So first things first, after cleaning the bull gear, I think it's in rough shape, couple of chipped teeth, some pitting too. This thing has really been through the paces...I think I have no choice but to run it, I don't know how much a good serviceable unit will cost, if I could find one, plus shipping, this thing has to weigh 75 pounds.
Got the front of the tractor all jacked up and on blocks. That was a workout with these cheap old worn out 6 and 8 ton bottle jacks. LOL
So I decided to pull the steering differential assembly, because I found a couple more wobbly gear shafts in there which led me to believe there were more shot and busted bearings in the case, and I wanted to clean the dirty, full of metal shavings sludge at the bottom of the case... So in order for me to pull that out, The PTO shaft, and the PTO bearing (which was shot by the way, it got hot with no oil and had some bluing on it) had to come out, same for the PTO unit itself, which of course is not light.
So this picture here highlights the PTO shaft, underneath it towards the rear, is the transmission, steering diff and final drive oil pump, which also had to come out. Then the 2 great big main caps on each side for the steering differential come off.
Here is the very uncommon gear reduction style PTO drive unit
Here's the whole kit containing everything for the PTO, I may not put it back, I'll clean it all up, rebuild it, and either put it on the shelf or sell it to help buy much needed parts. A lot of these Cletracs did not come with a PTO, so the round cover out back and the rectangular cover on top of the trans case are easy to get.
The bottom stud at 6 'O-Clock, the nut was not there, thank goodness because it would have been impossible to remove, the gear reduction unit sits right there, no tools can fit in there, nothing. I have no idea how on earth you would put a nut on there. So my guess whoever installed it left that one out! it leaked oil at the bottom, it was FULL of HARD greasy dirt clods.
The steer clutch bands are out of the way, the oil pump in the rear had to come out, and I puts these bolts in to help me get a better grip to lift the big giant back braking thing out of there!!! This was HEAVY! (I do not have an overhead crane!!)
Here it is in all its glory. Some of the gears inside are pitted, the bearings are kinda shot and do the shimmy. I just don't know if I'm in the mood to rebuild it...It most likely wont be cheap. I really don't want to deal with gear lash and end play and all that stuff ya gotta do like when ya rebuild the axle on a truck.
Well that's it for now. I have a few days of parts cleaning. My back hurts from lifting that. I shoulda used my Kubota.
