I have just got my trans back after an expensive proffessional rebuild. I noticed the clutch gear #2513-41 is loose. When I install the clutch base #247241 and tighten the nut, I can feel sideways soppyiness in the splined gear #2513-41, and when I assemble the clutch assembly complete, including the side cover with the clutch operating arm and throw out bearing rod, the clutch base moves in and out about 1/8" or maybe just a bit more. Not the clutch base , but the clutch gear #2513-41 inside the trans. This may-be OK, but not for chain allignement. Any advise from the experts, to help keep these beautiflu old bangers for the years to come.
