Do’s
• Monitor battery voltage continuously –
recharge battery if voltage drops below 10
Volts
• Drain water from Sedimenter / filter at regular
intervals
• Fix the rubber cover to the ECU to prevent
dust / moisture entry inside ECU.
• EMS W/H to be properly routed as specified
using clamps / clips and brackets.
• Do check for any faults /malfunctioning in the
sys-tem using diagnostics tool before
cranking the engine (after any repair).
• Do fix ECU connector branch properly while
transporting engine.
• If engine does not start check the respective
fuses related to CR components.
• When Injectors are replaced/Changed Injector
IC values (IMA code) must be loaded
correctly as per cylinder order.
• Plug the port of Common rail system
components whenever any pipe connections
are removed.
• Tighten the mounting nuts / cap nuts etc. only
to the specified torque values.
• Always remove the Injectors before
dismantling the cylinder head. This is to avoid
damage to the injector nozzle tips which
protrude out of cylinder head. In case of HP
pump removal handle the pump with proper
care to avoid any damage to inlet pipe, venturi
and connectors.
Characteristics of the workplace
All interventions on the injection system must be
carried out in a clean workshop. This means that
the workshop
• Must be regularly cleaned to prevent the
accumulation of dust.
• Must not contain machine tools and welding
equipment which may be capable of
generating swaf or metallic or other particles.
Entry into a dedicated repair workshop
:
• Room closed without air movement with clean
surfaces from floor to ceiling.
• Clean, smooth workbench or equivalent
(stainless steel type, no wood, cardboard or
paint).
• No eating or smoking.
General remarks
The operators working clothes must be clean.
This means that they must not carry dust or metal
particles liable to contaminate the injection and
must be manufactured from lint free, non flocking
material to avoid contamination of the injection
system by fibres.
Safety recommendations
• any intervention on the system
• As a fuel spray can lead to heavy wounds, it
is highly recommended : not to intervene on
the system with engine running
• Any intervention on the system must be
achieved by qualified and trained agent.
• Never start the engine if battery is not well
reconnected.
• Do not use the ECU metal box as a Ground.
• Disconnect the ECU when using an arc
welding station.
