Advance Adapters
If your T90 was originally fitted to a 4 cylinder, you will be required to purchase this 6 cylinder style input shaft, P/N 716014 (Jeep #906203). This shaft has a gear tooth count of 18 teeth. On some Jeep (and Scout) vehicles, the input shaft that you are replacing may be 16 tooth. This special tooth count is normally found only in a vehicle that has a 4:27 axle ratio. On these applications, you will also need to purchase a new cluster gear, P/N 716018. The best way to determine what your vehicle is equipped with is to simply remove the top cover and count the teeth on the front input shaft.
