HYDRAULIC MODELS
1. Remove the covers from the hydraulic motor
mount. Remove the lower cotter pin and
clevis pin from the coupler used to attach the
hydraulic motor to the input shaft of the gear
box.
2. Remove the two 3/8"-16 x 1-1/2" carriage bolts
that hold the end bearing. Remove the four
1/2" button head bolts that hold the gear box.
Removing these fasteners will allow the gear
box assembly to drop out.
STEEL HOPPER SPREADERS – GAS & HYDRAULIC: GEAR BOX
REPLACING THE GEAR BOX
Disconnect and isolate the spark plug wire,
electrical connections, or hydraulic lines as
applicable.
NOTE: Inspect spreader for any kind of sill
damage that may affect repairs.
Loosen the Conveyor Chain
1. Locate the master link in the conveyor chain.
Rotate the chain until the master link is at the
drive sprockets.
2. Loosen the fasteners on each of the idler shaft
bearings, located at the front of spreader on
both sides of the sill.
3. Loosen the take-up bolts enough to allow the
idler shaft to slide back evenly. This will allow
the conveyor chain to slacken.
4. Remove the cotter pins from the master link on
each side. Pull each link pin out.
NOTE: There may still be some tension on the
pins due to the weight of the chain.
Removing the Clutch
See "Removing Clutch" in the
Removing & Installing Electric Clutch section of
this manual.
Installing the Gear Box Assembly
1. Install the replacement gear box by pushing it
up into place and securing it with four
1/2"-13 x 3/4" button head bolts with lock
washers. Secure the end bearing using two
3/8"-16 x 1-1/2" carriage bolts.
2. Check the position of both 6-tooth drive
sprockets for correct location on the gear box
output shaft. Adjust as needed.
3. If not already installed, install the gear case
breather.
4. Check oil level. Add oil as needed.
5. Reinstall chain.
