When assembling new or old bearing shells to caps,
tighten the retaining screws just snugly to allow self-centering
of shell on screw. Make sure that screw heads are below
the babbitt surface.
Shells are punch marked on the edge to facilitate correct
reassembly.
NOTE: Shells should fit flush with parting face of case,
but should project .002 beyond parting face of caps to
provide a slight "pinch" for correct seating.
Before bolting front and rear caps and shell assemblies into
case for reaming, and always at final assembly, they should
be centralized on studs for proper bearing alignment. This
can be easily accomplished by inserting a 1/4" drill rod in
the vertical packing holes before tightening bearing cap bolts.
At final assembly after the cap and shell assemblies have
been bolted in place with 70-80 pounds tightening torque,
the palnuts must be Installed and the packing inserted in
front and rear bearing caps as follows:
Install palnut with smooth face next to nut and spin onto
stud until it just contacts the nut. Tighten palnut 1/4 to 1/3
of a turn further for final locking.
bearing cap. Insertion of packing is greatly facilitated by
using tool J-392, Figure 19.
