That is how I was told to replace my speedo needle when it popped off just
after it was rebuilt.

Subject: Re: [TR] TR gauge needle position
Hi Dave,
I am wondering how you decided where to point your speedo and/or tach needle
when putting it back on the spindle. When I was restoring my large TR4
gauges I noticed that the needle, when at rest, sits on a piece of 'spring'
wire that protrudes through a hole on the face of dial. Then I noticed a
tiny dot about 1/8" below and behind the O mark. I think that the speedo and
tachs are 'preloaded'! To preload, you remove needle, let spindle find home.
Push needle onto spindle pointing right at that tiny white dot, which is
less than zero. Then depress rest needle wire rest and rotate needle above
rest wire position and release rest wire - now your needle rests on wire -
with slight preloaded!
Makes perfect sense to me, although I have no proof of any of it!
Regards,
Carl '63 TR4 since '74
The only problem is that somehow the tach is running about 500 RPM
below what I think it should be. At idle, the needle just floats off the pin
from "0".
