Motor Triple and Spirol Pins

[richflat]

Hello, I’m in the process of rescuing a Ransomes Motor Triple. After using the world’s supply of penetrating oil to deal with years of rust to get various items freed and working again I’ve been stumped by some Spirol pins. When I’ve taken the hockey stick arms off the pins were extremely rusted and I’m looking to replace them. Does anyone know the correct dimensions for these pins as I only have corroded fragments left to guess with?

Hi. I can’t answer as to what size the holes are but selection sets of these pins (spiral or roll pins) with various diameters and lengths are available on ebay, Amazon and engineering suppliers.

If you have a good selection of drill bits you could see which is the closest fit to measure the hole diameter.

I hope this helps.

Many thanks, I was debating that this might be an option. Thanks for the input.

Also the Ransomes website has all the operators manuals and spare parts catalogs available to down load including all their out of production models for free.
The parts catalogs includes part numbers for the spirol pins so it might be worth contacting them to see if they can tell you the required pin size.
