NOTE:
The disassembly and repair of the Sundstrand BDU 10 L hydrostatic transmissions is
best left to a qualified Sundstrand repair and service facility. These repair
centers are equipped with the necessary tools and service information to accurately
perform all service required. Due to the precision nature of these transmissions,
field repairs cannot be recommended.
MAINTENANCE SCHEDULE:
To insure a long and trouble free service life on all the components used on

or each (40) hours of use:
1. Drive system, belts and controls.

4. Hydrostat oil.
5. Tightness of all nuts and bolts.
