COMPLETE CARDAN JOINT FOR JOHN DEERE CAM193810

Complete Cardan Joint for John Deere Tractor Drivetrain

The CAM193810 complete universal joint is a drivetrain component designed for several John Deere tractors. It is installed on the assembly connecting the drive shaft to the driven components, where a universal joint must accommodate the drivetrain’s movements. This part number can be identified by its 21-spline design and a set of precise dimensions, which are useful for comparing the part being removed prior to replacement.

The Role of This Joint in the Drivetrain

In this family of parts, the universal joint serves to transmit motion between two mechanical components that are not always perfectly aligned. On a tractor, its condition directly affects the smooth operation of the transmission and the integrity of the assembly in question.

Replacement should be considered when you notice play, significant wear on the splines, or visible deterioration of the assembly. Regular maintenance, including periodic inspection of the joint, also helps prevent premature wear.

Dimensions and Identification Markings

To confirm this part number, compare the main dimensions of your part:

• A: 71.5 mm
• B: 28 mm
• E1: 46 mm
• E3: 25 mm
• L1: 240 mm
• L2: 52 mm
• Groove: 21
• Position: 1 to 4

These reference points help distinguish this complete universal joint from other assemblies that look similar. The assembly is specified as made of heat-treated steel, with a design intended for agricultural transmission use. Comparing the dimensions remains the decisive factor before placing an order.

Listed John Deere Applications

The applications listed for this part include several John Deere tractors, including the 2140, 2141, 2251, 2351, 2541, 2650, 2650N, 2651, 2755, 2850, 2855N, 2941, and 2951. The 41, 50, 51, and 55 series designations are also associated with this part number in the available information.

If you are working on a 2755, a 2855N, a 2650N, or a 2141, verifying the dimensions and the groove remains the best way to confirm compatibility with your assembly. Two similar assemblies may look alike but have different dimensions.

What to Check Before Replacing the Part

Before ordering, be sure to check spline 21 first, then lengths L1 and L2, before comparing the other dimensions. On a universal joint, even a slight discrepancy can prevent proper installation or cause play in the drivetrain.

If your tractor is one of the listed models and the dimensions match, you have a reliable reference for replacing this complete universal joint. If you’re unsure between two versions, always start with the part currently installed and its dimensions to identify the correct part number.

FAQ — Frequently Asked Questions

What is the purpose of this complete universal joint on a John Deere tractor?

It is used to transmit motion through the drivetrain when the components do not always operate perfectly along the same axis. On a John Deere tractor, keeping it in good condition helps maintain smooth power transmission and minimizes play in the relevant assembly.

How can I identify part number CAM193810 before ordering?

The best way is to compare the removed part with its identification markings. This part number is identified by a 21-spline and the dimensions A 71.5 mm, B 28 mm, E1 46 mm, E3 25 mm, L1 240 mm, and L2 52 mm, with a position indicated from 1 to 4.

Which John Deere models are specifically listed for this part?

The listed models include 2140, 2141, 2251, 2351, 2541, 2650, 2650N, 2651, 2755, 2850, 2855N, 2941, and 2951. Before confirming, always check the splines and dimensions, as a single tractor may have multiple configurations depending on the specific drivetrain assembly.

When should you consider replacing this universal joint?

Replacement should be considered as soon as play develops, if the splines are worn, or if the assembly shows signs of deterioration. Regular inspection and proper lubrication help monitor its condition, but a damaged part must be replaced immediately.
