Centerforce Dual-Friction Clutch Kits

1 LUTH AND FLYWHEEL

2 enterforce Dual-Friction lutch Kits Dual-Friction lutch Kits are designed specifically for autocross and racing applications. A race-proven centrifugal weight system on the pressure plate generates up to a 90% increase in holding capacity over a stock clutch with a minimal increase in clutch pedal pressure. The Dual-Friction clutch disc features unique carbon-fiber facings. arbon-fiber facings are lighter, more heat and oil resistant and less abrasive than metallic facings commonly used on most other high performance/racing discs. All enterforce lutch Kits include pressure plate and disc. A stock Mazda factory release bearing should be used with enterforce clutches. ENTERFORE DUAL-FRITION LUTH KIT ODE REQ.

4 Aluminum Flywheel For 5-/2" lutches This unique lightweight flywheel for 5-/2" racing clutches weighs approximately 4 pounds and features a steel center heat shield for durability. Due to its integral ring gear (part of the aluminum outer hub), the moment of inertia on the flywheel is comparable to all-aluminum flywheels. The aluminum outer hub can be replaced when necessary (when ring gear teeth become worn). Another unique feature this flywheel offers is that it can be used with a bottomor top-mount starter (mounting position). Remounting the center steel heat shield to one side or the other of the aluminum outer hub accomplishes this. Important safety note: Allen-head mounting bolts should be replaced periodically use only aircraft quality bolts.

5 Quarter Master lutches Quarter Master clutches provide ultimate performance at high rpms and temperatures without the failures sometimes common to other clutch designs. Features and benefits include: Low moment of inertia Lightweight aluminum clutch cover Unique closed-style design Improved sintered metal friction material that eliminates dusting Allows harder, faster acceleration and deceleration into and out of corners Highest torque capacities and lowest wear rates lutch & Flywheel All Quarter Master clutches and flywheels are built with the intent of making them as inertially light as possible, without sacrificing durability. We offer both the Quarter Master 7-/4" and 5-/2" 2-disc clutch assemblies for rotary applications. Quarter Master 5-/2" lutch Unit The lightweight 5-/2" clutch unit with aluminum flywheel provides approximately 30% less rotational inertia and weight than the Quarter Master 7-/4"clutch unit with aluminum flywheel. It only is available for bottom mount starter applications with an aluminum flywheel. QUARTER MATER LUTHE REQ.

In addition, be sure that a pedal stop has been installed to prevent clutch from going over-centering. *Quarter Master clutches require the use of a special radius-faced release bearing. Do not use a flat-face bearing with any Quarter Master clutch.

6 Quarter Master lutch Replacement Parts When replacing clutch packs, be sure to check the floater plate and pressure plate for any sign of wear or warpage. We also recommend that you carefully check the condition of the pilot bearing. A worn pilot bearing can significantly reduce the service life of your clutch and transmission.

8 Moment of Inertia Moment of inertia, with respect to rotation, is called angular momentum. Angular momentum is the force that has to be overcome to spin a circular component (e.g., a flywheel and clutch). It is the function of the mass of the part and the radius on which the mass is positioned. The more centered the mass is on a circular part, the lower the angular momentum, and the less horsepower is needed to spin the part. This translates to the flywheel/clutch assembly being able to accelerate faster at every rpm range. For example, Quarter Master s aluminum flywheel and 7-/4" aluminum clutch unit together are rated at 46.3 inch-pounds. In other words, the assembly requires approximately 46.3 inch-pounds of force to initiate movement. QM s aluminum flywheel and the new compact 5-/2" aluminum clutch unit require approximately 0 inch-pounds of force to initiate movement (a 30% reduction).
