re:cleavers
If you have not run one on an Allison, you are missing a sweet running wheel. Totally different in feel, less torque than a round ear wheel, and I was able to run the cleaver high enough to loose water pressure with out hint of blowout. They feel like pivot point back there versus a normal feeling with any other type of wheel, kinda hard to explain. I ran one light, never with a load.
