O-Rings - New Holland TI4.70 RS Service Manual

1.6.1.3 Replacement
When servicing an assembly, replace all seal
rings on rotating shafts and all gaskets in general.
Make sure that the seal lip of the new ring does
not run against the same surface on the shaft as
the previous ring.

1.6.2 O-Rings

1.6.2.1 Assembly
1 - Do not force O-rings over sharp edges,
threads or splines. In cases where, due to
construction constraints, this cannot be
avoided, use a conical installation bush or an
equivalent solution.
2 - Before fitting an O-ring, check that it is the
correct type specified for the application.
Clean the seat of the O-ring very carefully.
Any remaining contaminants could damage
both the O-ring and the sliding surfaces.
3 - To facilitate installation and ensure effective
lubrication immediately after fitting, immerse
the O-ring in the same type of oil with which
it will be in contact, or apply a light film of
grease compatible with the material from
which the O-ring itself is made.
4 - Take care not to twist the O-ring when
installing in its seat.
5 - Take care not to damage the O-ring when
assembling components.
