Transfer box thrust washers 521328

Hi, I’m looking for some advice. I’ve bought new thrust washers for my rebuild of the transfer box on the series 3.

on receipt of these, (£17 each!) , they were in plain packaging with R of China on, and not even britpart packaging as advertised. Probably are, as I’m sure britpart source them from China anyway…

So, I’ve trial fitted them, and found the clearance to be massive. Actually, the originals are within tolerance, just look quite worn, however these are at least 12 thou from being in tolerance. If I shim this it’ll cost as much again!!!

now, looking at the originals and these new ones, it clear they are machined differently. The original have the outer being the thicker part, but the new the inner the thicker bit. I’m right these run in the outer? That’s what I’m measuring. If they were flat, and the thickest thickness, they’d be about right.

I’ll try to add some photos, but anyone have experience of this? I’m thinking probably best to run the originals, however scabby they are… thanks

Are you saying the new parts are designed to fit with the original thrust washers ? I have not heard of such a thing.

Nothing beats genuine if you can get it, this is what I just used and they fitted straight in

Hi, no. They’re replacements, but are thinner than the originals by some way.

I think Bruce is right. Wish I’d seen them, as they’re not much more money.

I’ll send these p.o.s ones back and get a refund. Was looking at shim sheets to make some up, but can’t be messing about and for it to cost more than NOS.

Let’s see if JC lets me return them…..
