3.8 Profiling the Seal Housing Tube
With the seal housing tube now firmly secured into the bulkhead
fitting, bend the tube so that it closely follows the profile of the
differential. (Figs.12.,13., & 14.)
Check that the contour of the tube will not interfere with the bearing
caps, the Air Locker, the ring gear or the axle housing. Ensure at
least 8mm (5/16”) clearance between the seal housing tube and the
Air Locker.
