Head bearings on the ZX9R-C1

So I need to replace the head bearing's on the ZX9R. I thought it was a
bit weird going into corners. The new tires have highlighted this. So
armed with new bearings and a garage full of tools one wonders how one
would support such a motorcycle with the front end removed. So I ask the
experts for suggestions please.

 

Axle stand or block under the sump/lower frame rails [1], but tie the
rear wheel to the ground or weight the rear at least. Lock the centre
stand if it's got a hole in it to do that.

A garage, you say? Loop of rope round a roof beam to the top frame rail.

[1] If you have them on that.

My dealership hangs the bike from a ceiling beam.

 

AHA, That's what I've done on the past. So I guess it's the suspend from
beam trick.

I wouldn't, unless your garage roof beams are substantially stronger
than mine. Remember that you may end up getting medieval on the old
bearings to get them out...

The axle stands under the frame rails approach would be my first choice.

Does a 9R have proper frame rails?

Oh. Good point. It might not.

Sky hook. That's what he needs.

If you suspend a frame by a rope and then get medeival on it to try to
push the bearings out there's no fucking way they are going to shift;
the rope will take up the slack.

He'll need something hard under the headstock unless there's a press or
something that will draw the bearings out. Looks like a good excuse to
buy tools to me.

Good point. Up until the garage roof collapses, anyway.

Indeed, indeed. Or to make them. I made a very nice gadget to press the
new bearings into my ZZR a couple of years back.

I ssupended my ZX9 by ratchet straps from a nurses lift and knocked the
old bearings out with a long drift and a 2lb hammer. It wasn't
difficult, but helped by the fact that the ZX9 headstock has two purpose
built slots to put a drift into that extend the full height of the
headstock. There's none of this fuckling around trying to stop the drift
from slipping off the edge of the bearing, every hit counts. From start
to finish it took about 3 1/2 hours of me working alone to do the job.

I use a plastic faced dead blow hammer and get them square before
whacking hard.

No subtlety, some Spics...

Be advised a Special Tool exists (and is easily adapted to other sizes).

Will it fit Bandit 600s?

Give me five minutes and it will.

Most people own a 2lb ball pein hammer. They're not a 'special tool'.

Bearings should either be fitted with a bearing heater (n/a for head
bearings) or a steel hammer. If you use a drift made of something
softer than the bearing you run the risk of leaving bits of it in the
bearing and causing premature failure. You're not going to knock a
lump off of a bearing tapping it in with a 2lb hammer.Obvious really.

 

Fitting head races isn't usually the problem, in my experience. Getting
the old ones out is the bastard.

For races, I drop them in the freezer for a while and then gently tap
them into the headstock, which I've warmed by wrapping it in rags and
pouring boiling water on the rags.

The race that goes on the stem - I put the stem in the freezer and heat
up the bearing.

Do you wait for the doctor to go out and then heat up the bearing in a
pan full of oil? If it helps I can tell you that deep fat fryers are
no good for this.

 

Heh. I just wave a blowlamp at it.

The Doctor has now got very suspicious of any bike bits that find their
way into the house.

This is after I:

(a) Removed the enamel from the bath when the caustic soda leaked out of
the two-stroke silencer I was decoking. In the bath.

b) Filled the kitchen with acrid smoke, heating up a crankcase half in
the over, to free a bearing.

c) Did the same with a fork leg, to get a seal out.

d) Filled the dishwasher with oily emulsion when I put a 400 Four sump
in with the crockery, to clean it (quite recently, that was).

e) *Very* recently, when repairing the Trophy fairing, managed to get
fragments of glass cloth mixed up with the raisins.
