Due to the extra rollers it can make it more difficult to fit starter hub in and easy to derail the springs, so we advise before fitting to the flywheel that all the springs and roller are sitting correctly, the lower the flywheel on to the clutch and then flip over to bolt on the clutch. Remove the plastic insert and fit the hub into the clutch by turning anti clock till it drops in, they you can fit it onto the crankshaft.
Worth carrying out the above to prevent the springs coming out and derailing the rollers.
