Needle bearing (transmission) 917/02600 JCB, genuine

Needle bearing (transmission) 917/02600 is a genuine JCB part for the JCB machines.

When the bearing is changed, inspect the shaft track and the gear bore: if there are marks, wear or heat discolouration, a new bearing will soon fail and the shaft or gear should be replaced. The needle bearings of the other gears run in the same oil, so when one fails it is worth checking them all. The washers of thrust bearings are checked along with the bearing, and a washer showing marks or wear is replaced too.

Specifications

Compatibility

Fitting

On assembly, lubricate the needles and shaft with clean transmission oil, push the caged bearing onto the shaft without tilting and make sure no needles drop out as the gear goes on. Fit thrust bearings in the right order together with their washers. After assembly, check the shaft end float, fill with the specified oil and listen to the gearbox on the first run. To stop the needles falling out during assembly, the bearing can be held lightly with clean grease, which dissolves in the oil on the first run.
