318 LA rebuild after losing a valve seat
Well, another chapter to the 71 Scamp is about to begin. While attempting to install the torque converter, I was encountering some trouble. The pump gear on the TC just wouldn't engage with the input shaft (am I saying that right?). Anyway, I finally gave a closer look and saw two things. The splines on the input shaft were less that pristine, in fact they looked damaged. Also, the pump bushing looked to almost have a chamfer all the way around the first 1/16" or so.
I removed the trans pump and my suspicions were confirmed. Upon closer inspection, the splines on the input shaft have definitely been chewed at some point. I think that explains why I had such difficulty getting the TC on.
Also, upon closer inspection of the fluid in the bell housing, I found glittery material the same color as the bushing. After removing the pump, the same glittery material was behind the pump. That leads me to believe the damage to the bushing wasn't done by me trying to install the TC, but while the engine was running.
I'm taking the pump and TC in on Monday to see what can be done with the pump shaft, and to inspect the splines inside the TC.
