4.
With capscrews to the outside, place the sprocket and
bushing assembly on the shaft, positioning the assembly
with the bushing flange towards the shaft bearings.
Reverse mounting the “Quick Detachable” (QD)
bushing can be advantageous for some applications.
5.
Repeat Steps 1 – 4 for the other sprocket.
6.
Check that the teeth of both sprockets are pointing in the
same direction when installing Eagle NRG
sprockets.
7.
Snug the capscrews so that the sprocket/bushing
assembly can still move on the shaft.
8.
Align the sprockets using a straightedge. Check for
contact in four places as shown. Do not use bearings or
drive shafts as reference points for sprocket alignment.
Goodyear Engineered Products Laser Alignment Tool
provides an alternative method for checking alignment.
9.
Using a torque wrench, tighten the capscrews to the
torque values listed below. If there is not a gap of 1/8”
to
1
4
˝
between the bushing flange and the sprocket hub
then disassemble the parts and determine the reason for
the faulty assembly.
10. The sprocket will draw onto the bushing during
tightening. Always recheck alignment after tightening
the capscrews. If alignment has changed, return to
Step 7.
11. Tighten the setscrews over the keyway to the torque
values listed in the table to the right.
12. If the sprockets are straight bore, use the above
alignment procedure and then tighten the setscrews
to the correct torque for the setscrew size listed in the
Torque Specifications table.
QD bushings can be installed with the capscrews on either
side, excluding H, M, and N sizes. Drives with opposing shafts
require one of the sprockets be mounted with the capscrews
on the flange side and one with the capscrews on the hub side.
