Fluidampr 300002 Performance Harmonic Balancer
Tools & Procedures
- Proper key if required
- Anti-seize compound
- Removal & installation tool if required (Damage from improper installation will void your warranty)
- Do not use hammers/pry bars or heat to install or remove Fluidampr. (This will void your warranty and may cause engine damage)
- Honing or machining Fluidampr bore is not recommended (on applicable applications). A diametrical press fit (on press fit only dampers) of .0005” – .0015” is recommended for proper damper function. Using a micrometer, make sure to measure the crank snout and inner bore of Fluidampr to assure a proper fit.
- Sufficient torque wrench (see torque specs on page 2), fan removal tools, flywheel holding tool (if required).
CAUTION : For high horsepower applications we recommend the following
Balancing – Internally and Externally Balanced Engines
REPLACING THE DAMPER
Fluidampr counterweights for external balanced engines have been designed to
OEM specifications. If the damper being replaced has never been altered,
Fluidampr can be installed with no additional balancing. (see page 2 for
whether your Fluidampr is internally or externally balanced)
BALANCING OR MATCH BALANCING
- Each Fluidampr component is precision balanced during manufacturing. NO additional balancing is required.
- DO NOT ATTEMPT TO BALANCE THE CRANKSHAFT WITH FLUIDAMPR INSTALLED. The inertia ring inside a Fluidampr is balanced to a close tolerance at the factory. It rotates inside the damper.
- DO NOT DRILL FLUIDAMPR – The inertia ring and silicone fluid are in a hermetically sealed housing. Drilling may cause the damper to leak and lead to damper failure, voiding the warranty.
- If balancing the crankshaft is required, install the stock damper while balancin
Removal
- Remove fan and shroud as per manufacturer’s instructions, draw sketch of belt routing if required and remove the accessory drive belt.
- Dodge Cummins 5.9L (1992 to 1998). BEFORE REMOVING THE STOCK DAMPER, rotate the engine so that the magnetic pick up is not on one of the notches in the outside diameter of the stock damper. If you do not have access to the gap spec, use a feeler gage to measure and record the gap between the magnetic pick up and the stock damper.
- Remove the stock damper per factory/service manual instructions
Fluidampr Installation
- On engines that the damper slides or presses onto the crankshaft, carefully remove burrs, scratches, or nicks on the crank snout by filing or polishing the snout so that it is smooth and free of surface irregularities. Remove any sharp keyway corners. The key should fit snugly in the keyway on the crank. A heavy press fit creates high stress on the slot and should be avoided. Replace or modify the key if it is too tight or too loose. For bolt-on dampers, clean crankshaft threads, crankshaft mating surface and center pilot thoroughly before installation.
- Cummins installation notes:
- Fluidampr P/N 920301 includes tone wheel. Remove OEM tone wheel prior to Fluidampr installation.
- Fluidampr P/N 920301/920321/980301 – Install damper w/ the smaller of the (2) pin holes on the crankshaft pin. Check crankshaft thread depth to ensure proper bolt length prior to installation.
- Thread bolts into crankshaft fully with washer installed. Space between washer and crankshaft should be less than 0.495” (Fluidampr flange thickness with integrated tone wheel). If the length is over 0.495”, contact Fluidampr Tech Service. Minimum thread engagement = .750”
- Coat crankshaft snout and damper bore with anti-seize compound or moly grease to prevent galling during installation.
- Fluidampr P/N’s 760131, 830111, 830121, 830141, 830151, 890101 come with a hardened crankshaft washer with clearance for the GM 3.200” bolt circle pattern, this replaces the factory crankshaft bolt washer.
- For Ford Power Stroke 6.0L: The belt must be routed between the Fluidampr and the water pump pulley before the Fluidampr is installed.
- Install the Fluidampr and torque the bolt or bolts properly as per the original manufacturers’ torque or torque to yield requirements. Consult a dealer to determine if your application is torque to yield, see below chart for torque specs.
- Fluidampr recommends that crank bolt(s) always be replaced with new OEM or Fluidampr bolt kits.
- Install the accessory drive belt, fan and shroud as per manufacturer’s instructions. Re-torque crankshaft bolt(s) after engine warm-up cycle.
WARNING : FAILURE TO USE PROPERLY TORQUED BOLTS WILL VOID WARRANTY AND COULD RESULT IN DAMPER, KEY, OR CRANK DAMAGE. ONLY USE THESE TORQUE VALUES WHEN INSTALLING DAMPER WITH OEM BOLTS. *BOLTS ARE TORQUE TO YIELD AND NEW BOLTS MUST BE USED EVERYTIME
