project update

We have been racking our brains on how to lock the viscous coupling. There are a few ideas out there on how to make this possible but the expense is making it cost prohibitive. To make matters worse I don't know if the front output shaft is strong enough to handle being fully locked. But as the old saying goes when the going gets tough the tough get going. So we built a jig, welded the viscous coupling in the correct locked position and installed it in the transfer case.

By doing this we will be able to find out if the front output shaft is strong enough to handle the load put on it when the transfercase  is locked. If it doesn't explode we will continue to look for viable options to lock the T case. The best way to show that the transfer case is locked on a Borg-Warner box is to pull the front driveshaft and see if the truck will still move, and thats exactly what we did in this video.

Your first take on the video maybe just a yahoo having fun in the snow, but when you really look at it our  P38 is spinning the rear tires while the front tires remain stationary. This means the transfercase is locked and all the power is going to the rear output shaft without causing an explosion.  I'm pretty confident that the rear will hold up okay. We have been driving the truck around as a rearwheel drive unit for about a week without any side effects.
