ROTOR REMOVAL PROCEDURE

1.To remove the rotor, double check that the engine spark plug wires are disconnected. You will be turn- ing 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.13. If an impact wrench is not avail- able, use a 5/8” box wrench or socket. Hold the rotor with one hand and shock the wrench with a 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 pro- vided) 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 crankshaft. Be careful not to lose the washer that fits between the blower fan and the rotor.
