9.) Torque rotor knives to 50-55ft./lbs. Requires torque wrench and 5/16” Allen drive socket bit.
10.) Set clearance between rotor and bed knives to .001” using adjustment screws and a feeler
gauge, rotating the knives in reverse (clockwise) so “flat to flat” contact will not cut feeler gauge.
• Requires 7/16” wrench and .001” feeler gauge.
• Process will need to be repeated until proper clearance is achieved.
• You will hear a light knock while spinning the rotor when one or two rotor knives
meet the feeler gauge. This indicates proper clearance.
o There should be little resistance, just a noise.
o If the rotor stops, there is too little clearance.
o The knocking only occurs on the longest of the three rotor knives.
Occasionally it will occur for two knives.
• 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.
• Double check clearance after tightening bolts as gap should be checked on each
knife on rotor and across the whole surface of each knife.
