I dislike the feeling of trasmition windup all flanders seem to have, now i know that some is normal but i still dont like it, i have had a good look at makeing a dog clutch, it could be done but would be expencive. i have however been thinking about a free wheel on the rear prop shaft, i can get a sprag bearing and it should be easy for me to turn up a housing and shorten the shaft, by about 40mm. this would give 4x4 forwards only when the front sliped but i would lose 4x4 in reverse, i think this would be ok, it would also be ok to fit only two new tyres at a time, what do you all think?
