Well I did a stupid thing. While trying to straighten out the tach needle so it won't get stuck at 4k... I heated it and it shriveled and shrunk like a George Costanza getting out of the pool... significant shrinkage! :eek:

I thought the **** thing was metal... but no... plastic.

So now I'm looking for a substitute... maybe a new gauge or just replacing the needle. Does anyone know how to remove the actual needle? It looks like it's just stuck on there w/ adhesive... but ya never know on an ALFA.

Thanks!
:mad:

I should have a spair tach from an Alfetta GTV. You can have it and just remove the white needle and glue into yours. Let me know if you need it. Or you can buy a used tach in Ebay.

Good luck,

it "should" just be a push on..the one in my 83 i did the same thing and just trimmed the needle a little and re-glued it together and coated it with white nail polish...its hardly noticeable and no longer hits the face at 3.5k.....nice to see im not alone in the "warped needle" department

Thanks Greg... I'm actually in the process of ordering your fuel hoses because I have a strong gas smell especially when cornering. I hope that fixes the problem. I have your vacume hoses and love them!

Alfa Nola,

The best part is George Costanza's significant shrinkage.
LMAO!!

The needle is just pressed on the pin. One fix is to get a small piece of balsa wood and cut/sand it to size, then paint it white. That shouldn't ever warp.

HTH,

Alfetta GT tach and speedo needles work beautifully.Your needle is simply pressed on.Using steady pressure(pull from the center)pull your needle off the shaft.Then simply press the Alfetta needle onto your shaft.It's longer and it won't curl.I have 5 running GTV6s and have replaced the tach and speedo needles on all of them using this technique without problems. Alfetta instrumenta are readily available on Ebay... cheap!

I re-made mine using this stuff called plasti-strut i think, it's available at all good hobby shops and is used for model dioramas and scratchbuilding. I used a bit of U-channel that was the same widthe of the needle, just cut the old one off and glued the new one on but be careful, there is a metal counter weight in the plack part, make sure to glue that back on the right side!!

I'm not exactly sure what you mean here:

Glad to see I'm not the only one who managed to break my needle. Even after warming it up you need to be REALLY careful with 25 year old plastic.

Well, I didn't just break or shrink mine; I used some rocket science, and decided to heat mine over an open flame. It wasn't pretty when it caught on fire....Nor was my commentary!

Hey Guys,

On my GTV6, I purchased a box of standard tooth picks, took the gauge apart. Under a Magnifying glass I lightly sanded the tooth pick down and made it smooth, then cut for length with an exacto knife.

I painted it off white to match the other gauges, and used some epoxy to adhere to the needle body. Worked very well... and quite cheap too. I found that rustoleum off white was a perfect match for my needle.

Cheers
Martin.

Jim, does the shaft remain at a fixed rotation at rest once the needle is removed? In other words, is there anything special you have to do to make sure the new needle is positioned properly when installing it?

Well thaey say a picture paints a thousand words,

Here's a pic of one of the needles (speedo if you really want to know), you can see the "U" shape of the plastic, solid would work just aswell but they only had U in the right width. You can see the two holes (one throught the counter weight and on the other side) which the original needle attaches to. Also in the "hub" (the black plastic thingy) there is a grove which helps to hold the needle in, a bit of cyno (super glue) and roberts your mothers' brother, the job's done.

I did more or less the same thing FrenchGTV did, but I used a C-channel made from brass. You can pick this stuff up at a model or railroading store. I got about 2 feet of the stuff for $2.25 or something like that. I sawed a little piece off to match the old piece in size, sanded it down, filed the tip to be slightly rounded, and then painted it white. Glued on with super glue et voila, c'est parfait. ;) I was initially concerned about the weight of the brass, but it's so thin that it's barely more weight than the old plastic. Seems to work great and will definitely never warp!

I also took the opportunity to spray the round disc in black paint since mine had turned color from sun exposure and was a sort of gray. I figured the opportunity would never present itself again to correct that.
