sfsutton, I was curious so I check my 54 3100... From center just under 2 1/2 turns left to the bump, and just under 2 full turns to the right to the bump... What is up with the 1/2 turn difference? When I looked at OldSub Steering gear link and looked at the Turning Diameter chart, it shows "A" diameter range being Max 41-39 1/4 Min and "B" diameter range being Max 43 1/2-41 3/4 Min... This would explain the 1/2 turn difference...
