of one snap ring groove straight across to the edge of the other snap ring groove. For U-joints with outside snap rings, you will need to measure from the edge of one u-joint cap straight across to the edge of the other u-joint cap.

How much drive shaft angle is too much?

Ideally, both driveshaft-operating angles will be 1 to 3 degrees. Anything over 3 degrees at the rear axle will shorten your universal joint’s life and could create vibration. If your angle is larger than 3 degrees, you must make sure not to exceed max driveshaft RPM as shown on this Spicer table.

What is a 1350 u-joint?

Non-cross-drilled Heavy Duty 1350 U Joint

The Thrust washers in each bearing cap is to eliminate metal on metal contact preventing wear and lower overall operating temperature. It is non-greaseable design that is factory lubed with synthetic grease for excellent friction reduction.

What is double cardan joint?

A Double Cardan joint is essentially two single Cardan joints connected by a coupling yoke that contains a centreing mechanism. This centering mechanism keeps the input and output shafts in the same plane, regardless of the operating angle.

How do you measure a 1310 u-joint?

How to measure yokes and u joints

Does drive shaft diameter matter?

The longer and smaller (diameter) a driveshaft is, the lower its critical speed. Critical speed is felt as excessive vibration that could cause the unit to fail.

Do universal joints work at 90 degrees?

It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant-velocity joint.

Do they make u-joints with different size caps?

Yes they do sell Ujoints with different size caps on each end. I had to use one when I bought a different driveshaft for a 1984 chevy truck that I had.

What is a conversion U-joint?

Conversion U-Joint 1310 Series To 1350 Series

Normally the larger the U-Joint the stronger it is. The 1310 to 1350 U-Joint Conversion is a mix of two different series specifications on the same u-joint so that that different sized yokes and driveshafts can be connected.

How do you measure driveshaft angle?

Place a spirit level protractor on the driveshaft about halfway between the transmission and the Differential. Read and record the angle shown on the protractor scale and note whether the driveshaft points up or down at the front. Record the angle as “3 degrees up” or “2 degrees down,”etc.

What is the best driveline angle?

Most driveline companies recommend operating angles of 3° or less for maximum u-joint life. There should be a minimum of ½° to allow the needles to rotate. The higher the operating angle, the more likely your vehicle will develop a vibration at high driveshaft speeds.

What is the minimum U joint working angle?

RULE 1: UNIVERSAL JOINT OPERATING ANGLES AT EACH END OF A DRIVESHAFT SHOULD ALWAYS BE AT LEAST 1 DEGREE.
