I fired up the Oxy / Propane torch and heated up the seam.
Didn’t take long and the shellac gave up the fight.
Hmmmmm, will have to look for the 2" cooling line
to see if it’s even there!
Thanks for the warning!
Pulled one piston and rod out of the crankcase yesterday.
Had to heat the rod cap to get the two rod bolts to break loose.
Tried the same with the little bottle torch on the other side,
but they didn’t want to let loose. What’s up with that? Perhaps
someone used thread locker ? May have to try the big
guns on those as well.
Johnson 3rd addition manual mentions "rod cap bolt lock
washers (with tabs to bend over) on one page, then the
next page it says they not used on these models, just torqued
to proper specs……. I have none, and as tight as they
are, they were NEVER going to loosen by themselves, lol.
Prepare to be boarded!
