Trick to opening crankcase?

[Icefishr]

ok we have all the bolts holding the crankcase together other than the 3 holding the magneto on. However we can not seem to break loose the nut infront of the magneto so we can get to those screws due mostly to the crank turning. we have tried removing the pistons and putting a bar through the arms to hold the crank in place but the nut will not budge. do you bolt the crankcase down to something inorder to hold it inplace so you can get some leverage on this nut?

what do you do or is this an abnormal situation?

thanks

That nut is torqued on there and secured also with Red loc-tite... Your easiest solution is to get out the impact gun, that will give you enough momentary force to break it loose without torquing anything across the length of the crank. We wound up taking it to the dealer to have them pull the flywheel for us (you need a specialty puller to remove it)... they had it off in about 5 minutes and we were then able to pull the stator and split the cases.

ya use a impact driver. and if you cant get the flywheel off heat it up, we broke many tools trying to get it off but after we heated it it popped right off.

Some small pullers like for a steeering wheel etc will work,saves trip to dealer.

you put a bar thru the arms???

I hope your crank was already shot.

me too, can't think of anyplace where it would be safe to put a prybar on this.

I wouldn'r recommend this either. The retention glue that holds the magnets to the flywheel is already suspect and heat on the flywheel will.....

Use the proper flywheel puller for the job so you don't end up like a guy here did a couple of years ago that threaded his puller bolts right into the stator. Ouch
