Split pin size

Nos4r2 · 11 June 2013, 16:24

Does anyone know the split pin size that's used on Hallmark RollerCoaster trailer rollers?

I need to get a set of stainless ones, and it'd be easier to order them online without having to jack the boat up to remove one and measure it.

I have a question about this... I've had a few split pins corroding through of late, and then the roller on the dumbell falls down and my hull gets scraped!

If using a stainless split pin through the Galvanised dumbell, will the two metals interact? Is that why they are mild steel in the first place?

Continuing the hijack, sorry;

Probably mild steel because it's cheaper and more readily available. I'd put stainless in and inspect a little more often. Shouldn't react though (and a bit of anti-seize would reduce the reactivity in any case.)

Agreed (though I didn't use anti-seize). I changed all the split pins, washers, nuts and bolts on my trailer some moons ago. No sign of corrosion, which is more than could be said of the mild steel crap that came off

Two items that are seemingly no-brainers, but worth a little research when buying: Cotter pins (or split pins for you UK/Euro guys), and hose clamps. They're both widely available in a standard, non-marine version, which will quickly fail with salt exposure. A bit of hunting will get you stainless versions, which will last substantially longer. Worth the added effort and cost, IMO.
