face toward bearings (P) and (N). Pack cavity in wheel
hub between seal (L) and cup with grease.
26. Slip spacer (M) on roll hub (E) and against shoulder.
Hand pack cone of bearing (P) with grease and install
cone on roll hub. Now install this assembly on roll hub
(E). Fill void that will be between bearings (P) and (N)
with grease. Hand pack cone of bearing (N) with grease
and install cone on roll hub(E). Install seal (K) in wheel
hub (G). Lip of seal to face outward. Bolt bearing
retainer (H), WITHOUT SHIMS (J), to wheel hub. Now
check rolling torque of wheel hub with a torque wrench
or torque scale. Torque should be between 10 and 15 ft.
lbs. Use shims (J) as required to gain this torque. Bend

IMPORTANT: Break-in Sequence for Shaft
Run unit for 15-20 minutes at 1200 vibrations per
minute, then increase vibrations to 1700 and run for 1
hour. Stop unit. Test heat of housing (G) with a
commercial type thermometer by placing it upright on
top of the housing. Housing heat should not go beyond
2250F. If beat goes above this temperature, or vibrator
shaft slows or stops - Stop run-in procedure and allow
housings to cool completely.
