570 case hydraulic leak

JohnAndrew · Sep 11, 2019

I am loosing hydraulic fluid, it is leaking out the bottom of the bell housing at the inspection hole.
Any idea what seal is bad?
Will i have to split the tractor to repair?

THanks

If you're sure the leak is hydraulic fluid then you will have to split and renew the shaft seals #55 & #63 on the hydraulic pump drive shaft. Pic is a 300 just for orientation, you do not have the spring or tach drive and a different style of throw out fork.

Remove the 4 bolts on the cover and the hydraulic pump drive as depicted below comes out as a unit. Also check that bearing #57 is good or just replace with new.

The cover has 3 bolts not four. There is nothing else holding the unit in there although it may take some banging/prying and bad words to break the cover gasket loose.

You may want to drain some oil from the hydraulic reservoir before removing the cover.
