case 970 shifting issues

[coboondocker]

OK guys I came upon a 1975ish case 970. The tractor has about 4500 hoursand starts and runs like a top. However, when i push in the clutch it basically does nothing and feels like there is no pedal. It drives fine with the range in second and the power shift in second. If I try to go into reverse it stalls, and into any other power shift gear it moves but bogs down the engine. When I try to shift the four speed it grinds like crazy unless the engine is off. Another weird thing is the three point won"t go up and seems stuck because I can"t even get it to go down standing on it. Hydraulic fluid is good in the sight glass. Any ideas are appreciated. Thanks!

The tractor has problems with a sticky pilot spool or spools and or clutch pack issues. Either way a proper pressure test needs to be performed by someone familiar with the system. The 3 point hitch could be a broken cable or control linkage. Rod.

I also found that the front hydraulic filter, the red one, has no pressure relief valve. What happens if there isn't one?

If the pressure relief is gone the oil can bypass the filter through the open end. This of course allows all the contaminants to head right to the steering or powershift system. It is imperative that you get a replacement and they are very salty. This is one of the things contributing to metal in the powershift body pilot spool lands causing sticky pilot spools. The more I read and how many time I have found the same thing, I may have to recommend the filters be changed by someone who has a clue.

Cleaned all the valves and changed the fluid and filter she works pretty good. Now just have to get the 3 point working. Big thanks to all you guys for the support saved me some big $$$!
