Title: Leaks from motor areas
Post by: Hydros on March 04, 2004, 03:10:11 AM
If you find fluid around the outside of your block and motor areas, check out the pump seal.

Oil leaking into the motor will cause damage.

A fix to help prevent oil from entering the motor erea is to allow the oil to by-pass and drip down away from the motor.

This is an older Stone block, but I hope you get the idea.

The blue lines represent the passages ways as they are drilled through the block.

Thanks, I'm not sure, it was about 25 years ago I did this.  

This is also done to some automotive parts. I also notice this appears to be done on some other hydraulic pumps, but the leak is not external.  I believe it is allowed to flow back into the intake of the pump.
