I20MI033 SST Twin Disc Clutch
IMPORTANT
SST (Solid Street Twin) Installation:
Your new SST Twin Disc clutch set is like no other high-performance clutch on
the market. Take a moment to read the following instructions.
Note that your new SST twin disc clutch assembly has already been precision
balanced. During nal assembly be sure the corresponding pressure plate, oater
and ywheel balance markings (located on the outer diameter of the clutch
assembly) are all in alignment.
Your SST Twin Disc clutch has been designed to work in conjunction with most
factory O.E. bellhousings and clutch release mechanisms without modi cation.
However, installing a new clutch release bearing is always recommended during
every new clutch install.
Please be aware that vehicles with HYDRAULIC clutch release systems MAY HAVE
an aftermarket shim or spacer installed between the release bearing and
transmission PLEASE CHECK! Your SST clutch system WILL NOT WORK in
conjunction with ANY aftermarket shim or spacer between the release bearing
and transmission.
-
Carefully unpack your SST twin disc clutch system. Your new clutch assembly has been shipped from the factory exactly as it should be installed in your vehicle. Remove the pressure plate assembly from the ywheel and take careful note of the placement of each component.
-
Please take special care of the three 1/4″ diameter anti-rattle pins located on the outer diameter of the ywheel, facing toward the oater plate. Use caution and DO NOT bend or alter these pins.
-
Also, please take note of the six spacers located on the pressure plate studs between the clutch pressure plate and ywheel. Please be sure these spacers remain in place exactly as they were shipped.
-
Install the new clutch pilot bearing supplied (where applicable).
-
Install the ywheel to your engine; USE ONLY the ywheel to crankshaft bolts supplied with this clutch assembly. Torque the ywheel to crankshaft bolts to the supplied speci cations.
-
Install the ywheel disc as marked (“Flywheel Side” decal toward the ywheel). Hold the ywheel disc in place and align with the enclosed disc alignment tool. Keep the disc alignment tool centered and in place until the clutch Pressure Plate is fully bolted to the ywheel.
-
Be sure to align the balance index mark on the oater plate to the balance index mark on the ywheel then, install the oater over the three oater drive spools located within the ywheel. The oater ant-rattle pins will locate within the oater plate, 3 places.
Note: the oater drive spools are secured to the ywheel with threadlocking compound and have
been pre-torqued to the ywheel from the factory. Please do not remove or further tighten the three socket head (Allen head) bolts retaining the oater drive spools. -
Install the pressure plate disc as marked (“Floater Side” decal toward the oater).
-
During assembly, be sure to align the balance index mark on the pressure plate to the balance marks on the ywheel/ oater plate.
-
Install the clutch pressure plate over the pressure plate studs located within the ywheel. (Note: the clutch pressure plate studs are secured to the ywheel with threadlocking compound from the factory. Please do not remove or further tighten the six clutch pressure plate studs).
-
Threadlocking compound may be used to secure the pressure plate nuts to the ywheel studs if so desired. If using threadlocker on the pressure plate nuts, use only a SMALL amount of MEDIUM (blue) threadlocking compound. Tighten all six pressure plate nuts, ¼ turn at a time in a criss-cross pattern until the pressure plate is completely drawn-up to the spacers against the ywheel. Torque all six nuts to 35 38 ft/lbs.
-
Remove the disc alignment tool and install the transmission.

Please follow these instructions to maintain the warranty of your Centerforce®
product!
Flywheels: All Centerforce® clutches need to be installed on a clean,
properly resurfaced or brand new flywheel. Flywheels must be within original
equipment specifications. Centerforce clutches are designed to be used on
flywheels made of cast iron, steel, or aluminum with steel inserts.
Break-In : All Centerforce clutches require a break-in period of 450-500
miles of stopand-go street driving before applying full engine power. This
period is required to properly seat the disc with the pressure plate and
flywheel.
Balance: All Centerforce clutches are balanced from the factory to meet
or exceed Original Equipment (O.E.) specifications. Balancing with the
Centerforce weights installed on the clutch assembly may cause an out-of-
balance condition. Removing the weights without permission from Centerforce
may void the warranty.
Centrifugal Weight System: If your new Centerforce clutch is equipped
with the patented centrifugal weight system, do not remove the ring, weights,
or spring wire retaining the weight system to the diaphragm fingers. If your
Centerforce clutch does not include the centrifugal weight system, it is
because there is not sufficient clearance for Centerforce to safely &
effectively install the centrifugal weight system.
Aftermarket Hydraulic Release Bearings: When using an aftermarket
hydraulic release bearing it is important to check for proper clearance
between the bearing and the centrifugal weight system. Some aftermarket
hydraulic bearings have an antirotator pin that may come into contact with the
centrifugal weight system.
Failure to follow the above procedures will void your warranty and may result
in decreased performance and/or premature wear!
