BALL JOINT FOR DAVID BROWN K260254, 19.9/22.3 CONE

The K260254 ball joint is an adaptable ball joint designed for certain David Brown tractors in the 90 and 94 series. It is selected primarily based on its dimensions and threads: cone base 19.9, cone top 22.3, M24 shank with a pitch of 150, M16 thread on the cone side, and right-hand thread. These specifications are essential for ensuring you install the correct part on your tractor.

A ball joint to be selected based on its dimensions

A ball joint provides a mechanical connection between two moving parts. On a tractor, this type of part is used when force or movement needs to be transmitted while maintaining smooth articulation. For this part number, identification should not rely solely on visual inspection: the cone dimensions and threads are the primary selection criteria.

The base cone diameter of 19.9 and the top cone diameter of 22.3 allow for a precise comparison of the conical diameter with the part currently installed. The M24 threaded rod, with a pitch of 150, completes this verification, along with an M16 thread on the cone side.

Useful specifications for part number K260254

This ball joint has the following specifications:

• cone base: 19.9
• cone top: 22.3
• shaft diameter: M24
• shank pitch: 150
• Thread direction: right-hand
• Thread on cone side: M16

The right-hand thread direction is an important consideration if you are replacing a worn ball joint on an existing assembly. It prevents confusion between this part number and a version with a reverse thread, which looks similar but is not interchangeable.

Recommended David Brown Applications

This ball joint is suitable for David Brown tractors in the following series:

• 90 Series: 1690
• 94 Series: 1394, 1494, 1594

These model designations are useful for guiding your search, but you should always verify the cone dimensions and threads of the part to be replaced, especially if the tractor has previously been fitted with aftermarket parts or modified during its service life.

Choose Carefully Before Replacement

Before confirming this part number, compare the removed ball joint with the listed dimensions and verify the thread direction. With this type of part, even a few millimeters on the cone or a difference in threading is enough to prevent proper installation. Checking the M24, 150 pitch, and M16 thread on the cone side is therefore just as important as identifying the tractor model.

What does the right-hand thread on this part mean?

The right-hand thread means that the shaft screws in the usual tightening direction. This is an important detail to avoid accidentally replacing it with a ball joint that has a reverse thread. Be sure to check the direction of the thread on the old part before confirming the replacement.

What does the M16 thread on the cone side correspond to?
