Smiths PN 80mph speedo - anyone fiddled?
#1
The PN is the same 2240 turns as the PA but has the canted exit at the back of the instrument.
The insides are subtly different and there appear to be less balls to get lost than with the PA. (I've read all the helpful PA instructions from various parties on the web).
I've got a PN in bits and would like to know if anyone has disassembled one so I can see if there is anything missing. I think it all has the prospect of working, but the sitting of the conical end into the bush next to where the speedo cable screws... that is where I'm wondering if all is correct. Pics... anyone remember fixing one? The brass thing seems odd as the whole of the bit on the right is going to be spinning. I can see it has a stop for the gimball-like things, but surely its going to snag on the inside of the case casting?
