These augers are equipped with chain couplers pre-installed on gearbox.
1. Remove chain and secure half the chain coupler to driveshaft using a 3/8” x
1-3/4” long square key.
2. Place gearbox assembly on auger tube leaving a minimum 1/8” (3.2 mm)
clearance between chain connectors.
3. Re-install chain and adjust sprocket clearance to approximately 1/16” (1.6
mm). Tighten set screw (Figure 3.7).
Important: Add EP90 lube oil the gearbox before operating auger. Failure to do so will void
