Title: primary cover on classic engine
Post by: birdmove on January 15, 2008, 02:26:42 am
    Noticed my primary cover has a bit of a leak and was going to tighten the bolts. But it looks like its held in place by one large bolt? My RE manual actually seems to show its held in place by a bunch of bolts.

One bolt, however, don't be tempted to tighten that bolt too much, it's aluminum and will strip the threads faster than bob's you uncle.  I just let mine weep ever so slightly.

Not to worry...   you'll be in there soon enuff at your 500 mile service to check primary tension. Make sure seal is clean and mating surface is clean as well. any little debris can cause this.

I have put a layer of wheel bearing grease on the rubber gasket, It stopped the leak. I use type F atf

For what it's worth, we old 2 stroke Vespa scooter mechanics use wheel bearing greese instead of gasket sealer on every joint in the engine, including the intake.  It works very well and make disassembly very easy.  I resisted the idea at first and so was late coming to it, but now it's all I use.
