ROTOR REMOVAL PROCEDURE
1. To remove the rotor, double check that the
spark plug wire is disconnected. 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.23. If an impact
wrench is not available, use the 1/2" 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 long thru-bolt supplied with
Lincoln Electric Rotor Removal Kit
S20925. 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
reverse thread bolt from the kit into the
rotor shaft until it bottoms out on the thru-
bolt.
5. With an impact wrench, tighten the
reverse thread bolt until the rotor pops off
the engine crankshaft. If an impact
wrench is not available, use the 1/2" box
wrench. Hold the rotor with one hand and
shock the wrench with the mallet until the
rotor pops off the engine crankshaft.
6. Slide the rotor and blower (press-fitted to
the rotor) the rest of the way off the crank-
shaft.
REASSEMBLY PROCEDURE
1. Lubricate the tapered engine crankshaft.
Slide the rotor onto the shaft.
2. Coat the rotor thru-bolt threads with
Lincoln E177-R retaining compound
(Locktite® 277). Place the beveled lock
washers onto the thru-bolt and insert it into
the rotor shaft. Hold the rotor and tighten
the thru-bolt to 22 - 25 ft lbs.
3. Carefully install the stator, with the leads at
the 1 o' clock position. IMPROPER HAN-
DLING OF THE STATOR CAN RESULT IN
SHORTED WINDINGS AND/OR LOST
OUTPUT.
