JCB 修理マニュアル

JCB, formally J.C. Bamford Excavators, was founded in England in 1945 by Joseph Cyril Bamford, starting out in Uttoxeter before the company established its headquarters at Rocester, Staffordshire. JCB grew into one of Britain's best-known makers of construction equipment.

JCB is recognized as the pioneer of the backhoe loader, dating back to its early 3C-era machines, and it also builds Loadall telescopic handlers, the Teletruk forklift, and both tracked and wheeled excavators. The company manufactures its own Dieselmax and EcoMax 4.4L diesel engines, designed to meet Tier 4 emissions standards without relying on a diesel particulate filter.

The manuals offered here cover JCB's 100 Series machines, Dieselmax engine service, telehandlers, forklifts and transmissions. Content includes engine rebuild procedures, electrical system wiring diagrams, hydraulic and transmission service, torque specifications, diagnostics and scheduled maintenance routines.

These manuals give independent equipment repair shops, fleet maintenance crews and DIY owners the factory-level detail needed to service JCB backhoes, excavators and telehandlers correctly, whether the work involves routine upkeep or a full component rebuild. Because JCB machines combine diesel engines with complex hydraulic systems, the manuals also address hydraulic circuit diagnostics and cooling system service, giving technicians a complete reference for keeping backhoes, excavators and telehandlers working reliably on the job site. They also include step-by-step teardown and reassembly instructions, helping technicians work through repairs methodically rather than relying on guesswork.
