primary chaincase and put the stator in position
with the coil connections facing outwards.
Replace the nuts and shakeproof washers
only finger tight and insert six strips (preferably
of non-magnetic material) .015 in. thick and
about 1/8 in. wide between the rotor and each
pole piece.
Tighten the stator nuts and withdraw the
strips.
Check the air gap with narrow feelers and, if
less than .010 in. at any point, remove the stator
and file or grind the pole piece carefully until the
correct gap is obtained.
An alternative, and more satisfactory, method
of assembling the alternator requires the use of
Special Tool No. T2055.
This is a gauge .015 in. greater in radius than
the rotor and fits over the adaptor on the end of
the crankshaft in the rotor's place.
The stator is then put in position on the stud
in the chaincase and the nuts tightened up.
Remove the gauge and fit the rotor, then
check the air gap.
35. Removal of the Magneto
The magneto is bolted to the timing side
crankcase by the hexagon-headed screws.
Access to these is obtained by removing the
timing cover (Subsection 1) and the magneto
sprocket
and automatic advance device
(Subsection 25).
