INSTALLATION STEPS
Preparation
Preparation & Handling
Checklist
- 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?
- Any wearing on release bearing guide tube?
- Anything wrong with the spigot bearing or the pilot brush?
- Any shipping damage on the clutch?
WHEN FITTING THE CLUTCH, MIND THE SHAFT SPLINES, CLUTCH DISK AND BELL HOUSING:
- Clean the gearbox main drive shaft splines and ensure that the clutch disc slides freely on the shaft.
- 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.
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.
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.

Warning:
Failure to comply with the bedding in procedure will void the warranty of your UniClutch.
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
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.
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.
B. BOLTS
You must add Loctite® 243™ to the countersunk flywheel mount bolts.
C. TIGHTEN 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.
3. 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.
4. FINAL ASSEMBLY
PLEASE NOTE
Whilst changing your clutch, you may wish to replace other worn items.
