WHEEL BREARINGS

[jamcarr2]

Hi all

Its M O T time already that means I have had the stag 12 months already.I have been checking and replacing things as the year has gone on and I think that all is well But on inspection of the front wheel bearings I think they may need replacing .so the question is how easy is this to do I need a puller to get the inner one of the stub axel or will it just slide of I have read the R O M and it doesn’t mention a puller . Any one done this ? Any tips before I start ?

The whole assembly comes off the stub axle once the hub nut is removed so no need for a puller there. Looking at the ROM I suspect you just need to tap out the tracks once the bearings are out.

Front wheel bearings are dead easy to change, but they may just need adjusting - worth a look. Rear ones are a whole different story.

Clearly they will need adjusting if they are replaced, but it's possible the replacing part isn't needed.

When I adjust my front bearings I adjust the bearing so the nut is just tight and the hub spins by hand. I then replace the wheel and check for rock if not I leave if there's still some rock I start again until there is none but the wheel spins freely!

just done mine, what i did was check if there is any play 1st, if there is jack it up, remove the wheel, knock off the little greese hub, then remove the split pin. take the centre bit out of you wheel and put the wheel back on.
with the wheel back on you can check for play, if there is, just turn the hub nut a quarter turn. then check for play again. carry on to theres no play, take the wheel off and put in a new split pin with fresh greese.
job done, probably wrong but thats how i done mine, and its been fine.

I have adjusted the bearing but the reason i think it may need replacing is I took the outer bearing out to inspect and there seems to be a lot of play between the innerand outer parts of the bearing .ie if I hold the center of the bearing still the out side will move up and down a lot . Is this making sense ?

We need a little clarification here. The inner race (part) of the bearing fits the stub axle. The outer race is pressed into the hub. The bearing rollers link the two races. I think that the part you are calling the outer part, is in fact the cage that stops the rollers falling out. It has no part in the operation of the bearing. You need to clean the rollers and races to see that there is no pitting or scoring and regrease them with lithium grease.

yes done that and all is OK the play i am talking about is if I hold the inner race with one hand and the outer race with the other hand the outer race will move up and down leaving the inner race stationary . should there be that much play .

Sorry but I think you are still calling the bearing cage the outer race. The amount of play the cage has is not important, providing the rollers don't fall out. Once the bearing is assembled and adjusted, the cage is freely floating between the rollersand doing nothing. The bearings are tapered, they should be adjusted so that there is minimal play, not no play. The idea of adjusting with the wheel on is a good one as the increased diameter will show the play more clearly.

Hope that this helps.

Yes, and check for rock by holding the wheel at 12 and 6 o'clock, otherwise you will be seeing the play in the steering.
