CJ750 Gearbox gets a new 3rd and 4th gear - Test-Adapter
05 October, 2024
To test the gearbox, the input shaft needs to be rotated. To connect the input shaft to a drill for example, an adapter is needed for the input spline.
I'm using an unused clutch for this.
Cut with a plasma cutter since some parts are hardened.
The cut out flange is machined using the input shaft.
To hold the flange with the spline in place, I'm using an old sidecar suspension holder.
The machined parts are secured with Loctite 638.
Finished spline adapter.
The gears gets installed with the dry gaskets only and checked if all gears can be selected and that they run without any grinding noise.
