JD 755A Track Loader

Okay, here's the deal.

I have found a 1983 755A with 6100 hrs, right side won't pull under load.

New tranny (15k) in 2005 at 5300 hrs.

"Supposedly", new drive motors (not sure about this, rumor).

Looks good, engine runs good, coolant looks good.

Issue: J D Dealer says if it is an internal problem, would run about 20 k ...per side. Ouch!

Dealer also says a tech could tell in about an hour whether the problem might be a flow adjustment which might solve the problem. If not adjustable, then the 20k applies.

Problem is, the machine is out of state and a long way from nearest dealer. Nearest Dealer wants 1000.00 for a service call.

I can get the machine for under 5 k.

Worth a 1000.00 gamble?

Thanks in advance.
