Gears & Shafts
The gear tooth design has been optimized for gearbox smoothness and efficiency. The fine tooth design allows more teeth to be in mesh with each other at any moment. There will be three teeth in mesh as opposed to two in conventional gearboxes. This greatly reduces gear noise.
The input shaft incorporates fixed 1st, 2nd, 3rd and 4th speed input gears forming a single component. Fifth gear is splined to the input shaft and secured with a lock nut. The output shaft assembly contains all free rotating output gears and synchronizer assemblies.
The differential is mounted on two tapered roller bearings. The need to take preload measurements is negated by the use of very close machining tolerances on the various components. This accuracy is achieved with a new machining technique that employs the very latest technological advances. Automated machines take temperature readings from the aluminum block being machined, the cutting head and cutting fluid and make necessary adjustments to compensate for temperature fluctuations.
