your about one step behind the power curve there sheeblast. lol just f'n with ya. get a manual if you don't have one and go to town. it's not that hard just make sure you don't shortcut anything. (always turns out to be an expensive short cut) with all the guys on here and a manual you will make it through with no problem.
Engine problems

I purchased a new crank already assembled, so I have to remove the old crank and install the new one. Plan a is to heat the bearing and freeze the crank and slip them together. Plan B to make a crank install tool by welding some treaded rod to a spare nut that will tread onto the crank and turning a piece of tubing in the lathe to slip over the crank and contact the inner race of the crank bearing. I have a service manual and have split case before, just my first time for a blaster. I also have full access to a machine shop and that definitely helps.
I wasn't saying you were wrong about not being able to rebuild a crank himself. He had just said he bought a weisco crank sheeblast
Parts are starting to come in and I have the cases ready to split for tomorrow. I need to borrow a impact screw driver to remove the stator plate screws and a few others. I found the counter balance gear a little loose on the plate it is riveted too. I think that is were some of the noise was coming from. The crank bearing on the flywheel side had some play in it as well. That brings me to a new question. The balencer bearings seem to have a little play in them, is this normal or should they be snug?
Well I have it all back together and running like a champ. It had problems-o-plenty. The post mortum of the engine showed bad crank bearings, a bad seal on the flywheel side, a crack in the cases between the counter balance compartment and the crank case allowing an air and oil leak, worn out balancer bearings, rings gapped at .090, and the ring location pin inn the piston was broken. Got a used set of cases, new crank and rod assembly, new piston rings assorted bearings and a full set of seals. Engine is good as new now. I purchased the quad for 500 and have that in the motor now, oh well.
