SIONS MEASUREMENT.
ASSEMBLY
Coat lip of all seals with Petamo grease (P/N 420 899
271).
2, Crankshaft Bearing
Clean crankshaft end with sand paper no. 180 and
remove all residue using pulley flange cleaner (P/N
413 711 809).
Smear anti-seize lubricant (P/N 413 701 000) on part
of crankshaft where bearing fits.
Heat up the bearing(s) using bearing heater (P/N 529
035 969). This will expand bearings and ease instal-
lation. If required, put a suitable plate or shim to avoid
the direct contact between integrated seal and the
heating surface.
CAUTION: Bearing should not be heated to more
than 80°C (176°F). Do not heat bearing with direct
flame or heat gun or heated oil. Inappropriate
heating procedure(s) may cause inner seal failure.
Turn bearing(s) several times during heating pro-
cess for heating it/them properly.
NOTE: Normally it takes approximately 10 minutes
to heat up a bearing. So, in the event of replacing a
bearing, it is recommended to start heating it prior to
removal. Two bearings can be heated at the same
time on one bearing heater.
