1. Strip engine. 12.41.05.
2. Measure bores for taper, ovality and maximum
wear.
3. Rebore to dimensions in Data.
NOTE: Maximum rebore size is +0*020 in. Cylin­
ders that cannot be rebored within this limit may.
be sleeved to restore them to the original size as
follows:
a . 1300 and 1500 engines bore out cylinders to
3*0302 to 3*0272 in dia.
b. Remove sharp edges from top face of cylinder
block. -
c . Lightly oil liner—DO NOT GREASE.
d. Insert the liner into the bore so that the con­
necting rod cut-aways line up with the corres­
ponding slots at the bottom of the bores (1500
engine oj$$).
e . Press§|he liner into the cylinder bore with 3 to
4 tonrm axim um pressure until flush with top
face of cylinder block.
NQTE: When pressing liners in with a screw-
typefpress there is a tendency for it to ‘creep-’
slightly in the same direction as the rotation of
the press. It is therefore necessary to set the
liner back about ^ in (0*7937 mm) when lining-
up the liner prior to pressing home.
