Pinion Setting Tool Instructions

This tool is designed to work with aftermarket gears that have the checking distance marked on the pinion head. It does not work with oem. gears which do not contain the checking distance info.

• 1. Clean and remove any burrs or paint from the top of the pinion head.
• 2. Mount the head bearing on to the pinion shaft and install in the housing without the pinion seal or crushsleeve. Tighten the pinion nut enough to take up the slack in the bearings.
• 3. Place the pinion setting tool on top of the pinion head with the slot end of the tool in the carrier bearing journal. (fig. 3,4,5) The end of the tool will rest against the end of axle tube surface.
• 4. With the tool being held by your left hand firmly against the top of the pinion head and the slotted end touching the face of the axle tube, insert the dial caliper with your right hand into the slot and position the depth rod so it touches the bottom of the carrier bearing journal. (fig. 6)
• 5. Take the measurement from the dial caliper and subtract it from the dimension printed on the tool. The answer is the current checking distance of the pinion gear. Add the appropriate amount of shims to arrive at the number marked on the end of the pinion gear by the manufacturer.

Current Crush Sleeve design

• Purpose of the item is to maintain pressure between two tapered roller bearings located on a common shaft to prevent position change of the bearings and fastener during operation.
• During installation the bulge will compress as the bearing center distance is decreased thus applying thrust pressure to both bearings and fastener.
• The current industry design has three bending or compression points of the bulge area. (A)
• Installation characteristics are an initial high thrust pressure for approximately the first .010 of length change of the spacer then thrust pressure drops approximately 20%.
• Typical required fastener torque to compress the spacer is approximately 300-400 ft. lbs.
• The usable compression distance is .040-.060 in length.
• Cycle duty is poor.

New Patent Pending Smart Sleeve design

• The bulge area is restricted to two areas with the majority of the deformation taking place on the flat of the bulge. (B)
• Installation characteristics are a consistent thrust pressure for the entire length change of the spacer.
• Typical required fastener torque to compress the spacer is approximately half of the current design. (130-150 ft.lbs.)
• The usable compression distance is .095 in length.
• Cycle duty is better than a solid spacer and shim pack.
