6 If the liner protrusions are all below the specifications or low in the range, 0,025 mm (0.001 in) or 0,051 mm
(0.002 in), try a thinner spacer plate, available from your Perkins dealer. These plates are 0,076 mm (0.003 in)
thinner than the original plate and will increase the liner protrusion. Use these spacer plates to compensate for
low liner protrusions which are less than the 0,076 mm (0.003 in). Use these spacer plates if inspection of the
top face of the cylinder block reveals no measurable damage directly under the liner flanges but the average
liner protrusion is less than 0,076 mm (0.003 in).
Caution: Do not exceed the maximum liner protrusion of 0,152 mm (0.006 in). Excessive liner protrusion will
cause the liner flange to crack.
7 When the liner protrusion is correct, add a temporary mark to the liner and to the spacer plate to assist with
the assembly procedure. Remove the bolts and washers, and withdraw the cylinder liners.
8 When the engine is ready for final assembly, the 'O' ring seals, the cylinder block and the upper filler band
must be lubricated before installation. If the lower 'O' ring seals are black in colour, apply liquid soap to them
and to the cylinder block. Immerse the upper filler band in clean engine oil. If the lower 'O' rings are brown in
colour, apply engine oil to them and to the cylinder block. Immerse the upper filler band in clean engine oil.
Note: Apply liquid soap and/or clean engine oil immediately before assembly. Do not apply the liquid soap and/
or clean engine oil to the seals too early as the seals may swell and become pinched by the liners during
installation.
