The ALT Drift


Removes the First Bearing in a BSB Configuration*

The ALT Drift is designed as an inexpensive way to remove the first bearing in a BSB configuration*. It is an alternative to a punch & hammer or a blind bearing puller.

When trying to remove the first bearing in a BSB configuration, the bearing spacer between the bearings impedes your access to the back side of the bearing. This lack of access will keep you from using a standard bearing press to remove the bearing.

Use the ALT Drift instead of the ALT Extractor when you only need to remove the bearing in a couple of BSB configurations where:

  • The bearing spacer moves off to the side by at least 1mm

  • The bearing spacer is at least 10mm long.

Note: if you expect to use the ALT Drift on unknown BSB removals in the future, consider the ALT Extractor instead. It doesn’t have any requirements for the bearing spacer and can remove double stacked pivot bearings. You’ll likely run into these restrictions if you’re a shop.

* BSB - Bearing/Spacer/Bearing


IMPORTANT

The ALT Drift Kit is currently in beta testing and will be sold at an introductory price to get some real-world home mechanic testing. And it would be nice to get some feedback!

Only consider this kit if you’re willing to follow the instructions.


Sizes:

The ALT Drift fits these sizes of bearing inner diameter (ID):

15, 17, 18, 20, 25mm

Features:

The ALT Drift works with a controllable screwing motion. No hammering or yanking.

Solidly presses against the bearing inner ring.

Made of anodized aluminum.

Comes on a foam stand to keep all the parts organized.


Requirements:

  1. The bearing spacer needs to be able to move off it’s axis by at least 1mm.

  2. The bearing press needs a flat, perpendicular and large enough surface to leverage the ALT Drift.


How it works

This tool removes the first bearing using the screwing motion of a bearing press in a controlled and confident manner.

The ALT Drift uses the same principal as a punch. After moving the internal bearing spacer off it’s axis, a punch presses against the exposed inner ring of the bearing. The mechanic then alternates the sides of the bearing that the force is applied to press the bearing out “straight-ish”

Same goes for the ALT Drift which presses against the exposed inner ring of the bearing and then, thanks to the screwing motion, varies the force applied to the bearing inner ring as it rotates until the bearing pops out.

ALT Drift Kits

The ALT Drift comes in two kit versions.

Model: ALTD-1

ALTD-1 kit contains the ALT Drifts and the ALT rod, but needs to be used with:

  1. HSBP-1 Hub & Suspension kit for hub, freehub & suspension tasks.

  2. Suspension bearing press for suspension tasks.

Model: ALTD-2

ALTD-2 is a totally stand alone kit which CONTAINS ALL THE PARTS that you’ll need to remove the first bearing in a BSB configuration for hubs, free hubs and suspension. This kit is for those of you who already have other bearing presses.
