INSTALLATION PROCEDURES - REVIEW COMPLETELY |
|
|
| 1 |
With the flywheel installed, make sure the stands
and shims are on the studs just as received. |
| 2 |
Install the bottom disc and support it with a clutch
alignment tool. |
| 3 |
Slide the floater plate onto the stands and install
the strap bolts. |
| 4 |
Make sure the strap holes align without forcing the
bolts in the holes, or the floater may bind |
| 5 |
Check the floater plate for freedom of movement and
that the straps slide freely on the retaining bolts without binding.
There should be no drag on the floater and the stand cutouts should be
centered on the stands. |
| 6 |
Remove the alignment tool and install the top disc,
reinserting the tool to align both discs. |
| 7 |
Install the cover in the marked clock position. Install the cover nuts and torque to proper specification
(30 ft/lbs steel stands, 25 ft/lbs composite
stands. Wiggling' the alignment tool top to bottom and side to side
as you initially tighten the cover will help keep the discs centered
properly. |
|
IMPORTANT! OVERTORQUING
THE COVER NUTS WILL DISTORT THE COMPOSITE STANDS AND CAUSE THEM TO
'SPREAD', WHICH WILL LOCK UP THE FLOATER PLATE
AND CAUSE NO RELEASE. |
| 8 |
Support
the transmission/torque tube so the input shaft slides into place.
Excessive rocking of the transmission WILL bend the discs and
cause non-release. |
|
|
|
PROBLEM SOLVING |
|
|
|
NO RELEASE OR CLUTCH DRAGGING, GRINDING WHEN
SHIFTING INTO GEARS |
|
GENERAL |
|
|
| 1 |
Insure that the cover clocking position is correct.
For the RTrack clutch Straps on the pressure plate should be staggered from the straps on
the floater plate. For the Force 10.5 and Force 9.5 they should be one
above the other. |
| 2 |
If
using composite stands, insure that the cover nuts are not overtorqued.
This can distort or 'bulge' the stands. |
| 3 |
Floater plate straps bent or binding on retaining
bolts. The floater plate must
move freely on these bolts before installing the cover. |
| 4 |
Clutch disc(s) bent or distorted from installing
transmission/torque tube. |
| 5 |
Release system travel may be inadequate.
See vehicle specific notes on this. |
| 6 |
If none of these situations are present, remove the
unit from the vehicle. Assemble
it on the bench and torque cover nuts to spec. Using
a press, check the release travel of the clutch levers (.400-.500").
At this travel point, you should be able to see light between the
top disc and the pressure ring, and you should be able to move the floater
plate up and down freely. |

VEHICLE SPECIFIC |
|
|
|
LSx EQUIPPED FACTORY HYDRAULIC RELEASE SYSTEMS |
|
|
| 1 |
Proper installed preload position of the hydraulic
release bearing is critical to clutch operation. |
| 2 |
For
front mounted transmission applications: |
|
Measure from the mounting face of the transmission
to the face of the release bearing in its extended position.
Write down this number 'a'. |
|
Measure from the bellhousing face (trans side) down
the the clutch fingers. Write
down this number 'b'. |
|
Subtract dimension 'b' from dimension 'a'. The difference is the pre-load position of the bearing.
Your target number is min. .500", max .700". |
| 3 |
For rear mounted transmission applications: |
|
Measure from the mounting face of the torque tube to
the face of the release bearing in its extended position.
Write down this number 'a'. |
|
Measure from the bellhousing face (trans side) down
the the clutch fingers. Write
down this number 'b'. |
|
Subtract dimension 'b' from dimension 'a'. The difference is the pre-load position of the bearing.
Your target number is min. .500", max .700". |
| 4 |
Check
condition of the hydraulic fluid. Is
it discolored or does it smell burned?
Discolored or smelly fluid indicates a heating of the hydraulic
lines possibly from headers or other undercar heat.
Properly insulate these lines, flush fluid, and replace. |

CABLE OPERATED FORD RELEASE SYSTEMS |
|
|
| 1 |
Proper setup height for the release fork is critical
to clutch operation. |
| 2 |
An adjustable pivot ball should be used to set this
height. (Lakewood pn 155502) |
| 3 |
Adjust the pivot position so that the fork and
bearing are positioned as close to the clutch assembly as possible,
without the fork hitting the cover. Make
sure you have a minimum of 1/4 inch bearing clearance with the fork at
rest. |
| 4 |
Cable
release mechanisms are prone to firewall flex in Mustangs.
Check for flex by having someone activate the clutch pedal while you
watch and feel the firewall for any movement. |
| 5 |
A high ramp rate quadrant is recommended for the RAM
Street Dual, such as UPR's triple hook model. |

MECHANICAL LINKAGE RELEASE SYSTEMS |
|
|
| 1 |
Proper setup height for the release fork is critical
to clutch operation. |
| 2 |
An adjustable pivot ball should be used to set this
height in GM applications. Pivot
point modifications may be required in Ford and Chrysler applications
to attain proper fork angle and release movement. |
| 3 |
Adjust the pivot position so that the fork and
bearing are positioned as close to the clutch assembly as possible,
without the fork hitting the cover. Make
sure you have a minimum of 1/4 inch bearing clearance with the fork at
rest. |
| 4 |
Fork angle affects release length and leverage. Vehicles with passenger side mounted fork pivots should
have a strong rearward angle when the bearing
is just touching the fingers; drivers side fork pivots should have a
strong forward angle when the bearing is touching. |
|
|
|
BENT OR BROKEN COVER OR FLOATER PLATE STRAPS |
|
|
| 1 |
Bent straps on the cover are an indication of
negative load on the clutch. This
can occur under heavy downshifting (without RPM matching) or
shifting into the wrong gear. |
| 2 |
Road racing conditions.
This clutch in its stock configuration is not designed for road
race. Improper downshifting
(without RPM matching) will bend or break
straps. RAM recommends
removing floater plate drive straps and installing all steel stands for
this type of use. |
| 3 |
Proper clutch life in road racing applications
demands good driver control. RPM's
MUST be matched on downshifts to avoid clutch damage. |
