Just split my case, trying to pull the crankshaft from the case half but on the flywheel mounting side it does not want to budge at all from the case! The impeller side is free, but all my efforts of trying to break free the other side did not prevail. Even tried turning the case upside down, with helper holding the crank from the bottom, and me giving some good wacks with the rubber mallet to the top of the piston rod closest to the flywheel from the top, hoping gravity would help, but that still didn’t work... anyone else come across a tight crank that would separate??

Did you get the crank out ? suspect with a linebore it may have had dowel pin repair work and be a bit tight on that bearing,I don't see how a piece of valve spring could migrate down a pushrod tube....but you never know so carry on the way you are going,good luck.

Yes finally got the crank out! Attached the flywheel, turned the engine upside down on the stand, had someone holding the crank from under while I gave a really solid whack with hammer and brass drift to the top of the flywheel, boom popped out. I agree completely. Since it was lined bored and had custom over side journal bear I gave and F/R main bearings made, all done by Headflow Masters, I suspect the tolerances were very tight, and definitely were not intended to be pulled apart after only 5K mi of wear... Also agree that I thought it very unlikely for the spring piece to make its way through the pushrod tube, especially since there were no scratches on the pushrod tube... but the local VW shop Paradise Motorsports said there was a chance it could be in there and better to be safe than sorry I guess... Thank you for everyone’s input and help getting me to just whack a little harder and a little smarter (IMG:style_emoticons/default/biggrin.gif)    |
