Fully torque one bearing-cap bolt on each cap, while snugging down theother. Turn the adjusters in until there is a small amount of preload.At the same time, keep a noticeable amount of backlash in the gears. Youcan feel the adjuster tighten and remove any bearing play. Starting witha large amount of backlash, turn the left adjuster (opposite side of thegear teeth) as tight as you can, pulling on a 12-inch long spannerwrench. Tighten the right-side adjuster to make sure it's tight, andthen measure the backlash. Randy's Ring and Pinion recommends .006-.010inch of final backlash, easily checked with a dial indicator. Backlashshould be checked at four different positions by rotating the ring andpinion. If the backlash is too wide, back the right (ring-tooth side)adjuster off a notch, and then bring the left back in to full preload.Again, wrench the right adjuster to make sure it's tight, and recheck.Work the ring gear toward the pinion in this manner until the backlashis within specs. Once the backlash is set, torque the remaining main-capbolt on each cap.
