CAUTION: READ INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION
INTRODUCTIONCrane Hall Effect crank trigger systems provide
absolutely stable and accurate ignition timing for profes-sional racing applications. Part numbers 9000-1100(Chevy small block) and 9000-1101 (Chevy big block) arecomplete kits that include the crankshaft trigger wheel,Hall Effect sensor, sensor mounting bracket, and allrequired hardware. The Chevy small block crank trigger kitwill fit most engines using dry sump oiling systems andstock harmonic dampers. The Chevy big block crank trig-ger kit will fit most aftermarket harmonic dampers. Partnumber 9000-1000 is a sensor only upgrade kit that canbe used with most Accel, Holley, MSD, and Moroso flyingmagnet crank trigger systems using ¾-16UNF threads forsensor mounting.
Unlike conventional magnetic sensors that respond tochanges in the magnetic flux as the magnet passes thesensor, the Hall Effect principle senses the actual mag-netic field strength. It precisely senses magnet positionregardless of rotational speed and is less sensitive to vari-ations in gap between the sensor and wheel. Timing scat-ter is greatly reduced. Timing variations with RPM areeliminated and the system can even be used to set statictiming. The Hall Effect sensor includes an internal amplifi-er that generates both a conventional magnetic trigger sig-nal and a very robust 12 volt square wave type trigger sig-nal (commonly referred to as a points type signal). Thepoints type signal offers much greater RFI noise immuni-ty. The trigger signals are compatible with most aftermar-ket ignitions including Crane HI-6, HI-7, HI-8 and MSD 6,MSD 7, and MSD 8 systems. The Hall Effect crank triggercan also be used in conjunction with engine controls suchas the Crane DEC9000 series or timing controls such asthe Crane TCU-1.
INSTALLATION OVERVIEWIf you are upgrading an existing flying magnet crank
trigger system with a Crane Hall Effect sensor, skip aheadto the Sensor Upgrade section on page 3. If you areinstalling a complete Crane crank trigger system - installthe arm and pickup bracket first, then install the trigger
wheel. Location of the sensor will determine the choice oftrigger wheel mounting holes.
ARM & PICKUP BRACKETINSTALLATION1. Mount the pickup bracket onto the adjustment arm
using two fine thread bolts and washers. Refer toFigure 1 for small block installation or Figure 2 for bigblock installation. The bracket retention plate receivesan off center dowel pin. If the bolt holes do not line up,rotate the retention plate 180 degrees. Position thepickup bracket in the center of the adjustment slot andfinger tighten the bolts at this time.
2. The adjustment arm can be installed on either the leftor right side of the harmonic damper. Select the sidethat is best suited for your application. Starting with a1/2” spacer combination (one 3/16” spacer and one5/16” spacer), mount the bracket and arm assembly tothe engine block using two coarse thread bolts. Referto Figures 1 or 2. Finger tighten the bolts at this time.
3. Thread the supplied jam nut onto the Hall Effect sen-sor. Screw the sensor into the pickup bracket. Do nottighten the jam nut at this time.

WARNING: Do not come into contactwith the coil primary wires or the sec-ondary plug wires while the engine isrunning. Disconnect battery groundbefore performing any work on theengine.The ignition will fire if the key ison and the engine is rotated at any RPM,even very slowly. Do not connect a tim-ing light or other test equipment to anycoil terminal.

TRIGGER WHEEL INSTALLATION1. Rotate the crankshaft until the #1 cylinder approaches
TDC and the crankshaft is at the desired timing angle(degrees BTDC where you want the spark to fire).
2. Small block Chevy engines only: select and install thecorrect trigger wheel alignment ring for your applica-tion.
3. Fit the trigger wheel recess over the harmonic damperboss. Rotate the trigger wheel (and alignment ring ifused) until the mounting holes line up with the damperand one of the four magnets is located near the cen-terline of the Hall Effect sensor. Note that the pulleyspacers may require machining to provide proper beltalignment after trigger wheel installation. Use three finethread bolts to secure the trigger wheel to the harmon-ic damper. Torque these mounting bolts to 25 - 30 ft-lbs.
4. Use a dial indicator (base mounted to the pickup brack-et or crankcase). Rotate the engine by hand and verifythat the run out of trigger wheel is less than .015” TIR.
Then rotate the crankshaft back to the desired timingangle as in step 1.
5. Refer to Figure 4. Align the centerline of the Hall Effectsensor with the centerline of the trigger wheel magnet.This action will also establish static timing accurate towithin a few degrees. Addition or removal of spacersbehind the adjustment arm may be required to pre-cisely align the sensor to the wheel.
6. Set the air gap between the trigger wheel and the sen-sor between .045” - .060”. Tighten the sensor jam nutand all other hardware that was previously finger tight.Skip ahead to the Ignition System Hookup section onpage 3.

