8.
Torque rotor knives to 50-55ft./lbs. Requires torque wrench and 5/16” Allen drive socket bit
9.
Set clearance between rotor and bed knives to .005” using adjustment screws and a feeler gauge, rotating the
knives in reverse (clockwise) so “flat to flat” contact will not cut feeler gauge.
o
Requires 7/16” wrench and .005” feeler gauge.
o
Process will need to be repeated until proper clearance is achieved.
o
You will hear a
light
“knock” while spinning the rotor when one or two rotor knives come into contact
with the feeler gauge. This indicates proper clearance.
§
There should be little resistance, just a noise.
§
If the rotor stops, there is too little clearance.
§
The knocking only occurs on the longest of the three rotor knives, occasionally it will occur for
two knives.
o
Check clearance in front of each bed knife bolt. The “knocking” should occur either in the middle OR on
the two outside bed knife bolts.
o
Double check clearance after tightening bolts as gap should be checked on each knife on rotor and
across the whole surface of each knife.
