I knew cleaning would take a back seat! Once these kind of things are done, than you can clean!

Looking good Daniel, You are moving right along with it.

 

I have located one of the hubs and am trying to remember where the other one is. :wallbanging:

 

They are 1 1/8" bore with 1/4" key way all the way thru. :thumbs:

THANK YOU my GTT Brother!   :dancingbanana:   That really simplifies things for me.  You'll find it I'm sure, as you have plenty of time to think on it.  I am in no rush for the hubs.  For now I'll just put the simplicity wheels/tires on this JB when I'm at the point to moving it around.

Got everything done farm wise early, so I got time to pull the hydro apart.  I swapped the swash plate pins to put the control shaft to the left side of the tractor, then reversed rotation by flipping the charge pump housing 180 degrees, and slicing the grooves in the valve plate on opposite sides.  It now has the grooves in both directions, and I'm not sure if this will cause slight drop in pressure or not, but I guess I'll find out.  If it does, then I'll have to contact Sundstrand for a proper valve plate.

 

In the pic below, you can see the shorter cuts I made, vs the longer factory grooves.

here are general pics of apart, then back together.

Thought I would add to this hydro service.  Some may wonder why I didn't mention making a gasket.  Most times when I take a hydro apart, I re-use the old gasket even if it came apart on both halves.  I am careful not to disturb the gasketed surfaces during my work.  Once all the service work is finished, I spray the damaged gasket surface with carb spray to remove oils.  Then I lightly blow with air to quickly dry the carb spray.  If any oil remains, it will show up as a wet spot.  Simply spray with carb cleaner again, then blow dry till it is oil free.  Then coat both surfaces with Permatex MotoSeal 1.  Let tack a couple minutes, then bolt everything up tight.  I have yet to have a leaky hydro doing it this way, but I only use this method one time.  If it does leak, or I have to take it apart again for another reason, I will either cut a gasket or purchase a new one.

 I have yet to have a leak

Pretty hard to argue with success. I am a big fan of the "forma a gasket" materials. They also seem to make it easier to take apart again if necessary.

What are the specs on the Sundstrands? Pump vs. Motor ? And psi at max? Not the charge pump.

I havent seen cuts like that in the valve plate. All the ones I have seen are like a triangular scoop. I do have a spare 15 series thick   valve plate  if you need it. I think its the motor plate so its bi directional. Was for a MF1855.

I have a spare 15U for parts, but the motor valve plate doesn't match the cutouts in the pump plate.  All previous hydro's I've ever been into had the triangular shaped chamfer also.

Yesterday I installed the hydro onto the diff & used a drill to turn & prime the system.  All worked as it should.  Today I only had an hour or so to do anything to the JB.  So I beefed up the left side where the differential attaches.  The right side is boxed factory, but the left was just the 1/8" metal side & not rigid at all.  I added the C-channel, and 1/4" plate below it where the diff bolts up.  The nuts are spot welded in place to make bolting up the differential much easier.

 I will weld a plate over the open rear of the C-channel, & may also add gussets at the front later.

That will definitely stiffen up that side. Glad you are finding a little shop time every day or so.
