MAINTENANCE
CUTTERHEAD
RAKERS
CUTTERBODY BOLTS
Using the wrong bolts or not keeping them tight allows for movement between the cutterbody and the support
arms which in turn leads to fatigue and failure. Once the cutterbody is allowed to run loose the integrity of the
hole in the support arm is lost and must be replaced. Otherwise the bolt will never be able to stay tight again.
Torque every bolt with a torque wrench. If you over torque these bolts, it can cause premature failure. Make
sure the cutterbody support arms are properly clamped on the cutterbody. The bolts alone are not enough to
secure the cutterbody in place. When replacing cutterbodies, the cutterbody bolts must be replaced as well.
WARNING
!
Rakers are designed to control the depth the cutter tooth will cut. The cutter tooth will take a larger cut the
more a raker wears. Depending on the screen being used larger cuts taken will not pass through and beat
around inside the cutterhead chamber until small enough to pass through the screen. Taking bigger cuts robs
horsepower used at the cutter tooth, puts stress on the cutterhead shaft that can cause shaft failure, cause
cutterbodies to stretch and fail prematurely, and cause the cutterbody bolts to bend or break.
The hard surface weld on the replaceable raker or the raker area must be maintained. See Figure 1
for maximum allowable wear. While on the machine the measurements can be taken from the face of the
cutterhead. When worn either replace the replaceable raker, or remove the cutterbody and build up the raker
area with a hard surface weld using the dimensions in Figure 1 as a guide. If there is excessive wear to the
raker it is recommended to replace with a new one. Do not build up the worn area more than the height shown
in Figure 1. It will affect how the machine feeds.
If building up a non replaceable raker, it is recommended to use “Lincoln Lincore 60-0” or “Stoody 101HC”
wire if using a wire feed welder; if using a stick welder it is recommended to use “Lincoln Wearshield 60” or
“Stoody Stoodite 2134”.
Never weld on the cutterbodies while they are on the machine. This can cause a fire.
