Tech Note 1: Specs and Dims
QU10098 is a 4x4 32 spline mainshaft.
QU10098 Specifications and Approximate Dimensions:
Overall Length: 19-3/4"
Output Spline: 32
3-4 Synchro Hub Spline: 1.45" x 28
1-2 Synchro Hub Spline: 3.365" x 20
Reverse Clutch Spline: 2.285" x 45
Fifth Gear Spline: 1.59" diameter x 31 spline
Tech Note 2: Not a Press Fit
There is currently no available NV4500 mainshaft from any supplier that will have a press fit for the 3-4 synchro, mainshaft 5th gear, or the rear output bearing. They are specifically designed and machined this way to speed assembly. The only shafts that had a press fit were the original equipment New Venture shafts and our Torque King shafts, both of which are long out of production and no longer available.
