How much clearence are the pump gears supposed to have? I broke a set that was in a brand new pump. New pump, new gears, new stator support. After looking things over I found that the new pump with the broken gears had hardly no clearence at all. .001 on the driven gear and .005 on the drive gear. I looked at the pump and gears that I had been running for 2 years with no problems at all and it had .005 on the driven gear and .025 on the drive gear. Same converter used with both pumps. Could the new pump with the tight clearence be the reason the gears broke? This is the only thing I can find different between the two pumps.

posibly it was installed backwards and the convertor lug was hammering onto the gear. there would be some vibration in and out from your crankshaft at burn out. it could also be in your engine thrust bearing. just a thaught
Gear was installed correctly. This is the same transmission that had about 100 runs on it with the other pump and no problems. Same converter, same flexplate, same engine. I am putting the pump back together with the old gears that I had no problem with. I just think there was not enough clearence
