when they wear down to a thickness of 1/8”. Inspections should be made every month to monitor the wear.
TO REMOVE THE SKID SHOES: Open the side door/guard. Tighten the conveyor belt fully to take the
weight off of the skid shoes. Do this on each side of the machine. Loosen and remove the two ½” bolts that
hold each skid shoe to the side frame arms. Note the way that the angles/brackets of the skid shoes are
situated in relation to the side frame arms. Pry the skid shoes out toward the center of the machine.
Replace with new skid shoes and fasteners. The skid shoes should sit down flush on the side frame arms
that they fasten to. A clamp may be needed to hold the skid shoes down when refastening to ensure that
they are flat on the arms. Slightly loosen the conveyor belt until there is one-inch play midway between the
large 8” rollers.
HYDRAULIC COMPONENTS
CYLINDERS There are two single acting cylinders that trip the bucket. Hydraulic pressure from the towing
vehicle raises the cylinders and the weight of the bucket and gravity lowers them. Check for hydraulic leaks.
There are seal kits to repair leaking cylinders. A WD-40 type penetrate can be used to prevent the seals from
drying out when the machine sits for the off-season. It can also lubricate the rods when first operating a
machine after it has sat for a period of time.
TO REPLACE THE CYLINDER SEALS: Power wash or clean the cylinder before removing it from the
machine. Remove hose from the cylinder. Place the base of the cylinder in a vice and position the cylinder
horizontally. Use a bar through the piston rod hole to pull out the piston and piston rod assembly.
CYLINDER DISASSEMBLY Unscrew the top with a spanner wrench. Remove the rod/piston assembly.
Never try to slide the gland over the end of the piston rod. To clean gland, remove nut on bottom of piston
rod and disassemble from that side.
Before removing seals, wipers and o-rings, take note of their orientation in the piston and gland. When
replacing felt wipers, make sure they have been saturated in oil. Coat all surfaces in oil before reassembly.
WHEELS SPINDLES AND AXLES To check for play in the spindle/hubs, elevate the wheels off of the
ground and check for play or looseness on the spindles. It is easier to determine if adjustment is necessary
when the tire/wheel is off the hub. If there is excessive play, the bearing and races should be inspected for
damage.
TO ADJUST WHEEL HUBS: Remove the buddy hub/grease reservoir from the end of the hub. Clean away
the grease. Remove the cotter pin. Tighten the castle nut assembly until the play is gone. Reinsert the cotter
pin and grease reservoir. There is a blue collar on the grease reservoir that extends out when grease is
added. Add grease to the reservoir until the blue collar extends out. Check for tightness of the wheel cone
nuts. They should be tightened to 95 ft/lbs. Tires should be inflated to 18 PSI.
TINE REPLACEMENT Replace tines as they break. Your machine can clean effectively with 20 or 30 tines
missing; however, it is advisable to replace them soon after they break. When a tine is broken, the work it
would normally do picking up material is transferred to the adjacent tines. This will overwork them and, in
turn, shorten their life. Never operate your machine with more than 50 broken tines. Tines will shorten as
they are used and should be replaced when they wear to within ½” of the bends.
The most convenient location for removing and replacing tines on the conveyor belts is on the top of the
machine with the top shield removed.
Position the belt. Rotate the conveyor belt slowly and stop it when the row on which you are going to replace
the tines is conveniently located.
