Anybody used one?

They're about £100 and wanted to know if they were worthwhile.

Thanks

I feel your feel.

Also interested in this.

Link?

found a cheaper one here

I would also like to know as I have an valver gearbox thats in bits and a spare G40 box with mashed bearings.

If anyone gets to speak to suppliers or sellers with info, could they try and find out the manufacturer of the bearings too.? I'll see what I can do regarding this, no use buying cheese I'm thinking its gonna be worth paying a bit extra for good ones.

Just rebuilt another 085 that needed a new diff planet gear, full set of bearings and a fifth gear syncromesh.

Here are the part numbers for all bearings used in the 085:

3 x Timken xc06536cd/jxc06536dc

1 x SKF l44649/610/q

2 x SKF 330757c/qcl7cva606

Where I've quoted two numbers for the same bearing, those are equivalent part numbers.

Don't forget any new bearings should be shimmed as per the vag workshop guide for correct running clearance.

Might be worth pinning this if possible...

Thanks for the info Vic.

So where do you source your bearings?

Also, where do I find out about the shims? Can I reuse the originals? I was hoping it was a case of straight swapping the bearings and seals.

Thanks

You up for doing another one, Vic? I might be able to get you some regular work..

I just ordered them from a few suppliers, simplybearings.co.uk comes to mind. You can certainly reuse the 1mm shim fitted to one side of the diff, but you still need to assemble the box and use a dial gauge to measure clearance. The diff and intermediate shaft must have bearing preload that you calculate after measuring clearances. Shims come in different sizes and cost about £7 for a set of three from a vag dealer.

I can't see anyone wanting me to rebuild an 085, the last one cost me just over £260 to rebuild. I have to pay for bearings to be pressed on, not cheap. My labour was free on that one too! Don't get me wrong, these are horrible to work on.

@mikey, I can help you out but the last thing I need is a bucket load of broken 085's to go through. I've seen a fair few that were just not worth doing as new parts cost is horrendous.

£260 quid? Yowch! How much of that was parts?

I replaced a synchro £25 (iirc),

Bearings, all seals, shims £110

Beadblast case £25

Bearing removal/press new ones in £50

Oil £40

New clutch sleeve guide £12

The beadblasting is of course optional, but I find it easier to work on a clean casting...

Ok thanks.

So that would suggest the 085 rebuild kits don't include everything needed?

I plan on doing the crown wheel rivet overhaul and thought it may be worth changing bearings and seals while I'm at it - maybe if it isn't broke don't fix it?

Thanks

So is that a bare aluminium/alloy casing? Or is it painted too?

I think if you're going to invest in bearings then that's the time to do the second gear synchro. I wouldn't want to fit and shim bearings to find out it crunches in to gear. The crown wheel fix is a great idea, I've yet to see ruined diff bearings, mainly intermediate shaft and fifth gear bearings. If it doesn't whine or rattle then i'd leave well alone!

@leeds, the box in the pic is painted aluminium. I figured it would weather even quicker after blasting so I etched it and painted it in aluminium look paint.

The rebuild kits are very good BTW, although not strictly rebuild kits, just seals and bearings. Bare minimum you would need shims and oil plus a five ton press.

Hmmm, I'll probably just stick to my original plan of just replacing with cheap boxes until supply starts to dry up

Well I think i've only killed one bearing, one i've minced once in the past, its the one for the clutch-end of the output shaft. You can see the recess for it in the bell housing.

So until funds allow I'm tempted to just replace this with a new one. Would you have a part number for this bearing, Vic?

When funds do allow should get it reconditioned. At least I'll have a 12 month guarantee.

Yep, that's the one that dies first.

Part no: 1 x SKF l44649/610/q

Beware that you'll still need to shim the new bearing up, the shaft has 0.75mm of bearing preload.

To remove the old race you'll need a blind bearing puller or run a bead of weld around the race which will shrink it and the race will fall out.

Cheers Vic

Definitely a weak link, opposite the diff so you'd think they'd have gone for something a bit bigger.

Yeah I replaced it in a 1.6 box I was putting in the wifes ill-fated valver a couple of years back. I used a bit of heat on the aluminium from the other side, was easy but somehow I prefer your idea, will try that way this time.

I'm with 2 others at the minute rebuilding a G40 gearbox.

should we start a groupbuy on some of this stuff?

i have bearing pulling pulling tools- and a range of presses at work more than big enough to do the work if people wanted those bits doing for a fraction of the cost

I've got a g40 box to rebuild and another g40 box complete in unknown condition that I'm dropping the quaife in, so any way I can save money is good for me!

if that rebuild kit is from the same seller i bought the one for my 020 box from then the bearings are good makes SKF, Timken and the likes and very good money as i priced up the bearings seperately and it came to well over the price of the rebuild kit alone without the gaskets you get too.

Well I had a choice of budget, SKF or Timken, bit concerned some refer it to an Imp bearing, if that's Hillman Imp then i'm not surprised it fails!

Time and weather mean I won't be waiting at the door mat for it, though..

You sure? Not for this gearbox it ain't..

That's the bearing I bought, that's what it says on the box, but its 2mm too small to go over this output shaft. Stretch iiit !!

I notice the oil inlet drain for the outer race is bigger than one i've seen before, I think VW may have made a change to try and strengthen them for the 6n2 perhaps? Its a very late 6n box or was at least from one - DKF i think, checks out for the car it was from.

So now I need the part number for this one. I'll try VW but it'll have to be Monday now.

Made it to VW today, and their computer rightly specified a 29x50 bearing instead of the 27x50 bearing.

Part number for this 29mm x 50mm bearing is; 311 405 625 N

Its an FAG bearing, made in Korea but looks like jewelry compared to the SKF one - so it should at twenty five quid.
