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 Patented 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.
Installation Instructions:
1. Apply oil to the pinion bearing bore and the pinion shaft journal including the splines.
2. Apply a liberal amount of 242 Loctite or similar brand to all threaded areas including the face of the nut and washer.
3. Tighten the pinion nut as typical during crush sleeve installation.
