3.12. Optional Low Profile Hopper Assembly
Note
The gearbox has been filled at the factory (half full) with EP90 gear oil. Before further assembly, check
oil level to make certain the gearbox is half full as required. Add oil if necessary. Do not use grease.
1. Attach the pivot-connector to appropriate 10" holes in hopper with two 5/8" x 1-1/2" bolts and locknuts
(see
). DO NOT OVERTIGHTEN, tighten snug only as these bolts act as pivot points.
2. Loosely secure the service door with the two square latch-washers and 3/8" locknuts.
Note
These must be tightened securely after hopper assembly is completed.
3. Clean dirt and paint from inside u-joint and flight shaft end, then insert Woodruff key.
4. Raise and support hopper tube at about 50" under spout. Open service door on hopper, then bring tube and
hopper together guiding flight shaft into u-joint (see
5. Secure tube to pivot-connector on hopper with 7/16" x 1" bolts and locknuts.
6. Tighten setscrews on u-joints, then close and secure the service door.
7. Attach the rubber extension to inside of hopper lip with 5/16" x 3/4" bolts and washer locknuts and flat iron
straps provided (see
).
Note
To attach the rubber extension to end of hopper, remove the two 5/16" washer locknuts that secure
the chain drive shield.
8. Attach the four pneumatic wheels to the four hopper corners with the axle pins and hairpins. The offset
portion of the wheel must rest against the hopper. You have a choice of three height settings (see
).
9. To connect the intake hopper to the auger boot, the safety discharge door must be opened. This door is
held in place internally with two springs. To open, pull the door down and then up and over the gearbox
enclosure. Hold open with C-clamp vise grip.
10. Place wide rim 1-1/4" washer shield over splined shaft on lower gear box. Check that the u-joint spline and
splined shaft on lower gear box are clean, then apply a light film of grease on this splined shaft.
11. As the intake hopper is lowered onto the boot, the splined universal joint must be guided onto the splined
shaft. Once positioned, swivel ring should be resting flat on the boot surface and inside the four spacer nuts.
12. Install four large washers with 3/8" x 3/4" bolts to keep the intake hopper in place on the boot (see
).
13. Lubricate the universal joint and then close the safety discharge door.
KEEP IT CLOSED DURING OPERATION.
