ROTOR REMOVAL PROCEDURE
1. To remove the rotor, double check that the
engine spark plug wires are disconnect-
ed. You will be turning the rotor during this
procedure, and this could accidentally cause
engine kickback.
2. With an impact wrench, remove the rotor
thru-bolt. See Figure F.15. If an impact
wrench is not available, use the 5/8” box
wrench. Hold the rotor with one hand and
shock the wrench with the mallet to loosen
the thru-bolt. The thru-bolt has a star wash-
er and lock washer, beveled to conform to
the rotor shaft. Pull out the thru-bolt.
3. Install the appropriate long thru-bolt (two are
provided) supplied with Lincoln Electric
Rotor Removal Kit S20788. The slot head
must face out. Screw in the bolt with the slot
head screw driver until the bolt bottoms out
on the engine crankshaft, about 3/4”.
4. Turning it counterclockwise, screw in the
left-hand thread rotor removal tool from the
kit into the rotor shaft. Support the rotor with
one hand and tighten the tool to approxi-
mately 50 ft lbs with the torque or impact
wrench.
5. If the rotor does not pop off, tighten the rotor
removal tool an additional 5 ft lbs. Hold the
rotor with one hand until the rotor pops off
the engine crankshaft.
HINT: If the rotor does not pop off, hit the end
of the rotor removal tool with a hammer.
6. Slide the rotor the rest of the way off the
crankshaft. Be careful not to lose the wash-
er that fits between the blower fan and the
rotor.
