The original alloy vernier timing gear set has been re-designed. The complete cam sprocket assembly is now machined from 7075 aerospace aluminium with extra lightening by the way of large arched slots in the sprocket. It's finished with 7075 aluminium clamping washers.
The crankshaft sprocket is CNC machined from steel and now comes with an extra deep keyway and a full radius machined into the rear of the bore (only applies to MED product). This eases fitment to EN40B steel crankshafts that have no undercut machined into the rear of the sprocket mounting diameter.
This setup will fit all standard A-Series crankshafts without modification.
The timing gear set comes as standard with:
- IWIS high quality timing chain
- Allen countersink screws for the engine plate
- Allen cap screws and spring washers to mount the camshaft triangle
