Boring and replacing the cylinder liner
Referring to Fig. 22, the inside diameter of the liner
should be checked at points 1, 2, and 3 and in the
directions (a) and (b). The liner on which the wear has
exceeded the service limit can be bored and honed to
0.020 in (0.50mm) oversize. The finished dimensions
are 3.012 to 3.013 in: (76.500 to 76.519mm) Models
5416 and 5424.
An oversized piston and rings must then he used with
this liner. Once this oversized liner has exceeded its
wear limit, it should be replaced with a new one. To
install a new liner, coat the outside liberally with oil,
push into the block with a press and finish to the
standard Size. When this is done, a standard size
piston must again be used.

Tightening Cylinder Head Capscrews (Fig. 23)
(1) The tightening torque of the cylinder head
capscrews is 54 to 58 ft.lbs. (7.5 to 8.0 kg.m).
Numbers 7, 8, 11 and 13 (

) are studs. The nuts on
these studs should also be tightened to this torque.
(2) All the capscrews must be tightened uniformaly. To do
this, tighten all the capscrews in the order indicated on
the diagram until they are just snug. Then tighten each
one (1) turn at a time in this same sequence until all
have been tightened to the required torque.
(3) The cylinder head capscrews should be re-tightened if
the engine has not been used for a long time. The valve
lash should also be adjusted each time the cylinder
head capscrews are retorqued. If the cylinder head
gasket has been replaced, run the engine for about 30
minutes and re-tighten the cylinder head capscrews as
described above.
