Huber Warco Maintainer Torque converter

corvette99ht · Sep 30, 2019

Can anyone tell me how/where to check the fluid level in my 1962 Huber Warco Maintainer model 52 (belly grader blade type tractor) .... I have the owners/parts book, but it doesn't explain where or how to check the level.

On the left AND on the right I see two 1/4" pipe plugs each side ... one is a vertical plug , and slightly below that there's one at about a 45 degree angle ... total of 4 plugs for some reason.

I do find the two 1/8" drain plugs, one at the bottom of the main case housing and one on the rotating finned impeller. And the book defines the large volume of fluid (10W engine oil) and the process to refill after draining. But I hate to go to all the trouble of draining it all and refilling it, if it simply needs a little added, so I need to know how/where to check the level.

Thank you

Attached is another picture, with the 1/4" plugs I was talking about.

I'm sorry I can't answer your question but exactly what does the torque conv do? I have a machine just like that. I have driven it very little and it drives
just like a standard shift tractor.

The Owner/Service manual says they added the Torque Converter to the design of Maintainer so that it had a smoother operation, less jerky action. The torque converter is a "fluid coupler" between the engine and the tranny/clutch, so absorbs shocks/vibration I guess, and less shock when clutch engaged.

That's a very cool machine, of which I know nothing.

It seems reasonable that the plugs in your picture are for fill and level. But I wonder if you're supposed to check the level with the torque convertor spinning, like an automatic transmission. (My assumption is you check it with everything shut down and cold, but who knows?)

I now attached a photo of the Operator Manual page that describes the Torque Converter.

I use my machine on my .6 mile long gravel driveway. It's just the right size machine for that 1-2 times per year to grade it. Then about every 10 years, when putting down new gravel, it does a nice job, and that's when I use the front dozer blade if there's a small pile/lump to even out while grading.

What will you use your's for?

I find it interesting that you didn't include a photo of the I.D. tag on the torque converter, or mention what it says.

I'm gonna guess Huber didn't make the T.C., and it's a pretty generic unit, likely made by an outside outfit such as Twin Disc.

If that turns out to be true, armed with the manufacturer's name and model number you can search the 'net for a manual for it.

I'm adding pics of the ID tags on the torque converter, one of which calls out the HuberWarco part number 1M-4051 . But my operator/parts manual already lists the Torque converter as made by Fuller, model 12-T , and the Transmission as Fuller Model 5A-330. I also am adding the drawing of the Torque Converter page, which does show the plugs that I took that picture of, and shows one set as "oil in" and the other as "oil out", which I don't understand.
But I've never been able on the internet to find any documentation on the Fuller Torque Converter. It looks like Fuller was acquired by Eaton some time in the late 1960s. If anyone can find info, that might help.
