PAS Pulley Seal Question

[maxstu]

Not the engine case pulley seal. But the one sitting behind the PAS pulley. It doesn't come with any rebuild kit, either.

I thought l had one l bought separately, but now l'm uncertain it is the correct seal? It measures slightly different from the one l removed from the crank.

Brickwerks out of stock, too.

Has anyone got a new one and willing to measure diameter and thickness for me please?

Seal thickness dimensions

parts catalogue says 36x4

it might be viton rather than nitrile for the heat

Thanks for the info. I guess that is an internal diameter at 36mm? That roughly matches pulley shaft at 37mm

The new one feels soft to the touch and l don't think is correct, especially with a 34mm ID and 42mm ED.

Trying to source one at present. But not urgent. Have set up an back in stock alert with Brickwerks.

Whats the depth of the recess it sits in?

36mm od 4mm thick

36mm od 4mm thick

Getting confused now.



More precise measurement...44mm od

I think it is the correct seal that is in my possession.
I checked out the listings posted by Tobydog and they do tend to come up slightly smaller dimensions than listed. A bit like timber.

Once over the crank end it will fit.





I will use this.

O rings are usually listed by ID and section

From your piccy, (44)-4-4=36

my bad i and o next to each other on keyboard 36 id 4mm thick

[maxstu]

Well, between the three of us we eventually got there...

I must have bought this seal from Brickwerks. So safe to assume it is good for the job.

It's just Buna-N (nitrile). Not especially hot inside an engine, actually rather cool as hot things go. That is, if you deal with hot things. But them that don't think everything's too hot.

Thanks very much. Yet, is it the correct size?
