Systems and methods for preloading a bearing and aligning a lock nut
A system for use in providing a load on a bearing mounted to a shaft includes a preload apparatus having a first extension and a second extension engageable with an inner race of the bearing and configured to provide a compressive load to the bearing. The first extension has a first projection and the second extension has a second projection. A stop ring is configured to limit a radially inward movement of the first extension and the second extension toward each other to position the first projection and the second projection relative to the bearing.
HEAVY DUTY EXPANDABLE BEARING PULLER
In an embodiment of the disclosed principles, a bearing extraction tool is provided having a threaded rod, an expansion sleeve over a portion of the threaded rod and a multi-segment expansion head between the expansion sleeve and a bottom end of the threaded rod. The threaded rod bottom end includes an expansion plug having a ramped shoulder, a trunk and a stop. The expansion sleeve includes a ramped shoulder facing the ramped shoulder of the expansion plug. The outermost diameter of the expansion head occurs at a ledge portion of the expansion head. The ledge portion is small enough to fit through the central opening of a bearing to be extracted. When the two shoulders are then pushed towards one another, the ramped shoulders expand the expansion head, locking the ledge portion behind the bearing. Subsequent outward movement of the tool via a threaded fitting on the threaded rod moves the bearing outward for extraction.

Sleeve-component extracting jig
A sleeve-component extracting jig according to the present invention is configured to include an engagement part on which a thread engageable with an inner circumferential surface of a sleeve component is formed, wherein a taper surface configured by cutting off crests of the thread to lower a height of the thread toward a leading end of the engagement part, and a plurality of clearance grooves open at the leading end of the engagement part and arranged at equal angular intervals in a circumferential direction of the engagement part are formed in the engagement part, a length of a radius of the engagement part at an end position of the taper surface is a sum of a length obtained by multiplying a thickness of the sleeve component by a digging ratio (20%˜60%) and a length of an inside radius of the inner circumferential surface of the sleeve component.

Method and assembly for extracting press fit bushings
An assembly for removing a bushing is provided including a mandrel having a size and shape similar to the bushing and a receiver having a hollow interior cavity. A fastener extends through an opening formed in both the mandrel and the receiver. A socket attachment has a first opening configured to removably couple to a first end of the fastener and a second opening configured to removably couple to a torque delivery tool. A biasing mechanism arranged adjacent a second end of the fastener is configured to generate a biasing force to drive the mandrel against a bushing in response to a coupling of the socket attachment and the fastener.
Puller spacer
A puller spacer has a cylindrical and elongated body. The puller spacer has a slot formed in a side of the body. The slot extends from a center bore of the puller spacer to an exterior of the puller spacer. Wires that extend out of a steering column are routed through a bottom of the puller spacer and into a center bore of the puller spacer, with an end of each of the wires extending out of the slot formed in a side of the puller spacer. The puller spacer is positioned between a distal end of a center threaded member of a steering wheel puller and the top of the steering column. The steering wheel puller engages the steering wheel and the center threaded member of the steering wheel puller is advanced to pull the steering wheel away from the steering column.
LOWER CONTROL ARM DECOMMISSIONING DEVICE
A lower control arm decommissioning device is provided. The lower control arm decommissioning device includes a tabletop, a fixture operable to hold a lower control arm in a fixed position relative to the tabletop, and two opposing bushing removal tools configured for pushing simultaneously on two bushings of the lower control arm and displacing the two bushings from the lower control arm.
Industrial fan bushing replacement tool
A bushing installation tool having a plurality of spacer rods with first and second ends and a pressure plate mounted to the first ends of the spacer rods. A first base includes portions configured to engage an end of a cylindrical bushing and to restrain radial expansion of a cylindrical bushing received. The bushing installation tool has a first stage in which the first base being releasably engage with the second ends of the spacer rods. A second base including portions configured to engage the end of the cylindrical bushing and to permit radial expansion of the cylindrical bushing engaged therewith. The second base also including portions configured to releasably engage the second ends of the spacer rods and being alternatively interchangeable with the first base. The bushing installation tool includes a second stage in which the second base is releasably engaged with the second ends of the spacer rods.
