CRANKSHAFT ASSEMBLY 14
Caution: When the sump joint is removed, damage
can occur to the seal in the grooves of the bridge
piece. If the seal is damaged, apply enough sealant
to completely fill the grooves.
Note: Most of the latest engines have setscrews in
place of studs to fasten the sump to the bridge
piece. The threads of the setscrews have a sealant
applied by the manufacturer. When the setscrews
are to be used again, ensure that the threads of the
setscrews and of the bridge piece are clean and a
sealant is applied to the threads of the setscrews.
These instructions also apply to studs.
10 Fit the connecting rod caps, operation 13A-01.
Rotate the crankshaft two turns to ensure free
movement.
11If necessary, fit the balancer unit, operation
14A-10. If a balancer unit is not used, fit the
lubricating oil pump, the lubricating oil suction pipe
and strainer, the delivery pipe and the relief valve
(four cylinder engines) and if necessary, the
lubricating oil crossover pipe, see section 19.
12Fit the rear oil seal housing, operation 14A-02A
or 14A-02B.
13 Fit the flywheel housing and the flywheel, see
section 22.
14 Fit the timing case and the timing gears, see
section 15.
15Fit the fuel injection pump, see section 20.
16Fit the timing case cover, operation 15A-01.
17 Fit the compressor and its drive assembly or fit
the exhauster, see section 24.
18 Fit the alternator and its mounting bracket, see
section 23.
19Fit the crankshaft pulley, operation 14A-01A or
14A-01B.
20 Fit the coolant pump, the fan drive pulley and
housing, the drive belts and the fan , see section
21.
21Fit the lubricating oil sump, operation 19A-03.
22 After the engine has been installed, fill the
lubricating oil sump to the correct level with an
approved oil. Fill the cooling system.
To inspect14A-09
Check the crankshaft for wear and other damage.
The maximum permissible wear and ovality on the
crankshaft journals and crank pins is 0,04 mm
(0.0016 in).
The main journals and the crank pins of standard
size crank shafts can be machined to 0,25mm
(0.010 in), 0,50mm (0.020 in) or 0,75 mm (0.030 in)
undersize on diameter, see the data and
dimensions. Special undersize bearings are
available.
If the seal has been used in all of the service
positions, the crankshaft palm can be machined to
remove the wear marks. Further information can be
found in the data and dimensions.
