Oil change after hydraulic leak

Postby stevey30 » Mon Sep 28, 2015 9:24 am

Well found my pump was leaking into crankcase,have rebuild kit ordered from TM,but my question is do I need to do anything special as far as the oil change goes.I know new oil and filter,but is there any other steps to make sure all the hydraulic fluid is out of the motor?Thanks as always for a all the help.

I would change the oil and filter cut grass once and change oil and filter again.

Nothing else needed. Just drain the oil drain out of the crankcase.

The hydraulic oil is already mixed in with the motor oil. The tiny amount of residual hydraulic oil in the remaining motor oil won't hurt anything.

Yes, the amount of hydraulic oil left in the engine is so small it's not worth worrying about.

Maybe if it was something abrasive, it would be worth worrying over, but they don't call it hydraulic OIL for nothing ;)

Just a normal oil and filter change.
If you are not part of the solution,
you are part of the problem!!!

Short term won't hurt. Some old time mechanics like to run ATF in an engine to clean it out. Not much different than some oil additives.

Basically, hydraulic oil just thins down engine oil.
