REASSEMBLY PROCEDURE

NOTE: Lincoln Electric recommends that a new bearing (Lincoln part #M9300-85) be installed when you replace the rotor and blower assembly.

1.Clean the tapered engine crankshaft. Slide the rotor onto the shaft.

2.Insert the rotor thru-bolt, and with the torque wrench tighten the bolt to 50 ft lbs.

3.Support the engine/rotor assembly with the chain hoist. Fit the rotor into the stator frame, being careful not to damage the rotor core against the stator. The bearing will seat into its race about half way.

4.Insert the four bolts and lock washers that hold the engine to the stator. With the 9/16” wrench, draw the bolts up evenly in order to seat the bearing properly. Tighten to 22 ft-lb. moving diagonally from bolt to bolt.

5.Check the rotor-stator air gap with the .017 feeler gauge. The measurement is taken at the blower end of the rotor before the fan is reinstalled. Turn the rotor with a pair of lock- ing pliers as necessary so that the rotor “iron” is up to take the measurement. (The rotor has two flat sides, which are not measured for air gap.) Slide in the gauge. Then rotate the shaft 180 degrees and measure again. If the gauge does not clear, loosen the four engine/stator bolts; retighten the bolts and recheck the air gap. Repeat until the proper

.017 minimum air gap is achieved.

6.Fasten the ground lead to the right engine mounting bolt and install both bolts.

7.Install the brush holder bracket back intoBrushthe Removalstator frameand. ReplacementRefer to the topic “

”in this section of

the manual.

8.Attach leads to the oil pressure switch refer to wiring diagram. Replace any cut cable ties.

9.Unplug the fuel tank connection and fuel hose and connect them.

10.Connect the idle linkage to the idler rod. Snap the plastic clip back into place.

11.Connect the engine choke cable at the posi- tion marked during disassembly.

12.Screw the blower fan back onto the end of the rotor shaft. Be sure the washer is in place and hand tighten the fan only.

13.Reposition the vertical fan baffle and secure it with the two screws.

14.Install the two cowling covers at the rear of the stator.

15.Connect the black plug in front of the fuel tank fill spout.

16.Connect the leads to the starter solenoid and replace any cable ties cut during disassembly.

17.Install the battery. Connect the positive bat- tery cable, then the negative battery cable. BE SURE TO CONNECT THE POSITIVE BAT- TERY CABLE FIRST.

18.Replace the battery cover.

19.Reinstall the case side, fuel cap, lift bail gas- ket, and case top. Connect the spark plug wires.

20.Conduct the “Retest after Repair” procedure, the following topic in this section of the manu- al.
