Title: 1973 Glastron, flywheel removal
Post by: Nolan Kramer on July 06, 2020, 08:12:29 AM
HI everyone, long time reader. I have a 73 glastron with a 12JE and 351w. I had a four post solenoid fail and leave the starter engaged with the engine running for more than i wold have liked before getting it shut off. Long story short the ring gear needs replaced. I am pretty handy but i am trying to avoid pulling the engine due to garage limitations as well as height of the boat plus trailer plus engine for the hoist. Is there any way possible to leave the pump and engine where it sits, unhook u joints remove that black bracket around pump remove bell housing and flywheel bolts and flywheel? or am i just totally dreaming here. Thank you in advance

Yes, that's about it.  You will need to support the back of the engine.  I usually use the cherry picker.  The engine doesn't need to come all the way out, but you might need to remove the motor mount bolts into the block, so that you can get the driveshaft disconnected.  If you have through-transom exhaust, one end of the hose will need to be removed.

Thanks, got it out, waiting on new ring gear. Torque specs on the four 12 point u joint fasteners to the flywheel? i think the flywheel allens are 75-85, same for u joint bolts?
