[Shop-talk] Tool of the day

[old dirtbeard]

Hi guys,

I  bought a pair of these this winter primarily for use with cars, but I
really like the Zendex RakJak two bag air jack for use on the bikes as well.

In the attached link to a photo where I am removing and reinstalling the
rear wheel for my Sportster tire change, sliding the axle in through the
swing arm, the disk brake, the belt adjusters, etc., always is a little
tricky getting everything lined up height-wise while pushing the axle
through.

With the air jack, you can push the up/down buttons with one finger, raise
or lower the lift by small fractions of an inch, and eyeball the axle
alignment with the various components. The precision, smoothness, and
controllability of the lifting is pretty amazing:

They are US-made, support 2 tons each, very well built, very fast lifting,
good enough for professional shop use, all parts are replaceable, but they
are pricey.

If you were going to use it on trucks/vans/SUVs, I would recommend the
three bag model as it would give you more lift. The three bag model
probably would not fit under most sporty cars.

Definitely not a necessity (sort of like changing tires on the floor versus
the tire changer), but it makes jobs much easier with one man doing it, and
is much faster.

Downsides other than being pricey, they are a little wide and a little
heavy, and do not have the lifting range that a trolley floor jack would
have.

I mostly got them to do car wheel removals when the car is on the lift
(cannot use a floor jack), but have been using them instead of the floor
jack even on the floor because they are so fast and easy.

Clearly not a necessity, maybe an indulgent luxury, but my tool of the day.

Here is a video link from the manufacturer:
