Track Loader Modification
953-963-973 CHRONIC FAULTS IN HYDROSTATIC TRANSMISSIONS

1. Machine does not run at low throttle and does not make a point turn

2. The final drive group (traction gp.) and hydro motors shafts have a knock in the forward and backward transitions, this knock causes damage and malfunction in the Final drive group (traction gp.) and hydro motor groups in a short time.

3. Since the underspeed valve in the gearbox is not fully installed, the gearbox works under high pressure, and the pressure created causes the oil to heat up. Due to the heat generated, the charge pressure that will feed the system decreases, causing corrosion on the cylinder and valve plate.

In the modification process, brakes and transmission fluid are installed as soon as the machine is running.

After the modification, the machine speed increases noticeably. The problem of not making a point turn is solved. Machine performance is increased by 30%.
