Have you experienced leaking bearing retainers or bearing failure with your Tri-5?

The original design is weak and as it becomes bent and distorted it allows the bearing to move back and forth within the housing. The bearings are to be held in place by the retainer plates. O-rings are not designed to move; they are designed to provide a seal between two non-moving parts. Eventually, this movement will cause damage the o-ring seal, bearing, or both.

This on the right is an OEM bearing retainer removed from a 1955 Chevrolet Bel Air. It is bent, distorted and had been damaged when someone used a torch to assist with removal during a previous service.


These bearing and retainer problems prompted Tri-5 WeeCrafted to design these new, stronger CNC machined bearing retainer plates.
