Before
installation
For
05-up applications, proper release bearing preloading is essential to operation
of this clutch due to the hydraulic release mechanism.
You MUST use the setup drawing located on the back of the quick start
guide to check this before finishing the install. See Understanding
factory hydraulics.
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.
For 01-04 Mustang
applications, it may be necessary to trim the input collar ½ inch to allow the
transmission to fully install into the bellhousing without contacting the clutch
disc.
For Mustangs utilizing a
T-56 transmission with an aftermarket 26 spline input shaft, you must check to
insure you have complete spline engagement on the bottom disc.
Some older retrofit inputs have shorter splines and may not properly
engage the bottom disc.
IMPORTANT
TECHNICAL NOTE:
The
2010 GT500 uses a different slave release bearing and clutch than the 06-09
models. This one is shorter and has maximum travel of .880”. In
order for our dual disc built at 3.300 – 3.400 to work with this car, the
customer must install a 1/2 inch bearing spacer to achieve .530-.550 bearing
preload. Without it there is NO preload and the bearing will damage itself
if the install and bleed is attempted without verifying measurements.
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.
Pivot Balls/Brackets/Release Bearings
An adjustable pivot ball
should be used with all 5.0/5.8L applications to achieve the proper fork angles
described above. 4.6L applications
should use Lakewood pivot ball 15502.
Small and Big Block Late model apps (passenger side pivot) require
release bearing 501, early model apps (drivers side pivot) should use release
bearing 485.
Other
modifications
RAM STRONGLY ADVISES THE
USE OF A SAFETY BELLHOUSING WITH THE RAM STREET DUAL.
If you have enough power to need a dual disc, you need this safety
device!
When
using a safety bellhousing, be sure to follow the manufacturers instructions for
proper bellhousing alignment.
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
BOLT SET AND RED LOCTITE ON THE THREADS. GO
THROUGH THE TORQUE SEQUENCE 3 TIMES.
