INSTALLATION STEPS
Preparation
Preparation & Handling
Checklist
- What is the condition of the clutch being removed? Are there any signs of non-clutch (Hydraulics or Driveline misalignment) related issues that could have caused or lead to premature wear or failure?
- Is the hydraulic system properly functioning?
- When the old clutch is being removed are there oil leaks and any signs of red dust?
- Are cracks on the clutch release fork or excessive pivot ball wear?
- Are there any stretch signs on the clutch cable?
- Are the Hydraulic lines in good condition? Are they near heat sources and should be upgraded to braided lines in performance / modified applications?
- Any wearing on release bearing guide tube?
- Anything wrong with the spigot bearing or the pilot brush?
- What is the condition of the Flywheel? Does it have any run our or is the surface straight ?
- Any shipping damage on the clutch?
WHEN FITTING THE CLUTCH, MIND THE INPUT SHAFT SPLINES, CLUTCH SPLINE AND BELL HOUSING:
- Clean the gearbox main drive shaft splines and ensure that the clutch spline slides freely on the shaft.
- Ensure there is not excess play in the input shaft, if there is consider replacing gearbox input shaft bearing before proceeding with Clutch install
- Clean the bell housing: degrease, dust off and remove worn clutch fibres.
- LIGHTLY grease the shaft splines with high temperature grease. Using too much grease may contaminate the clutch plate/disc.
- When installing the gearbox ensure that the gearbox does not put any downward pressure on the clutch and spline in the UniClutch core. If this occurs it can damage the UniClutch spline assembly or put pressure on the circlips which can cause it to prematurely wear or pop out of the UniClutch assembly causing loss in drive.
DRIVELINE MISALIGNMENT
THE MOST COMMON CAUSES OF MISALIGNMENT ARE:
- Missing or damaged dowel pins allowing the transmission to be bolted off centre.
- Mislocated front bearing retainer.
- Foreign matter between the engine block and the transmission mounting faces.
- Missing or worn pilot bearing.
- Broken block flange.
WHAT ARE THE SYMPTOMS OF MISALIGNMENT?
- Pedal graunch with the engine running.
- Deterioration of the clutch until non-release occurs.
- Failed drive plate.
- Red dust covering clutch and/or groove worn in the diaphragm by the release bearing.
HOW DO I PREVENT MISALIGNMENT?
Whenever you are replacing a clutch, inspect the old components. If misalignment is present you will need to find the cause.
- Inspect all dowels and dowel holes for condition.
- Inspect release bearing guide and replace if necessary.
- Clean all mating surfaces.
- Inspect block flange for damage.
REMEMBER:
IF MISALIGNMENT IS PRESENT, FITTING A NEW CLUTCH KIT WILL NOT FIX THE CAUSE OF THE PROBLEM AND THE MISLIGNMENT WILL QUICKLY DESTROY THE NEW UNICLUTCH.
HOW TO CHECK FOR ENGINE/TRANMISSION MISALIGNMENT
STEP 1
Mount indicator to flywheel and determine concentricity of bell housing bore to centre line of crank rotation, SPECIFICATION: 0.015mm max, T.I.R.
STEP 2
With indicator still mounted to flywheel ensure rear surface of housing is square. SPECIFICATION: 0.15mm max, T.I.R.
REGISTER YOUR UNICLUTCH
CHECK IN TO YOUR NEW UNICLUTCH
Each UniClutch is 100% tested and marked with a unique QR code. Scan code on the base of the clutch to see the specifications of your unit, including manufacturing date.
INSTALLATION VIDEO
1. INSTALL SPLINE
A. CHOOSE AND TEST
Choose the correct spline for your vehicle. Test fit spline onto input shaft.
B. INSERT
Insert spline into UniClutch
C. Lock in Position
Insert circlip into clutch disc. Make sure circlip has fully expanded in clutch disc and is holding the spline securely before proceeding. Tap the circlip into place to ensure it is fully seated and secured.
ULTRA FLYWHEEL SPECIFIC FITMENT KITS
Only for Ultra Flywheel part numbers UCFW-001, UCFW-002, UCFW-003 & UCFW-004
2. ASSEMBLE UNICLUTCH & FLYWHEEL MOUNT
A. SPACERS
Install spacers in correct order. The spacers required for your application will be found in the vehicle specific installation guide. Measure the spacers to ensure you're using the correct spacer and or tapered bolts as arrange them as per the image on the vehicle specific installation guide.
B. BOLTS
You must add Loctite® 243™ or equivalent to all threaded bolts used with the UniClutch flex fit mounting system. Loctite®® 243™ does have a shelf life and if the bottle is old, has not been properly stored or exposed to air it is best to get a new bottle.
C. Torque Fitment kit Bolts
Then install supplied countersunk bolts to secure flywheel mount to UniClutch, torque to 22 Ft lbs / 30 Nm.
BOLTS ARE TORQUE TO YIELD, ONE USE ONLY. If you need another bolt kit, please contact us.
