TIMING MAGNETRONTM IGNITION

TM 5-4240-501-14P IGNITION Flywheel Type - MAGNETRONTM - External Breaker Fig. 28 - Sealing Breaker Cover TIMING MAGNETRONTM IGNITION 1 Gasoline - Position armature bracket so mounting screws are centered in armature bracket and tighten screws, Fig. 29A. 2. Kerosene - Position armature bracket to the right, as far as it will go and tighten screws, Fig. 29B. Fig. 29A- Gasoline Operation Fig. 29B- Kerosene Operation ADJUST ARMATURE TIMING WITH BREAKER POINTS MODEL SERIES 193000, 200000, 230000 , 243000, 300000, 320000 Remove Flywheel Use puller 19203 or 19068, running puller screws into holes tapped into flywheel. Continue to tighten screws until flywheel loosens, Fig. 30. NOTE: Use flywheel nut to protect crankshaft threads. Fig. 30 - Removing Flywheel Set point gap at .020" (0.5 mm). Position flywheel on crankshaft taper. Slip key in place. Install flywheel nut finger tight. Rotate flywheel and crankshaft clockwise until breaker points are just opening. Use a timing light. When points just start to open, arrow on flywheel should line up with arrow on armature bracket, Fig. 31. If arrows do not match, slip off flywheel without disturbing crankshaft position. Slightly loosen mounting screws holding armature bracket to cylinder, Fig. 31. Slip flywheel back on crankshaft. Insert flywheel key. Install flywheel nut finger tight. Move armature and bracket assembly to align arrows. Slip off flywheel, tighten armature bracket bolts. Install key and flywheel. Tighten flywheel nut to torque specifications listed in Table No. 1. Set armature air gap at .010"-.014" (0.25-0.36 mm), Fig. 32. Fig. 31 - Timing Marks 2 9
