3.8 Profiling the Seal Housing Tube
c Without using sharp, jagged tools such as pliers (your hands are
the best tool for this job), bend the seal housing tube so that it
closely follows the profile of the differential. (Figs.15. & 16.)
c Check that the contour of the tube will not interfere with the Air
Locker or the ring gear.
c Support the inner compression nut from rotation with a wrench
(inside the housing) and tighten the center compression nut.
