18.15 Engine Finish / Paint
Engines leave the JCB factory with a protective clear lacquer, which is sufficient in most applications
where the engine is protected by a hood or cover. Further paint processes are not preferred as a
deviation from JCB’s validated procedures. If it is determined that paint is a firm requirement of the
end user the following should be considered when defining the paint process:
Electrostatic paint spraying – the high voltages involved can cause damage to engine
electronic components. As a minimum the engine must be properly grounded (earthed).
In all cases care must be taken to ensure that correct masking procedures are in place to
protect key engine components. This includes, for example electrics, belts, pulley grooves,
labels etc.
Paint on plastic components is likely to suffer cracking due to their flexibility.
Lifting points should be masked or the lifting eyes left fitted as paint will impact the integrity of
a safety critical joint.

18.16 Engine First Start
The following points are considered key to avoiding early life problems when starting a new engine in
a machine.
Fuel systems fill and filter venting
The new machine should be filled with enough fuel to ensure that the machine can reach the dealers
site without risk of running out of fuel, including an allowance for system fill. This should include all
filters and lines as specified for the engine, including territory considerations.
Common rail engines: At initial key-on, the fuel pump will run for a period of time. During this time the
outlet manual vent should be kept open until the air has purged from the system.
Mechanical Engines: Air must be bled from the system prior to cranking to avoid damage to fuel
injection equipment.
Oil priming
Standard engines may be cranked and started normally on the starter but should be idled for the first
fifteen to thirty seconds before the engine is loaded (machine is moved).
For engines with remote oil filter, the same procedure should be followed as above but the engine
should be cranked as follows:
Crank for 10 seconds.
Wait 30 seconds (allow starter to cool).
Crank for a further 10 seconds or until oil light extinguishes.
Connect ESOS or enable fuel injection and start engine.
In all cases, the oil pressure light should be monitored; this will go out within 5 seconds of engine
achieving steady idle, and should be cause for further investigation if it does not.
NOTE: Under no circumstances should oil be poured into a new filter; it is likely that dirty oil will fall
into the clean side of the filter. This will increase opportunity for engine damage and risk early life
failures.
18.17 Machine Hot Test
Prior to hot test the following steps should be completed and noted. The machine assembly process
should maintain records of any actions required to remedy issues at this stage.
Overview of installation; check for damage to any components of engine or machine that could
cause a warranty issue
Battery terminals tight and correct batteries installed
Coolant level topped up to maximum cold level.
