Type 9 Tracsport
Hi,
Running a Type 9 gearbox in my westfield. It´s connected to a VW 1,8T (AEB).
Due to a couple of leaks I have to check and replace some seals.
I disconnected the gearbox from the engine today and found leaks between the gearbox and the bellhousing.
I think the bellhousing was bought from Tiger sportscars i Holland 10 years ago.
Now I need to know if anyone kan give me part-nr or dimensions of the seal in the bellhousing?
.
I also need to know if I can unscrew the layshaft bearing stub to replace the silicone.
THANKS!

I think that you have a leak between the bell housing and engine because you have oil leaking from the gearbox into the bellhousing. My Zetsc to type
9 has no gasket between the two. I may be wrong though!
Imagine if you had a gasket between the two the bellhousing would fill with oil and you would have a wet clutch !

The seal pictured is part of the release bearing that is fitted to your bellhousing, this seal is only used for the original gearbox that the release
bearing is sourced from (iirc looks like it's from an mtx75), it does nothing useful in the type 9 setup.
I had a leak in my Tracsport type 9 last year, it was mainly the gasket behind the front nose cover, I had fitted a cometic gasket kit when I built up
my Tracsport box, turns out the cometic nose cover gasket is slightly too thin for the application, and started to leak after a couple years of
use.
The shaft seal inside the nose cover was also leaking a bit as well, your shortened nose cover will still have this seal fitted in the side facing the
gearbox and is a potential source of your leakage. Something i haven't found is a good quality replacement seal here, between several different
rebuild kits I had, they all had a poor quality copy of the original seal.
The layshaft spindle is a full length shaft on the Tracsport box, not a stub shaft like a v6 type 9 , when I built up my Tracsport box I had to gently
heat up the casing to give enough clearance to fit the spindle through the bore in the casing (iirc 0.10mm oversized), this is by design to eliminate
any play when in use under load, but may make removal quite difficult without stripping the box completely, I've not had to do that so don't
know.
Due to this, I would have thought it very unlikely that oil would be able to pass through that bore even if there was no sealant used. The threads for
the bolts may be able to pass some oil through though if not sealed as I'm pretty sure they go right through the casing, I used threadlock on
those bolts as well as nordlock type washers.
A small amount of oil will also find its way out of the selector rail at the top, if the bellhousing gasket doesn't seal fully this can creep
into the bellhousing as well.
Steve Perks is a helpful chap, and may be able to point out other things that I may have missed, you can contact him from his website:
