This is the factory repair manual for the Caterpillar 313B CR hydraulic excavator (serial prefix BAS, built roughly 1999-2004), the compact-radius machine with the Cat/Mitsubishi diesel. Inside you get actual teardown coverage: engine overhaul with air inlet, turbo, cooling and fuel systems; the main and pilot hydraulic pumps, control valves and boom/stick/bucket cylinders; swing parking brake and straight travel control; final drives, travel motors, front idler, recoil spring and track adjustment. There is a full disassembly and assembly section with required tooling listed, plus electrical and starting system coverage and the monitor panel. If your 313B CR is losing hydraulic power under load, running hot, or the swing is getting noisy, this is the book the dealer techs used.
