Name that tool

I think if and when you find one you will pay an arm and leg for it and only use it for the one occasion.

I would make one out of a sheet of 6mm x 300mm x 500mm ply (or similar) and

2 x M10 bolts/nuts. Cut a V in one end of the ply to clear the fly wheel boss (looks like about 50mm will do), drill 2 x 11mm holes at the pitch of the fin/viewing holes (if they are same) insert M10 bolts, apply nuts and hey presto a quick fix...........and you don't have to face the hairies.

then sell it on ebay.............

I should have thought the tool to use is a strap wrench or a chain wrench although the latter may damage the aluminium casting. Most good tool shops will sell you a strap wrench and it should not be that expensive. Make a note of the circumference of the casting as you don't want one that is too short.

Strap wrenches are normally used for removing the oil filter from engine.

YEp, a couple of bits of any old steel will do.

Either of them can damage that. It'll judder like a bastard if you disto= rt =

it.

I can't see why a strap wrench would cause distortion as it applies pressure equally all the way round.

If the OP is so concerned about embarrassment, why does he not call the service department of the main dealer for the scooter and ask? Perhaps the manufacturers supply a special tool for this job, but I rather suspect it won't be cheap.

Thanks for the replies guys.

I'm aware of the function and operation of the tool, I made one up years ago to tighten the crankshaft pulley back on my Renault 5. I was checking the valve clearances so I had a spanner on the pulley bolt to turn the engine with only I forgot to take it off when I finished :)

I was just wondering if it had a specific name to make the process of blagging one for an afternoon easier.

He's not so concerned about embarrassment, he was just trying to be funny.

I suspect you are probably correct .

It's the sort of special tool which is fine if you're doing this job every day but likely far too expensive for a single use, and often has to be ordered.

If you have a dealer near you it might be worth trying to hire one over say a weekend by offering a large cash deposit.

Making something might not be difficult, but how strong it needs to be depends on how tight the nut is.

Try one on an empty can, they apply a significant crussing force at the point where you apply the leverage. If they just applied equal pressure then they wouldn't turn anythibg.

I've always heard such things referred to as "where's that bloody tool for undoing the whatever"

In the end he bought an electric impact wrench for the job, he said it all came apart very easily (and presumably back together :)
