FIGURE F.13 - ENGINE AND ROTOR REMOVED FROM STATOR
ENGINE/ROTOR REMOVAL AND REPLACEMENT (continued)
ROTOR REMOVAL PROCEDURE
1. To remove the rotor, double check that the
engine spark plug wires are disconnected.
You will be turning the rotor during this proce-
dure, and this could accidentally cause engine
kickback.
2. With an impact wrench, remove the rotor thru-
bolt. See Figure F.13. If an impact wrench is
not available, use a 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 washer 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 approximately 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 crank-
shaft. Be careful not to lose the washer that fits
between the blower fan and the rotor.
