The Saga continues...
Decided to mate up the input/clutch shaft and rest of the main case today. The input shaft bearing was
pressed on with little fanfare. Here's a
tool I made out of a conduit strap to keep the pressure on the inner race instead of the bearing area.
I installed the new synchro rings into the synchro clutch drum assembly and
placed it into the case. Remembered the first and reverse
slider gear. Well, not right away, but eventually...
With the main shaft installed in the
adapter plate, I lined up the lugs in the rear synchro ring with the channels in the main shaft
helical gear and everything pulled up tight. I remembered to put the new gasket (with non-hardening permatex) between the adapter plate and the case.
Then it was onto putting the new roller bearings into the case end of the input/clutch shaft. Here are the first set of 14
fat roller bearings installed. I was worried this would be a bugger, but they went in really easy with the "Red and Tacky" stuff I have been using. Also, the shop manual had really good instructions this time, with nothing left out. Use the shop manual for this process. It helped me remember some things (like gaskets).
Next went the small inside diameter
thrust washer, followed by the larger one, followed by the
24 thinner roller bearings. More on this later. Then the
clutch shaft was mated to the front of the main shaft with zero problems. It's like they were meant to work this way...
New gasket on the input/clutch shaft and we were in business. The manual says it's important to line up the lugs in the forward synchro ring with the flats on the input shaft gear. But honestly, I could not get it to go together any other way.
Now comes a question for you gurus on these transmissions: My input shaft
main bearing slid into the hole in the main case with hand pressure. I did not have to use a brass drift as the instructions say. I suppose that means that the diameter of my case hole may be worn a bit. I have no slop in the connection, but worry that I may have issues later. Is this something (a spun bearing) I need to worry about?
And, here's a nice bonus: I had one more thin roller bearing on my bench after assembly. I looked at this
little monster and doubt started niggling at me. I DID put 24 in, right? I mean, they seemed tight, but then again...Yep...took it all apart and rechecked to be sure. I had zero room to add another roller. Must have gotten an extra in the kit for good measure. I hope. Manual calls for 24.
All the
gears seem to mesh okay. Some lash between the idler gears and the countershaft, but there's no oil in the system yet. And, some of the clacking I am hearing right now is probably due to the
synchro clutch being able to slide back and forth without being confined by the side cover forks. Anyone have a test procedure for this stage? To make sure everything is meshing as it should?
Expecting the last OD piece in this week. So next update is for that end.
