One thou? That's so little, don't worry. Clamp it down without it.

The Gearbox master said i need
1 thou i know 1 thou is nothing really. but i thought u would still have to have a 1 thou preload ?
As there o thou when i checked with the feeler gauge.
Cheers

You get MORE preload when leaving it out. If you have 0 thou, you either have to find another bearing. or another C-retainer.

Well it's a new bearing. same size as the other old one.. the C-retainer is the same one that come out of the Gearbox...
So you reacon i should just tight it up as it is..
I just wanna get it right, as this is my first sc box build... dont wanna start spending more money on a new
C-retainer.. need to get this box on the Engine.
Cheers..

3 thou shim + wet & dry + elbow grease = 1 thou shim.

But I personally wouldn't worry about 1 thou, then again I break stuff.

There is no blody way you can make a 1thou shim from a 3one. First of all, it won't be homogenous in thickness, and it will most certainly break before you've finished.

Try a different C-retainer.

However, if it was me I'd just use NO shim. I've h ad to do this in the past, and that has worked splendidly.

Why not buy some 1 thou shim material and make a shim ..... lets face it it's not going to be hard to cut is it!!!!!

Every day is a school day ...........

How fast and how expensive ...... the same question...

make sure your measurement is correct
in the first instance.

1. what happened to the original one.
2. you may have to use the 3 thou one.
3. to much preload will crack the bearing and to little will make the bearing move about waering the casing.

always looking for them bigger bunches of bannanas

Hoggy: On number 3. 1 thou too much preload won't make a blind bit of diffrence. Reality check. The only thing that'll happen is that the retainer will possibly be put under more stress.

If you get 0 thou, you've possibly got negative preload. Time to find another C-retainer.

if you have another retainer then good idea to try that one just incase the bearing has worn it buy rubbing against it.

vegard 1 thou to much would be ok but any more could cause the bearing outer track to crackaround were the circlip sits , have i have seen this happen before.

Hmm maybe it could be warn.
Im no gearbox guru, but i dont feel comfortable having no thou in there.
As the way i look at it, there would be no preload, as its rubbing on the bearing..
Spose i better call minispares to see if they have one.. knowing my luck, it still have 0 thou lol

You mean it could be worn? The retainers don't wear. The only difference between them are manufacturers tolerances. Get some 2nd hand ones and try.If this fails, you could chuck it up in a lathe(extremely carefully) and remove a thou from the mating surface against the centre web in the box.

Called around but they dont make em anymore... hmmm any one got 1 they want to sell... guess i better put this in the wanted list...
If not, ill have to make a 1 thou up..

The shim, circlip or retainer cannot wear as there is no relative movement between them.
When you checked the clearance between the retainer and the gearcase web did you tighten the bolts more than a gentle fingertight?
If so you will have not got the correct reading and will need to check again. (it should be a minimum of .005" and a maximium of .015").
The workshop manual will then give you the correct shim thickness to assemble correctly.
The tolerance on the amount of nip is plus or minus .001".
If you had the retaining cap tighter than fingertight you would have distorted the retainer and been unable to measure the correct gap ( iI am guessing this is what has happened)
Did you replace the bearing and circlip or is it the one previously fitted? If you replaced it it may be worth measuring the circlip width of the old and comparing it to the width of the new one, although I doubt they will be different.
If they are a swap might bring things back to give you a measurable clearance.
I really dont think you have a retainer to gearcase web clearance of only .001", it's most likely a measuring error, check it again.

I was told to do it this way ? which of course pushed the bearing in more.. the bearing is new, and the clip is too.. all same size

Ive just done the bolts up as much as i can hand tight. and it says 10 thou.. which means i have to get a 11 thou. which i cant find on the net..
I would of thought you would have to tighten the bolt up get the bearing over as far as it can....
Ok. so which is the correct way ... touque up then check, or hand tight as much as u can go, then check..
So what shall i do now u know all this lol
I need to get this right, as ive been told different things...
Not saying know body knows there stuff, just conffusin me more, as i need to get this box on the engine. :)
