8 Lower the hydraulic press (B2) until it contacts the top of the stepped adaptor (B3). Press in the liner slowly,
until the stepped adaptor contacts the face of the cylinder block and the top of the liner is level with the face of
the block.
9 Assemble the liner height gauge, Part numbers, 21825496, (C3) and 21825617, (C4). Put the gauge onto
the face of the cylinder block (C2) and set the dial to zero.
Caution: The liner height must be measured immediately, before the loctite 640 has time to set; the loctite will
set fully set in 15 minutes.
10 Place the point of the liner height gauge on the top edge of the liner (C1) and measure the liner height at
four points 90° apart (C5). The reading should be within 0,075 mm (0.003 in) below to 0,05 mm (0.002 in)
above the face of the cylinder block. If the liner height is too high, the liner may be pressed in further if the
loctite 640 has not set.
Caution: Specialist training and equipment is needed to machine the finish of a partially finished liner. For
further information contact your nearest Perkins Distributor.
Partially finished cylinder liners must be bored and then diamond honed, silicon carbide base honed and silicon
carbide plateau honed to the finished size to conform to the dimensions given in "Cylinder liner specifications"
on page 22. Machine a 16° chamfer (B1) from the top inner diameter of the liner to a depth of 1,20 mm
(0.047 in). after the bore has been machined.
