/7 engine teardown surprise

[bigfella]

Hi Fellows, I'm presently stripping the engine from my R100/7 and have struck a little snag.

Original double row cam chain is in place, puller is being manufactured for the crankshaft sprocket. Problem is the camshaft bearing housing is retained with a Philips head screw on one side and a slotted hex head bolt on the other and neither will budge, thus rendering camshaft removal a little challenging.

Has anyone seen and overcome this issue? Interesting to note that the good book describes the previously mentioned fasteners as cap head bolts.

Do you have an impact driver? I am thinking of the style that is stuck with a hammer on end, forces bit down and turns. That and heat. Of course I can honestly say on some tough ones I have shattered the bit, so make sure it is a snug fit.

Use grinding compound when using the impact, so that it doesn't slip. Make sure it fits perfectly.

Yes, Phillips and slotted come with numbered bits to match the fastener.

Mike's XS sells a nice kit. http://www.mikesxs.net/product/35-0095.html
It has #2 & 3 Phillips (long & short) and #8 & 10 slotted.

A properly fitting bit makes a BIG difference! (And don't forget the grinding paste)
