How are PTO U joints measured?
In the closed position, meaning the PTO shaft is the smallest it can be, get a measuring tape. Measure from the outside of each side yoke to get the closed length. To measure the universal joint, using a tape measure, measure the width from the outside to the outside (B).
Are there different PTO shaft sizes?
Regardless of what job you’ll be using a PTO shaft to complete, it’s important that you have the right size. There are two different speeds used most commonly with tractor PTO shafts, the 540 (type 1) and 1000 (type 3) RPM.
What size u-joint do I need?
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. With these dimensions, it will be easy to identify what series of U-joint that you have. Another way to identify a u-joint is by properly measuring the pinion yoke.
How much should a PTO shaft overlap?
First, there should be at least a one-third overlap between the shaft and the tube. If you’re using a slip sleeve, the overlap should be approximately 3 inches. If the shaft is too long, it will bottom out and create a conflict between the tractor and the shaft.
What is a 540 PTO?
A 540 PTO (power take off) is the standard size PTO shaft on farm tractors. It runs the equipment pulled by the tractor and also many types of equipment that are stationary. Some that come to mind are , hay elevators, conveyors, pumps, generators, log splitters, ect.
Whats the difference between 540 and 1000 PTO?
On many implements where they offer both, the 1000 rpm drivelines are sized smaller, yet still transmit as much power as the 540 drivelines, because they are turning faster, and have more gear reduction at the implement gearbox.
What size is a standard PTO shaft?
Tractor PTO Shafts

What size is a 1330 U joint?
Understanding U-Joints
| Series | Cross Width | Cap Diameter |
|---|---|---|
| 1310 | 3.219 (3 7/32”) | 1.062 (1 1/16”) |
| 1310BC* | 3.219 (3 7/32”) | 2 @1.062 (1 1/16”) 2 @ 1.125 (1 1/8”) |
| 1330 | 3.625 (3 5/8”) | 1.062 (1 1/16”) |
| 1330BC* | 3.625 (3 5/8”) | 2 @ 1.062 (1 1/16”) 2 @ 1.125 (1 1/8”) |
How many types of PTO are there?
There are two major types of independent PTOs; mechanical (i.e. 489 series) and hydraulic (i.e. new 210 series). A hydraulic shift PTO uses a clutch mechanism for engagement. Hydraulic shift PTOs apply to traditional (torque converter) automatic transmissions.
How do you measure a PTO shaft?
Measuring a PTO Shaft (Always follow the manufacture length recommendations) In the closed position, meaning the PTO shaft is the smallest it can be, get a measuring tape. Measure from the outside of each side yoke to get the closed length.
What is drive shaft u joint?
A drive shaft universal joint or u joint is designed to function with varying velocity, meaning that it allows for speeding up or slowing down with each revolution. Universal joints are common components in driveshaft assemblies on rear- and four-wheel drive trucks, SUVs, and off-road vehicles. These paired joints transfer power to move a vehicle.
What is a steering universal joint?
The steering shaft U-joint allows the steering shaft to spin at a different angle than the intermediate steering shaft. These U-joints may also use clevises or yokes to attach to the intermediate shaft and steering shaft. When the U-joint wears out, you may notice your steering wheel clunking or binding when you turn.
