Looks like 1:2.31 (13:30). I'm not sure if you have the 6 or 3 jaw reverse gear L/U, but they both have the same ratios anyway.<br /><br /> 6 jaw vs 3 jaw<br />Info came from GLM Catalog. Among other places.<br /><br />PS - I've been thinking 'Big Hammer' for almost a week now. I guess I give up...
