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. Please
see Understanding factory hydraulics.
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 pressure plate attachment nuts from the flywheel stand bolts (3/8”
12-point nuts). Notice the proper
orientation as noted above. 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 stands mounted to the flywheel with
straps, which are bolted in position. This
is how the floater should fit when installing the unit in the car.
Note: the pressure plate
stands each have shims on top of them. Be
sure they are in place when the unit is installed.
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/stands 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 over the stand bolts and torque the cover nuts to 30 ft/lbs, tightening them in a
star pattern so that the diaphragm is pulled down evenly.
Be sure the cover drive straps are aligned with the floater straps
and that each stand has its shims between the cover and the stand.
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.

IMPORTANT NOTICE
PROPER FLYWHEEL BOLT TORQUE IS
CRITICAL WHEN INSTALLING YOUR RAM STREET DUAL CLUTCH SYSTEM.
RAM STRONGLY RECOMMENDS AFTERMARKET FLYWHEEL BOLTS FOR YOUR APPLICATION.
7/16” BOLTS – 85 FT/LBS.
½” BOLTS – 135 FT/LBS.
10mm BOLTS – 65-70 FT/LBS.
11mm BOLTS – 80-85 FT/LBS.
USE A HIGH QUALITY AFTERMARKET
