M46 gearbox stiff in neutral
OK, I think I know the answer to this...I've just put new gaskets, seals, etc in the M46 gearbox going into my yellow 245. When I pulled the bellhousing off the input shaft came partly out. When I re-assembled everything I noticed that when I have the gearbox in neutral and turn the input shaft clockwise by hand, it rotates fairly freely for about 1/2 turn then seems to get stiff and the output shaft turns. If I hold the output shaft it seems like quite a bit of friction (ie hard to turn) the input shaft. So, I was hoping this was just because I hadn't filled it with oil yet, but same thing after I filled the oil. I'm assuming the only thing it can be is the bearing in the end of the input shaft where it goes into the output shaft, or something dicky with the first set of synchros. I know the synchro set has those spring clips and 3 small bits that sort of spring load the synchro slider. Wonder if the spring clip came off and is jamming between the input shaft, synchro ring and output shaft? I couldn't see anything amiss...thoughts? I'm certain now I have to at a minimum pull the bellhousing back off and pull the input shaft part way out to see if I can see anything going on there. I don't think I can pull the input shaft all the way out IIRC as I think it fouls the lower shaft. Or, I could just put the whole thing in the car and run it? Hmm.
