Check the Drawbar Wear Blocks
Inspect the stop wear blocks, 1, for excessive
wear. If there is wear on the blocks, rotate them
90° to provide a new wear surface for the
drawbar to ride against.
Measure the clearance between the top bridge
plate, 2, and the drawbar support, 3. If there is 3
mm (1/8″) or less clearance, replace the wear
block under the bridge plate. Support the
drawbar and remove the clevis, 4, from the top of
the drawbar. Remove the bolt, 5, and lift off the
top bridge plate. Replace the wear block and
reassemble the bridge plate. Torque the bridge
plate bolt to 952 N⋅m (702 ft. lbs.). Replace the
clevis and torque the clevismounting bolts to 952
N⋅m (702 ft. lbs.).
NOTE: The wear block under the bridge plate
is attached to the plate with four cap screws.
Be sure to reinstall the wear block cap
screws during reassembly.
