Tilt Link Arm Stop:
Some Machete models may exhibit interference between the head tilt cylinder and the cutter
motor support plate. This can result in a bent head tilt cylinder rod, a damaged cylinder gland cap, or
a damaged cutter motor housing.
In order to avoid possible damage, a stop should be fabricated and installed which will limit the
head tilt retraction before interference occurs.
A stop made from 1/2" X 2-1/4" HRFB X 6-1/2" long should be welded to head tilt link arm
weldment as shown in figure 1. This will require welding and painting.
To locate the proper angle position of the new stop, carefully retract the head until the cutter
motor support plate and the head tilt cylinder has a clearance of 1". Use caution, do not damage cylinder
when retracting the head. Place the new stop plate in the head tilt link weldment and lay it flat on the
dipper arm. Mark this position, and weld the stop in place as shown in Figure 1. It is important that the
stop is installed so that it flatly contacts the dipper when retracted in order to avoid point loading on the
boom. Extend and retract the cylinder to ensure proper installation.
