Predator 38 cutter head bearing

[Al Cormack]

Anyone done the job of changing this bearing on a Predator?

Yes, it is fairly straight forward. Is the collar and shaft ok? We did an older one a little while ago and the threaded collar was knackered. The new collar is a different thread which then required a new stub shaft, different seal etc. Costs on parts was in excess of £500

Collar and stub is fine. Picked up a new bearing and oil seals today, so got to press the shaft and bearing out, and then back in again.

Pressed the old bearing out and the new one in. The oil seal in the ring is not sitting flat to the bearing housing, even though the bearing is pressed fully home.



The bearing supplied looks a little different to the original, but assuming they are the same size.

Any ideas?

Too late to use a verynear caliper (sic) on the width of both bearings I suppose?

Going to press it out again and measure, also check the housing isn’t damaged in any way stopping the bearing sitting properly.

All good. Predator say there is meant to be a slight gap as it pushes on the outer race to stop it spinning.
