Components of the bearing Installer / Remover Tool – the ASIR
1 NUT
2 BEARING PUSHER
3 LINER *
4 DRAW ROD
5 RECEIVER **
6 NUT (SAME AS ITEM 1)

Figure 1.

NOTE: Item #3 (liner)* is not being used in bearing removing and item #5 (receiver)** is not being used in bearing installation process.

BEARING REMOVING:

-Bearing outer race’s lip must be cut prior bearing removal.
-Use AeroStaking® bearing cutter to properly cut bearing swaged portion of the bearing without causing any damage to the housing’s bore.
-Bearing cutter will create round groove in external portion of the bearing outer race (7) as shown below:

NOTE: Liner (3) is not being used in bearing removal process.

CAUTION: As to avoid damage to the tool, remove bearing form the cut side to the uncut side (the cut side should be pushed in by the pusher).

-Disassemble the Installer / Remover Tool, one nut (1) can stay fastened to the draw rod (4) at shorter thread side.

-At the cut side of the bearing (7) set the draw rod (4) with pusher (2) so its angled, recessed surface will contact the bearing’s outer race (7) and its flat surface will contact the nut (1)

-Place receiver (5) onto the draw rod (4) on the opposite side of the bearing and situate it so the wide opening in receiver faces bearing’s un-cut side [see Figure 3.]

-Tighten the nut (6) finger-tight making sure pusher’s (2) flat surface is in full contact with the nut (1)

-Use proper size wrench to tighten the nut. if the opposite side nut starts spinning along lock it with another wrench

-Keep tightening until the bearing is being removed from mount fitting and placed inside the receiver (5) [see Figure 4.]

-Remove either nut, disassemble the tool and eradicate bearing from the draw rod
This completes bearing removing operation.

BEARING INSTALLATION:

NOTE: Receiver (5) is not being used in bearing installation process.

CAUTION: Damage to the mount fitting can occur if the outer race of the bearing is NOT aligned perpendicular with the bearing bore during bearing installation.

– Thread one nut (1) on the draw rod (4) [see Figure 5.]

– Place pusher (2) against the threaded nut (1) and set bearing onto the draw rod (4)

– Press bearing’s outer race firmly against the pusher. This will allow the bearing to self-align and square the races

Figure 5.

-Place liner (3) in the housing bore. Liner’s flanged side must be positioned inside the bore while its flat side faces the outside [see Figure 6.]

-Slide draw rod with bearing, pusher and nut from opposite side of the housing and through the hole of the liner.

-Ensure that bearing is properly seated against the mount (housing)

– Finger tighten nut (6) on the draw rod (4) against liner (3)

-Tighten nut (6) on the draw rod with proper wrench.
Use additional wrench if spinning occurs.
This will draw the bearing into the mount fitting bore.

– Tighten hex nut until bearing is seated against pilot flange of the liner [see Figure 7.]

NOTE: When the bearing is seated against the removal/installation tool pilot flange (3), about 1/16 in of the bearing race will protrude form the bearing bore on the opposite side.

-Remove hex nut and liner from the bore.

– Re-install the tool liner (3) with its flat face adjacent to the bearing [see Figure 8.]

– Thread on hex nut hand tight

– Using the proper wrench continue tightening the hex nut. This will result in drawing the bearing into the mount fitting bore until bearing is seated against flat face of liner, flush with mount fitting.

– Remove one hex nut to release the tool (ASIR) and its components.

This completes bearing installing operation.
