Yes, you certainly can assemble the case and then insert the distributor shaft after that's done. Tom Wilson's book on rebuilding Volkswagen engines has a procedure for laying the distributor shaft into the case half before putting the other case half on, but most people who have followed this procedure seem to end up with the distributor shaft "out of synch" by some multiple of 90 degrees. Either we're all reading his instructions wrong or there's something wrong with the instructions.

In any case, it's no big deal to put the distributor shaft in after the bottom end's buttoned up, particularly when you're doing the job with the case on your bench or in a stand. --------------------------------------------------------------------------- Tom Young tomyoung1@home.com Lafayette, CA 94549 '81 Vanagon --------------------------------------------------------------------------- ----- Original Message ----- From: "Sean Garrett" <seangar@HOTMAIL.COM> To: <vanagon@GERRY.VANAGON.COM> Sent: Tuesday, May 02, 2000 10:07 AM Subject: AGAIN:Bottom end reassembly?
