How to remove PTO housing 310 Utility

45cole · Jul 9, 2019

I have a 57 case 310 utility that I was hoping to remove the rear end pto housing so I can check out the rear end for debris/nuts and such. New to me tractor so I'd like to look her over. I see that the PTO shaft has a c clip retaining the bearings in, but I assume that the housing can pull off with the pto shaft still in place?[/img][/list][/code][/url]

On mine you drain the oil out of the rear end then remove eight 3/8" bolts from the housing and pull it off. Not much to it. Long PTO shaft to get past the transmission, you need to line it up putting it back.

With the top cover off that the seat attaches to you can get a good view what is in the bottom and clean with a long handled parts brush after you drain it.

Mine is a one piece from the front of the seat over the rockshaft cover. I assume I'll have to play around with the linkage on the rockshaft? It does look like it gives a good look into the rear end though.

You don't want to pull the PTO assembly just for a final drive inspection as the PTO drive shaft is about 40" long with splines on the drive end. To reinstall the PTO assembly it is good practice to pull the hitch cover so you can guide the spline end on the shaft through the seal. A damaged seal will allow the torque tube hydraulic oil to leak into the transmission sump, this is a common problem with these tractors.

To remove the cover disconnect the links at the end of the lift arms and the other attachments. You'll be lifting the hitch cover which includes the rockshaft, piston/cylinder assembly, and lift arms as a unit.

This is a partial view of the final drive area with the cover off.

Joe's pics are much better than mine, but then mine were taken with the diff almost completely full of hydraulic oil 'cuz my hitch piston was leaking badly. I'll just add that if you have to pull that cover Neanderthal style like I did, remove both lift arms first. It's still a pretty good double armfull. I doubt I could have picked up the whole assembly with the arms.

Sheeeesh Kevin, that is what shop cranes are for. They are cheap and make many of these marginal weight lifting chores fast and easy. Otherwise if you keep it up your gonads are going to be dragging on the shop floor as you head into geezerhood.

Anyway 45cole, if you want to pull the lift arms the splines are indexed so not too hard to get them back on in the same position.

Thanks guys, don't think I'll pull the PTO assembly after seeing the pic of it out. Seat cover shouldn't bee too bad, I've got crane and I'll pop off the arms on the rockshaft. I really appreciate the advise and experience.
