Wheel Motors

Gently rub some of the black paint off that label to see the brand. .

Was in a hurry thanks will do.. And thanks again for the offer on the hydraulic puller.. Looks like it's a Parker..

 

[marrt]

Yeah, I thought so. Can you peek at one of the other motors without pulling the hub? While these motors are interchangeable, as you know I'm sure, I haven't heard of PT using Parker motors before.

 

[Barryh]

I'll do that to make sure they are all the same. I went online and found a couple of sites that sell Parker's. I don't see my particular model. Being Sunday I sent them an email to see if they have a rebuilt motor, they claim to have over 150,000 units and most are not listed.

Will probably give them a call too, if I don't hear back by tomorrow. Good luck replacing your motors..

You might also check with PT on Monday. Based on what others have reported, their price to rebuild the motor isn't too bad. It's a fairly straight forward job and you know who you're dealing with as opposed to a random repair shop.

Called in on Friday and talked to Terry he was suppose to get back to me.. Will be giving him a call back on Monday also... Thanks. Yes all four motors are the same Parker's ..

 

[marrt]

That's good news since it suggests these are the original motors.

There's no good way to bleed new motors. Fill it up before the install. It will be spongey for awhile but the air does get flushed out via the case drains and the pressure cycling.

Just don't expect to stop instantly when you first start out...

All the best,

Peter

Thanks Peter

That's what I figured. A lot of the oil drained out in-spite of my rubber banding the hose ends with plastic wrap.. Since I've never done this before.. Just wanted to double check that there was not any way for air to circulate around and get into the main drive pumps and do damage.

Called Terry back they could not find a part number for my old 1425 Parker wheel motors.. Terry said they have tried to rebuild these motors before and it did not hold up.

Terry said he had a customer with the same problem an older machine. Instead of replacing all four motors they suggested a White P-141-x12 wheel motor as a replacement he said he couldn't guarantee it but, the customer did report back that it worked fine and he couldn't tell the difference.

I also had to buy a new hub to fit it the old hub can't be used. So both are on the way.. Guess with an older machine I'm going to run into a few of these issues.. Hope this motor works well and holds up.

It is not a bad idea to buy end caps and plugs for each size. I try to have at least four of each size.

That's on my list Ken Thanks ..

OK finally got the old motor off with a few of the suggested tricks from members on here. And the new wheel motor on and my new loaded tires installed. And all is running nice and smooth again.

At first I though I was dead in the water.. The new motor would not fit in the mount area. It was much longer than the old one. A fitting was in the way it was attached to the left side lift cylinder so I removed the cylinder pin and took the cylinder off and moved it aside. While I was in there I cleaned up and painted a few places.

I had just barely enough room to get the new motor in place by maybe 1/8 of an inch. I also had to reverse the large cylinder pin for the extra space. While I was in there I found a rubbing hose the coating was gone. So I wrapped with electrical tape and inserted a smooth piece of plastic behind it to help protect the hose.

I torqued the new hub down onto the motor shaft. It went on to easy so I'm still a little nervous about that. The carter pin hole on the new tapered shaft was smaller than the original motor shaft. I put a stiffer style pin in the hole. The new motor had no case drain so I plugged up and tied off the old hose.

The vibration I had under load is gone and the PT seems to run very smooth. So far I see no leaks anywhere after running it around the property for about an hour. I felt pretty confident I could change out the motor after reading through various old posts on this forum.

But I want to thank everyone on here who gave me tips and helped me get her back up and running. A special thanks to Kent T for emailing me with some added directions. That made the job so much easier than it would have been.

Since my old motors are obsolete and Power Trac removed the labels. I still have no idea what motor this is other than it being a White. So I plan to eventually cut off the old mounts and upgrade the old motors and follow Kent's lead.

Now on to other upgrades like a Rop's and replace any old hose's etc.

I gotta say I was going through some serious PT withdraw, it's nice to have the old girl back up and running.. Had some pictures but wouldn't let me upload for some reason.

 

[Barryh]

All of a sudden I can upload pic's to go with the above wheel motor post / install. The pictures were not in the order I selected but you can fill in the blanks. Hopefully this may help someone else with an older machine.

Shows the difference between my old Parker Wheel motor / hubs and the newer White motor with thicker hubs, sent to me from Terry. The newer motor did not have a case drain so I had to cap that hose off.

The motor was too long I ended up having to move the lift cylinder over and the pin out of the way so it would fit into the mount area. I only made it by about 1/8 of an inch. After I turned the pin around.

So far the new motor is working great and I can't tell the difference. I have installed my new loaded tires they seem to be very stable easy on the grass and I really like the ride over the Bar tires that originally came with the PT.

I also just ordered a new seat, the same stock seat but with arm rests. I like the stock seat because it has length wise metal backing more protection for my back in case of a engine fire etc.

I will be upgrading gradually starting with a Rop's in the not so distant future. Once again thanks for all of the tips and help.
