I have an oil leak at my RD-1C redrive.
Took the drive off and noticed the large O-Ring was bulged out in one area between two mounting bolts.
The RD-1C Manual/Parts List specs the O-Ring as 5.125" O.D. x .190" thick.
Has anyone ever replaced this before and/or have a known source of where to obtain?
Thanks for any feedback.
