[SEL] Need Help with 1-1/2 HP Petter

[Larry Anger]

Paul - My Son and I removed several just recently and we didn't use the key stock method. We just lined it up by eye very carefully and drilled.  Drill your hole only about 1-1/2" deep. Just enough to tap the threads for a bolt. If you can get a 5/16" or 3/8" bolt in the key it should come out. Use a Grade 8 bolt if possible. It should work out OK. Just take your time.

Larry if you read my last post to Jeff Alan you will note that my greatest 
fear is drilling off center and going through the hub of the flywheel. I 
don't have enough empty keyway to use a piece of center drilled keystock for 
a guide. Also if you will look closely you will note that the tank on the 
end is bent outwards from me using a gib key puller on it so I no longer 
have a nice square perpendicular surface to start trying to drill a straight 
hole.

Thanks.

Paul
