Hummm,
so how do you remove the collet lock from harmonic balancer and crank??

[jay see]

Are you looking for somewhere to put a puller on? Don't. When I did my timing case seal, I gave it a few desent hits with a soft face hammer and then wiggle it out.

Nar not looking for a puller.
Can clearly see that wouldn't work against a taper lock.
I searched & searched for "collet lock solution" gave up.
I worked out in the end.
Used a bit of pipe with ID a bit larger than the taper lock.
Placed it around the taper, tap tap, and of it all came.
Little shock around the taper did the trick.
Thanks for the input.
cheers

TD42 crank pulley fitting is totally different to TB45.

You did well if you found a tube the right diametre. I used a 25mm brass drift and just went around a few times between the bolts until it loosened.

It's advised to make sure you get the taper lock seated in place with a drift and not try to push it into place with the nut.
You'll clearly hear when it's back as far as it will go.

I was initially advised to just put the nut level with the thread and give the crank end a good whack but I couldn't bring myself to do it..

Got the exh manifold off, it looks to be fairly well port matched going by the exhaust residue and how the gaskets match up to ports.
Only a small amount of port machining to do, to get it humming along better.
time to try the new tools out, last die grinder gave out.

Yes more responsive which will make it feel smoother to drive. If you can aim for 1.5-2kg much more than this will require significant machine time. Also get he clutch and flywheel assembly balanced.

I use a gasket with a smear of loctite 515.

What could I expect to pay for machining 1.5 kg off the flywheel & balance assembly ?.

Not sure but its not a big job and would only take an hour or less for someone to do it on the lathe

So Iv'e made about 30 phone calls and looked @ numerous web pages.
who in the hell machines weight off flywheels and balances them in NSW.
Around the newcastle to sydney radius.
I'm in the middle of that area.

Humm, for us beginners to this mod,
what is mirror balance ?
and neutral balance ?

Have you tried and engine rebuilders? They generally have the tooling for the lighten balance.

It will just be a zero balance mate. Will be difficult to do a mirror balance without opening the engine.

I believe, and correct me if i'm wrong, mirror balance is where they match the harmonic ballancer and the flywheel together on the engine as a rotating assembly and a neutral/zero balance is when they just balance the flywheel on it's own (or including the clutch assembly)
