[Drew Back]

Are the a7 longstroke cam gear and idler gear interchangeable with the later model A7/A10 as well as the crank gear??If not how do you identify?

Sorry my bad I should have looked a little closer ..will check parts box to see what I have..

Ok got the crank pinion and idler figured out my next stupid question is the cam pinion so far all I could find is one with the peg at 1200 and another with peg at 1300 in relation to the keyway im assuming the 1200 is the right one for the longstroke..

[trevinoz]

You assume correctly, Drew.

That's a significant welding repair to the crankcase in the idler bush area! Has it been run since that repair out of interest?

 Hey Drew  .... any chance of a close-up pic of the whole inner case, detailing the oil-pump cavity...??

  yours in question Is a A10 Plunger ?
Am just trying to settle my curiosity re the hole in;
Wet sumping (again!)

Was told the repair was done about 30 years ago and it had been run as a hillclimber til about 10 years ago..This is an A7 longstroke here is a pic of the second one im working on.

 Thanks Drew, so there's no hole for oil to escape through under the Crank bush in front of the pump .

 Might 'borrow your pic for the other thread if that's ok
