After all the fasteners are removed - Allen head screws, etc, the wheel
can be laid on it side and at the point where the wheel head and shaft
join, several shots of PB Blaster should be applied. Leave overnight,
try next day to pry off.

When I removed my Shimpo RK-2 wheel head in order to fit a one-piece
splash pan, I used an inclined plane. Here's from a 2009 post:
"The original splash pan was an ingenious two-piece plastic affair
that included an nice shelf on the far side of the
wheel. Unfortunately over the years it kinda crystallized or
something and just fell to pieces. I was able to find a decent
one-piece pan from Laguna for about $35 several years ago. But the
one-piece design means having to remove the wheel head for
installation, and that was on very tight after 30 years. I fashioned
a long sort of chisel to lift the head off from its bearing (insert,
tap, tap, turn wheel, repeat...)."
First, of course, remove the retaining bolt that fastens the head to the sh=

Remind your friend that prying is a really good way to warp the head. Try =
flipping it over and have the wheel body suspended securely on 2x4's restin=
g on chair seats or table tops=3D2C saw horses...etc. Then shoot some WD-40=
=3D2C brake fluid=3D2C or panther piss (if you can buy the modern version) =
the area you wish to loosen.
As it soaks in=3D2C sharply tap the outer rim of the head with a wooden Mal=
t(not steel) on several opposing places along the perimeter. Tapping (not p=
ounding) sets up a vibration that helps the loosening agent penetrate=3D2C =
d breaks up the oxidation grime and or ionization transfer that has caused =
an interface between the metal parts.
Cut a long wooden wedge from a 2x 0r 1x4 to then tap between the wheel body=
and the "Boss" of the wheel head center. Avoid putting pressure on the hea=
d rim.=3DA0 Once you have induced pressure from your wedge=3D2C you may tap=
rim a bit more if it remains stuck.
All else fails: get a bigger hammer and say some really "bad" words=3D3B or=

Especially as more and more we are encouraged to join "one more" Cyber site=

My RK has this problem. While I've not yet been able to get the wheelhead=
here is what Shimpo told me to try...
"Before releasing the wheelhead make sure you have removed the bolt that =
bellow it utilizing the T-Wrench. WD-40 should help you release it, but i=
not enough you can try to carefully pry it with a couple of 2x4's. Try to=
two so that it comes straight up. If you use just one you can risk bendin=
wheelhead. Also be careful not to force anything and cause damage to your=
wheel or yourself.=3D20
If you feel comfortable doing this, the other option is to get your wheel=
at a very slow speed and then try to hold the wheelhead. This will help i=
release from the shaft.=3D20
The RK-Whisper usually comes with a manual. If you would like us to send =
one just email me your address.=3D20
Hope that helps!"

A trick used by aviation mechanics and auto mechanics is to apply the
"200 taps" principle. Tap the side - the boss - of the wheel head where
it attaches to the shaft. Tap, turn, tap, turn, go round and round and
round - 200 taps. And I mean taps - not hits or strikes. The vibration
should break the grip of the wheel head on the shaft. Before you start -
be sure the connection is soaked with a good penetrating oil - PB
Blaster or Marvels Mystery Oil or similar. Let it soak over night - then

Over the years I've had to remove various stubborn and well-seized-on wheel=
My technique is as follows:
Remove all locking screws/pinch bolts.=3D20
If possible lock the shaft so that the wheel won't turn.=3D20
Place a rough circle of firebrick round the rim, then direct a strong flame=
rom a large gas torch at the centre. When it changes colour A LITTLE, not r=
d heat (Aluminium will start to go yellow-ish). Then, wearing thick Kiln gl=
ves, grasp the rim and give it a sharp twist. It should move after that tre=
tment, as in heating up the wheelhead, you will have caused it to expand ju=
t enough to break the "seal".=3D20