SENSOR UPGRADE
Remove the existing magnetic crank trigger sensorfrom the pickup bracket. Thread the supplied jam nut ontothe new Crane Hall Effect sensor. Screw the Hall Effectsensor into the pickup bracket. Set the air gap between thewheel and the sensor between .045” - .060”. Tighten thesensor jam nut.
IGNITION SYSTEM HOOKUP
1. The Hall Effect sensor is provided with an extensionharness. Route the extension harness close to framerails. To avoid false triggering from noise, keep theextension harness away from the ignition coil, coilwiring, and spark plug wires. Secure the extension har-ness with supplied nylon wire ties.
2. For hookup of the most popular Crane and MSD igni-tion configurations, refer to Figures 7 - 14.You can usea hookup similar to Figure 7 for most other systemswith a points trigger input.
3. +12V. Connect the red wire from the sensor to +IGNon ignition system or direct to ignition key or otherswitched +12V source.
4. GROUND. The shield wire from the sensor is ground.Connect the shield wire to the ground terminal on theignition system or direct to chassis ground.
5. POINTS. If you are using points trigger, connect thewhite wire from the sensor to the points input terminalon the ignition system. When triggering an MSD 8 igni-tion, connect the white points wire to the Mag+ termi-nal. Refer to Figure 12.
6. MAGNETIC TRIGGER. If you are using magnetic trig-ger, connect the black wire from the sensor to theMAG+ input terminal on the ignition system.
DISTRIBUTOR ROTOR PHASING
1. When using a crank trigger system, the distributor nolonger controls the ignition timing, but you must still setthe correct rotor phasing. If you are using a centrifugaladvance distributor, lock up or weld up the advancemechanism. Otherwise rotor phasing will change withRPM.
2. Refer to Figure 5. Rotate the crankshaft until the #1cylinder approaches TDC and the crankshaft is at thedesired timing angle (degrees BTDC where you wantthe spark to fire).
3. Loosen the distributor hold down clamp and rotate thedistributor until the rotor is directly aligned with the #1terminal on the distributor cap. Then tighten the holddown clamp again. This establishes rough rotor phas-ing.
CAUTION: Incorrect rotor phasing cancause loss of ignition energy or enginedamage from crossfiring.
CAUTION: Depending on your applica-tion, you can use either the points ormagnetic trigger signal from the HallEffect sensor. Do not attempt tohookup both signals. If your ignitionhas a points input, you should use thepoints trigger connection for optimumnoise immunity.
CAUTION: The Crane Hall Effect sensorcan only be used with flying magnettype crank trigger systems with ¾-16UNF threads for sensor mounting.The Hall Effect sensor will not functionwith older variable reluctance typecrank trigger systems (wheels withlugs or projections, but without embed-ded magnets).

TIMING ADJUSTMENT AND PRECISEROTOR PHASING
1. Start the engine and check the ignition timing. If youare upgrading the sensor in an existing crank triggerinstallation, timing may change several degrees andrequire re-adjustment. You can adjust the ignition tim-ing by sliding the Hall Effect sensor and bracketassembly in the adjustment arm slot as shown inFigure 5. To retard the timing, slide the sensor and
bracket assembly in the same direction as crankshaftrotation. To advance the timing, slide the sensor andbracket in the opposite direction. Check the sensor totrigger wheel air gap whenever you adjust the timing.
2. To check the rotor phasing, cut or drill a large hole inthe distributor cap near a terminal as shown in Figure6. Use a timing light connected to that terminal andobserve rotor alignment when the engine is running.The rotor tip should be aligned with the terminal asshown in the figure. If not, you must rotate the distribu-tor to achieve proper alignment. Install a new distribu-tor cap when you are done.
TROUBLESHOOTING HINTSDid the engine run properly before installation of the
crank trigger system? If not, remove the crank trigger sys-tem and then find and correct the original problem. Did theHall Effect sensor ever function correctly? If the answer isyes, did you change anything that may have affected oper-ation? If the engine will not start, runs rough or intermit-tent, double check all electrical connections. Try a differ-ent ground connection point. Use a voltmeter to verify +12volts at the red wire from the sensor. Make sure you havepower when the engine is cranking. During cranking, thesensor will operate down to +5 volts.
You can verify a trigger pulse by connecting a +12 volttrouble light between +12 volts and the white points wire ofthe Hall Effect sensor. The light will momentarily flashwhen a magnet passes the sensor. If you have a Craneignition with diagnostic LED, the LED will blink whenever atrigger pulse is received. Above cranking RPM, it willremain lit.
WARNING: To avoid personal injury, donot adjust timing while the engine isrunning. Before starting the engine forthe first time, double check all electri-cal connections.
