I'll keep you all posted Bob, though I'm proceeding at a glacial pace.

Received replacement pulley, 180mm PCD.

I'd love to see a photo of the machining of a flywheel for a Taper-Loc bush.
Must be done in quite a large lathe?

i also need a 3kw generator to go with it.

I thought so too, until someone pointed out that I could use a larger output generator (which might be easier to find).
It will produce as much kW as the engine can cope with supplying, then no more.
I hope that's right, because I got an 8 HP alternator.

Here's my portable meter box, apparently made for servicing small gensets according to the leaflet that came with it.
I found it at a swap meet.
It's plugged into a house power outlet, switched on but with no load attached.

Don't panic, folks. There needs to be a white line on the alternator pulley for my digital tacho anyway. :)
I also have a frequency meter, which will look in keeping with the old genset.

I've gotta try it, as all it needs is to paint a line on the pulley.
It would be fun if it works (maybe better under fluoro light?), and could be handy as it's always there.
I shall report!

Lister Based Generators / Alternator Hz tip
« on: June 23, 2019, 11:02:10 AM »
I heard a suggestion for fine-setting of engine speed to obtain the required Hertz.

Assuming pulleys of theoretically near-correct ratio are installed on engine and alternator shafts:
Paint a white line on the alternator pulley, so that with a lamp shining (powered from grid, on a house circuit for example) the line will appear stationery when correct speed is achieved.
It's the same principle that was often seen on hi-fi record player turntables.
Has anyone else heard of this method?

Thanks, I just assumed bearing suppliers would be the highest priced option.
It looks like they are about the same, so I'll check.

For those interested, here's the main bits of the puller I made to remove the stubborn pulley.

These might be a little less expensive:

Price includes Taper-Loc bush, and delivery cost is stated.

I'll likely get one of these, but have feelers out for a used one.
I better go look for a four leaf clover.

Thanks Bob,
I saw that, and would be up for $100 for the pulley, Taper-Loc bush & postage.
I may have to buy it next week, if nothing comes up cheaper.

Looking at my box of miscellaneous pulleys, I must be rich!

I can buy a new pulley at sobering expense.
There's just too many variations to expect to find as a used or surplus part, exactly the one needed for a particular job, unless one is very lucky. ...especially in a small market like Australia. - diameter,, belt section, bore, number of grooves, material.
But I thought I'd give it a shot and ask here.
I have a box of various sized pulleys, and suppose others may do also, perhaps under a bench at the back of the shed. :)
The shaft on the alternator is 1 3/8", or 35mm - so close I think either would be OK.
Looks like Taper-loc (and similiar) are pretty well standard these days. These seem expensive too, even though they must be produced in huge numbers.
I can understand why they are popular. My alternator's old pulley (wrong diameter) was steel, 4 groove and with a long key - and very tight. It did not want to budge, until I brought in heavy weaponry - a custom puller made from inch thick steel plate, with an hydraulic pump and ram, and a blowtorch.
I'd be happy with a plain pulley, even if the shaft hole is too small as I can bore it out.
Come to think, if it's too big, I could bush it smaller.
