Roller Coaster split pin size?

I need to change out the split pins on my rollers. They are very rusty.
If i take one out to measure it, I don't think it will survive and i will left with a lose roller until I can get the replacements.

I phoned Indespension and they couldn't tell me or have any in stock.

Does anyone know?

It's a Roller Coaster 5, if it makes any difference.

Thanks

Worth checking first that you can actually remove them. I started the same job and had to drill out the split pins on the first set as the steel had corroded itself solid with the aluminium. After that I decided it was going to take so much time to do I stayed with the rusty split pins. Will have to tackle it one day though.

When you change the spilt pins out, put some Duralac in the aluminium arm holes, this should prevent the galvanic corrosion between the aluminium roller arms and steel split pins.

I've bought stainless stock from my own measurements and will try one tonight - will report back. Mine is a Super Rollercoaster and longer - assuming same pin sizes?

Did you try using a pin punch to knock them out? I don't fancy drilling them out, there's 48 to do!

Great thanks Willk. Looking on the website, there are 2 different sizes of roller but they have the same bore size, so the pins should be the same.

Good match at 5mm A2 stainless from this guy:

https://www.ebay.co.uk/itm/5mm-3-16-...TAfVzrvgSxnHfw

I bought 40mm to play safe but I'll have to nip a few mm off them. 36mm deffo OK - 32mm might be pushing yer luck!

Tried a punch but absolutely no joy. Then again the trailer is 15 years old. Had 98 to do so decided giving up after 2 was easier.
