3.7 Profiling the Seal Housing Tube
IMPORTANT:
In order for the seal housing to float and self center on the
bearing journal after the tube is connected to the bulkhead
fitting, the seal housing tube must not be left pulling against
the seal housing. Therefore, it is critical to ensure that the
tube is not under any tension. To avoid this always leave
the tube long enough so that a loose hook shape can be
formed between the seal housing and the bulkhead.
Without using sharp, jagged tools such as pliers (usually your
hands are the best tool for this job), gently bend the seal housing
tube so that it runs closely around the outside of the differential
carrier and ring gear and through the bulkhead port hole as shown
in Figure 12.
NOTE : It is also a good idea to keep the tube away from the
bearing caps or any other part of the differential
casting as any contact due to vibration or shock may
wear the tube and eventually cause a leak.
