Sleeve nuts for 4CA ignition plate - replacements ?
« on: 14 June, 2018, 11:31:02 »
mine are mashed and I need replacements to check/replace points & condenser. Will be a pliers job getting them off then they'll be dead.

Spent a few hours searching on line last night with no joy.

If anyone knows a supplier I'd be happy to hear.

Ordinary hexagon nuts instead?

looks a very close fit. Not sure could get to & adjust. Also not sure what the thread is. But if you know otherwise.

Yes, just had a look at mine.  A few months ago I thought I'd try ordinary nuts, but haven't got round to it, and, as you say, it might be difficult to get access with a spanner. From memory, I think they're 4BA, but I'm not certain.

My sleeve nuts are round section with a slot for tightening/loosening, which seems to me an odd design. I have several washers underneath in order that the slot is proud of the top of the screw so that I can get a screwdriver on. The slot seems to me not a very robust design, easily chewed up.

Phil.

Yes mine similar. Except they're mashed and not proud anymore despite washers.

I can only presume they used this design as spanners/sockets can't get there.
