Hello everyone, I'm stumped and frustrated. frown

I've been trying to get my SM420 working for a couple days now, have it all together but when I try to turn the input shaft it either won't turn (if the 1st reverse gears is back)or it will rock back and forth a bit. (1st/reverse forward)

If I tap the mainshaft (propeller shaft) forward it shoves the clutch gear bearing out a bit from the case but allows the mainshaft to turn unless I slide 1st and reverse back all the way.

Could it be that I didn't get the pilot end into the roller bearings (inside clutch gear) properly?

If I'm remembering the sequence correctly, the mainshaft assembly did fall out part way after I finished tapping the clutch gear and bearing in. I lifted the mainshaft and jammed in back in. (or worse! would one of the roller bearings falling out (again) cause this problem?)

My mother would wash my mouth out if I said one tenth the words this tranny has inspired. I must be doing something wrong. Any advice would be VERY much appreciated.

Sincerely,
Jacob
