Installation instructions for the RAM C4 clutch conversion system

Your new clutch assembly is bolted together the same way it will install in the car. Note the position and hub orientation of the clutch disc as you disassemble the unit for installation.

Install the flywheel using a thread sealant on the bolts and torque to 85 ft/lbs. Wipe the flywheel surface clean with a soft rag and non-oily solvent.

The pressure plate should be bolted in place using hand tools to avoid distorting the cover. Tighten in a star pattern until snug and torque to 30-35 ft/lbs. Be sure to use an alignment tool in the clutch disc for easy installation of the transmission and to avoid bending the disc on install.

HYDRAULIC SLAVE CYLINDER

ZR-1 / LT-5 INSTALLATION Conversion Package #900820 and #900830

Test fit the slave cylinder assembly on the release bearing sleeve and position the slave housing so that the hydraulic lines are pointed to the original slave cylinder opening in the bellhousing. Remove the transmission retainer plate bolt that aligns with the guide slot in the housing and install the guide stud in its place.

With the flywheel and clutch installed, put the bellhousing in place and secure it against the block with two bolts. Measure the distance from the transmission mounting surface to the tip of one of the clutch fingers with a vernier caliper. Record this measurement.

Install the slave cylinder onto the transmission collar making sure the bearing and housing are retracted as far as possible and that the base is sitting on the retainer plate.

Accurately measure the distance from the contact face of the bearing down to the mounting surface of the transmission. Record this measurement.

Subtract the bearing face to transmission measurement from the bellhousing to finger measurement. You should have 0.135" to 0.200". This is the required bearing to finger clearance when the transmission is in place.

With the bellhousing still in place, select an accessible spot on the passenger side of the bellhousing to hole saw a 1-¼ " access hole in order to align the slave cylinder with the guide pin when installing the transmission. You will do this with a long screwdriver. After mating the guide stud with the alignment slot in the slave housing, insert the screwdriver between the clutch fingers and bearing face to seat the slave against the retainer plate and check for adequate clearance between the bearing and clutch fingers.

Complete the bellhousing installation with the slave supported with a dowel through the input shaft hole into the disc. Support the slave by hand and remove the dowel. Start the transmission input shaft through the slave and work the slave onto the transmission collar (Using the access hole and long screwdriver) as you complete insertion of the transmission. After bolting the transmission to the bellhousing, do the screwdriver procedure described above making sure the hydraulic lines are exiting through the original slave cylinder opening in the bellhousing.

Connect the hydraulic feed line from the master cylinder using the supplied adapters, then fill bleed the system.

At this point you should check for proper clutch release. Insert the driveshaft into the transmission. Put the transmission into the 1:1 gear. (High. Not overdrive.) Depress the clutch pedal and make sure the driveshaft turns freely.

Complete the reassembly process.

LT-1 & L98 INSTALLATION Conversion Package #900800 and #900810

Slide the slave cylinder assembly onto the release bearing sleeve and position the slave housing so that the hydraulic lines are pointed to the original slave cylinder opening in the bellhousing. Note the transmission retainer plate bolt that aligns with the guide slot in the housing. Note the retainer plate bolt that sits directly under hydraulic connections on the slave body.

Remove the transmission retainer plate. Countersink the plate hole for the bolt that sits under the hydraulic connections to accept the flat head socket screw supplied. Make sure the head is flush or slightly below the plate surface. Replace the retainer plate using this screw. Replace the bolt that aligns with the guide slot with the guide stud. (Note: The pin does not clamp the plate to the transmission housing.)

Slide the slave assembly onto the release bearing sleeve and make sure the slave housing sits down flush with the retainer plate.

With the flywheel and clutch installed, put the bellhousing in place and secure against the block with two bolts. Measure the distance from the transmission mounting surface to the tip of one of the clutch fingers with a vernier caliper. Record this measurement.

Install the slave cylinder onto the transmission collar making sure the bearing and housing are retracted as far as possible and that the base is sitting on the retainer plate.

Accurately measure the distance from the contact face of the bearing down to the mounting surface of the transmission. Record this measurement.

After mating the guide pin with the alignment slot in the slave housing, insert the screwdriver between the clutch fingers and bearing face to seat the slave against the retainer plate and check for adequate clearance between the bearing and clutch fingers.

Complete the bellhousing installation with the slave supported with a dowel through the pilot hole into the disc. Support the slave by hand and remove the dowel. Start the transmission input shaft through the slave and work the slave onto the transmission collar as you complete insertion of the transmission. After bolting the transmission to the bellhousing, do the screwdriver procedure described above making sure the hydraulic lines are exiting through the original slave cylinder opening in the bellhousing.

Connect the hydraulic feed line from the master cylinder and. bleed the system.

Complete the reassembly process.
