LEVATOR
The recommended speed of the wheel elevator is 11
rpm. In some conditions a slower speed of 9 to 10 rpm
may be desirable. Adjust the flow control to control the
wheel elevator speed.
Wheel drive chain to hydraulic motor.
Figure 71 - Wheel Elevator Sprocket, Chain Drive,
and Roller
To tighten the wheel elevator drive chain, see Figure 71.
Loosen nuts (A) directly below the idler. Reposition until
the chain can be pulled 1.25 inch away from the wheel
(as shown in Figure 69). The spring length directly
below these nuts is factory set to 6-3/4 long (nuts below
spring). It should not deviate from this.
The hydraulic motor mounting can be adjusted forward
and aft if needed. Adjust the motor position so the chain
is in line with the wheel.
The retainer and rods keep the beets from falling out of
the wheel elevator pockets on the way up. The retainer
frame must be centered right-and-left and front to back
with the wheel elevator. The distance between the
retainer and the wheel elevator must be the same at the
top as it is at the bottom. Make this adjustment at the
top attaching point. Make sure the retainer does not
make contact with the truck elevator. The distance from
wheel to the retainer should be approximately 1.5
inches (3.81 cm).
The retainer rod assembly is able to move away from
the wheel as more beets are conveyed. Field
adjustment is dependent on beet size, tonnage, and
mud controls. The spring adjusting nuts are used to
adjust the spring tension. Loosening the stop nuts will
decrease the tension. It is normally necessary to tighten
the stop nuts in muddy conditions to help clear mud
build-up. An additional set of holes are provided for the
spring bracket, if required for large beets and high
tonnage.

Figure 73 - Wheel Elevator Stripper.
The stripper disks (A) must be centered between the
wheel elevator rods so they do not make contact. Adjust
position so disks do not hit the cross tube weldments of
the wheel.
