Hi, I'm trying to get the speedo up and running on my 1960 ripple project. It's the one with the speedo that drives the wipers. We've worked out that the speedo was snapping cables. On dismantling it, the box with the gear that drives the wipers that the cable plugs into seems jammed. I can't work out how to dismantle this box to investigate. Anyone have any ideas? Here are some pics...

Hi Cinnamon.

Well, I'm struggling to write this as I'm choked with envy, but hey...

Ok, I know NOTHING about this 'gearbox' of yours, but - just from looking at your second pic - there appears to my eyes to be a 'pin' possibly held in by a circlip (it looks in the photos as tho' there's a ring with a 'gap' in it) in the raised body flange at the top of the pic.

Ie, at the very top of the pic there is a male threaded 'collar'. This collar sits in a raised flange which is part of the case moulding. Going through that raised case moulding - from the front of the photo towards the back - is what looks like a 'pin'; quite a thick pin - possibly a hollow one - but, visualising it, it looks as tho' it will be engaging with this threaded part inside the raised flange. So, my thoughts are that you first need to remove that 'pin'...

Is the pin also visible from the back? If so, if there isn't a circlip holding it in place, or if it doesn't unscrew (does it have any type of screwdriver/hex or whatever way to rotate it?), then I'd guess it is pressed into place. In fact, it might be a split sleeve type thingy - a hollow tube which is split along its length to give it a bit of squashiness so's it can be pressed in with an interference fit.

ALL THE ABOVE IS GUESSWORK!!! Basically, does that 'pin' have a circlip holding it in place? If yes, remove it (D'oh...), if not, try and press it out.

**cough** all at your own risk...

I believe the thing to which DA is referring is what's known as a 'Roll pin',



and you should be able to either drift or press it out, I wouldn't expect it to be very tight.

Like DA I've never actually looked at one of these before so have no idea how it should come apart. Try cleaning the grease out of it to see if that gives a clearer view of whats going on in there.

Cheers, Joolz. Yep, that's the beast I was thinking of
