any way to reduce oil leakage out input shaft?

Well, all clear so far :-)

Unless someone comes up with a Series II based solution, we need to discover what the difference is between the "series 3 bellhousing and clutch set up" and the SII arrangement.

I guess we are mostly interested in the seal around the input shaft, but the thought occurs that surely this seal is in the box, not the bell housing?

This begs two questions, in what way is "series 3 bellhousing and clutch set up" the answer to oil leaking round the input shaft?

Is "series 3 bellhousing and clutch set up" a valid solution?

Just ideas, I don't have a SIII parts manual available.

Cheers.

Well, the Ser IIA setup has no seal as the linkage transitions from basically inside the tranny to outside. The Ser III has an external fork that pivots on a ball, so everything is outside the tranny, so a traditional oil seal can be used on the shaft. However I have heard that some military IIA's had some type of seal, though I have never seen how they work.

On a 2a the clutch release sleeve just passes thro a bronze bush with no seal(just the fit) and the input shaft that is inside the sleeve has a scroll (thread) that basically screws the oil back in to the box. S3 has a convential seal inside the front cover that runs on the input shaft.

Some(not many) military 2a's had a slightly different set up in that the bush that the clutch release sleeve fitted in had a thin oil seal in it to seal that way out and the clutch release sleeve had another seal in it that ran on a ground section of the input shaft.

Whats the adaptor issue as 2a and 3 are interchangable to all intents.

Surely there's an oil seal on the input shaft on both gearboxes? The clutch fork mechanism shouldn't make any difference.

No, the IIa has no seal as the tube the release bearing rides on would need seals both inside and out. Guess you have to take one apart to understand.

Adapter to adapt a 1.9l VW IDI to a IIA bellhousing. No room for a III clutch slave.

In that case the military sealed 2a bellhousing and clutch release is what you want, good luck in finding one they are a bit rare, probably on a par with 1 ton gearboxes and salisbury front axles for series.

Is there a good detailed pic or drawing of one somewhere? Maybe I could fab something up.
