bobcat B200 tractor

[briker57]

I have a bobcat B200 tractor and the inner gear broke in the charge pump Bobcat says that I have to buy the whole assembly which includes the hydrostatic pump the charge pump and the gear pump for a price of $5735.00 Does anybody know who made this pump for bobcat so I could go right to the pump company and see if they would sell me just the gear or at least just the charge pump.I can't find a mfg. name on the pump.
Thank you
