Vespa 152L2 1959 - crankshaft puller, help please

[chrisbwy]

Hi All,

In relation to my other recent thread entitled "Vespa 152L2 1959 - bent/misaligned crankshaft assembly?", can you please give me some advice on a suitable crankshaft puller tool?

I was going to use a few thick washers and the clutch basket nut to pull the crankshaft through the bearing. But the thread form on the end of the crankshaft, clutch side, is a bit worn and I'd prefer to use it as little as possible. So I was hoping for once to connect the puller and a second time for the the clutch nut.

So with this in mind can you recommend a suitable puller?

I had thought about a simple coupling nut and then a suitable length of threaded bar but what's the crankshaft thread on the clutch side? Is it M12 x 1.5 or M12 x 1.75 ? Do suitable coupling nuts exist? Or is there an enomonical puller designed specifically for this job?

Your help and advice, as always. much appreciated.

I have posted this elsewhere - so apologies if you're reading it twice. I'm in the UK.

Thanks

Chris

Not having one, I would have thought the thread would be UNF, not metric, especially with it being built in 1959. Whitworth and UNC were still being used too, but would be surprised if it was any of these. Probably half inch or 9/16ths?
