Tech Note 1: Mainshaft Specs
QU10214 is a 4x4 23 spline mainshaft with a full length 5th gear spline.
QU10214 Specifications and Approximate Dimensions:
Overall Length: 17-1/2"
Output Spline: 23
3-4 Synchro Hub Spline: 1.45" x 28
1-2 Synchro Hub Spline: 3.365" x 20
Reverse Cluch Spline: 2.285" x 45
Fifth Gear Spline: 1.59" diameter x 1-7/8" long by 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.
Tech Note 3: Tech Articles
For more information about NV4500 5th gear failures, see:
5th Gear Failures and Solutions
NV4500 Cast Iron Tailshaft Housings
We no longer make the Torque King® Mainshaft and Retrofit Kits as described in the 5th Gear Failures and Solutions, article which leaves full spline shafts the only choice currently available for Dodge NV4500HD transmissions. While full spline shafts do not actually cure the 5th gear issue, they do greatly reduce the chances of the nut backing off.
