hydraulic troubles again
used the crawler a few times and noted the oil level increasing again and the hydraulic oil decreasing, I suspect that the pump is throwing hydraulic oil into the engine again for some unknown reason. I have an original owners manual and it says to use SAE 20 oil in the engine and SAE10 oil in the h...

If you open the barrel bung inspection cap you can see it turning, but when the levers are moved it just keeps spinning and nothing happens?, thinking maybe the linings are slipping or...

gearmatic winch installation on 440 crawler
I just restored a gearmatic winch and am in the process of installing it on the crawler, took the cover off the PTO housing and see that there is a male 21 spline shaft. On the John Deere winch mount there is a gear on one side to mate to the winch and on the other side there is also a 21 spline mal...

They were very hard to...
