Anderson Timer Wear?

So how much wear is to much for an Anderson timer? I drive a lot, 3K to 5K a year.

Seems a bit excessive - don't see any lube, though ?

I cleaned up the slimy thing before posting any pictures
This one does not have an oiler flap, so I have never oiled on a regular basis.

No oil. Just that grease that comes in a capsule.

Maybe some Vaseline or distributor cam lube, no oil or grease. That flapper might use a little dressing to smooth it out.

I grease mine with white lithium grease...just a very small schmeer on the flapper. Clean it every 500-600 miles or so and regrease. Have about 4-5K miles on it and is showing some but not a lot of wear, with no perceptible difference in performance.

I decided the wear was too much when I measured the firing time vs. crankshaft position and found the variation unacceptable. Along with that was noticeable contact bounce (i.e. the contacts making and breaking intermittently). While the Andersons I used were great out of the box and extremely reliable with no maintenance, the timing variation as they wore became particularly problematic with running the coils on battery. The first Anderson I had lasted over 10 years, but the next showed up problems a lot sooner - I think they were being made somewhere else by then.

Seems to be typical wear, the flapper should have a dab of hi-strength lube, sold for the Anderson to prolong the life.
This one uses the stiffer spring, made for the Montana 500, and the wear on my '27 was similar, after about 3500 miles. The stiffer spring can cause a bit more wear. Annual cleaning and lube is proper.

Used about 3500 miles on the left, this one had the stiffer Montana 500 spring on the flapper.
And the wear on flapper was off, as should have used a spacer washer (provided with the Anderson kit) to center on contacts, shows off-center wear.

I run an Anderson timer on my 24. When I start to see wear or small grooving on the flapper I use some fine grit sandpaper to make a very smooth surface on it and the contacts. The smoother the better. After later checking it no noticeable wear. I use siliconized grease on mine.

This Anderson shell is original found in this condition, normally buy these and send off for rebuilds. I like the original cases.
Note the how thin the contacts are after running for who knows
how many miles years ago when the T was the car on the roads!
