14 CRANKSHAFT ASSEMBLY
To fit
1 Clean the crankshaft palm (14A.09/A8) and
check for wear in the seal location areas. If there is
wear, a "Speedi-Sleeve" (14A.13/A1), part number
21825188, can be fitted, see "To fit and remove a
"Speedi-Sleeve". If a "Speedi-Sleeve" is not
available the crankshaft palm can be machined to
give a minimum diameter of 133,17 mm (5.243 in).
Do not machine the last 2,5 mm (0.10 in) of the
crankshaft palm as this is necessary for flywheel
location. A "Speedi-Sleeve" must not be fitted if the
crankshaft palm has been machined undersize.
2 Ensure that the dowels for the oil seal housing
are fitted in the cylinder block. Put a new joint
(14A.09/A10) in position on the dowels, no jointing
compound is necessary.
3 Put the seal replacer tool, which is used for
standard seals, on the crankshaft palm. Lubricate
lightly the crankshaft palm, the seal replacer tool
and the lip of the seals with clean engine lubricating
oil.
4 Put the seal and housing assembly onto the seal
replacer tool and carefully push the assembly onto
the dowels. Remove the seal replacer tool, fit the
setscrews and the cap screws together with their
washers. Tighten the setscrews to 22 Nm (16 lbf ft)
2,2 kgf m and the cap screws to 13 Nm (10 lbf ft)
1,3 kgf m.
5 Fit a new "O" ring (14A.09/A6) in its recess in
the seal housing and lightly lubricate it with clean
engine oil.
6 Apply a suitable jointing compound to one side of
a new cover joint to hold the joint in position. Put
the joint in position on the flywheel housing. Put the
cover into position on the joint and fit the
setscrews. New setscrews have a sealant applied
by the manufacturer. If these setscrews are to be
used again, the threads of the setscrews and the
threads in the flywheel housing must be cleaned. A
suitable sealant, for example POWERPART
Threadlock, must then be applied to the setscrew
threads. Tighten the setscrews to 22 Nm (16 lbf ft)
2,2 kgf. m.
7 Ensure that the location faces of the flywheel
and crankshaft are clean and free from damage. Fit
the flywheel and the setscrews together with their
washers. Tighten the setscrews to 105 Nm
(77 lbf ft) 10,7 kgf m.
8 If the starter motor is removed from the engine,
clean the flange face of the starter motor and the
face of the flywheel housing. Apply a 2,0 mm
(0.080 in) continuous bead of POWERPART
Silicone rubber sealant to the flange face of the
starter motor near to the spigot before the starter
motor is fitted.
Caution: If the engine is to be operated before oil
is added to the flywheel housing, the rear oil seal
must not be fitted until after the engine has run.
