4-3 Module Assembly
Insert a gauge (3350-96240/ 521 06 82-01) between
the rotor magnet metal and module. Tighten the bolts
while pushing the module against the rotor.
NOTE: Apply Lock Tight (Medium strength type:
Threebond 1342, LOCTITE 242 or equivalent to) to
the bolts.

The resistance values shown above are the reference values for resistance tester
measurement. A resistance value is within the normal range shows no internal leakage
or any other defect.
We supply the measurement equipment (gap tester) that can measure spark energy
while the engine is running.
4-4 Piston Pin Removal
1. Remove the snap rings from both sides of the
piston pin.
2. Engage the rod assy (1101-96220/ 516 18 29-01)
