FAQ

Specify the **applicable** lubrication requirements for the hydrostatic unit. keyboard_arrow_down

Use Type A, F, or Dexron automatic transmission fluid for the hydrostatic unit. Ensure the fluid level is maintained correctly according to the dipstick markings and service intervals outlined in the manual.

What is the **exact** testing parameters for the charge relief and implement relief pressures? keyboard_arrow_down

The charge relief pressure should be between 70-150 PSI, and the implement relief pressure should be between 700-800 PSI. These readings are taken with the tractor engine operating at close to full speed.

Calculate the **specific** diagnostic procedures for a "no charge" condition on the alternator. keyboard_arrow_down

If the ammeter shows no charging, disconnect the rectifier plug at test point 6. Test the AC voltage at the plug with the engine running near 3600 rpm. If the AC voltage is less than 28 volts, replace the stator. If it's more than 28 volts, replace the rectifier and regulator.
