Thanks Wayne.
The pump swash plate still swivels as it would during normal operation. When I drove the pin the sound changed, so I thought it was a stopping point. If you look down the hole the pin appears to be at the depth which would make it centered in the trunnion shaft. Is there any trick to removing the trunnion shaft when the pin is centered in the shaft? If I drove the pin too far, are my only options a machine shop? Thank you.
