Part Number PRD-7121

After the initial inspection, the complete inspection process must be repeated after every 5 hours of use.
When the gear plate has reached 40 hours of total use it must be replaced.
NOTE: The use of screwdrivers and pry bars to remove the gear plate/clutch center will damage the part causing premature failure. Only use the PRD clutch center puller to remove the clutch plate (part # PRD-7193). When reinstalling do not over tighten the three (3) gear plate bolts, maximum torque 144 inch pounds/12 foot pounds with red lock tight.
Possible gear plate failure may occur as a result of improper removal, reinstallation or use beyond the expected life of the product.
WARNING: If failure occurs, the engine will be under power. The gear plate could potentially separate from the main gear at a high rate of speed causing damage or injury.

The event went off in the Fan Zone located directly in front of the main grandstands in full view of all who entered the speedway.

Otherwise a flawless event, one slight hiccup during practice on Friday initiated a minor modification to the track for spectator safety. The 18-turn 6/10ths of a mile track was fast, with a 650′ back straight. The red flag never flew all weekend long, a testament to the quality of the layout and the drivers. The track crew did a fantastic job and the officiating was spot on all weekend. Continue reading PRD Pan Am Crown of Karting makes a successful debut at AutoClub Speedway with the IZOD IndyCars
