93 GC 5.2L crankshaft removal
My buddy down the way has a 93 GC with the 5.2L 318 motor. He spun a rod bearing, the rod on number 1 cylinder broke and the engine stopped. Its been examined with a camera, and there is no other damage. After the broken parts were removed, the engine turns easily by hand. Last night we pulled the timing gears off with the chain, and now the crank is ready to drop. He wants to change it for a new one incase the old one got bent.
Question: Does the tranny (auto) have to come off? A local tekkie says the trans can stay on.
Has anyone done a crank removal and re-install on this motor? What is the procedure? he has the Haynes book which is almost useless.
