Machine Model and Serial Number
This manual provides information for the following
model(s) in the JCB machine range:
– Skid Steer Loader - 135, 155, 175, 190, 205, 150T,
190T, 205T from serial number 1755000.
Using the Service Manual
T11-004
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
hydraulic earthmoving equipment.
The illustrations in this publication are for guidance only.
Where the machines differ, the text and/or the illustration
will specify.
General warnings in Section 2 are repeated throughout the
manual, as well as specific warnings. Read all safety
statements regularly, so you do not forget them.
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.
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.
The manufacturer's policy is one of continuous
improvement. The right to change the specification of the
machine without notice is reserved. No responsibility will
be accepted for discrepancies which may occur between
specifications of the machine and the descriptions
contained in this publication.
Finally, please remember above all else safety must come
first!
Section Numbering
T11-005

Machine Description
The JCB Skid Steer Loader
P12-1004
The Skid Steer Loader is a self propelled skid steer
machine fitted with either wheels or tracks. The main
structural support is designed to carry a front mounted
carriage onto which a shovel or an approved attachment
can be fitted.
Note: The illustration(s) show a typical machine model;
your machine may look different from the model shown.
Intended Use
The machine is intended to be used under normal
conditions for the applications described in this manual. If
the machine is used for other purposes or in dangerous
environments, for example in a flammable atmosphere or
in areas with dust containing asbestos, special safety
regulations must be followed and the machine must be
equipped for use in these environments.
When used normally with a shovel fitted, the machine
loads or excavates through forward motion of the machine
and lifts, transports and discharges material.
This machine is not intended for object handling.

Identifying Your Machine
Machine Identification Plate
Your machine has an identification plate mounted as
shown. The serial numbers of the machine and its major
units are stamped on the plate.
Note: The machine model and build specification is
indicated by the PIN. Refer to Typical Product
Identification Number (PIN).
The serial number of each major unit is also stamped on
the unit itself. If a major unit is replaced by a new one, the
serial number on the identification plate will be wrong.
Either stamp the new number of the unit on the
identification plate, or simply stamp out the old number.
This will prevent the wrong unit number being quoted when
replacement parts are ordered.
The machine and engine serial numbers can help identify
exactly the type of equipment you have.

The serial number is also permanently stamped into the
chassis at position A.
Typical Product Identification Number
The Product Identification Number (PIN), weight, engine
power, year of manufacture and serial number of the
machine are stamped on the identification plate.

ROPS and FOPS
!MWARNING
You could be killed or seriously injured if you operate
a machine with a damaged or missing ROPS/FOPS. If
the Roll Over Protection Structure (ROPS)/Falling
Objects Protection Structure (FOPS) has been in an
accident, do not use the machine until the structure
has been renewed. Modifications and repairs that are
not approved by the manufacturer may be dangerous
and will invalidate the ROPS/FOPS certification.
INT-2-1-9_6
!MWARNING
Seat Belts
The ROPS/FOPS is designed to give you protection in
an accident. If you do not wear your seat belt, you
could be thrown out of the machine and crushed. You
must wear a seat belt when using the machine. Fasten
the seat belt before starting the engine.
0153
Machines built to ROPS standards have an identification
label fitted inside cab, below the operator seat.
A bolt on falling object guard is available which also carries
a certified label fitted to the guard. K FOPS Data
Plate ( T 1-7).

FOPS Data Plate
!MWARNING
Do not use the machine if the falling objects protection
level provided by the structure is not sufficient for the
application. Falling objects can cause serious injury.
8-2-8-17
If the machine is used in any application where there is a
risk of falling objects then a falling-objects protective
structure (FOPS) must be installed. For further information
contact your JCB Dealer
The falling objects protection structure (FOPS) is fitted with
a dataplate. The dataplate indicates what level protection
the structure provides.
There are two levels of FOPS:
– Level I Impact Protection - impact strength for
protection from small falling objects (e.g. bricks, small
concrete blocks, hand tools) encountered in
operations such as highway maintenance,
landscaping and other construction site services.
– Level II Impact Protection - impact strength for
protection from heavy falling objects (e.g. trees,
rocks) for machines involved in site clearing,
overhead demolition or forestry.

Zinc Plated Fasteners and Dacromet Fasteners
T11-002
Introduction
Some external fasteners on JCB machines are
manufactured 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.
The two types of fasteners can be readily identified by
colour and part number suffix. K Table 1. Fastener Types
( T 1-9).
Table 1. Fastener Types
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 fastener.
Note: A Dacromet bolt should not be used in conjunction
with a Zinc or Yellow plated nut, as this could change the
torque characteristics of the torque setting further. For the
same reason, a Dacromet nut should not be used with a
Zinc or 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 in areas where rust could occur.
Dacromet bolts are only used for external applications.
They are not used in applications such as gearbox or
engine joint seams or internal applications.
Bolts and Screws
Use the following torque setting tables only where no
torque setting is specified in the text.
Note: Dacromet fasteners are lubricated as part of the
plating process, do not lubricate.
Torque settings are given for the following conditions:
Condition 1
– Un-lubricated fasteners
– Zinc fasteners
– Yellow plated fasteners
Condition 2
– Zinc flake (Dacromet) fasteners
– Lubricated zinc and yellow plated fasteners
– Where there is a natural lubrication. For example,
cast iron components
Verbus Ripp Bolts
Fig 1.
Torque settings for these bolts are determined by the
application. Refer to the relevant procedure for the
required settings.
