Whats the part number for the bearing needed to complete a 32 spline input shaft conversion on a NP246 transfer case? I have the shaft but can't get a good answer on the bearing needed.

Thanks!

I've been looking here:
NP 246 : , Cobra Transmission


Inner input bearing:
NP 246, Input Bearing (Inner) [411240] - $11.99 : , Cobra Transmission


Input bearing:
NP 246, Input Bearing [CT-325287] - $10.99 : , Cobra Transmission


I just can't tell if the inner (1st) or input (2nd) bearing is different for the 32 spline input shaft vs 27 spline. Arg!

I measured the OD of the 32 spline shaft. It was 50mm where the bearing (2nd) would fit. I think that a 27 spline input shaft would have a smaller OD because of the fewer splines. I'm guessing the needed part is thus the (2nd) link.

I'll order both to be safe and will post back exactly what part is needed.

I'm about to be in the same boat. What p/n was the right one?

Hold on. I'll try and dig up the part number from when I ordered mine.

You should be able to google "input bearing .630 wide np246" and find what you need.

Make sure to use anaerobic sealer on that t case, not just silicone gasket maker

^^ I think you got it right. I ordered both bearings and forgot the # of the one that worked.

Its the same bearing that goes into the stock 27 spine input shaft.
