JESEL’S BELT DRIVE SYSTEMS ARE THE MOST
ACCURATE AND DURABLE CAMSHAFT DRIVE
SYSTEM AVAILABLE AND ARE USED BY THE
COUNTRY’S TOP RACE TEAMS. A PATENTED
HIGH TORQUE BELT OPERATES WITHOUT
LUBRICATION AND SPINS WITH LESS FRICTION
THAN CHAINS OR GEAR DRIVE SYSTEMS. THE
R U B B E R B E LT A B S O R B S D E S T R U C T I V E
HARMONICS, WHICH CAN CAUSE SERIOUS
PROBLEMS ON RACING ENGINES. SOME
FEATURES INCLUDE A BILLET ALUMINUM
UPPER PULLEY WITH A HIGH TORQUE DRIVE
TOOTH CONFIGURATION AND AN ALLOY STEEL
CRANK PULLEY WITH GRADE 8 HARDWARE.
STEP 2
STEP 1
CHECK FOR COVER TO BLOCK INTERFERENCE AND
CORRECT IF PRESENT BY MODIFYING THE BLOCK.
CHECK FOR WATER PUMP AND BALANCER
CLEARANCE AS WELL.
IF YOUR BLOCK HAS BEEN LINE BORED, YOU MAY
ENCOUNTER A MISALIGNMENT BETWEEN THE
CRANK SEAL AND CRANK SNOUT. WE RECOMMEND ENLARGING THE DOWEL PIN HOLES IN THE
COVER AND LOOSELY INSTALLING THE COVER
BOLTS BEFORE DRIVING ON THE LOWER PULLEY.
THIS PROCEDURE WILL INSURE THAT THE CRANK
SEAL IS CENTERED AROUND THE CRANK SNOUT.
STEP 3
SECURE THE BELT DRIVE COVER TO THE BLOCK.
TORQUE THE COVER BOLTS TO 12 FT / LBS.
APPLY A THIN LAYER OF RTV SEALER TO THE RECESSED AREA ON THE CAM ADAPTOR.
LOCATE THE REAR THRUST WASHER (2.950”
OD X 1.960” ID X .031”), CAM ADAPTOR (ADP30080) CAM ADAPTOR BOLTS (5/16-18 X 3/4”)
AND SPANNER WRENCH.
WITH YOUR CAMSHAFT ON A WORKBENCH,
LUBRICATE AND INSTALL THE REAR THRUST
WASHER ON THE CAM SNOUT. APPLY SEALANT
TO THE THREADS OF THE CAM ADAPTOR BOLTS
AND BOLT THE ADAPTOR TO THE CAMSHAFT.
TORQUE CAM ADAPTOR BOLTS TO 28-30 FT/LBS.
STEP 4
LUBRICATE AND CAREFULLY INSTALL CAMSHAFT.
APPLY A THIN FILM OF OIL TO THE OUTER BRONZE
THRUST WASHER (2.950” OD X 2.260” ID X .031”)
AND INSTALL OVER THE NOSE OF THE CAM
ADAPTOR.
STEP 5
CHECK FOR CAMSHAFT END PLAY BY INSTALLING
ALL 3 THRUST SHIMS. JESEL INCLUDES (1) .010”,
(1) .015” AND (1) .020” THICK THRUST SHIM WITH
THIS KIT.
KEEP SHIMS DRY. DO NOT OIL OR USE ANY TYPE
OF SEALANT ON SHIMS
CAREFULLY INSTALL THRUST PLATE MAKING SURE
NOT TO DAMAGE CAMSHAFT SEAL ON ADAPTOR
KEYWAY. KEEP ALL SEAL AREAS DRY.
STEP 6
ADJUST CAMSHAFT ENDPLAY BY SETTING A DIAL
INDICATOR ON THE FACE OF THE CAM ADAPTOR.
ADJUST THE SHIMS UNTIL THE CAMSHAFT ENDPLAY IS BETWEEN .005” AND .010”.
