4. Install the end bracket.
install the two top thru-bolts loosely to hold
the end bracket for the next step.
5. Install the end bracket support.
6. Install the bottom two end bracket thru-
bolts.
7. Tap the end bracket with the mallet as nec-
essary to position it. Tighten the bolts to
22 - 25 ft lbs. Alternate tightening in order
to pull the assembly together evenly. As
you tighten, look through the brush hous-
ing access door and watch the bearing to
judge end bracket movement and align-
ment.
8. Check the rotor-stator air gap with the long
.010 feeler gauge.
taken through the brush holder access
door; see Figure F.24. Turn the engine with
the recoil starter rope slightly 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 end bracket thru-bolts,
reposition the end bracket, retighten the
bolts, and recheck the air gap. Repeat until
the proper .010 minimum air gap is
achieved (.030 maximum).
