HOPPER
Flap Replacement
Flaps located at the entrance lip of the hopper must be
replaced when worn or damaged. The flap panels may
be replaced separately.
1. Park the machine on a level surface and
engage the parking brake.
2. Raise the hopper.
3. Turn off the engine
4. Remove the flap retaining angle and worn or
damaged flaps.
5. Install new flaps.
6. Replace the retaining angle.
Floor Clearance
In order to perform properly, the hopper (on both
the low and high dump models) must maintain a
distance of 3½” (8.89 cm) from the floor to the rear
hopper entrance lip. The front of the hopper should
be adjusted so that the front bumper aligns with the
hopper frame where the two meet. When properly
adjusted, the front edge of the hopper will be 5”
(12.7 cm) to 6” (15.24 cm) from the floor.
Frame Seal Replacement
Front Frame Seal
The hopper frame seal bolts to the front edge of the
engine pan. Install a new seal by folding it in half to
align the holes. Doubled edge with holes goes on the
bottom. Support the seal straight up while bolting the
retainer bar in place. The seal should fall over the
retainer bar after installation. Be certain that the seal
edges are aligned to prevent twisting of the seal.
Side Frame Seal
The side frame seals should clear the floor by at least
⅛” (3.18 cm). If the bottom of a side seal measures
½” (1.27 cm) or more above the floor, readjust it or
replace it by removing the bolts on the inside of the
wheel wells, installing a new seal, and securing it with
the bolts. The double edge with the holes goes toward
the front.
