The old problematic flat toothed timing belt is replaced with the latest HTD ‘High Torque Drive’ motorsport round tooth form belt for ultimate reliability.
Both crankshaft and camshaft pulleys are of a new design complete with fully adjustable vernier cam pulley. The crankshaft pulley now has a larger outside diameter to retain rigidity along the key way and resist cracks.
The main housing is CNC machined from billet alloy and has internal breather holes drilled to relieve crankcase pressure helping to prevent oil leaks in this area.
Another enhancement is the large diameter idler tensioner which runs on a pair of sealed bearings, this allows the belt to be tensioned to allow for the backlash in the belt to be removed – giving perfect cam timing on and off the throttle.
A mounting boss is also machined into the main housing and a pipe adaptor is supplied for a breather connection.
The main housing now incorporates the original steel engine plate as part of the housing further reducing weight.
The front covers are radially split and stepped to enable access to camshaft timing without removal of the crankshaft pulley.
Mounting holes for the pickup bracket for use with engine management are drilled and tapped. **bracket and pickup not included**
