4.9 Gearbox Motor Maintenance
Service procedures for the gearbox motor require special tools and
skills. Contact your local dealer for any gearbox repair work. DO NOT
disassemble or modify the gearbox as this will void the warranty.
The initial oil should be changed after 50 hours of operation under load.
Subsequent oil changes should take place after every 1000 hours of
operation.
1.
CHECK the oil level by removing the oil filler plug. The oil level
should be at mid height of the input spline.
2. If low, add
85W-140 5EP
grade gear oil. Check the oil level every
week.
