guzzi trike project

This is what I have so far.The differential is from  2002 can am quest 650 atv.The trouble is when I rotate the right tire the left tire does not move but I can spin it myself.When I lock the right tire and try to turn the input pinion it takes about 40 ft pounds and the left wheel still does not move. I think it has a visco lock  system but I know little about atv's. I bought the diff on ebay from a salvage yard. He knows even less than me. Any help? thanks

It is the FRONT diff.I have done research but found no answer .It has a viscous automatic locker. I really don't know how it works though .

Before you commit to a locking diff, you might want to read up on the advantages/disadvantages of the style.  My research steered me away from limited slip and locking IRS diffs.

It appears to be the type that only works as one wheel is slipping, the difference in wheel speed then progressively pumps fluid to a clutch pack that will then drive the non slipping wheel.  It would seem the system would only work by driving the input shaft. To test it I am guessing you would lock either wheel and then drive the input shaft until the unlocked wheel spins enough to engage the clutch pack and tries to spin the locked wheel.  It should be an open differential until the clutch pack engages from the wheel speed difference.  Mike
