The Tilton Press-Fit Outer Race piston design holds the outer race of the contact bearing, allowing the inner race to rotate. The piston should be warmed in an oven while chilling the bearing to relax the press fit for installation. This piston fits 300, 400, 600, and 800-series Tilton hydraulic release bearings. 0.850" (21.6mm) total height; 0.835" engagement. This is the same piston supplied in our Tilton Hydraulic Release Bearing for Van Diemen Formula Ford (Part No. 163-53).
This piston does not work with press-fit bearings held by the inner race (such as our 52mm Radius-Face Bearing, Part No. 163-60).
The Tilton HRB Contact Bearing and Tilton HRB Seal Kit (Part No. 163-61) are sold separately.
