Rear wheel bearing spacers
 

Hi all,

I'm just reassembling the rear hub after changing the bearings and I don't appear to have the small spacer (I am sure I did when I did the other side). So assuming I need to now buy one, I will check for the 3rd time it is not on floor somewhere first, how do I find out what thickness spacer I will need??

There are 2 different parts.....
The BEARING SPACER and the ADJUSTABLE SPACER.

The bearing spacer CBC8207 is the larger spacer and the adjustable spacer is the thin shim (25 sizes) in sizes 2.22mm to 3.47mm.

The adjustable shim usually sticks to a bearing and sometimes gets 'tossed' with the bearing.
The bearing preload will NOT be correct and the hub bearings will quickly destroy themselves without the correct shim.

good luck.

My worry is the small spacer has been 'lost' by a previous repair before my ownership

Bob,
If you're ever sitting around thinking to yourself "you know I'd sure like to teach some folks something" :-), it would be wonderful to have a description of how a first (or second) timer should set things up to measure the "end float" for this part of the rear bearing replacement.

I don't know about anyone else, but I've tried to work the instructions in the Jaguar service manual, I'll admit I've asked this on here when I was in the middle of the job. The kind folk's answers never landed for me.

Tools: you need a run out gauge for best results right? I have one, but could not figure what goes where for this measurement.

Someone, could have been me, brought up using a caliper. Would that work in a crisis?

When to measure this, final assembly?

Positioning: what goes where? I bet this is a super easy one, I just cant picture it.

How should the hub carrier, bearing assembly, hub be positioned or orientated to measure?

Where would you put the base of the run out gauge?

Where does its stylus go? On the hub flat surface?

What are we measuring?
Yes we are talking about a runout guage, but this job is to measure float, that's vertical movement of the hub when the assembly is laid down hub facing up right? Certainly not measuring run out right?

Thanks Bob, like I said for some reason I just couldn't get this part of the job deciphered from the manual. Maybe now that I'm not in the middle of the job it'll (finally) land. Might help laguiotene too.

Thanks,

John
