2009 DURATECH TUB GRINDER OPERATING INSTRUCTIONS
A. V-ring Seal
Slide one of the V‑ring seals onto the shaft, making sure the lip is toward the bearing. Set aside until step 11.
NOTE: Do not install the V‑ring seal on the seal until the housing cap has been set in place and
tightened.
B. Seal Ring
Install a seal ring on the shaft with the largest OD toward bearing.
C. Adapter
Slide the adapter onto the shaft, with the threaded end outboard, to the approximate location of the bearing. Apply a
light coating of oil to sleeve OD. Do not use grease.
D. Bearing
Make sure that the roller clearance has been written down. Install the bearing on the adapter sleeve with the large end
of the tapered bore rst. Locate the bearing in the proper position on the shaft. Before tightening refer to Figure on the
previous page
E. Lockwasher and Locknut
Install the lockwasher on the adapter with the inner prong located in the slot and facing toward the bearing. Install the
locknut, with the chamfered face toward the bearing. Tighten the locknut using a spanner wrench and hammer until the
clearance noted in step 2 is reduced by 0.0018 to 0.0025 inch. During this step, the shafts should be supported, so that
all weight is off of the bearing. Find a lockwasher tab that aligns with a locknut slot and bend the tab into the slot. If
the slot is past the tab then tighten the locknut to meet a washer tab.
F. Seal Ring
Install a second seal ring with the large OD toward locknut.
G. V-Ring Seal
Slide the second V‑ring onto the shaft, again making certain that the lip is toward bearing.
NOTE: Do not install V‑ring seal on seal ring until housing has been set in place and tightened. See
Step 11.
4. Remove any paint, dirt or burrs from the mating surfaces of the housing halves. Thoroughly clean the
seal groves on both sides. Set the lower half of housing on the base with all four cap bolts in place, and
apply oil to the bearing seats. Apply grease to the seal grooves in the lower housing.
Be sure the housing is positioned as shown in Figure on facing page view relative to adapter nut.
