INTRODUCTION:

This manual has been written and illustrated to help you, the serviceman, in troubleshooting and servicing the SL4010 Series (SL4510, SL4610, SL4515* & SL4615*) Skid Loaders. The material in this manual is the latest in factory service information. It has been compiled by our factory Service Department and Engineering personnel to give you the best service information available. Follow all procedures carefully, to avoid unnecessary delays and/ or damage to the equipment.

• Where procedures are given in a step-by-step manner, follow them in the order given. Although we have outlined assembly and disassembly procedures for you to follow, there are probably alternate methods that could also work. The Hydraulic System and the Engine are the two most important parts of an SL4010 Series Skid Loader.
• When any service is performed on the Hydraulics System, always clean the hydraulic component and fittings, before disconnecting any hydraulic lines. Contamination is the greatest cause of failure in Hydraulics Systems. For any Engine repairs, consult your Ford or Perkins Engine Service Manual.
• The SL45 l O or SL45 l 5* model Loader uses the Ford 98 CID Gasoline Engine. The SL4610 or SL4615* model Loader uses the Perkins 4.108 Diesel Engine. The Model and Serial Numbers Plate, for the SL4010 Series Skid Loaders, is located inside the Right Chassis Riser, between the Lift Arm and Lift Cylinder Pivots.
• “Right” and “Left” are determined from a position sitting on the Seat and facing forward. From this position, the Traction (Propulsion) Control T-Bar is on the “left” and the Lift/Tilt Control T-Bar is on the “right”. The Ford 98 CID Engine has an identification decal affixed to the right side of the rocker cover.
• The decal contains the engine serial number, which differentiates that engine from any other. · Besides the serial number, there is the displacement (that determines the engine specifications), the model number and, the SO (Special Options) number (which determines the parts or components required on this unit). When requesting information or ordering replacement parts for this engine, BE SURE to provide all the numbers.
