Vacuum Gasket Mount Adjustment
1. With the hopper in the normal position,
observe contact between the back of the
hopper and gasket. If complete seal is not
maintained, raise the high dump hopper.
WARNING
Do not rely upon the hydraulic cylinders to keep
the hopper raised for maintenance. Always
engage the safety arm before servicing the
hopper.
2. Loosen the mounting bolts in the gasket
mount. Move the assembly toward the
hopper. Tighten the bolts. Test and repeat if
necessary.
Flap Replacement
Flaps located at the entrance lip and on the
sides 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.
WARNING
Do not rely upon the hydraulic cylinders to keep
the hopper raised for maintenance. Always
engage the safety arm before servicing the
hopper.
3. Turn off the engine
4. Remove the flap retaining angle and worn or
damaged flaps.
5. Install the new flaps.
6. Replace the retaining angle.
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.
PARKING BRAKE
Normal adjustment of the parking brake can be
accomplished from the operator compartment.
Locate the knurled handle on the parking brake
lever. Turn the handle clockwise to increase
brake tension.
NOTE: Two or three turns is usually adequate.
DO NOT OVERTIGHTEN.
If this adjustment becomes ineffective, it will be
necessary to adjust the cable length.
Adjusting The Parking Brake Cable Length
1. Park the machine on a level surface and
chock the wheels.
2. Place the parking brake lever in the “OFF”
position.
3. Turn the knurled handle counter-clockwise as
far as possible.
WARNING
Do not rely upon the hydraulic cylinders to keep
the hopper raised for maintenance. Always
engage the safety arm before servicing in the
area of the hopper.
4. Raise the hopper and engage the safety arm.
5. Locate the cable clevis ends for the parking
brake cables.
6. Disconnect the clevis ends from the bar.
7. Loosen the jam nuts at the base of the clevis.
