50hp oil pump leaking

[superego]

Hey Folks I have a 1985 Yamaha 50hp. When the motor stopped for a few days I notice oil leaking from the shaft coming out of the oil injection pump. The shaft that the control arm attaches to wiggles and pulls in and out. The motor case stops it from coming out further. This is probably the original pump. Are parts available for this pump and can it be rebuilt or should I pay the $168 for the replacement pump. I believe you guys are against disconnecting the oil injection system. The motor seems to run ok aside from this oil leak. Thanks for your imput.

There are not any parts available to repair the oil pump, would need to replace it.
