Mike M may win the prize on the 60 rockshaft piston issue

Mike M may when the prize. On my 60 that keeps blowing out the gasket on the rockshaft piston housing over time suggested to check the pressure of the system. Well I did get a 1500 PSI gauge and used the side pressure ports. The relief valve pressure was way over the required 1210 PSI. In fact I sort of freaked out as it rose past 1300-1400 PSI range. So after some trial and error and a little spilled hydraulic fluid, I removed a total of 4 shims behind the relief valve pressure spring to get the pressure down to right at 1200 PSI. I hope this was the culprit, but will baby the 3 point from now on with the light loading as well.

Thanks for the follow-up Fred.

As far as babying the three point - I've fooled with these old tractors for many years, doing things that the tractor was certainly not designed for - round bales, firewood on a platform, etc. It's not unusual to lift a round bale and nothing raises but the front wheels. I don't yank around on it, but I've had to tie bales on the forks to keep them from dragging off.

Having said that, I think if you get the pressure right it will take care of itself.

We had a model 40 loader on our Mt . The poor steering gear in the front was ground down and missing teeth after years of heavy loads .
