View Full Version : Help With HYDRO Repair

08-30-2010, 06:15 PM
I recently bought parts to fix my John Deere hd45 hydro pump(pump rotor and new filter). Cleaned transaxle and pump in parts washer and by hand. Put pump back to together and tried my best to bleed the system of air. The repaired wheel/motor spins slower than the non repaired wheel motor and then slows down after about a minute or two while on jack stands.

What is the proper technique to fill a completly empty transaxle unit with fluid and bleed the system of air? Thanks
