If I ever get the fly wheel off my 1969 18 horse Evinrude. I will need the proper fly wheel nut torque. Does any one have that.? The model number is18902d thank you in advance.

Never smack a puller with a hammer!!You can snap the crankshaft dowel locating pin/s and fracture the lower ceramic seal...

You won't break the dowels when hitting the puller with a hammer !!!

Been doing it for years if you lift up hard on the puller at the same time you will not damage anything.

Please explain to me exactly how you pull up on the puller.? How do you grab it/ hold it.? pull it? with what.? thanks

Well, I have the puller cranked down as hard as I can. I ran ropes through the puller and lifted the motor, boat and trailer off the ground. I also put penetrating oil on the shaft. I belted the big screw with a hammer and the flywheel is still tight. I have never had a flywheel that was this tough to get to pop. Thanks for all your help.

You never use heat on a flywheel as you can screw up the magnets !!

Heat should not be required at all.

I guess they taught a bunch of people wrong in service school........

Fast----- the crankshaft moves freely though the bearings that are doweled in place.---The bearing with dowels are not thrust bearings for the crankshaft !!--No way that will break the dowels for those bearings !

That I know ...was taught in OMC school(Morrow ,GA) that on the smaller motors that is is possible to break the dowels, whether it can or cant I never hit one with hammer..
