Hi Everyone,
Now available. For both Supercharged and naturally aspirated Viper engines (remember the one or two non Supercharged engines at the VOI drags that had their crankshaft hubs spin off?).
Priced at $59.95
Instructions and all parts included. Instruction text below.
DODGE VIPER CRANKSHAFT HUB PIN TOOL INSTRUCTIONS
Purpose:
The crankshaft hub on the Viper engine is not keyed. This in itself is not a problem as long as the hub-retaining bolt is tight (factory torque of 250 ft / lbs). The torque of the bolt, pressing the hub against the end of the crankshaft, is what keeps the hub from spinning due to accessory drag. However, if the bolt is loose and the hub begins to turn, the bolt will loosen rapidly as the bolt threads are right hand thread.
In order to keep the bolt from spinning loose if not properly torqued, we have created this pinning tool. Each roll pin has a double shear strength of over 7,000 lbs. The factory hub bolt will still need to be torqued to factory specifications. The pins enhance the bolt's ability to remain torqued.
1. Remove the factory air filter housing, serpentine belt and crankshaft pulley in order to gain access to the crankshaft hub.
2. Remove the crankshaft hub bolt (requires a 1&1/4" socket).
3. Bolt the drill bit guide tool onto the end of the hub using the provided socket head bolt. The tool will locate on the step at the face of the hub. Position one of the holes at the 12 o'clock position.
4. Mark the supplied drill bit at 2.40" to 2.45" (inches) from the tip end. When you drill into the tool, hub and crankshaft, you must stop drilling when this point lines up with the outside end of the tool. Do not drill any less or any more than this depth. Check the depth when you are almost there.
5. Drill the hole at the top first. Apply firm drill pressure at a medium speed with no oil. Turn the crankshaft 180 degrees, bringing the lower hole to the top. Drill the second hole at the same depth.
6. Remove the tool and install the two roll pins. Install the pins such that the open end is toward the center. The end of the pins should be at, or slightly lower than, the face of the crankshaft hub. If the hole was not drilled deep enough and they are protruding beyond the face, grind them flush with the hub.
7. Install the crankshaft hub bolt with red Loctite. Torque to 250 ft / lbs.
8. Install the crankshaft pulley, serpentine belt and any other items removed.
