3.8. Standard Intake 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. Remove access covers, then clean paint and dirt from flight shaft end. Insert Woodruff key into flight shaft
end as shown in
2. Raise hopper tube to correct angle (22.5°), then bring hopper and tube section together, carefully sliding the
flightshaft end with Woodruff key into the angle drive. Connect the hopper and tube section with eight,
7/16" x 1" bolts and locknuts.
Important
To prevent damage, you must maintain correct angle when inserting flight shaft end into angle drive
until tube is secured to the hopper section. Allowing tube or hopper to drop will bend the flight
shaft end causing it to bind in the angle drive.
3. Thoroughly lubricate the angle drive, then replace access doors. Keep angle drive well lubricated. Use high
temperature grease.
Note
After connecting the hopper and tube sections, check whether the angle drive is properly aligned.
You should be able to rotate the hopper flight by hand if the angle drive is aligned. If it appears not
to be aligned, see maintenance section for correct procedure. The angle drive will require a break-in
period of at least 2 to 3 loads.
4. Clean wheel axles on hopper bottom of any paint and dirt.
5. Install the two wheels to hopper bottom with a washer and cotter pin each (see
).
6. Install rubber extension on inside hopper lip with twenty 5/16" x 3/4" bolts and washer locknuts, eight long
and two short flat iron straps with bow facing inward.
