Product Usage Instructions

1. Unpack all of the Clutch Kit components and thoroughly clean all parts supplied using lacquer thinner or brake cleaner that does not leave a residue.
2. Check that the clutch discs slide freely on the transmission input shaft.
3. If using F9014 flywheels, thread the bolts into the flywheel before assembling the clutch.
4. Bolt the Flywheel to the engine crankshaft with the supplied bolts. Use suitable Loctite (Loctite 272) on the threads and tighten to the manufacturer’s specification.
5. Mount the clutch disc with the side marked “Flywheel Side” against the flywheel and insert an alignment tool through the clutch disc spline.
6. Assemble the intermediate plate onto the drive blocks, ensuring that the spring clips are handled with care as they are factory set for release. Remove the foam packing just before installation. Make sure the heads of the bolts are still in the groove on the back of the flywheel.
7. Mount the Clutch Disc with the Pressure Plate Side against the Cover or Pressure Ring.
8. Slide the Cover Assembly over the clutch mounting bolts, ensuring that the drive blocks are sitting in the groove of the Flywheel and Cover Assembly, and that all of the heads of the bolts are still in the groove on the back of the flywheel. Ensure that blocks do not ride up on the step on the Flywheel or Cover during assembly.
9. To check bearing compression on a one-piece bell housing and transmission:
   1. Measure Distance A from the engine block to the flat on the clutch cover.
   2. Subtract Distance B from A. This (D) is the Finger height in relation to the block.
   3. Measure distance C from the Engine Block Flange to the face of the bearing on CSC (leave the CSC extended, just as it sits).
   4. Distance C must be .500-.725 less than D. If not, contact Mantic Clutch USA for further assistance.

7. Assemble the intermediate plate onto the drive blocks as shown. Note: Care must be taken when handling the intermediate plate spring clips as they are factory set for release. If they are damaged in any way the clutch may not operate as designed. The Foam Packing must be removed just before installation. Make sure the heads of the bolts are still in the groove on the back of the flywheel.
8. Mount the Clutch Disc with the “Pressure Plate Side” against the Cover or Pressure Ring.
9. Slide the Cover Assembly over the clutch mounting bolts and make sure the Drive blocks are sitting in the groove of the Flywheel and Cover Assembly and that all of the heads of the bolts are still in the groove on the back of the flywheel.
   Ensure Blocks do not ride up on the step on the Flywheel or Cover during assembly
10. Place the supplied lock washers (failure to use the supplied lock washers may result in the nuts working loose and the clutch failing) and nuts over the clutch mounting bolts and tighten each by hand, until the heads have seated correctly in the groove on the back of the flywheel. Ensure the drive blocks have seated correctly on the Flywheel and Cover, (i.e. not sitting up on the machined step that positions the drive blocks).
    Tighten each nut one half a turn at a time, always tightening the nut diagonally opposite the previously tightened nut. The final torque for the nuts is 25 ft-lbs ( 33Nm ). When the nuts are tightened the fingers of the diaphragm should now be even. (No variation of the heights of each diaphragm finger). If there is variation of over 1mm the cover has not been fitted correctly and should be loosened and checked as per the procedure above.

To check bearing compression on a one piece bell housing and transmission

Measure Distance A from the engine block to the flat on the clutch cover
