Factory repair manual for the Caterpillar 315 and 315L track excavators, serial numbers 4YM00001 and up for the 315 and 6YM00001 and up for the 315L. The engine sections cover the 3046 diesel from valve train to crankshaft, plus fuel, cooling, lubrication, air inlet and exhaust, and the starting system. The hydraulic section carries the numbers you actually need on the gauge: 132 liter/min main pump flow, 34 300 kPa (5000 psi) travel relief, 31 400 kPa (4550 psi) implement and swing, with Testing and Adjusting procedures to check and set them on the machine. Undercarriage, final drives with Duo-Cone seals, boom, stick and bucket linkage, and full hydraulic and electrical schematics finish it out.
