Foreword
This manual provides in condensed form, service and maintenance information which will serve to guide a serviceman when repairing or rebuilding Sperry New Holland L-35, L-775, L-778 or L-779 skid-steer loaders in the shop and to help him when diagnosing and correcting service difficulties in the field. The operator's manuals and assembly information provided with each machine should be used in conjunction with this manual, as much of the information contained in this manual is condensed or supplementary in nature. The following service information can be found in the operator's manual for the specific skid-steer loader being repaired: Electrical wiring diagrams, Electrical system operation, Throttle and choke adjustments, Governor adjustments, Boom lock system adjustments, Oil recommendations for engine and hydraulic system.
Introduction
Sperry New Holland skid-steer loaders feature a fully hydrostatic drive with an in-line back-to-back configuration. Sandwiched between and driving the two hydrostatic transmissions, is a four-way gearbox. It receives power from the engine and drives both transmissions as well as the hydraulic system pump. The transmissions are controlled with two steering levers. The control levers are connected to two neutralizers. As the control levers are moved, the hydrostatic transmission pump pintle arms are stroked to the desired position. Hydrostatic pulsations and the torque feed-back generated by drive train loads are resisted by the internal shock absorber rather than by the operator's arms. This results in smoother operation and significantly less operator fatigue.
