<VV> Question/ Answer

[Sethracer at aol.com]

Ulli - The Corvair was originally designed with press-fit piston pins.  
Those would be very inconvenient to remove with the rod still on the crank. 
Some  have been converted to floating pins, with a retainer of some type to 
keep the  piston pin in place. On those engines, it would be easier to remove 
just a  piston. However, you should know that with the Corvair motor, you can 
remove the  top breather/fan mount, and remove any or all of the 
piston/rod/cylinder  assemblies after the head is removed. You need not split the 
cases, except to  remove or replace the Crankshaft or Camshaft.

I do  have a question and there might be a question for me out there.

On a VW  engine I can change pistons without taking the engine case apart - 
the Vair  engine is some different and I can open the case on the lower end 
but do I  have to take the rods out to change the pistons or can I change 
them without  that work?
Thanks for your help.
