That's a real pain - at least you have found the issue.

Perhaps owned by a dentist previously  ;D

What is it? / Mysterious Exhaust Teeth
« Last post by Athame57 on Today at 11:32:45 AM »
On four of my eight exhaust collars (CB400F) I have these teeth  ;D in the past I plain put them in the way they came out and thought nothing of it, however in recent months (many) it hasn't been me who put the exhaust system back on so I went to the CMSL site to see if that would help but they didn't exist there. By now I'm taking a closer look at them and they aren't exactly uniform, like my own damn teeth even. It must be some kind of damage or mod by a PO. Can anyone shine any light on this

Its apart again.

Checked crankcases for distortion and found that approx 6 thou out at no.1 main journal housing face of upper case.

There is a lever mark on the inside face of alternator rotor and had not been removed by PO.

It came off fine with threaded bar screwed in to end.

Wondering if PO levered a bit too hard on case.

I am also going to check the mains run out with V blocks and surface plate.

Any experience of crankcase face distortion?

Ted, you have just completed something a younger mechanic would fail at mate.
By the way the chain whilst new was not an expensive one

And let us not forget the elegant and brilliant Scottoiler.  I have one on my bike and it works brilliantly.

Good work Ted.

Its a skill that used to be genuinely labelled "Mechanical Fitter" in which the person assembling etc had to be adaptive with approach to competently build assembled machinery.

What could be "fettled" aspect of structural, mechanical and metallurgy, all part of training to cope with various components from disparate scource being built into one machine.

Quite a valued occupation, when we used to make things in this country  :)

Thanks Dave, have sent them a message.

They will give you a price Steve based on the photos of the parts you send them. However, if you take the parts there yourself without accepting the on-line/emailed quote they can usually do a bit of a deal. That's how I did mine.

The old fashioned method was the big flat tin of grease you heated on  stove,

But several sprays,
I use Silkoline,or Bulldog BDX,

the later is also great as a freeing agents for stuck nuts and bolts,

It freed all my engine studs ,so I could get the motor out,


Applying, take the bike for a run,
Get it warm,

When you get home,

Put on centre stand, in 1st gear so the wheel turns slowly, spray onto chain and sprockets were they meet at the bottom run,

Careful of the over spray
