Note:
Maintain a minimum 1/16” (1.6 mm) clearance between chain coupler sprockets.
Gearbox mounting procedure
for the following augers:
• 8" x 56’-61’ -71'
• All 10" augers
See Figure 3.9.
1. These augers are equipped
with chain couplers. Remove
chain and secure half the
chain coupler to the
driveshaft. Use a Woodruff
key on 8" augers and a 1/4”
x 1-1/2” square key on 10"
augers.
2. Place gearbox assembly on
auger tube. Reinstall chain leaving a 1/16” (1.6 mm) clearance between chain
coupler sprockets.
3. Secure gearbox assembly to auger tube with half tube clamps and four
7/16” x 1" bolts and locknuts.
4. After mounting gearbox assembly, adjust sprocket clearance to approximately 1/16”
(1.6 mm). Tighten set screw.
Ensure that gearbox assembly is mounted in the proper location
(Figure 3.6). Failure to properly locate gearbox will result in an
unsafe operating condition.
Add EP90 lube oil to the gearbox before operating auger. Failure to do so will void
warranty. Do not overfill. Fill half full only.
