2.
Insert the T-118 timing pin in
"L"
or "R" hole (depending on magneto rotation) in the
distributor block. Turn rotor in the opposite rotation of magneto until pin engages the gear,
install magneto and gasket on mounting pad of accessory housing and remove timing pin.
Secure tightening bolts finger tight.
3.
Connect a standard timing light between engine ground and left magneto condenser
terminal. Switch must be
"ON".
4.
Turn the complete magneto opposite normal rotation of the magneto on engine mount
until the timing light indicates the contact breaker points are just opening. Secure magneto.
Turn switch "OFF.
5.
Turn on the switch of the timing light. Rotate the crankshaft slowly in direction
of
normal rotation until the timing mark on the front face of the starter ring gear aligns with
the drill hole in the starter housing, at this point the light should illuminate.
If not, turn
magneto in its mounting flange slots and repeat until light illuminates at the 20 degree BTC
indication. Secure magneto.
6.
Connect other positive wire of timing light to right magneto condenser terminal and time
the magneto in the same manner as left magneto.
7.
Following timing of both magnetos, with timing light wires still connected, recheck
magneto timing as previously described to insure that both magnetos are timed to fire
together. If timing is correct,
both lights will illuminate simultaneously when the
20
degree
indication on the ring gear aligns with the drill hole in the starter housing. If points open
early, loosen magnetos and rotate counterclockwise. Secure magnetos and remove timing lights.
CAUTION
. . .
When installing the magneto on the engine using the available nuts and clamps,
please take the following precautions. Tighten both nuts by hand to finger tightness. Tighten
each nut to
8
ft.1bs. and then tighten them alternately in several steps to 17 P-lbs. Exceed-
ing 17-..-lbs. may cause the
mountingpange to crack
For further information on the magnetos and ignition system refer to the applicable manufac-
tures instructions.

HARNESS ASSEMBLY INSTALLATION
Before installing harness on magneto check mating surfaces for cleanliness. install and tighten
nuts around plate alternately to seat cover squarely on magneto. Torque nuts to 18-22 in.-lbs.
The harness assemblies are constructed of a lightweight, flexible, silicone coated cable having
a
400~~. temperature rating. Because the harness assemblies are lightweight and flexible, the
following suggestions should be observed when installing the harness on an engine:
A.
Support leads with as many clamps and cable ties as are necessary to prevent any
whipping or chafing action.
B.
Route leads as far away as possible from exhaust manifold to insure they are not exposed
to temperatures in excess of
400~~.
C.
To prevent sticking of sleeves and to minimize twisting of ferrule, coat insulating
sleeves* and lubricate ferrule shoulders**. Fasten coupling nuts to the proper spark plugs and
torque as specified in Table
11.
Tighten elbow assembly nuts to outer ferrule.
