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 mechanic.

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 when 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 (661) 940-7555 or email tech@advancedclutch.com.

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 discussed below, 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:

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 any sign of cracks. Any of these potential issues must be addressed before installing your new ACT clutch.
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 re-surfaced 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.
Clean the flywheel and pressure plate surfaces with solvent or detergent. Clutch slippage or chatter can be caused by a dirty or oily surface.

ACT PRESSURE PLATE INSTALLATION INSTRUCTIONS

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):

Lightly grease the splines of the disc and slide the new disc on the input shaft to insure 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.

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:

7mm x 1.0	15 ftlbs / 20Nm
8mm x 1.0	25 ftlbs / 34Nm
8mm x 1.25	26 ftlbs / 35Nm
10mm x 1.25	50 ftlbs / 68Nm
10mm x 1.5	50 ftlbs / 68Nm

5/16 x 18	29 ftlbs / 39Nm
5/16 x 24	29 ftlbs / 39Nm
3/8 x 16	45 ftlbs / 61Nm
3/8 x 24	48 ftlbs / 65Nm

If you choose factory standard bolts and are unsure of the grade of fastener, use the factory recommended torque values.

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.
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.
Adjust the clutch release system by following the vehicle manufacturer’s procedures and specifications. Recommended break in for ACT Street Discs is 200-300 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.

FLYWHEEL INSTALLATION INSTRUCTIONS

Inspect the flywheel packaging to be sure it is the correct flywheel for your application. Verify that all dowels are in place and that the SFI Certification sticker and serial number are on the part. Any modifications to the flywheel will void the SFI Certification and warranty.
Install a new pilot bearing into the flywheel if required; this should be pressed in for proper fitment.
Line up the flywheel to the hole pattern and install new factory flywheel bolts using thread locking compound for extra assurance. For some applications, bolts are provided. Always consult the factory service manual for proper torque specifications. For racing applications, consider high strength ARP (or similar) fasteners when available. Consult your bolt supplier or expert engine builder for recommended torque specifications.
Replace clutch components using ACT pressure plate installation instructions.

TECHNICAL INFO

Racing
ACT certifies many of their clutches to SFI specifications for racing purposes (check product packaging and product to determine if your product is SFI certified). For your safety, always operate within recommended RPM limits set by the automobile manufacturer, do not overheat the clutch, and conform to all rules set by the sanctioning organization. For high RPM applications a bell housing scatter shield should always be used to minimize chances of personal injury.

Due to the hazardous nature of racing ACT accepts no responsibility of any kind for clutches used for racing applications. ACT only certifies that certain parts conform to SFI specifications.
Release Point Adjustment - Hydraulic System
On some applications the engagement point may be closer to the floor. For most applications the engagement point is adjustable and a small adjustment of the clutch master cylinder push rod will cure the problem. This adjustment is made by screwing the push rod farther into the master cylinder to allow it to actuate the cylinder sooner. Never preload the master cylinder. You may also desire to increase pedal travel by adjusting the pedal stop (when equipped). Most repair manuals include instructions and adjustment specifications. Aftermarket clutch pedals, floor mats or carpet may hinder full pedal travel and may affect the proper performance of the clutch.
Flywheel Resurfacing
Flywheel resurfacing should only be performed by a professional using the proper machinery. A smooth and flat flywheel surface is critical to proper clutch operation and longevity. It is extremely important to maintain the proper step in the flywheel. Re-balancing the flywheel following resurfacing is also recommended. Maintaining balance of the flywheel will insure that the engine will stay smooth and can reach high RPM without damage to the engine.
