To add the new ring gear to the Tiger lightened flywheel the former was put in a hot oven and the latter in the freezer. Once fitted the ring gear was held in place with weights until both had returned to room temperature.
Comparing old (Focus) and new lightened (Pinto) flywheels. On the scales the Focus weighs in at 9.8kg and the Pinto at 5.8kg. Hopefully this will give a good performance boost in terms of acceleration, along with a more responsive throttle response.
The flywheel bolts were shortened so that the same amount of thread (15mm) showed through the rear of the flywheel as in the original Focus installation (the lightened Pinto flywheel is thinner - no prizes there). All good so far. However, the edges of the bolts clash with the tapered edge of the flywheel. Also the socket fouls on the flywheel.
Plan B was to use another, original length, set of flywheel bolts and use washers as spacers. Two washers were needed for each bolt to compensate for the thickness of metal removed from the flywheel. The washers nearest the flywheel needed filing down (from 5mm to 3mm) on one edge. Okay, the edge was not there until I filed it!
Flywheel bolts installed with thread lock. Each was marked to show that it had been torqued up to the correct value. In the centre is the spigot bearing fitted. Pushed in just flush with the outer edge. It would've gone in further, but here it should provide maximum support for the gearbox input shaft.
Fitting the clutch using an old borrowed gearbox input shaft as a centring tool (Thanks Pete). This made it very easy to get the perfect alignment of the clutch plate.
