TECH TIPS

Although designed for minimum response for the most in advanced play...
Dif-e-Yo's can be set up for more response if needed.

Bearing care and maintenance.
CAUTION
If you use bearings completely dry without lube they can eventually get damaged.
Run them dry at your own Risk!!

Bearings need to be Cleaned and Lubed over time and extended use.
This applies to ceramic bearings as well.
If you're serious about cleaning your bearings I recommend investing in a Sonic Cleaner.
Short of that, here's more info on cleaning and bearing  care.

When using Solvents and Compressed air, use all... Safety Precautions ...
associated with Chemicals and use Safety Glasses when using Compressed air.
If you're not sure of what to do, ... find out!
Better safe than Sorry! If you have questions let me know.

Shields need to be removed to clean the bearing properly.
This will help insure foreign particles do not remain in the bearing.
Once I received a bearing back from a customer having a problem
and after opening the bearing found a 3 inch long strand of hair inside
and the bearing simply needed to be cleaned.
Even with the shields on, dirt and string lint can get into a bearing.
Remove the shields and clean the bearing in a solvent such as paint thinner or grease remover such as Gunk .... Engine Degreaser... found in any auto supply store.
There are other solvents that can be used to clean bearings but... some solvents
evaporate too fast and leave dry residue in the bearing that
cause the bearing not to spin freely after cleaning. It may spin free at first but,
can then become responsive and possibly lock up!
Regardless of how you clean a bearing I Highly Recommend using some type of lube
after cleaning the bearing before using it.

Once the bearing has been cleaned it's recommended using compressed air to blow and spin dry the bearing which also helps to remove any particles that may still be in the bearing.
It's also best to put some light oil lube in the bearing after cleaning and before using air to spin it clean.

If you want the bearing to be Unresponsive it should still have some light oil in it.

To Lube the bearings for Unresponsive play.. Ceramic or otherwise.
I recommend Thin YoYo Jam oil and only enough so it's not dry.
A tiny drop of oil worked into the balls inside will be keep it from locking up
and still allow it to spin without affecting the response.

Put some oil on the end of a toothpick or pin.. not even enough so it looks like a drop...
just so it is wet from the oil. Then keep touching it to the balls in the bearing and spin the bearing with your fingers to work it in.
If you put too much it will dissipate the more you play and get unresponsive.

I do NOT recommend using a dremel on a bearing!
If there is any dirt etc. in the bearing when it is used on the dremel...
the particles will be ground up and can get impregnated into the bearing.

Dif-e-Yo's respond best with Slick 6 string.
With any yoyo.. a Fresh string is always best
and don't let it get too tight.
Let the yoyo hang and untwist the string every so often and you'll see a difference in play until it gets twisted tight again.
100% Cotton string is stiffer and will not create as much response.
If you do Not want  more response... 100% Cotton works well but...
with the variety of new types of string available now you may find a different string
suits your play better, so experiment to find a string that works best for you.


Lubing a bearing will increase response considerably and is the most effective method.
Brain Lube is the recommended Lube if you desire more response!
Though some spin time will be lost you will find with the KonKave bearing
it's not enough to hinder play and the yoyo will still be smooth playing and return easier.

Other options for more response are .030" thick Dif-Pads
offered  as an "option" to the original .015 thick Dif-pads for Dif-e-Yo yoyos.
For Maximum Response...  precut Duncan Friction stickers work well.

Dif-Pad Installation

Using the "tip" of a thin knife , X-acto blade or even a toothpick , ..
 put the edge of the Dif-Pad on the tip of the tool your using.
 Place the pad over the yoyo and eyeball how it lines up before pressing it on.
 The Dif-Pads won't stick solid until you press hard and with this in mind, ..
 lay the pad gently onto the yoyo until it is lined up.
 Then press the whole pad with your thumb to seat it and then remove the tool.
 Also before pressing  hard to seat it totally... you can push from the center hole outward while working your way around which will slightly stretch and move the inner hole away from the bearing a little more and then press it solid.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The following axle info does not apply to the Tank model.
The axle in the Tank is self centering and does not aid in aligning the halves.

Info on the axle in a Dif-e-Yo yoyo:
Do "Not" screw the axle tight into one side of the yoyo.
It's designed to align the yoyo halves by ..
being loose in both halves, before tightening the yoyo together.
Tightening the axle into one side before tightening the yoyo itself can cause the axle to be crooked in that halve of the yoyo and can possibly cause the yoyo to wobble.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Tightening the YoYo
It is somewhat inherent for Aluminum fixed gap yo's to come loose if not tight enough. With the Dif-e-Yo Heavy duty axle the yoyo can be tightened quite a bit without damage. After you put the yoyo together all the way.... With the yoyo set between the palm of your hands flat open .. press your hands together like you're trying to squash the yoyo and at the same time tighten it until the yoyo starts slipping in your palms. You should find it will not come apart until you're ready to take it apart. If you find it hard to get apart.. do the same thing with your open palms only in reverse. If you have more questions just let me know.

Looking for Smooth play with less response and
a response system that lasts.
Dif-Pads
They play like half worn friction stickers right from the start
and stay that way. Will fit any yoyo that uses Friction stickers.
Don't know how long they last because the one's in use have not
worn out yet after weeks of testing. After extended play the Dif-Pads will
seem like they have no response at all and what you will find is the pads are ok
and that it's the string that needs to be replaced to get some response again.
"Response varies in different yoyo's."
2 Dif-Pads are needed for Dif-e-Yo yoyos and Lube helps if you want more.
Yoyo's with more inner wall area offer "more" response with the
Dif-Pads but are still
extremely Smooth and have not shown any signs of wear yet either.
You might only need one Dif-Pad in these yoyo's to get the response you like.
Experience the Dif-ference.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Dif-Pads

It's a personal preference as to how long you want to leave the Dif-Pads on
as to how thin they get after prolonged use.
If you go by how the yoyo is working compared to what the pads look like,
that is usually why or when you might want to change them.

The pads are the same material all the way through.
There are Not any layers of different material even though they
look different on the surface when new.
They look that way because of the manufacturing process where the outer skin cured.
The response properties are pretty much the same throughout the life of the pads and..
Most of the reason the response lessens isn't so much the pad material itself but the fact that they get thin or worn in a particular area where the string makes the most contact.
