Using Service Tool ET.2003 as shownin Fig. C24,
extract the crankshaft pinion. It should be noted
that the jaws of the service tool locate to the
spaces provided in the pinion backing washer.

|
13
|
Lift away the pinion key which is of the
Woodruff type. Remove also the backing washer.
|
|
14
|
Remove the oil sealing disc which is lipped.
This disc tends to cling to the main bearing due to
thepresence of oil and the use of two small magnets
or some other means is recommended to lift the disc
clear.
|
|
15
|
If desired, the timing chain tensioner, clamping
plates, nuts and fan disc washers can be removed
from the crankcase at this stage.
|
|
16
|
Dismount the crankcases from the vice so that
they may be parted and the crankshaft assembly
extracted.
|
|
17
|
Remove the crankcase breather pipe complete with
elbow by slackening the locking nut at the
crankcase. On models after engine number 200000
remove the breather and breather pipe as an
assembly, after removing the locking wire, or
flattening the tab washer and taking out the two
securing bolts.
|
|
|
|
18
|
Remove the two studs, one bolt and two set
screws, holding the crankcases together. Unless the
additional bottom stud has been removed to mount
the crankcases in a vice, the stud should be
removed at this stage.
|
|

|
Part the crankcases, releasing the crankcase
joint by the use of bar of wood against the drive
side crankcase as shown in Fig. C25.

As the drive side crankcase is lifted clear,
collect the rotary breather disc and spring from
inside the drive side camshaft bush.
|
|
21
|
Withdraw the camshaft from the timing side
crankcase and on engine numbers before 200000
collect the detachable chamfered thrust washer. On
the later engines there are 2 thrust washers with
tabs engaging to holes in the crankcase. Collect
these and ensure that they are properly located on
reassembly.

|
Part the timing side crankcase from the
crankshaft. This practice is preferred to removal
of the crankshaft from the crankcase. Removal is
accomplished without striking the end of the
crankshaft by the use of a tubular drift driven
against the crankshaft shoulder. Fig. C26
illustrates a suitable tube fitted over the
crankshaft, the tube