REMOVE THRUST PLATE AND SHIMS. APPLY
A LIGHT FILM OF RTV S E A L A N T B E T W E E N
SHIMS TO PREVENT POSSIBLE OIL LEAKAGE.
REINSTALL SHIMS.
INSTALL THRUST PLATE AND TORQUE NUTS TO 12
FT / LBS. KEEP OIL OFF SEAL AREA. BE CAREFUL
NOT TO DAMAGE SEAL ON ADAPTOR KEYWAY.
STEP 7
LUBRICATE THE CRANK SNOUT WITH A HIGH
QUALITY ANTI-SEIZE COMPOUND.
A THIN LAYER OF RTV SEALANT MAY BE APPLIED
TO THE INNER CHAMFER OF THE LOWER PULLEY
TO PREVENT OIL SEEPAGE.
INSTALL THE PULLEY ONTO THE CRANK SNOUT
UNTIL THE PULLEY STOPS AGAINST THE CRANKSHAFT.
TO REMOVE LOWER PULLEY: ATTACH A PULLER
TO THE (3) THREADED HOLES. DO NOT PULL ON
THE RINGS OF THE PULLEY
STEP 9
STEP 8
ROTATE CRANKSHAFT SO THAT #1 CYLINDER IS
AT T.D.C.
ROTATE THE CAMSHAFT SO THAT THE KEYWAY IS
AT THE 12 O’CLOCK POSITION.
PLACE THE UPPER PULLEY ASSEMBLY ONTO
THE CAM ADAPTOR. LOCATE THE CAM ADAPTOR WASHER AND LEFT HAND THREADED CAM
ADAPTOR BOLT. START THREADING THE CAM
ADAPTOR BOLT INTO THE ADAPTOR. LEAVE
BOLT LOOSE.
TILT THE TOP OF THE UPPER PULLEY DOWN
TOWARDS THE CRANKSHAFT AND SLIDE THE
BELT OVER THE TWO PULLEYS. WITH THE
UPPER PULLEY ENGAGED FIRMLY INTO THE
CAMSHAFT ADAPTER KEY, TORQUE THE LH
BOLT TO 70 LBS-FT.
SET CAM TIMING TO DESIRED SPECS AND
TORQUE UPPER PULLEY NUTS TO 20-25 FT
/ LBS. INSTRUCTIONS FOR ADJUSTING THE
CAMSHAFT TIMING ARE ON THE BACK PAGE
OF THIS INSTRUCTION SHEET.
STEP 10
THE BELT DRIVE INSTALLATION IS NOW COMPLETE. PLEASE OBSERVE THE FOLLOWING
NOTES:
1) ALWAYS DOUBLE CHECK CAMSHAFT TIMING
BY USING A HIGH QUALITY DEGREE WHEEL.
2) ALWAYS DOUBLE CHECK YOUR PISTON TO
VALVE CLEARANCE. CHANGING CAM TIMING
CHANGES PISTON TO VALVE CLEARANCE.
3) IF THE BELT DRIVE IS GOING TO BE OPERATED IN AN ABRASIVE ENVIRONMENT, WE RECOMMEND COVERING THE UNIT TO PREVENT EXCESSIVE WEAR TO THE PULLEYS.

REQUIRES CRANK TRIGGER IGNITION SYSTEM
JESEL ALSO OFFERS A DISTRIBUTOR DRIVE KIT
FOR THE BIG-BLOCK CHEVY . THE DISTRIBUTOR
DRIVE KIT ELIMINATES INACCURATE IGNITION
TIMING SETTINGS DUE TO CAMSHAFT TORSIONAL
TWISTING ON HIGH RPM ENGINES WITH EXCESSIVE SPRING PRESSURES. IT ALSO PROVIDES A
MUCH COOLER LOCATION FOR THE DISTRIBUTOR. INTAKE MANIFOLD CHANGES WILL BE MUCH
EASIER AS WELL THANKS TO THE DISTRIBUTOR
NOT HAVING TO BE ROUTED THROUGH THE REAR
PORTION OF THE INTAKE MANIFOLD. THIS KIT IS A
DIRECT BOLT ON.
