Crown wheel thrust washer orientation?

Recommended Posts

Hi All,

I’m struggling to remove the old output shaft oil seals to allow for replacements. I have the passenger side out using a puller but the drivers side refuses to budge. To help I have removed the crown wheel preload ‘nut’ which houses the seal and will tackle it on the bench. However in my haste while the housing was out I removed the thrust washer from it and neglected to make a note of it’s orientation. The washer has a small lip on one side, should that face away from the ‘nut’ or press up against it. 

I’ll take a photo when I get home later if necessary. 

Thanks

-Chris

All I can saw is it needs to be fitted correctly - or you end up with a CWP set like the one in my scrap pile.

@Blackngolds3turbo - you’ve just done yours - any idea

Thanks Barry, I think I know the correct way round it should go but as you say it's pretty critical hence the need to double check.

It just occurred to me that I have a spare gearbox buried under a bench, I will pull that out and compare. 🙂

cheers

When you replace the "nut" make sure the threads are well coated with sealant or you'll have oil leaking past them. :thumbdown:

I checked out the spare gearbox and it was positioned as I suspected as shown below, this gave me the level of confidence I needed.

Here is the spare 'nut' with the bearing shield (not a thrust washer at all) installed.

And here you can see the orientation of the shield demonstrated with the one I took out too quickly.

Thanks for the help, hope to see some of you at the weekend.
