Illustration 1. Installation of tools for bearing removal.
Illustration 2. Dimensions to fabricate plates.It is necessary to make two spacer blocks for the removal of the bearings. These spacer blocks can be fabricated from steel according to Illustration 3. The spacer blocks can be used in different positions for different applications.
Illustration 3. Dimensions to fabricate blocks.If the part number for the bearing is not in the chart, you can use the dimensions that follow to make a puller plate:
1. The diameter of the hole in the center of the plate is 25.4 mm (1.00").2. Diameter A is 1.5 mm (.06") smaller than the diameter of the "bore" of the bearing to be removed.3. Diameter B is 1.5 mm to 3.0 mm (.06" to .12") larger than the outside diameter of the "ball".4. Diameter C is 1.5 mm to 3.0 mm (.06" to .12") smaller than the outside diameter of the outside race.5. Diameter D is 19.0 to 28.4 mm (.75" to 1.12").6. Dimension E is 0.8 mm (.03") more than the distance that the "ball" extends beyond the outside of the bearing race.7. Dimension F must be small enough to permit diameter A to be used as a pilot (guide) in the bore of the ball.The other tools needed for removal or installation of the bearings are: 1P820 Hydraulic Puller Group, 2J3507 Nut, 3K5234 Washer, and a hydraulic pump.
