So in pulling the chain, it pushes the tongue against the ball via
where I say the pawl is. That then creates the same lever arm most all other WD systems look like.
Then the TV pulls and the ball wants to go towards the coupler front
(away from the pawl). Then does the ball bang back and forth inside
the coupler?
Hi Ben,
I hear what you are saying but are you missing that the hitch shank is in the truck and the TT and TV connection is sagging way down with no WD yet applied. When you pull on the chains the bottom of the tow ball shank goes toward the TT and the hitch shank hanging out of the back of the truck starts to pivot in the receiver torque tube. AS teh chain force increases by crank the tension nut the top of the tow ball goes towards the truck.
EDIT: 1-15-12 See page 4. Ben is correct. The point I missed was the TT can roll forward and then the TT is pulled up against the ball coupler latch. Be back soon
