I have a 2004 zd21 with 1400 hrs on it. The left drive motor went out price was $1900 parts only. Charge pump, both drive units and add on oil reserve parts about $2600. opted for all parts. Did own work with help from a friend and repaired. New oil, filters ect... Problem first use: couple hrs mowing and charge pump was about 275 degrees hot. Does not seem good. How hot should pump and drives run? Any help or suggestions greatly appreciated.
