Install Instructions

7. Position the bushing - product assembly axially on the shaft such that it is aligned with its
running mate. Be sure to check for adequate clearance between the assembly and other
nearby components if applicable. If the bushing has a setscrew over the keyway, tighten it to
the torque value in Table 2.
NOTICE: Tightening the set screw to a torque higher than shown in Table 2
may lead to Bushing damage or breakage. AVOID.
8. If the bushing - product assembly is not between the shaft bearings, then locating the
assembly closer to a bearing will reduce the load
and increase the life of both bearings. Check for adequate clearance
as stated in Step 7.
9. Using a torque wrench and appropriate socket, tighten the capscrews with lock washers
sequentially until each is tightened to the torque shown in Table 2. When the capscrew
torque is at or near recommended torque, make at least two more sequential rounds to
assure all capscrews are at the Table 2 capscrew torque value.
NOTICE: Tightening the cap screws to a torque higher than shown in Table 2
may lead to Bushing damage or breakage. AVOID.
10. If cap screws are provided with the product, use them instead of the ones provided with the
bushing.
11. Since tightening the capscrews may affect the axial position of the product, confirm that it is
still properly aligned with its running mate. If not, determine how much the assembly must be
moved to be in proper alignment.
12. If axial adjustment is required, (following removal procedure), reposition the assembly and
repeat step 9.
13. Check installation gap - there must be a gap between the bushing flange and the product
face. If there is no gap between them, disassemble the parts (following removal procedure)
and determine the reason(s) for the faulty assembly.

INSTALLATION
5. Align the shaft keyseat as applicable
with the bushing bore keyway and in-
stall the key. Make sure the key runs
the entire length of the bushing bore.
6. For standard Q-D mounting, align the
non-threaded holes in the product
with the threaded holes in the bush-
ing flange. For reverse Q-D mounting,
align the non-threaded holes in the
bushing flange with the threaded
holes in the product. See illustration
below. Some Q-D products can only
be reverse mounted. Insert the cap
screws and thread them by hand
three or four turns.
4. It may be necessary to slightly wedge open the saw slot on some bushings in order to start
the bore and position the bushing onto the shaft. A narrow edged regular screw driver may
be used.
NOTICE: Excessive wedging forces in Bushing saw slot may damage
or break Bushing. AVOID.
Removal:
1. Heavier product may require a hoist or other means of supporting the product during the
removal procedure. When removing from a vertical shaft, make sure the bushing and
product do not drop during removal.
2. Remove all capscrews sequentially. If the bushing has a keyway setscrew, loosen it.
3. For standard Q-D removal, insert capscrews into all threaded holes in product. For reverse
Q-D removal, insert cap screws into all threaded holes in bushing flange. In both cases,
insert the removal screws from the same side of the assembly, wherever possible, from
which the capscrews were just removed. See illustration on page 4.
