Hydrotrans leak/problem 3212H

Recommended Posts

callwill
Up until recently i had a small leak. Its now a blood trail that a blindman could follow. If i get low behind the tractor I can see it coming down from somewhere up under the cooling fins. I'm hoping this is a simple fix like a gasket or seal(or tightening some loose bolts) that i can do quickly in my garage. Along with that i have what i hope is a related problem: once warmed up, if i hydro forward to full speed, after about 25 to 50 ft the tractor will start to slow to a crawl & then sometimes climb right back up to speed. Other times it will stop. If i reverse it, it will back right up & then go forward again until it repeats the problem. If i stop it when it slows & wait a couple of moments it will move forward again. I'm wondering if it could be sucking air from where is is leaking fluid. Any ideas? will it be something simple enought to fix @ zero degrees plus or minus 10? or should i have it hauled to a heated shop for serious surgery?

If i'm guessing right, It has a vickers hydro? If so, its not an easy fix. No seals, bolts, gaskets or bearings. You may be able to rig something up to hold an o-ring in there, like I had to do. Takes a while to figure out what to do, but mine has worked 3-4 months now im guessing.

Yes, Vickers. 1970/71 3212H. You didn't suggest where the leak might be coming from. Do you suspect the pintle?(i need to clean the grass & dirt out of there so i can see if that is the "case"-pun nearly unavoidable!)The old slight leak was from the pintle. Is there any other spot to watch for a leak like this? And what do you make of the start stop action? I reviewed the pintle bushing repair info & i guess you have to tear the hydro completely down to effect that permanent repair. Might it be quicker and cheaper? to replace with rebuilt unit?

Do a search for "Vickers" here of the forums. Including the archives. It will provide further info to the help provided by maxtorman. I think you are on the right track though with the pintle shaft. Very common problem.

Yes i had seen that rebush article after my initial post. What does it take to do that job(time & money). How difficult is the disassembly & reassembly if i could do it myself?.What does it cost. Are there rebuilt & bushed units out there & what do they run?

There was a place in Illinois, can't remember the city, that would do it for $100 plus shipping. You send them the pump and the $ and they send it back to you repaired. I have not talked to them in about 3 years though. Member dlcent I think also repairs them or has them repaired. Last I talked to him about it, (also a few years ago) he wanted something on the order of $300 for a repaired one plus your leaky one in exchange. Brent

Thats probably where its coming from, the starting and stopping is just a result from the leak, mine was just pouring out the rear, I had no power at all, it seemed to build up some pressure, then it would our out the back, andI would loose speed. I put an o-ring over the shaft, put a flat washer, then a big lock washer. I then put a blot in the hole in the shaft, turned the washer, and no leak:D. Bent a peice of copper wire and wrapped it around the rod below to keep the lock washer from turning. Works great! only, the copper is starting to wear.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
