Hydrostatic pump failure in C model

[bannersprings]

hello all

i have a 2006 C model Toolcat with 750 hrs that has just been diagnosed with hydrostatic pump failure. the BC service dept in Las Vegas found the telltale brass filings in the filter. does anyone know if this is a common problem in C models i.e. are these pumps defective?

my service rep tried to get BC to pay for the new pump but no dice. the district rep says that BC ended a factory replacement policy for first owners in february. now i have to pay $4k to replace the pump.

if i can document that BC knows there is a problem with these pumps, i will probably take legal action against the factory to force them to replace both pumps for free. does anyone out there know anything about these pumps?

thanks

It is a very well known problem in some of the C series. Bad batch of motors from supplier. I would start complaining loudly. You have very low hours and they may fix it. Do a search under the TC forum.

thanks for the info. this a.m. my service rep told me the problem is with the hydrostatic motor not pump. Bobcat told them to remove the motor and inspect for piston play, which was considerable. also recommended replacing both motors at the same time.

still waiting to hear if Bobcat will pay for repair or not....

Since hydrostatic trannies are a close loop system. when one component goes it typically destroys all others in the loop. I.e. motor fails takes out the pump and vice versa.

To repair properly all of the HST hoses need to be cleaned BEFORE new components are installed. Putting new components in with the dirty oil in the lines will potentially cause them to fail prematurely.

good luck
