Title: install cam=crank endplay disappears! Post by: alex d on August 01, 2007, 08:49:52 am I'm building a 1914 (yes the same that was supposed to be ready for EBI ;D ), I had a problem with an out of round cam gear, so I put there a new one, and now the crankshaft has 0 endplay, in fact one of the counterweights hits the bearing saddle so it can't turn (flywheel is not in), any ideas? ???
Title: Re: install cam=crank endplay disappears! Post by: Fastbrit on August 01, 2007, 08:53:23 am You can't check anything like this unless flywheel is on as it determines the end-float. It is common for a crank web to tuvh the case with no flywheel attached. Install the flywheel (you don't have to torque it all the way up) and check again.

Post by: alex d on August 01, 2007, 09:26:31 am I know I can't check crank end-play this way, but with the other cam gear the crank could move back and forth, with this one the crank is pushed all the way back and it just won't move to the front (with a reasonable force at least)
Title: Re: install cam=crank endplay disappears! Post by: Fastbrit on August 01, 2007, 09:30:14 am Sounds like you may have pinched a bearing. Check the bearings are located on their dowels correctly. Also, is the new cam gear marked -1, 0 or +1 (or +2 etc)?

Title: Re: install cam=crank endplay disappears! Post by: alex d on August 01, 2007, 11:12:10 am so I should look for a smaller gear? ???
Title: Re: install cam=crank endplay disappears! Post by: Fastbrit on August 01, 2007, 11:32:14 am I'd look for a decent quality one, for a start! If you're not using straight cut gears, then try to find an original VW one.
Title: Re: install cam=crank endplay disappears! Post by: alex d on August 01, 2007, 11:39:02 am I'm not using straight cuts, all I can find are bugpack (that was the out of round one) or Empi (this one) ones, so it seems it's time to find a stock one and modify it to use bolts right?
Title: Re: install cam=crank endplay disappears! Post by: alex d on August 01, 2007, 12:09:17 pm I've been told that lapping the gears with valve grinding compound can "free" the gears, what do you guys think? ???
