A32978 Valve assm.

[lrobry01]

I want to remove to clean/replace O rings in part # A32978/A59600 (CIH new#)on a 66 730 CK. Need to know if I need to remove A33382 (Trans.Cover)in order to remove A32978.I see it as loosen Hyd.line connection, remove 4 bolts, unscrew parts A32980 front control Spool from A32981 Spool end, move valve assm. (A32978) forward/upward, watching out for 4 orings under assm. Reason is 3 point arms movement is slow in starting the moving up/down of arms, there is no issue with how much weight I'm working with. Would like opinions/advice in this issue. Thanks Larry.

You do not need to remove the valve from the tractor. Remove the square cover on the right side. Four 5/16 bolts hold it on. Kinda tough to get a wrench on them. Throw the bolts away and put allen head bolts in. Behind the cover you will find 3 holes. Front hole is the lowering poppet. DO NOT MESS WITH THIS!!!!! Second hole is the check valve and seat. If it holds a load up this is fine. Rear hole is your problem. Remove take apart and clean. Set the needle to specs in the service manual. Something like 1 1/2 turns from the bottom. Adjustment is a guess so check first! This is the 2 speed lift control mechanism that causes the 3 pt to lift slow for the first little bit and then shift to lift fast. 15 minute job once allen head screws are in there. I have done this many times on my 970. That slow lift while blowing snow will test you. Let us know how it goes for you. DK

Allen head bolts would have made the job simple huh?
