Across its 1111 pages, this Bobcat E42 Compact Excavator Service Manual moves through every system on the machine in the order a technician actually works — safety and identification first, then maintenance, then hydraulic component teardown, then undercarriage, uppertructure, electrical, engine and HVAC. Each cylinder section carries its own testing, removal and installation, parts identification, disassembly and assembly procedures, with serial-number splits called out where Bobcat changed the design (for example, boom cylinder S/N AG3411031 & Above versus AG3411030 & Below). The hydraulic chapter opens with a full symbol glossary and troubleshooting flow for the cylinder, swing and travel circuits, so you can diagnose before you disassemble. The engine chapter provides Kubota V2403-M-DI-E3B-BC-5 specifications, torque tables, valve clearance, injection pump timing, compression limits and cylinder head service data in one place.

Hydraulic System Coverage

The heart of this E42 excavator repair manual is its hydraulic section. It documents the variable displacement load-sensing piston pump, the ten-section closed-centre control valve, work port relief pressures, cross port relief settings for the swing motor, the pressure reducing valve that feeds the joysticks, and the manifold / accumulator assembly. Diagnostic pressure tables give the target and acceptable ranges for joystick pilot pressure, system standby, system relief, swing motor cross port relief and more, so a technician can confirm a fault with a gauge before touching a component. Cylinder sections cover testing procedures that isolate internal leakage at the base end fitting — a practical method that avoids unnecessary teardown.

Electrical and Diagnostic Coverage

Electrical coverage includes fuse and relay identification, battery servicing and jump starting procedure, alternator voltage testing, starter testing, lights, magnetic lockout sensor, fuel level sender, motion alarm and the auto idle pressure sensor. Diagnostic service code lists are provided for both early (S/N AG3411001 – AG3413999) and later (S/N AG3414000 & Above) machines, with the number codes and descriptions a technician needs to interpret panel warnings. Deluxe Instrument Panel and keyless start panel setup, password management and maintenance clock reset procedures are also documented.

Engine and Undercarriage Service

The engine chapter covers the Kubota V2403-M-DI-E3B-BC-5 in full — specifications, crankshaft regrind data, Kubota metric bolt torque, troubleshooting, removal and installation, compression checking, speed control calibration, fuel system service including injection pump timing, and cylinder head, crankshaft, piston, camshaft and timing gear procedures. The undercarriage chapter handles rubber track and steel track variants separately, with lug height, tension checking and adjusting, track removal and installation, idler and tensioner service, roller and sprocket replacement, plus a track damage identification guide that explains the causes of common rubber track failures and how to prevent them.

What This Manual Lets You Do

With this Bobcat E42 service manual on hand you can perform scheduled maintenance to the correct intervals, diagnose hydraulic and electrical faults using factory pressure values and service codes, remove and reseal any cylinder on the machine, overhaul the travel and swing motors, rebuild the control valve, service the undercarriage, repair the Kubota engine, and recharge or repair the air conditioning system. Every torque figure, clearance, pressure setting and adjustment value is given in the units Bobcat publishes — metric first with imperial equivalents.

Having the correct procedure and the correct specification matters on a compact excavator. A cylinder nut torqued to the wrong value, a relief valve set outside its acceptable range, or a pump margin pressure adjusted incorrectly will all cause repeat failures and unnecessary downtime. This manual removes the guesswork by giving you the exact figures, sequences and special tool part numbers for the E42.
