Ron,
1/4" is a lot of free play. I have a very worn "spare" that only has
1/8". Something is wrong. A good one would have more like 1/32". Why
not ask Pro-Gear? I certainly would not run it in that condition. If you
run it all summer, the gears will be worn in a pattern that will be
screwed up forever.
