Post by Workinprogress »

Thanks,
Bruce

It's not Auto - they were different again.

That's from an early 850

Early 850. I suppose if you were to change the rear bush in it you could use it on a 997. It is not correct for a 997 as is.

Just checked mine, it's a 22A 520.....

Looks like the very first Deva bush style......It's for small tail shaft, and, I believe it was part of the conversion kit to modify early small tailshaft wet primary gear/crankshafts to dry.....

No numbers on these gears, mine was written on a piece of tape that was still readable....

Your gear is 22A 79, earliest gear for small tail wet primary gear cranks.......

The gear I have would be a Service Replacement with a couple of plugs (to plug the holes in the crank), as a "Fix" for the leaky wet style gears that leaked oil all over the clutch......
