I can't win with these TC pumps
The replacement one I bought failed. Its leaking into the oilpan again. I don't know what it is. I rebuilt my TC unit and when there is fluid inside, the damn thing works like a dream, but after about an hour of good use in the snow, it just has trouble lifting the plow and eventually, it stops working.
I could go the route of replacing the seal, but I did that last time on my old one and it didn't work.

Re: I can't win with these TC pumps
I gotta be honest, I never heard of repairing one of these pumps until I got to looking at tractor stuff on the www. Not saying it was never done, but usually a leaky pump = replacement, which is painfully expensive but you have a new pump. Hope your luck improves, honestly it sounds like something that would happen to me!

Re: I can't win with these TC pumps
Is it possible when you rebuilt your TC unit something got put in backwards or something got missed and it's building to much pressure to blow the seal in the pump? That happened to my brother one time.

Re: I can't win with these TC pumps
When you remove the pump and dissemble it check the shaft closely for a groove, if there is one there, and especially if it has a ridge in the groove, use a Dremel abrasive buff to go around and around the shaft to smooth the groove.
they are short lived, normally just last for a coupe TC shafts, but are worth the money. They can be mounted on an EZ Lock or standard mandrel either one. If your pump uses an oil seal rather than an o-ring you can frequently get a thinner body seal and mount it shalloer than the original so the seal lip will run in a different place on the shaft.

That is something to check. There are stops at each end of the travel of the control linkage. They need to be adjusted so the system doesn't hold pressure at the ends of each stroke. The adjustment procedure is in the Touch-Control Serviceman's Guide.

Re: I can't win with these TC pumps
There's two pump designs, one uses an o-ring seal and one uses an oil seal. If the shaft is scored and you hone it down to eliminate the score, the diameter will be reduced some but needs to be true round withing .001-.002 or it will cause the seal to "flutter" when running and will leak. Even if it is round, it might leak if the diameter gets reduced enough that the seal is not snug fit. These shafts are heat treated and are very hard, the best way to fix the shaft is to turn it down just a bit on a lathe and then press on a speedi-sleeve. The sleeves are made of stainless, very hard and smooth to give the new seal a good, renewed surface to ride on. The tricky part is getting the speedi-sleeve pressed on to the exact place it needs to be because it's not very long. While you're at it, you can replace the body o-ring and hone the gear faces. If the gear faces or the brass bearings get grooved or scored, this can reduce the efficiency of the pump.

Re: I can't win with these TC pumps
Found the pump on my 130 was defective during the rebuild.
Ordered a used one from a wrecker (Ontario Used Tractors). He said it was off of a C or maybe a Super C, but it would work.
Had to use the die grinder to remove about 1/16 of cast to get the fit, but that pump has been working like a charm so far this winter.
Hope you can find a good used one.

Used the die grinder to remove a small area so pump 383013R94 would fit.

I got a replacement from a scrap Super C. Worked good well after my TC rebuild. It seems that ever since I mounted the snow plow it is doing this. I wonder if I have the linkage above the plow wrong or something causing more strain than needed.

Re: I can't win with these TC pumps
Mike,
Been out for awhile. Did you get things worked out?
Your snowplow looks to be stock hook-up from your pictures.
The measurements you gave me for the boomerang work like a charm.
Is it binding anywhere?
Have not had one lick of trouble with mine. Sure beats the Cub Loboy for sheer pushing power and volume.

I haven't had time to play around with the tractor unfortunately. I've been up at the UMass Ag. school, only 45 minutes from home, but still not enough time to tinker. I'm going stir crazy.
When I have some time I will probably look at this thread again to diagnose the TC problems.

Re: I can't win with these TC pumps
I have never worked on a Super A/140 TC unit, but I assume they have limiters on them to prevent the control levers from going so far the the lift keeps trying to raise or lower it, and the pump is continuously running under pressure. The manuals call for using a pressure gauge, but you can pretty much tell by ear. Run it at slow speed and operate the TC. You should hear the engien load a little then ease up at the end of the stroke when the position of the arm and control valve match up. If it stays under load the hand lever is going to far.

you are part of the problem!!!
