Leaking power steering sometimes

[kh2072]

I have a 2072 that I bought last summer. Tractor works great and came with a 60" mower and 450 blower. Sometimes when using the blower to clear the yard after a hour or so of use the steering will start leaking from the dash. If you shut it off and let it sit for a few minutes it stops leaking for a while and all is good. Sometimes I can use it for hours straight no leaks at all. I do not mind rebuilding the steering pump but have never seen hyd. leaks come and go. They either leak or not. I do not want to replace the seals only to find out something else is causing my leak. Since this does not happen when mowing only in the cold winter I was wondering if there may be a relief valve that may be freezing or clogging with snow dust causing a leak at the weakest point. Any advice would be welcome. Thanks.

Its coming....The dreaded PS leak....

Many threads on this and rebuilding it...Parts are cheap....But its timely and tedious.

I fear I am headed there as well. But you might check that the upper clamp on the steering support is tight. I bought a little time as I found the PO had not tightened it when the driveshaft was "rebuilt" mine leaks down low from a gash made in the tube resulting in the driveline rebuild the PO bragged about so much.

Welcome to OCC! Have the same problems with my 1872 leaking. It's getting a permanent fix though.

The hardest part is getting it out of the tractor. If it works fine and only leaks then you shouldn't need to use the shim stock part of the rebuild. Just get you the $50 JD kit and replace the rings and seals but take lots of pics so you get it put back corrrect. The MTF link Randy posted a good read before you start. I have the PDF manual if you need it for the PS assembly. Good luck!

thanks for the info. I have the manual for the rebuild and have read many threads about it but never read about the leak coming and going. I plan on doing it in april after snow before grass grows.
