3b timing belt diamond washer or no diamond washer?

[Monkeymagic]

I have just found my car hasn't got a diamond washer fitted between the belt toothed pulley and the vibration damper. Should it have?
also I fitted a billet pulley. My god it's a tight fit on the crank nose. Is that right? Anyone else experienced this?

I'm hoping that is just for the ABY as I do not recall my mechanic saying anything about that when mine was done earlier in the year. If it is the case, it needs to go back. Will be paying attention to this thread.

AFAIK it's an ABY only thing, I've certainly never fitted one to my 3B.

There is a really skinny one fitted to all t4 5 cylinders. I never really saw the need but.
I can't find one on etka

I was just going to say the same, I have one on my A6, never found the part number as it came with the new vibration damper.

No diamond washer is fitted to the 3B engine.

I also found my billet pulley to be a very tight fit on the crank nose, I de-burred the back edge of/and centre of it with a fine file and some emery cloth and it's now a perfect fit. I'd rather have to do that than it be loose.

Sweet cheers kit. Let the rebuild/refresh continue

As per Kits post I had to chamfer the edge of the centre bore on my billet pulley to make it perfect.
Then again I am a serial part massager

Ha ha cheers alex. Oh and thanks for the reply about the bolts. Ste

I have been wondering if it was worth attempting to retro fit this to a 3B. The TDI one is a thin sliver compared to the the others.

Not sure what if any preperation would be necessary for a washer thats 0.13mm thick!

I have a spare ( think I got 2 with the damper ) and meant to fit it to my engine when I re-built it and forgot

It's definatley going on next time I have the cambelt off.

For the record the TDI one is 34mmX19mmX0.13mm. Febi 31815 for X-reference.

Yes I thought about it. But for what purpose?
