6.2A SHEAR ARM ADJUSTMENT
REFER TO FIGURE 11 ON THE FOLLOWING PAGE.
Adjustment on the shear arm is maintained on the front (operator’s) side by the pressure plate (A) and
on the rear by the rub blocks (I & J). The cylinder cover shroud must be removed to gain visual access.
USE THE FOLLOWING STEPS TO ADJUST THE SHEAR ARM.
SEE FIGURE 11 ON THE FOLLOWING PAGE.
1.
Before making these adjustments, loosen the lower blade holder (C) and back the lower blade away
from the upper blade. After making these adjustments, reset the blades following the instructions in
SECTION 6.2B.
2.
Loosen the six adjusting screws (H) for each of the rub blocks (I) and remove the rub blocks by
taking out the three mounting screws (G). (If excessive concave wear is noted on the rub blocks, they
can be turned and the back surface used.) Set the pressure plate adjustment before resetting the rub
blocks.
3.
For the pressure plate adjustment, loosen the lock nuts (B) on the four adjusting screws that engage
the pressure plate (A).
4.
Tighten all four adjusting screws on the pressure plate so that they are "snug" and will force the
shear arm solidly against the rear frame. (Excessive tightening of these screws only increases wear.)
5.
Replace the rub blocks (I). With the shear arm in the down position, tighten the bottom adjusting
screws (H) until the rub blocks come in contact with the shear arm rub blocks (J). Raise the arm
about half way and adjust the middle two adjusting screws (H) until the rub blocks make contact.
Then, raise the arm completely and adjust the top two screws. (Once again, excessive tightening will
cause unnecessary wear.) Check to be sure that the rub blocks (I) are in contact with the shear arm
rub blocks (J) throughout the full stroke.
6.
Tighten the lock nuts (A) on the pressure plate adjusting screws.
7.
Reset the shear blade adjustment. SEE SECTION 6.2B.
