tore apart my R

[mustangmachanic]

i was jumping it and lost third gear and the top end has been noisy .
It was pretty easy getting the engine out of the frame but the top end was
pretty stubborn. Then i started to get a lil nervous..... Id never done this before
i split the case with a small chisel and the "worm gear" and the smaller of the two gearsets came out with a shift fork attached. Afterplaying with them figuring out how they went together i inspected all of my gears. They were fine
so i am asuming i have a bent shift fork. As soon as i can spare some cash i need to buy a manual and a gasket set. Also i plan on doing the crank bearing if i can find one at a reasonable price money is tight and it sucks. A new piston is like $130 not to mention to have the cylinder bored.

Good luck on the rebuild man, mine is apart too. Any pics of your R? Hows the DG head perform? I always thought those were cool.

How does the gear on the shift shaft look? Are there any cracks in the gear?

Never ever use a chisel, screwdrivers, ect to split the cases. You will damage the mating surfaces and have oil leaks.

i know it was a little risky but i used a thin chisel and tapped around the block many times as not to damage th mating sufaces. My R ran well it easily took 300ex out . Ive never had one with a stock head so i dont know how to compare. Ive rode long rides in the mountais without any overheating in early summer.40+miles rough terrain and mountains.

Get a manual.

also...use the dirtcrasher method and stonegrind those edges to remove burrs. You won't have oil leaks then from the chisel.

[mustangmachanic]

what is the correct way to "split" a case? and there are no cracks in any of the gears
there are no burrs but one little dig in the case before i seal them back together i will epoxy the
mating sufaces with a thin coat and then wet block them perfectly smooth and true

Your supposed to use a case splitter to hold pressure and a urethane hammer to lightly tap the case here and there and it just comes right apart.

A steering wheel puller might do the trick.
