Machine mart battery lead/windshield wiper puller, about a tenner. They are great for pulling the leads off conical car battery terminals, the wiper blades off the spline on the drive shaft, prop drivers of model engines and also pulling props off when you haven't made enough clearance in the hole for the nose of the crankshaft.

A note of caution, they WON'T pull the corks out of prosecco bottles devil.

Warm this with an heat gun, or your method, as this will help it off

Aluminium expands more quickly than the steel shaft that it conceals

The battery terminal pullers don't have enough room for crankshafts on most engines as the legs are not long enough; especially ASP or SC that have a very long threaded section .There are some pullers on eBay that are perfect for prop driver cost about £6 ish.

I borrowed a small Bergen puller to take off the prop driver on my Moki 61LS it had an abnormally tight fit and has a large cone on it. It took a lot of pressure but came off easy with the Bergen arbour bearing puller he removed his saito FA40 prop driver with it also it did not really mark it up either and the puller jaws are quite fine but very strong worth a look at least they make a few sizes I used the small I think. I will be buying one for myself in the future. Quicker and easier than heating the alloy up wrap a piece of leather and it probably won't mark it at all.

Raid the wife's washing basket and take two beechwood clothes pegs.Discard springs and use the four remaining wedges to insert between crankcase and prop driver.Lightly tap in tight with small hammer,then just keep tapping until driver is gently levered off.It will not gall the metal like a metal tool most certainly will. Heating will only help with an all aluminium driver,many have a brass bushing so heat not so effective.Emphasise,just tap the wood,not any metal.

Please check out these pix, then decide if you can trust this poster's advice.saito 82 and sc61.jpg

This last pic shows the noses of an sc 61 on the left and a saito 82 on the right.

The other two pix show the puller in position ready to pull the prop drivers off. Couple of caveats, always, but always leave the prop nut on screwed out of the way of the puller, apply heavy pressure and then tap the end of the screw with a small hammer which will cause the driver to fly off, hence why you should leave the nut in place.

I have pulled the drivers off both the above engines plus a saito 125, ys 110 fz, ys 45 2 stroke, sc 15, irvine 72 and one each of a laser 70 and 80 with no problem.

I think that's a little strong - ED has a long history of posting on engine related matters and has a wealth of knowledge that I would hesitate to question. Perhaps all terminal pullers are not equal?

This poster does try to offer helpful advice and many terminal pullers DONT have the capacity to accept the crankshaft. Your puller obviously does but even that is at its limit from the pics you posted. Perhaps you should give details ,make etc of your puller .

As I read it, ED was merely pointing out that the battery puller has its limitations - he wasn't impugning your character and I think you've taken offence where none was intended, Braddock.

There are always alternatives offered in threads asking for advice. Clearly, your suggestion works for you. The OP will make up his own mind, I'm sure.

Meanwhile, let's all be nice to each other, eh?smile

Thanks for that useful link - I've been looking for something similar for a while!

ED - if you have some alternatives, perhaps you'd like to 'put up'...

That looks the business!

My weapon of choice is adapted from a bearing puller - cost £0 as I already had it for other duties but it will shift the most stubborn taper with consumate ease!

Braddock VC - it might pay to use the crankshaft nut to protect the end of the crankshaft thread - the nut will still prevent any parts being distributed around the workshop or into parts of your anatomy!

The first one is very much like the Bergen one I mentioned I don't know the quality of the £4.34 one but it looks the same the second one looks bad at the jaws. The my dad payed £14 for both the small and the larger version so that price is about right.

Never needed a hub puller on any FS engine I've dismantled. Small blowtorch on the drive hub always released it. And yes you can trust my advice

I never needed one either stripped a lot of engines in the past using a blow torch aswell but then I got a second hand Saito 1.80 and a moki 61LS and there was no way it was coming off even with a lot of heat and a hammer. After using a puller I have to say it is a lot quicker and easier to get the engine apart and on my West engines I don't want to ruin the anodizing great tool and at the price it costs a good investment will last a lifetime.

They look useful - thanks. I'd probably go for the slightly more expensive, but more refined versions also listed.

I'm not averse to using heat, but unless you're replacing bearings, proceed with caution or you may damage the seals.
