ENGINE/ROTOR REMOVAL AND REPLACEMENT PROCEDURE (cont.)
REASSEMBLY PROCEDURE
NOTE: Lincoln Electric recommends that a new bear-
ing 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 locking pliers as necessary
so that the rotor "iron" is up to take the measure-
ment. (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 mount-
ing bolt and install both bolts.
7. Install the brush holder bracket back into the sta-
See the Brush Removal and
tor frame.

TROUBLESHOOTING AND REPAIR
RANGER® 3 PHASE
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 position
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 sta-
tor.
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 battery
cable, then the negative battery cable. BE SURE
TO CONNECT THE POSITIVE BATTERY CABLE
FIRST.
18. Replace the battery cover.
19. Reinstall the case side, fuel cap, lift bail gasket,
and case top. Connect the spark plug wires.
