Flywheel and key 2" burrell

Advice needed on fitting the flywheel key mine go's in the keyway for about 4mm do you just it hit with hammer the
Rest of the way I'm bothered in case I bend the key
Any advice would be appreciated
Thanks steve

You'll need to file the key so that it goes in further. I filed mine so that it fitted to about 10mm short of the flywheel. Then tapped it so it sits around 5mm short of flywheel. Another smallmmod that I did, was to drill 2 small indents into the shaft where the grubscrews sit. This gives a more secure fitting on the shaft in my view. Ìt aĺso meant that I could keep taking off a replacing the flywheel without the key being forced in, while needing to turn the crank for setting eccentrics etc.

Hi Steve,

Mike

Hi Mike yes been a long journey I'm been waiting for the governor that's all I need

I've had it running on air and all well been and got steam coal this morning

Steve

That sounds brilliant! Did you have any problems when running on air? I must admit, that I'm totally in the dark with steam, I'm lucky that I have connected up with avfather and son who own a full size and a couple of 3 inch engines who are going to pop around and help and advise. Are you going to the Doncaster steam and modellers show on 12th -14th May
Mike

Hi Mike didn't have any problems running on air only that my compressor could not keep up with the demand
What day are you at Doncaster
Steve

Do you have a large compressor? We are getting to the Premier inn on Friday 12th, going to the show on the Saturday, coming back home on the Sunday 14th.
Mike

Its a 24 litre tank would be better with a 50 litre it would keep it going for longer
Steve

Ah, right. I'll get the two guys I mentioned earlier to test mine. They know what they sre doing. I hope.
