Product Usage Instructions

Pre-Verto Flywheel Installation:

1. Gently lap the flywheel to the crankshaft taper with a suitable paste.
2. Remove all traces of lapping paste.
3. Refit the flywheel and tighten the F/W bolt, ensuring correct fitment of the keyed washer.
4. Lock the engine in position with a Mini flywheel locking tool or similar.
5. Torque the flywheel bolt to 120lb/ft, to fully seat the flywheel on the crankshaft.
6. Undo the bolt, apply a drop of 2701 Loctite (or similar) to the thread, and re-torque to 120lb/ft.

Verto (including SPi/MPi) Flywheel Installation

3. Refit the flywheel and tighten the F/W bolt, ensuring correct fitment of the keyed washer.
4. Lock the engine in position with a Mini flywheel locking tool or similar.
5. Torque the flywheel bolt to 120lb/ft, to fully seat the flywheel on the crankshaft.
6. Undo the bolt, apply a drop of 2701 Loctite (or similar) to the thread, and re-torque to 120lb/ft.

Bedding-in Procedure

Our clutch plate manufacturer recommends that all clutches should be carefully bedded in for 200 miles to achieve the maximum torque-holding ability. This does not include motorway driving or rolling road testing.
To bed the clutch into the flywheel and back plate, it will need to be submitted to some gentle heat cycles and stop-start traffic. This will ensure full contact with the friction faces.

This package has been expertly assembled, and balanced to within 1 gram on our special balancing rig. We recommend leaving the assembly as one complete unit rather than stripping it down and trying to reassemble in situ, as this is likely to affect the balance. Ideally, during an engine rebuild, we would recommend having the crankshaft and damper balanced to a similar tolerance to retain the overall balance. We usually suggest balancing all components individually, so that any changes in the future will not cause a problem. Where budget allows, you could go one step further and re-balance the damper and flywheel with your specific crankshaft, but for most, this will be a bit excessive.
We find that many customers install these kits to an engine in situ, and in this case, bolting the flywheel assembly on complete will get you as close as possible to a good overall balance.
If you wish to gently lap the flywheel to the crankshaft taper before fitment, this is still possible by following the recommended installation steps below. These tips will greatly reduce the chances of the bolt working loose and/or the flywheel fretting on the crankshaft

Pre-Verto Flywheel Installation

1. Remove the release bearing thrust plate and wire clip from the clutch diaphragm.
2. Gently lap the flywheel to the crankshaft taper with a suitable paste.
3. Remove all traces of lapping paste.
4. Refit the flywheel and tighten the F/W bolt, ensuring correct fitment of the keyed washer.
5. Lock the engine in position with a Mini flywheel locking tool or similar.
6. Torque the MED pre-Verto flywheel bolt to 130lb/ft, to fully seat the flywheel on the crankshaft.
7. Undo the bolt, apply a drop of 2701 Loctite (or similar) to the thread, and re-torque to 130lb/ft.
8. Refit the release bearing thrust plate and wire clip to the diaphragm.
