New 1000 Series
To fit
1 Remove the covers from the pipes, manifolds and
the turbocharger.
2 Check that the turbocharger inlets and outlets are
clean and free from restriction and that the
turbocharger shaft rotates freely. Also check that the
open ports in the manifolds and the exhaust pipe are
clean and free from restriction.
3 Fit a new gasket to the exhaust manifold to
turbocharger flange (
page 149 /A1). If the original nuts
are to be used, ensure that the threads of the studs
are clean and apply a suitable compound to the studs
to prevent seizure. The threads of new nuts are
phosphated to prevent seizure. Fit the turbocharger.
Fit the nuts and tighten them to 44 Nm (33 lbf ft) 4,5
kgf m.
4 Lubricate the bearing housing of the turbocharger
with clean engine lubricating oil. Fit the oil supply pipe
together with a new joint and tighten the flange
setscrews. If the lower section of the pipe is flexible,
clean the thread of the union connection and apply
POWERPART Threadlock (pipe). Ensure that dirt
does not enter the oil filter head/adaptor plate. Use a
spanner to hold the flats on the pipe while the union
connection is fitted to the oil filter head/adaptor plate.
If an adaptor is used in the oil filter head/adaptor
plate, use a spanner to hold the adaptor when the
union nut is tightened.
5 Fit the oil drain pipe together with a new joint and
tighten the flange setscrews, but do not connect the
hose.
6 Where the exhaust elbow has a flange, clean the
threads of the studs in the flange of the turbocharger.
Apply a suitable compound to the studs to prevent
seizure of the nuts. Put a new gasket in position on
the flange and fit the elbow. Tighten the nuts to 22 Nm
(16 lbf ft) 2,2 kgf m (plated) or 25 Nm (18 lbf ft) 2,5 kgf
m (non-plated). Fit or connect the support bracket
between the elbow and the cylinder block. Ensure that
there is no stress on the exhaust elbow. If necessary
fit the heat shield for the fuel lift pump.
7 Where the exhaust elbow (A2) has a sleeve (A1),
check that the sleeve protrusion from the end of the
elbow is 23 mm (0.90in) (A9).
8 Fit the elbow in the correct position to the support
bracket (A5) and tighten the setscrews (A4) finger
tight. Some engines have an aluminium heat shield
(A3) between the elbow and the bracket.
9 Fit the sleeve together with the elbow and bracket
into the turbocharger outlet. Fit the setscrews (A6 and
A7) which hold the bracket to the cylinder block, finger
tight. Ensure that the setscrew (A6) has a thick
washer fitted between the setscrew and the bracket.
10 Fit the gasket and connect the exhaust pipe for the
application to the exhaust elbow. Tighten the studs
(A10) to the recommended torque.
11 Fully tighten the setscrews that hold the bracket to
the elbow. Check that there is a gap of 6,5 mm (0.25
in) (A8) between the turbocharger outlet and the end
of the elbow. This gap should be equal all around the
elbow. Fully tighten the setscrews that hold the
bracket to the cylinder block.
12 Slide the hose on the induction manifold elbow
onto the compressor outlet and tighten the hose clips.
13 Check that there is no restriction in the air filter to
turbocharger hose. Fit the hose and tighten the clip.
14 Operate the stop control or, where fitted,
disconnect the electrical stop control. Operate the
starter motor until there is a flow of lubricating oil from
the oil drain pipe of the turbocharger. Connect the oil
drain pipe. Where fitted, connect the electrical stop
control.
