So today in the shop class, our class group removed a whole transmission case from a 1994 Harley Davidson Heritage Softail. It's a nice looking bike for it's age and with a little bit of work can be turned over for a little bit more profit, if the owner decides to sell anyway.
The bike starts up and runs but it winds real loud and chippy through 1st and 2nd gear almost identical to the sound of a car going in reverse but with more obvious notion that something is wrong.
It wasn't too much of a process to remove the transmission itself but more so trying to get to it. We had to take the exhaust pipes off with all of the bolts, the primary drive casing, and some of the bottom suspension components to make room for a clean removal. One thing we noticed while in the process was the ball bearings around the input shaft was half broken and busted, and we assumed the rest of the ball bearing pieces were located inside the transmission case itself.
Once we got the transmission out of the frame, we split the casing and noticed some of the gear teeth were chipped and broken off. This is the result of the ball bearing breaking and busting loose. Kind of like throwing a bag of marbles into a food blender. The result, noisy and not too pretty to say the least. Like a dominoe effect, once one thing goes, everything else goes with it. There's no such thing as the weakest link on a motorcycle as everything works in conjunction with each other.
The transmission is rebuildable with new ball bearings and new gears to replace, but it might cost a decent amount of money at new retail pricing, so we might see about getting a cheaper used transmission to put it in. The good thing about it is that it doesn't take too long to put back into the frame and in running order, and that the frame and engine is compatible with other Harley Davidson models.
