Using the manufacturer s clutch assembly part number to match up a replacement clutch will help ensure that a correct replacement clutch assembly is selected. If you do not see a manufacturer s part number listed in our catalog or the truck in question has an engine that was rerated to put out more torque than stock, please call us to help ensure a correct replacement clutch assembly is selected.

3 CLUTCH ASSEMBLIES Self-Adjusting AutoSet Clutch The patented AutoSet Clutch by Illinois Auto Truck Co., Inc. improves on all previously available versions of self-adjusting Heavy Duty clutches. With every push of the clutch pedal, clutches and the associated parts wear over time. s AutoSet Clutch compensates for wear by auto-adjusting to maintain the clutch pedal freeplay ( 1 / 2 distance between the release bearing and the clutch brake). As an increase in wear occurs the release bearing moves closer to the clutch brake. The AutoSet Clutch incorporates two shifting cams that sense the time to adjust to maintain proper clearance. The external indicator tab provides a visual inspection of the remaining available clutch life. The AutoSet Clutch sets itself upon installation and eliminates necessary manual adjustments throughout the life of the clutch. The AutoSet Clutch is the perfect solution to decrease clutch maintenance costs and maximize vehicle operation time.

5 CLUTCH ASSEMBLIES Heavy Duty SOFT PEDAL SOFT PEDAL clutches have state-of-the-art diaphragm spring technology resulting in smoother engagement. Clutches incorporate the still popular manual adjustment feature. Drive strap design provides a smoother transfer of energy and avoids the internal friction causing metal wear. Improved heat dissipation is achieved through enlarged cover ventilation. The 30% pedal effort reduction resulting from the diaphragm design lowers driver fatigue. Clutch covers and discs are not shown to scale.

14 CLUTCH PARTS Quality Replacement Clutch Components When to Use an Oversized Clutch Brake or Brake Washer Every clutch replacement requires flywheel resurfacing. The use of ceramic friction materials requires more material be removed in the resurfacing process. This results in the clutch assembly being moved closer to the engine and away from the transmission. Pre-adjustment of the clutch to compensate for a larger clutch envelope results in diminished adjustment during the life of the clutch and can even cause malfunction within the clutch assembly.

Then select the corresponding clutch brake (hinged or torque limiting) and/or washer from the charts at right.

22 TECHNICAL INFORMATION FLYWHEEL CLEARANCE Opening Opening Opening 8 DISC SPRINGS 10 DISC SPRINGS 6, 7 & 9 DISC SPRINGS CLUTCH ENVELOPE Illinois Auto Truck Co., Inc. refers to the distance between the flywheel and front bearing cap as the clutch envelope. This distance becomes larger over time due to flywheel and front bearing cap wear. In this instance, initial clutch adjustment can cause premature failure and decrease the life of the clutch. Therefore instead of adjusting the clutch install an oversize clutch brake to compensate for the oversized clutch envelope. Refer to page 14 for more information. CLUTCH SYSTEM SETTINGS *Ensure there is at least 5/16 clearance between the top of the flywheel mounting bolt head & the flywheel surface to prevent interference. If there is less than 5/16 clearance replace the flywheel.

23 TECHNICAL INFORMATION QUICK TROUBLESHOOTING GUIDE CLUTCH SLIPPING PROBABLE CAUSE No free pedal. Release mechanism is binding. Worn clutch facings. Grease or oil on facings. Weak pressure springs. Overload clutch. CORRECTION Re-adjust per instructions included with each NEW clutch assembly. Check entire release mechanism & linkage. Replace all worn or modified parts and lubricate if necessary. Install a NEW clutch assembly. Install NEW disc(s) if organic friction material is used; find and repair cause of grease or oil contamination. Install a NEW clutch assembly that is correctly specified for the vehicle. Check to assure that proper clutch has been specified. NOISY CLUTCH PROBABLE CAUSE Clutch release bearing dry or damaged. Flywheel pilot bearing dry or damaged. Gear rattle present during engine idle. Cross member of yoke / fork is contacting clutch cover. Rear disc (pressure plate side) rivets are interfering with retainer hub. Improper clearance between drive slots and drive lugs on intermediate plate. CORRECTION Lubricate bearings with high temperature grease or install NEW clutch assembly. Replace flywheel pilot bearing. Verify that the correct clutch is selected for the vehicle. Raise engine RPM to possibly eliminate noise. Adjust the clutch. Check wear on cross shafts, bell housing bushings and release yoke / fork. Replace where necessary. Adjust clutch properly so that release bearing travels a minimum of 1 / 2 and that a 1 / 8 gap is set between the fork tips and bearing pads with clutch pedal up. Clearance should be no less than (.006 ). POOR CLUTCH RELEASE PROBABLE CAUSE Clutch adjustment not correct. Disc(s) is/are installed backwards or the flywheel opening is too small for disc damper OD. Damaged sleeve bushing. Damaged or bent disc assembly. Damaged clutch release bearing from lack of proper lubrication. Cross-shaft protruding through release yoke / fork clearance hole. Release yoke / fork cross piece is contacting clutch assembly at full release position. Release yoke / fork not aligned properly with release bearing. Intermediate plate sticking on the drive lugs (14 Cast AS 2-plate assemblies only). Pressure plate not retracting. Worn Splines on the input shaft. Damaged clutch brake or release bearing not in contact with clutch brake. CORRECTION Recheck adjustment per instructions. Check disc(s) labels & install per directions. Check existing flywheel opening ID vs. disc damper OD. Install a NEW clutch assembly or NEW cover assembly if applicable. Replace disc(s) assembly. Install a NEW clutch assembly or NEW cover assembly if applicable. Realign cross-shaft so that it does not protrude. Check linkage adjustment. Replace linkage or release yoke / fork. Check the flywheel. Most likely too much material has been removed from the flywheel. Check that the drive pins are 90 degrees square to the flywheel surface & that there is a min. (.006 ) clearance between the drive pins and the intermediate plate slots. Verify the installation blocks are removed during installation and not lodged in the cover during operation. Replace input shaft. Adjust clutch so that release bearing contacts clutch brake with pedal completely depressed. Replace damaged clutch brake.
