HIGHPRESSUREPUMP(H.PPump)

(Fig. 5)

HP pump draws fuel from the fuel tank through

water sedimenter and fuel filter. It supplies high

pressure fuel (upto 1600 bar) to the injectors. It

has got inlet metering valve and in-built feed

pump, Integrated pressure limiter and integrated

fuel temperature sensor. This pump is driven by

by the engine timing belt.

REMOVALANDINSTALLATIONOFHPPUMP

Removal

Disconnect the fuel lines from Fuel filter to Pump,

and plug the port.

Remove the back-leak pipes (pump to filter and

Injector to pump) and the electrical connections

on the pump.

Remove the HP line connected between pump

and rail (Ref: Engine overhaul section)

Plug the openings of rail and HP pump to avoid

dust / dirt entry.

Remove the timing belt and pump gear (Refer

engine dismantling section)

Unscrew the bolts of Pump support on the block

and mounting bracket & remove.

Remove the pump and place it in a clean area.

Installation

Fit the pump on the block with the 3 bolts at front

(on the mounting bracket) and hand tighten

initially. Similarly fit the 6 bolts at the rear mounting

bracket, then apply the torque.

Fit the gear on the pump shaft with the nut (use

special tool) and apply torque.

Remove the plugs on pump and rail just before

fitting the new set of HP pipes and assemble the

pipe connecting between HP pump and rail.

Fit all the hydraulic connectors (Back leak pipe,

fuel lines etc).

Fit the electrical connectors.

Fit the timing belt.

NOTE

Do not bend or apply any force on the HP line

while fitment.

Ensure that no fuel leakage is observed from any

where after starting the engine at idle and at

maximum speed of engine.

SEDIMENTER

(Fig. 6)

This is a part of Fuel filteration system. Fuel

sedimenter separates Water content in Diesel and to

prevent water from entering in the Fuel System. It

gives additional water volume storage. This is fitted

to the chassis long member (fig.7). A water sensor is

fitted in the sedimenter to indicate to the driver that
