FIGURE 7-7 – TIGHTEN SETSCREWS
55. Apply loctite 243 to 6 set screws (57) {M6 x 12mm}. Install 3 of these screws into each of the 2 gear locking
assemblies. These set screws go between the existing screws in the locking assembly through the
unthreaded holes in the outer ring into the threaded holes in the inner ring. The purpose of these set screws
is to keep pressure on the spacer that is between the gear and bearing inner race. Tighten the screws to 25
in-lb of torque. See
FIGURE 7-7
.
FIGURE 7-8 – MEASURE GEAR BACKLASH
56. Lock the idler rotor from turning by wedging a shop rag between the tip of a lobe and the air cylinder.
Measure the backlash of the gears using a dial indicator and a magnetic base. Gear backlash is the distance
(in the circumferential direction) a gear tooth can freely move when the mating gear is fixed. This should be
measured in 3 places (every 1/3 turn) and recorded. Verify that the backlash is within the range specified on
the clearance drawing. See FIGURE 7-8.
57. Use a feeler gauge to verify that there is at least .010
“ clearance between the heads of the 4 bearing retaining
bolts (10) and the inside surface of the gears.
58. Attach an oil slingers (26) with bolts (8) and washers (6) to the gear end of the appropriate rotor shaft.
Tighten the bolt to 132 in-lbs.
59. Install a spacer (49) onto both rotor shafts on the drive end.
