Actually there is a difference. There is a cone gear directly below the yoke that is affected by the direction of rotation. When the vehicle is turning the driveshaft to supply power to the wheels, the force tends to keep that gear in place. With the wheels providing the power to rotate the differential, the forces are redirected. I have found that there is less wear when the yoke is spinning counterclockwise (from above). Spinning the other direction there is a tendency for the cone gear to come loose and loose a few teeth by jamming with the other gears.
To reverse the direction is not quite as bad as driving in reverse, but you do need to turn the axle around and put your tongue on the other side to get proper rotation.
DISCLAIMER- YMMV and many people have had success with tow mixers without paying any attention whatsoever to the rotation direction. I'm just passing on my experience, I can't pass on the sound that crunching gears make as they are destroying the insides of a differential.

Have my pond almost complete. I am putting the finishing touches on my camptrailerfor over by the pond. So life is good and the tow mixer fabrication has moved back up the list to maybe third spot. I rolled the frame outof myshed this morning to get at my table saw and noticed that thedifferentialwas rotating clockwise when I pulled it out. This set off somealarm bellssince it seems to me I read somewhere it should be going counterclockwisefor longest life? Can anyone confirm that for me? If I need tochange itdoing so at this stage will be much easier than later. Thanx in advance Nick ,_._,___Hi Nick The differential is operating normally . When the drive shaft turns it cause the bevel or ring gear to turn and it reverses the dirrection to turn the axles. When a car is being pulled the wheels roll in the opposite direction of when it is powered by the drive shaft. If the wheels rolled forward the trailer would pass the tow vehicle which could be messy. :} The only way to change direction is to drive in reverse. If you can back a short trailer for a mile at 5 miles an hour I will come watch for cars for you . :} Just kidding. The odds of wearing out a differential in any vehicle is low even with hundreds of thousands of miles on them ,they are very reliable mechanisms. It may last longer that way as most of the wear on the device already is from rotating in the other direction. I have no way of estimating the stress mixing papercrete puts on it but at the slow speeds and slow acceleration you will use it at if it is in decent shape now you can count on at least 30k more miles in a worst case scenario that is a lot of papercrete and if you wear the differential out after all that you can afford to rebuild it. Keep it lubed with 90 weight gear oil and worry about something else. ------------------------------------ Yahoo!
