Section 1 - General Information 1-1 1-1 9806/3000-05 Introduction About this Manual Using the Service Manual This publication is designed for the benefit of JCB Distributor Service Engineers who are receiving, or have received, training by JCB Technical Training Department. These personnel should have a sound knowledge of workshop practice, safety procedures, and general techniques associated with the maintenance and repair of engines. Renewal of oil seals, gaskets, etc., and any component showing obvious signs of wear or damage is expected as a matter of course. It is expected that components will be cleaned and lubricated where appropriate, and that any opened hose or pipe connections will be blanked to prevent excessive loss of hydraulic fluid, engine oil and ingress of dirt. Finally, please remember above all else SAFETY MUST COME FIRST! The manufacturer's policy is one of continuous improvement. The right to change the specification of the engine without notice is reserved. No responsibility will be accepted for discrepancies which may occur between the specifications of the engine and the descriptions contained in this publication. Section Numbering The manual is compiled in sections, the first three are numbered and contain information as follows: 1 General Information includes torque settings and service tools. 2 Care & Safety includes warnings and cautions pertinent to aspects of workshop procedures etc. 3 Maintenance includes service schedules and recommended lubricants. The remaining sections deal with Descriptions, Fault Finding, Dismantling, Overhaul etc. of specific components, for example: 4 Systems Descriptions 5 Fault Finding ...etc. Left Side, Right Side References to the `left' side and the `right' side of the engine are when viewed from the flywheel end of the engine, as shown at 1A. Fig 1. Units of Measurement In this manual, the S.I. system of units is used. For example, liquid capacities are given in litres. The imperial units follow in parenthesis () e.g. 28 litres (6 UK gal). A
