Leaking wheel motor

Good question, Duane. The shop said the gerotor's had enough wear themselves that a seal kit probably wouldn't be effective. However, there was a gash that appeared to have been caused by a piece of metal being pumped through the hydraulic motor. (Apparently, that isn't all that uncommon...???) Anyway, he said that given the wear and the gash, that a seal kit probably wouldn't last very long. I remember the guy that I bought this machine from telling me he'd "had some problems" with that wheel motor. Apparently he did the easiest fix, which was having a seal kit installed.

Regardless, a local hydraulic supplier and this hydraulic repair shop have both said that this Parker TB0230 model is a "throw away" wheel motor, meaning that when it wears beyond repair you just throw it away and replace it with a new one. Wish the previous owner had taken that approach!

Now, note that my unit is 13 years old, and the newer units may or may not still use "throw away" wheel motors. I know the current wheel motors are different (both 422 and larger 425 motors) because Terry had to do some digging for info and actually never did get back to me. So I'm pretty sure they're not still the same model as my old one.

HTH,
Dave

Oh boy...when I took this wheel motor off, I looked to see if oil seemed to be gushing out of the hose. It wasn't, just what was in the hose appeared to run out, then it stopped. Well, discovered an oil slick under the tractor this weekend. I checked the hydraulic tank: empty! Best I can figure, as the oil got warmer and thinner, it started to run out of the open hoses, since the tank is above the open hose ends (ie. gravity plus temperature helped)...now I know. Don't leave any open hoses on your machine (I put a baggie and twist-tie over the open hoses to keep dirt or water out, so by "open" I mean "unable to hold minimal pressure"). I now have about a 7-8 gallon oil slick in my backyard. I guess I'm going to need a couple of gallons of Simple Green, eh? I know now, if I have to disconnect a wheel motor or cylinder, etc., in the future, I'll put a male-to-male fitting between the hoses to keep this from happening again. I simply wouldn't have expected this to happen.

Gregory Pool Equipment called and said the wheel motor is delayed, the supplier is out of stock and has to order one from Parker. I've checked Surplus Center, and I've also requested a quote from Baileynet. Anyone know of any other mail-order suppliers where I might find a reasonable price and in-stock availability?

Thanks,
Dave

Yeah, really. I obviously have a love/hate relationship with this blasted machine!

But that valuable growing knowledge base! We're all so grateful for your research /forums/images/graemlins/tongue.gif All you need now is a backup machine to take the pressure off the parts leadtimes. Ha!

He he...I'll take a backup machine as long as it isn't 13 years old like this one. I think my next tractor will be a new one! /forums/images/graemlins/cool.gif

Anyone have any suggestions on how to clean up this massive oil slick? A couple of gallons of Simple Green? I now have oily mud under the tractor. Unbelievable. I'm still kicking myself for not putting a fitting between these two hoses. /forums/images/graemlins/blush.gif

Dig the dirt out, bag it and get rid of it. I've also heard that DAWN dishwashing detergent does a great job.

Yep...so I hear. We had a big accident here in Cincinnati a couple years ago where a tanker carrying a load of liquid animal fat (?!) overturned, spilling the contents all over I-75. The clean-up crew stood scratching their heads as nothing would get the oil off of the pavement. Proctor and Gamble called and suggested Dawn dishwashing detergent, and that's what they used to finally clean it up...it's a good emulsifier, but I'm not sure how it would work on a petroleum product...

Dave:
Did you ever try using cat litter, I have found it to work real good on small oil spots on my garage floor when I had oil spilled.

similar to kitty litter - speedy dry at your ocal auto
parts store also works great and it comes in 50 lbs bags

good luck
