See Figure 3.6.
The driveshaft segments are factory installed,
ready for connecting to the gearbox.
1. Clean dirt and paint from driveshaft ends,
inside couplers, and PTO driveline yoke.
2. Remove chain from chain coupler on gearbox,
then attach chain coupler sprocket to
driveshaft with a 1/4" x 1-1/2" square key.
Tighten set screws.
3. Place gearbox assembly on auger tube, then
reinstall chain-to-chain coupler leaving
minimum of 1/16" (1.6 mm) between coupler
sprockets.
4. Secure gearbox assembly to auger tube with
two halfbands and four 7/16" x 1-1/4" bolts and
locknuts. Tighten securely.
Important: Fill gearbox half full only with EP90 lube oil before operating auger. Do not over
fill. Failure to heed will void warranty. It is easier to fill oil into gearbox when in flat
position.
5. Attach the chain coupler guard to gearbox base with two 3/8" x 3/4" bolts and
washer locknuts (Figure 3.6).
6. Slide non-spline end of PTO driveline onto input shaft on gearbox using a

1/4" x 1-1/2" square key. Tighten set screws securely.
Note: The PTO driveline is non-separable. Do not extend beyond 80".
7. Install the PTO driveline transport saddle to auger tube about 3’ above
gearbox. Secure with two 7/16” x 1-1/4" bolts and locknuts.
8. Attach the drive shield to the shield mount with two 3/8" x 3/4" bolts and
washer locknuts, then slide this assembly over PTO driveline and attach to
gearbox with two 1/2” x 1" bolts and lockwashers (Figure 3.6).
