41. Secure the camshaft gear wheel in position. Install the eccentric pressed steel ring with the flange on the side,
i.e., away from the camshaft gear wheel. Torque to 22 lb-ft (30 Nm). Install hand crank adapter plate and hand
crank flange.
NOTE
Radial runout cannot be adjusted.
42. Drive the counterbolt into the camshaft gear wheel so that the distance between its end face and the joint face is
equal to the dimension determined at 45° plus 0.039 to 0.079inch (1 to 2 mm).
43. Fit a new gasket, coated with grease so that it stays in position, to the front cover plate of the camshaft and
mount the hand crank flange.
44.
Check the end clearance of the camshaft.
45.
This end clearance must be within the limits stated in the specifications. If it is on the low side, correct by driving
the camshaft gear wheel in the direction of the near end cover plate. If it is on the high side, dismantle the
camshaft gear wheel and drive the counterbolt outwards by the corresponding amount.
46. Install a new gasket and seal to the front cover; coat the gasket with grease so that it sticks in position and mount
the front cover with the oil pump to the engine (figure 5-36).
NOTE
Check the race of the oil seal. If the shaft exhibits a groove, reposition the packing ring in the front
cover.
47.
Clean the top camshaft cover and install it onto the cylinder head surface. Install a new gasket and coat it with
grease to hold it in place.
48.
Assemble the front and middle screws to align the pressed steel bottom plate in position. The treaded sleeve
must be assembled to the middle screw (figure 5-37).
49.
Install the flange mounting plate on the flywheel end.
NOTE
Place a piece of wood or other material under the flywheel end of the crankcase so that the foot on
the flange mounting plate stands clear of the bench.
