RAM Force 9.5 clutch system

LS GM Applications PN 75-2100

Before installation

Proper release bearing preloading is essential to operation of this clutch. You MUST use the setup drawing located on the back of the quick start guide to check this before finishing the install.

An adjustable master cylinder is REQUIRED for installation of the RAM Street Dual. Part numbers are listed at the end of this instruction sheet.

The ‘drill modification’ MUST be performed for any LS application using the RAM Street Dual. Failure to perform this operation will result in premature slippage of the clutch system. There is an excellent tutorial on this at www.installuniversity.com. Click on ‘LSX vehicles’, then ‘install documents’.

LS hydraulic systems are extremely finicky. When installing the new hydraulics, it is ESSENTIAL to flush the system of old fluid and re-bleed with new fluid. Small particles in the fluid can clog the return port on the master cylinder and cause premature slippage of the clutch system.

Bleeding MUST be done by vacuum method or using a power bleeder such as a mity-vac.

Test fit both discs on the input shaft of the transmission. Make sure they slide freely on the splines.

If you are using an aftermarket bellhousing, it MUST be dial indicated to the engine before installing the clutch. These bellhousings typically are not centered and can cause release issues if not addressed.

Clutch installation

Remove the 6 pressure plate attachment bolts from the flywheel. Notice the proper orientation of the pressure plate on the flywheel. Be sure the unit is installed this way. Lift the cover from the flywheel. The top disc is a sprung hub configuration. After removing the sprung hub disc you will see the floater plate.

The floater plate drives off of the three straps mounted to the flywheel, which are bolted in position. This is how the floater should fit when installing the unit in the car.

Remove the three 5/16-18 capscrews and lift the floater plate out of the assembly. The solid hub bottom disc can now be removed.

Install the flywheel loctite or similar thread locker on the flywheel bolts. Torque the flywheel bolts to 75-85 ft/lbs.

Slip the top clutch disc (sprung hub disc) onto the clutch alignment shaft followed by the floater plate and bottom clutch disc (solid hub). Be sure the floater plate side that has the machined outer lip is facing the transmission (i.e. the completely flat side towards the flywheel).

Slide the clutch alignment tool into the pilot bushing while positioning the floater plate over the drive lugs. The three retaining straps should line up with the three 5/16-18 holes on the flywheel surface.

Install the three 5/16-18 capscrews through the strap into the flywheel (note: the straps should line up without any repositioning). Use a threadlocker on the capscrews.

At this point make sure the floater plate should have a slight gap between the friction surface and the bottom disc.

Place the pressure plate onto the flywheel and torque the cover bolts to 30 ft/lbs, tightening them in a star pattern so that the diaphragm is pulled down evenly.

The bellhousing and transmission can now be reinstalled. Be very careful not the let the transmission hang on the clutch disc spline during reassembly as this may bend the clutch disc carrier, which will cause release problems. THIS IS CRITICAL!

Adjustment

Mechanical & Cable linkages

Adjust your pivot ball to achieve a forward attitude (drivers side pivot) or rearward (pass. Side pivot) on the clutch fork when the bearing is just touching the fingers. Set the release low to the floor, maximum freeplay. If this is not comfortable then use a pedal stop to avoid excessive release.

LS1 hydraulic applications

RAM recommends using an adjustable master cylinder with this clutch assembly so you can limit the clutch travel and avoid shifting problems. Set the clutch pedal for minimum release, that is keep the pedal as low to the floor as possible.
