Tachometer cable

Re: Tachometer cable

The tach cable can be pulled out of the cable housing from the distributor end but not from the tach end.

Re: Tachometer cable

Jack,

The distributor end of the cable has a permanent collar that prevents it from going any further into the housing while the tach end is plain and yes both ends are square.

Re: Tachometer cable

So, can you remove it from the tach end to lubricate it?

Re: Tachometer cable

Is the inner wire removable? The output gear of the distributer is wiped out, so I suspect a bad cable internally. Can I remove it without disconnecting it from the tach, just to verify. I really don’t want to break my back trying to be a contortionist. Jack J.

Jack,
I suspect if the output gear in the distributor is damaged the tach drive gear on the main shaft is damaged also. This usually comes from the driven gear wearing into the distributor housing and a mis-alignment of the gears causing damage.

I may be wrong here but my memory tells me the inner tach cable removes from the inside of the car.

That's my recollection, too.

Re: Tachometer cable

Since the permanent collar can be installed at either end, it's feasible it would work at either end. Looking at some notes on disassembly, I believe my cable was stored away reversed so the collar should be at the tach end not at the distributor end as mentioned above. I deleted the erroneous pictures that show the collar located at the 'big' fitting because it should be at the small fitting end. Sorry for any confusion.

Re: Tachometer cable

Jack, depending on your dexterity and how tight the nut is on the tach you may be able to reach up and disconnect the cable. I'm able to do that on my 63.

Tach cable at distributor.

Re: Tachometer cable

As Timothy said, the most likely cause of tach gear failure is the having the driven gear wear a depression into the distributor housing, causing misalignment and then destruction of the driven gear and the distributor shaft gear. If this is the case, it has nothing to do with the tach cable, and there is no need to remove it. There is a need to fix the depression worn into the distributor housing however or the new gear and shaft will fail immediately. There may be spacers or washers made to go into the distributor housing to cover the depression. The old way to fix it was to drill and tap a hole at the wear point and install a large set screw to contact the end of the driven gear and hold it in the right place. It worked but was visible from the outside.

Re: Tachometer cable

Jack, I would also look at the bronze shaft bushings on the dist. Housing while your there.
