Tachometer cable BMC 1.5

[BMC90]

Hi.

I need a new tachometer cable for my BMC 1.5 Diesel, do any of you know where to buy this? It´s a long cable, about 3 meters.

Have you tried Calcutt?

If Calcutt can't help I suspect you will have to look in vintage machinery magazines and with a bit of luck you will find someone who can make new inners up fr you. They may need your ends of the outer to fit on a new length if that is what is needed.

 

Personally, If I were going to keep the boat I would mod the alternator (if needed) to get a phase tap and fit an electric one. Probably less trouble.

Are the cables anything like those used for motorbike speedometers? If so that could be another source.

I think the screw on end fitting at the engine end is rather larger than a "car" speedo cable and the outer was very different. All from about 1 50 year old memory so cant be 100% certain.

I think these are like the cables that were used on BMC sports cars, Healeys MGA etc.  They ran off the rear of the dynamo. Try the specialist car restorers?

How about this one?

I think I have seen some driven from the camshaft on the back let hand side if the engine. If it si dynamo driven then it should be much easier to get a replacement.

you are right, an electric would last for ever i think, i just dont know how do it, and what the costs would be.

Might not be long enough. I believe that the Nuffield tractors had BMC 1.5 engines so there is a good chance that the fittings are the same.

Alternator off and to a specialist to have a phase tap soldered on if there is no W terminal, probably about £20

 

Tacho from about £45 (ebay) to around £100 but make sure it is NOT for connecting to an ignition coil.
