Part of the New Holland Repair Manuals.
The New Holland E26C Service Manual (part number 51605673, June 2019) takes the E26C Cab and Canopy mini excavator apart one system at a time. It runs from the Kubota D1305 engine down to the rubber tracks. In between it covers pump adjustment, the main control valve, swing and travel motors, the swivel, EPPR auxiliary valves, cylinders, the quick coupler and the swing bearing.
A machine sitting with a slow travel motor or a dead work light costs a crew a day of guessing. This book gives you the test pressures, connector tables and rebuild steps.
The sections follow the way a shop works: engine, hydraulics, undercarriage, electrical, then boom, dipper, blade and cab. Large electrical and hydraulic foldout schematics sit at the end.
