Figure 2.4.2 Glow Plug Locations
A - LPW and LPWST4 400 Series Builds
B - All Other 300 Series Builds
On all LPWS engines, other than 400 series builds,
the plugs are fitted into the side of the cylinder head
as shown at 'B' in Figure 2.4.2.
On all 400 series builds, the plugs are fitted into the
top of the cylinder head between the injector and
cylinder head cover, as shown at 'A' in Figure 2.4.2.
fitting glow Plugs to 400 series Builds
1. Fit the glow plug (B) into the adaptor (A) and
torque it to 15.0Nm (11.0lbfft).
Figure 2.4.3 Glow Plug - 400 Series Builds
2. Screw the plug and adaptor assembly into the
cylinder head and torque it to 27.0Nm (20.0lbf ft).
3. Fit the electrical feed cable.
2.5 tHe turBoCHArger - LPw(s)t4
The turbocharger bearing is fed by a pressurised
oil feed from the crankcase oil gallery to the top of
the turbocharger.
A non-pressurised return to the crankcase door
allows the oil to drain back to the sump.
CAution
Serious damage to the turbocharger bearing can
result if or any reason the turbocharger housing
is not full of oil.
It is recommended that these engines run on 'no
load' after starting for 30 seconds, to ensure an
adequate oil supply to the turbocharger, and 30
seconds before stopping to allow the heat from the
bearing to dissipate.
2.5.1 removing the turbocharger
1. Disconnect and remove the turbocharger oil feed
pipe (A) and oil return pipe (B).
2. Remove the air cleaner, exhaust silencer and
associated parts.
3. Support the turbocharger and remove the three
mounting stud nuts (C).
4. The turbocharger can be dismantled by removing
the four nut (D).
note:
if the turbo is dismantled it must be sent back
to garrett to be balanced.

2.5.2 Refitting the Turbocharger
1. If the turbocharger was dismantled fit a new joint
(E) and assemble the unit.
It may be an advantage to replace the three nuts
and studs to aid removal at a later date.
2. Fit a new joint (F) and replace the oil feed and
return pipes.
3. Before attempting to start the engine for the first
time read the 'Caution' in "2.5 The Turbocharger
- LPW(S)T4".
2.6 tHe CrAnkCAse BreAtHer
The breather canister and hoses should be checked
periodically, and cleaned if there is evidence of
frothy, emulsified oil blocking the passageways.
This should be done at least every 500 hours; more
often in cold climates, or if the engine is started and
stopped frequently without being allowed to reach
normal operating temperature.
Blow-by vapours are routed to the canister through
a hose connected to the cylinder head cover. Any
entrained lubricating oil mist is separated in the
canister and allowed to drain back to the sump
