This is an excellent observation Simon, I had noticed that the bits on the the
small gear on the differential were similar to that on the 16 tooth idler
gears, but had never actually put 2 and 2 together and come up with the idea of
using the claw clutch with it! I can think of a lot of applications for your
idea here - getting the pneumatic elements to move the claw clutch, thereby
creating an air activated diff lock could be one...
Not that I want to be pedantic, but I think what you have proposed actually
makes a differential lock as opposed to a limited slip differential, as the
latter actually allows some difference between the speeds of the two output
axles, whereas putting the claw clutch into the diff will totally lock them
together. There is an excellent implementation of a limited slip differential

Thanks for the tip,
