#1 Jockey wheel bearing

I am just preparing my drive belt tensioner, jockey wheel, for refitting and I am wondering whether they cause any problems at all? I detect a little play in the bearing, which looks on a preliminary glance to be non serviceable and would like To deal with this now if its likely to be a problem.

Don't fit it is my advice they are a pain. Use the dynamo or alternator to tension the belt instead.

Because the belts I bought from the usuals are rubbish they stretch in certain points which means the pulley goes back and forth and ended up nearly wearing a hole through my bottom rad hose.

The jockey pulley uses a sealed double-race ball bearing. When I was overhauling the mechanical bits on my early 4.2, back in 1991, I very carefully pried the front cover off of the pulley, repacked the bearings with lithium grease, and reinstalled the cover. I staked it with a small centre punch in several places to retain it. It gave me no trouble over the next several years, but if you can eliminate it entirely it'll be one less thing to cause a problem.

Thanks Mark as well. I will give this serious consideration, I guess most other cars do not have this contraption so it must be fine to eliminate it.

It's distant memory now, but when I was rebuilding my Jaguar 340 (same pulley) I managed to get a replacement bearing from an ordinary roller bearing supplier. I simply got the bearing number off the side of the bearing.

You might be even able to search using the number on-line.

The bearings are easy to get, when I rebuilt my car I got the number off the old bearing and contacted BSL who got me a new one.

Thats a tip to anyone restoring their cars don't go to the usuals for bearings they load them up on cost, BSL or any bearing supplier can supply bearings for all cars.

Ok thanks. How does it come out. Is it just pressed out or is there a cap that needs to come off first?