Use a properly maintained, correct-size hex head torque bit to tighten the bolts. Secure the UniClutch core firmly to torque the bolts to the Core and Flywheel mount.
3. IDENTIFY FLYWHEEL
A. Positive Step Flywheel
For vehicles fitted with positive step flywheels, please place washers (not included) between the flywheel mount and the flywheel to prevent excessive bending of the flywheel mount.
Where friction surface of the flywheel is on a higher level than the clutch bolting surface.
B. Without washer between the flywheel mount and the flywheel, UniClutch mounting tab is bent upwards, leading to improper installation.
A washer must be added in between the flywheel mount and the flywheel so the UniClutch mounting tab is not bent.
C. In some specific vehicle applications, the flywheel may require machining in order for the UniClutch to be fitted. This is only required in very limited Uniclutch fitments and will be specified in your specific install guide”.
4. BOLT TO FLYWHEEL
A. LOCATE
Locate the correct dowel holes for your vehicle. Download your Vehicle Specific Install Guide to get this.
B. FLYWHEEL
Match Flywheel Mount Dowel holes to vehicle flywheel dowels.
C. SECURE TO FLYWHEEL
Secure UniClutch to flywheel using existing clutch cover bolts and torque to OEM spec.
- Never use left over UniClutch fitment kit bolts or spacers to secure the flywheel mount to the flywheel.
- If you do not have the OEM clutch cover bolts then you will need to source an appropriate bolts. A12.9 grade cap head bolts are required and available everywhere.
- In modified engine, high RPM or race applications it is best practice to use Loctite 243 on the Flywheel to flywheel mount bolts , especially in applications that have be converted from a Dual mass flywheel to a solid flywheel.
- Engines that are know to have harmonic issues when modified should also observe the same practice as above.
5. FINAL ASSEMBLY
PLEASE NOTE
Whilst changing your clutch, you may wish to replace other worn items.
A. FLYWHEEL
Whilst UniClutch doesn't use the flywheel as a friction surface, you may wish to change your flywheel if it is damaged or out of balance.
B. BEARINGS
Replace any worn out bearings.
CI Release Bearing (Not provided)
CI Spigot Bearing/Bush (Not provided)
CI Release Bearing (Not provided)
CI Spigot Bearing/Bush (Not provided)
Replace any worn out bearings.
RELEASE BEARING/CSC
Use OEM style

SPIGOT BEARING/BUSH
Use OEM style
Use OEM style
OEM thrust bearing or Hydraulic release bearing / Concentric slave cylinder can be used with the UniClutch system in 99% of installations. Some installations may require a different bearing from OEM, and this will be specified in the specific installation guide for the individual vehicle.
In cases where the UniClutch is being used with an aftermarket or custom release bearing / hydraulic slave cylinder please ensure you contact UniClutch support to confirm suitability before use. Failure to do so may cause UniClutch to not function correct and damage the UniClutch.
Unless stated in the Fitment Kit Notes above, UniClutch suits OEM service parts.
The above Release Bearing or CSC and Spigot Bearing or Bush are references from Clutch Industries Australia. Equivalent OEM spec parts may be used.
C. TRANSMISSION INPUT SHAFT
Ensure Transmission Input Shaft is clean and lubricated very lightly using the grease included with your new UniClutch. Only use a small amount of grease as over greasing input shaft can lead to contamination of UniClutch friction plates when in operation.
Inspect and confirm that the gearbox input shaft end play is within the manufacturer’s tolerance. If end play exceeds tolerance, replace the input shaft bearing and any associated gearbox components before installing the UniClutch. This step is essential for applications where the input shaft is unsupported by a bearing or spigot in the flywheel. Failure to do the above may effect the functionality of the UniClutch and lead to premature failure which is not covered by warranty.
D. VEHICLE SPECIFIC TROUBLESHOOTING
Check if any vehicle specific troubleshooting notes apply. For example; concentric slave cylinder bleeding procedures, etc.
6. BEDDING IN PROCEDURE
This product is a specially engineered Clutch designed to offer an increase in torque capacity while still maintaining a level of drivability often not associated with products of this type. As a result you must ensure that the product is appropiately "broken-in" before heavy or spirited driving. The breaking-in process allows the friction surfaces to mate with each other in order to create full contact and allows the clutch to operate at its intended performance. During the initial bedding in phase, the co-efficient of friction of the clutch discs will drop, and then slowly increase over time to a stable level.
Failure to appropriately break-in clutch may result in glazing or crumbling of the friction surfaces resulting in shudder, slippage and noise during operation and not allow the clutch to transmit the torque to its maximum ability.
To correctly break-in your new UniClutch we recommend operation the vehicle in normal driving conditions such as regular city driving. The clutch must be actuated regularly at low RPM such as take-off and normal shifting for at least the first 500kms. During breakin if the vehicle RPM increases at a rate not proportionate with the normal rotation of the wheels you must back off the throttle to ensure you do not not generate excessive heat. Excessive heat will prevent UniClutch from reaching its full potential.
