Section 1 - General Information
Introduction About this Publication This publication is designed for the benefit of JCB Distributor Service Engineers who are receiving, or have received, training by JCB Technical Training Department.
All sections are listed on the front cover; tabbed divider cards align directly with individual sections on the front cover for rapid reference.
These personnel should have a sound knowledge of workshop practice, safety procedures, and general techniques associated with the maintenance and repair of hydraulic earthmoving equipment.
Where a torque setting is given as a single figure it may be varied by plus or minus 3%. Torque figures indicated are for dry threads, hence for lubricated threads may be reduced by one third.
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 and ingress of dirt. Finally, please remember above all else SAFETY MUST COME FIRST!
'Left Hand' and 'Right Hand' are as viewed from the rear of the machine facing forwards. This Service Manual covers the following machines: JZ140
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
Routine Maintenance - includes service schedules and recommended lubricants for all the machine.
The remaining sections are alphabetically coded and deal with Dismantling, Overhaul etc. of specific components, for example: A
Attachments
B
Body & Framework...etc.
The page numbering in each alphabetically coded section is not continuous. This allows for the insertion of new items in later issues of the manual. Section contents, technical data, circuit descriptions, operation descriptions etc. are inserted at the beginning of each alphabetically coded section.

Section 1 - General Information Introduction Schematic Codes
Schematic Codes Colour Codes The following colour coding, used on illustrations to denote various conditions of oil pressure and flow, is standardised throughout JCB Service Publications.
Red
Full Pressure: Pressure generated from operation of a service. Depending on application this may be anything between neutral circuit pressure and MRV operating pressure.
Pink
Pressure: Pressure that is above neutral circuit pressure but lower than that denoted by Red.
Orange Blue Green Light Green Yellow
1-2
Servo: Oil pressure used in controlling a device (servo). Neural: Neutral circuit pressure. Exhaust: Cavitation: Oil subjected to a partial vacuum due to a drop in pressure (cavitation). Lock Up: Oil trapped within a chamber or line, preventing movement of components (lock up).

Section 1 - General Information
Torque Settings Introduction - Zinc Plated Fasteners and Dacromet Fasteners Some external fasteners on machines are assembled using an improved type of corrosion resistant finish. This type of finish is called Dacromet and replaces the original Zinc and Yellow plating used on earlier machines. Fastener Type
Colour
The two types of fasteners can be readily identified by colour and part number suffix as follows:
Part Number
Zinc and Yellow
Golden finish
‘Z’ (e.g. 1315/3712Z)
Dacromet
Mottled silver finish
‘D’ (e.g. 1315/3712D)
Note: As the Dacromet fasteners have a lower torque setting than the Zinc and Yellow fasteners, the torque figures used must be relevant to the type of fasteners. Note: A Dacromet bolt should not be used in conjunction with a Zinc and Yellow plated nut, as this could change the torque characteristics of the torque settings further. For the same reason, a Dacromet nut should not be used in conjunction with a Zinc and Yellow plated bolt. Note: All bolts used on JCB machines are high tensile and must not be replaced by bolts of a lesser tensile specification. Note: Dacromet bolts, due to their high corrosion resistance are used areas where rust could occur. Dacromet bolts are only used for external applications. They are not used in application such as gearbox and engine joint seams or internal applications.

Section 2 - Care and Safety Safety Check List Safety - Yours and Others
Safety - Yours and Others All construction and agricultural equipment can be hazardous. When a JCB machine is correctly operated and properly maintained, it is a safe machine to work with. But when it is carelessly operated or poorly maintained it can become a danger to you (the operator) and others. Do not work with the machine until you are sure that you can control it. Do not start any job until you are sure that you and those around you will be safe. If you are unsure of anything, about the machine or the job, ask someone who knows. Do not assume anything. Remember – BE CAREFUL – BE ALERT – BE SAFE GEN-1-6
As well as the warnings in the following pages, specific warnings are given throughout the book. This section is designed to give a safety code for use of the machine generally and for operation and maintenance practices. Note: This section includes a certain amount of operating safety information. But remember that whenever you drive the machine or operate its controls, you are in effect a machine operator. Therefore you should read and understand the information given in the Operator Handbook before driving the machine or operating its controls.
