plate to the crankcase, using a new gasket
(photos).
11 Fit the belt sprocket and partially tighten
its bolt. Then, using an oil filter strap wrench
or similar device to hold the sprocket against
rotation, tighten the bolt to the specified
torque. Take care not to damage the teeth of
the sprocket, which is of fibre construction
(photo).
Oil sump, sump pan and
breather
12 Fit the oil drain pipe by tapping it into
place, squarely in its hole in the crankcase.
Tighten its retaining bolt (photo).
13 Bolt up the oil pump, using a new gasket
at its mounting flange (photo).
14 Fit the sump (using a new gasket) and
tighten the securing screws to the specified
torque. Note the reinforcement washers
(photo).
15 Insert the oil pump/driveshaft into the
distributor hole. This does not have to be
specially positioned as the distributor is
splined to the shaft and can be set by moving
its location in the splines (refer to Chapter 4)
(photo).
16 Push the breather into its crankcase
recess and tighten its securing bolt (photos).
Flywheel, crankshaft sprocket
and pulley
17 Make sure that the flywheel-to-crankshaft
mounting flange surfaces are clean. Although
the bolt holes have unequal distances
between them, it is possible to fit the flywheel
in one of two alternative positions at 180º
difference. Therefore if the original flywheel is
being refitted, align the marks made before
removal.
18 If a new flywheel is being fitted, or if
alignment marks were not made before
dismantling, set No. 1 position at TDC
(crankshaft front Woodruff key pointing
vertically). Fit the flywheel to its mounting
flange so that its timing dimple is uppermost
and in alignment with the relative position of
the TDC mark on the flywheel housing
inspection window.
19 Insert the bolts and tighten them to the
specified torque, jamming the ring gear to
