Warning Symbols
How can you reduce the risk of personal injury to yourself or others and ensure the proper performance
of your new clutch? Answers to such questions are contained in comments highlighted by the warning
triangle symbol. These comments should be read and observed. Failure to do so may lead to serious injury,
death or clutch failure.
Failure to follow the vehicle manufacturer’s installation procedures and specifications
as the primary source of information and ACT’s installation instructions as a secondary source may
lead to serious injury, death or clutch failure. Installation should only be performed by an experienced,
knowledgeable technician.
This is a high performance product. With the additional performance gained from this product, you may
experience additional wear or potential failure to the other vehicle components, such as (but not limited to)
tire wear, twisted axles or input shaft, broken transmission or differential gears and even pedal assembly
or engagement system damage.
Failure to properly install and utilize ACT’s performance products in conformance with the
vehicle manufacturer’s and ACT’s instructions may cause loss of vehicle control, damage or possible bodily
injury or death. Always operate your vehicle within the performance guidelines of the vehicle manufacturer
and in conformance with the instructions set forth in the owner’s manual. It is your responsibility as the
vehicle owner and modifier to ensure that all components are in proper working condition and maintained in
conformance with the vehicle manufacturer’s instructions to handle the increase in performance.
Always ensure components are correct for the proposed application prior to installation.
Consult your ACT catalog or supplier, as installing a clutch to the wrong application will void the warranty
and may lead to loss of vehicle control, damage or possible bodily injury or death.
The new clutch components may look different from the previous parts produced from another
manufacturer. Pressure plate must fit on locating dowels, where applicable, for proper centering. Rotating
pressure plate may be necessary to line up offset dowels. Slide disc on transmission shaft to ensure proper
fit onto input shaft. Verify correct fit of release bearing and pilot bearing (if applicable). Any modifications to
the pressure plate or disc will void the SFI Certification and warranty. If there are any further questions, call
our tech line at [phone] or email [e-mail].
Prior to installation, a thorough inspection of the existing clutch and operating system must be performed.
If you are unable to determine the condition of the old clutch and operating system or are unable to confirm
the absence of any of the issues discuss, seek professional advice and inspection prior to installing a new
clutch. Failure to do so may void the warranty and may lead to possible damage or bodily injury or death.
Recognizing that every vehicle and clutch design is different, the inspection of the existing clutch and
operating system will vary and should include, but is not limited to, the following:
1. Check hydraulic system, bearing free travel, clutch cable, oil leaks, rear main seal and transmission seal.
Inspect releaser guide tube, release fork, pivot stud and cross-shaft bushings for wear. Inspect the flywheel
for cracks. Any of these potential issues must be corrected before installing a new ACT clutch.
2. Inspect friction face of the flywheel to ensure it is in working condition. If abnormal wear, or deformation
by heat is found, the flywheel must be replaced or resurfaced to avoid malfunction. However, flywheel
resurfacing should only be performed by a professional. Use proper step height when resurfacing flywheel
as this is critical to the function of the clutch. Pressure plate locating dowels must be properly installed.
To avoid the potential for catastrophic failure, replace flywheel if any cracks are present.
3. Clean the flywheel and pressure plate surfaces with solvent or detergent. Clutch slippage or chatter can
be caused by a dirty or oily surface.
Once the inspection is complete and you have determined that there are no issues or problems with the
existing clutch or operating system, installation of the new clutch can be accomplished as follows (note:
every vehicle and clutch design is different and may vary):
1. Lightly grease the splines of the disc and slide the new disc on the input shaft to ensure fit and smooth
travel, and wipe off any excess grease. Replace pilot bearing/bushing, and apply a light coat of motor oil to
bushings, or high temperature bearing grease to needle-type bearings.
2. Use an alignment tool to center the disc against the flywheel. Manually tighten pressure plate bolts using
a star or diagonal pattern. ACT recommends using metric grade 10.9 (SAE grade 8) or stronger fasteners.
The use of high temperature thread-locking compound is recommended for performance applications.
Tightening torque specifications will vary with bolt size and grade. The following torque specifications are
recommended by ACT for new pressure plate bolts with the corresponding sizes using metric grade 10.9
or SAE grade 8 bolts:
If you choose factory standard bolts and are unsure of the grade of fastener, use the factory recommended
torque values.
3. Lightly lubricate the release bearing inside diameter and the mating surfaces between the fork and
releaser. Lubricate the clutch linkage as recommended by the vehicle manufacturer.
4. Make sure all bellhousing dowels are in correct position and tighten bellhousing bolts.
Any misalignment will result in premature clutch failure. Correctly support the transmission during
installation. Neglecting to do so may cause clutch damage and premature failure.
5. Adjust the clutch release system by following the vehicle manufacturer’s procedures and specifications.
Recommended break-in for ACT Street discs is 300-500 miles of mild street driving. Avoid driving habits
that would allow excessive slipping or overheating of the clutch.
Failure to properly break-in the ACT Street discs may result in clutch damage and
premature failure.
