Tachometer dead

[CGarbee]

Guys,
Got a M35A2C that has an inop tachometer. Tacho head and cable are fine (at least, when I disconect from the right angle drive at the front of the engine and spin the cable with my drill, the tachometer works...
So, Asside from just swapping out the right angle drive (anything to worry about on this, tricks to the job?) is there anything I should know as I try to resurect this guage?

Thanks,

That adapter simply spins out of the housing, nothing special there Cabell.

Thanks Kenny,
I didn't think there was from looking at it, but you never know sometimes...

While we're at it, what do you guys use to lube tach and speedo cables? I assume lithium grease?

Norm at Antelope Valley told me the cable is to be left dry, or use a dry lubricant like graphite.
