IH-1466 PTO - Follow-up Still need help

PTO is still not engaging, fliud a gal or so low and filled, made no difference. TA and outlets are working fine, someone asked in my previous post. I took the valve control out and it looked normal. I then drained the hydraulic fluid and took the bolts out of the PTO housing. PTO assy is in two layers about 4-6" think. The outer section seems to come out about 1/2" but does not go any further, the inner section comes out a hair but nether will go any further. I do not want to force and break something. I must be missing something, can someone help me. The pix in my parts manual does not look like what I have, maybe I need to look further. Any help would be appreciated. Also, after I get it out, not sure what I am looking for besides the obvious broken something. Help in that area would also be most appreciated.

Thanks,

Walt

its been a while since ive worked on one and i dont have a book handy,seems to me you have taken to many bolts out of the rear section and not enough from the entire pto unit.the unit should come out as a complete unit from the rear axle housing.look below the pto and above the drawbar.there should be 2 bolts about 1 1/2 inches long holding the bottom of the unit.the unit needs to be lifted and tilted as it is remove to clear the oil p/u tube

OK i would hate to tell you how many PTo"s i have worked on so i can tell you everything about one . First off if you pulled the valve spool out the top then tis is the problem as there is a tinny little pin that holds the two halfs of the valve together and if it came out the top then the little pin is sheared and you need to pull the sway bar support off the tractor and remove the BOTTOM plug under the control valve and DROP it out the bottom and you will have a two piece valve and if you look you will see where that little pin goes and you will have to go to your friendly Case I H parts to get that pin .Now the next problem you have is that you need a special fitting to screw into the test port on the left side of the PTo unit as when you fix the problem you MUST RESET THE PRESSURE for clutch lock up and this is done by screwing the valve stem into the nut that goes on top of the valve stem and the pressure for the lock up on a 1466 should be 250-265 , myself i set to the high side . Now if you do not have a test fitting you can order one from the Case I H store and you will also need a GOOD hyd. gauge that can read up to 600 Lbs . If you try to guesstamate it you may not get enough pressure to lock up the clutches or tomuch and blow the clutch pack out and causing more damage then you want. No you can not just take it apart while on the tractor as to remove the back cover you must tear the whole unit apart on the bench as you have to remove the clutch drum and here again you have to have a way to compress the heavy spring that returns the clutch piston then you remove the snap ring and then let the pressure off that spring and remove the drum . IF you must remove the unit it is wise to use a cherry picker and a short chain and have a pointed pry bar to help level the unit as it comes out . You must becareful when coming out as you MUST TIP the units nose upward as you come out so you do not bang the pickup tube as you can damage it real easy . It would be in your best intrest to get at l;east a IT manual on this tractor . OR let a pro do tis job It takes me from start to finish 4.5 hours to tear one down and do a total rebuild on one and put it back in the tractor refill the Hy Tran and warm it up to operating temp and set the pressure and that is another thing the hy tran must be at operating temp when making the pressure set to get it wright
If you have problems and want to talk to me tomorrow mornig then either post on here or the I H board looking for me and i will give you my E/Mail and i will E/Mail you my land line
and you can call me .
.

Thanks, I appreciate the information. Guess I am screwed on a simple fix as the gasket on the outer half is broken. I do have a bob-cat to help remove, but may elect to take to an IH repair shop at this point. You can email me your phone at [email protected] and I will call you in the morning. Please tell me the time to call.

Thanks so much for the info.

the whole pto comes out as 1 unit. there is one shorter bolt at the very bottom that you might not see at first. when all the bolts are out it's still a snug fit at first but then she'll slide right out. pretty heavy though. and like vet said make sure to tip up the nose.
