crank case bolts

Post by Mark.S »

I'm just about to split the crank case, i have removed 11 x M6 bolts, are there any more as it doesn't seem to want to come apart.

Thanks
Mark

There is at least one under the generator rotor as I remember.

it's seperating all the way around except at the cylinder base at the front, Is there a location sleeve or something in this area? I've taken the M6 bolt out at the front.

It's very likely that the crank main bearings are being obstinate. Either on the crank or in the cases. BTW you should replace these as a matter of course when you rebuild as they are so relatively important and cheap.

Thanks Steve. I will replace the main bearings.

There wasn't any more bolts, The problem with it not separating was because It was holding on the location bush at the front! I put a couple of the bolts back in at the gearbox and tapped a stanley knife blade in at the join at the front and it cracked open about 5mm. I then made a wooden wedge and hammered that into the opening.

Any way, all apart now, bit of a clean up, order some new bearings/gaskets and build her up again.


Cheers
Again
