Clutch & input shaft bearing replacement - Cranking, thud-sound
Car: 1991 Civic Hatchback DX
I removed the manual transmission to replace a noisy input shaft bearing and while the tranny was out, I also did the following: Clutch and flywheel, throw-out bearing, rear main seal, distributor oil seal, and all rubber seals on the tranny housing. I took the tranny to a tranny shop here in Sacramento to have them put back the transmission gears after I replaced the input shaft bearing, just to make everything was put back, correctly. After 1st install is complete, I get this thud sound, decribed below. Anyway, I went thru the whole process, again - removed everything , checked to make sure the clutch was installed correctly (which it was), checked everything else, including the starter to make sure it's good. After installing everything back, I turn the key and I get the same result: The engine is cranking for about 4 seconds and then, a noise like something is hitting inside, like a thud. And it repeats with cranking for about 4 seconds and the thud-like noise. With that, I removed the plugs and turn the engine counter-clockwise. I did not hear anything hitting or a thud-like noise, but you can feel more resistance at certain point of the turning circle (if that makes sense). I also removed the starter and have it tested at Autozone and according to their testing machine, it's good. The car was working fine before this whole process except the annoying noise from the input shaft bearing. I don't know what else to check at this point so any help would be greatly appreciated. Thanks
