Sun Tach

[69 Post Sedan]

Can anyone give me an idea of what years these were made?

I have a 8k tach in my car but aquired this recently and thought about installing it.

Thanks, Kurt

That is probably the date August of 1971. http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

nice try Sammy!

I have one in my 67 Nova that I got in 1971,10grander if that helps?

To me it appears that someone had them gone through and inspected 8/91. The marker was too fat and it's hard to make out the "9" but I know they are older than that.

Yes Paul that does help me out...Thanks. http://www.yenko.net/ubbthreads/images/graemlins/beers.gif

Kurt,
I believe the Sun Super Tach (800 series, all electronic-no sender) was introduced in '66. They had a white needle and red shift point arrow. In '69 the face was changed to allow better illunimation of the color band and the needle was made red. (orange). I'm not sure how long that model was offered, but I'd guess through the late '70s until the Super Tach II was introduced.

They also continued to offer the SST-700 model through at least '69 which looked "similar" but required a sender. Any one that has Super on the face is the fully electronic version.

Hope this helps.

I have an SST70 and two SST90s, all three have a green stripe vs. the blue stripe, all three have white needles, and all three require the EB transmitter.
I was always under the impression that the 7K & 9K 270° 'Super Tachs' (green line) required the sender and the 8K & 10K (blue line) were transistorized. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

Dennis,
Going from what I can gather from my old speed equip. catalogs, all the 800 "series" Super tachs were fully transistorized, regardless of max rpm. The one pictured is model 801, which was the 10K tach. The catalog pictures of the 700 series tach (which required the sender) doesn't say SUPER tach on the face. The '69 catalog mentions the newly designed 270' circle and red needle for better viewing (that's on the 800 series). The description doesn't mention a changed face on the 700 series. I have a hunch that the color band doesn't necessarily mean it needs a sender or not. Just going by what the catalog blurb says. I could be wrong. http://www.yenko.net/ubbthreads/images/graemlins/hmmm.gif

Looks at the back, I would say it is about a 72-75 model. The earlier models have a different style back. I would post pictures but I am oiut of town for the holiday. Either way, the face is the 69 up style. An awesome tach that it for 8 cylinder 12 volt applications and does not require a sender.

And what you have (along with its 8,000 RPM brother) was the tach of choice in the late sixties and early seventies. Man there must have been thousands bolted to either the top of the dash or clamped to steering columns. One I had moved from car to car <g>.

Thanks for the responses. I agree...I think it's from the early to mid 70's.

I actually bought two of them with cups and mounting brackets. Although both the brackets are for a dash mount and I wanted a steering wheel mount.

I went through some more catalogs, and found that statement was wrong. The one catalog had the wrong face picture in the 700 series ad. Both the 700 & 800 series had Sun SUPER Tach on the face. Dennis was right - the 700 series were the "odd" limits (7K & 9K) and used a sender. The 800 series were the "even" limits - 6K, 8K & 10K) and they were fully transistorized. (one piece). But the color band change in '69 applied to both the 700 & 800 series. (at least I was right about that). http://www.yenko.net/ubbthreads/images/graemlins/crazy.gif

This is the one I bought & installed in '69 (and it still works!)

I used to have an old catalog that descibed each one, its applications, and if it used a sender or not... of course I currently have no idea where it is... You'd think I'd have this stuff memorized by now, but my mind seems to be reaching its "useless info" limit these days... http://www.yenko.net/ubbthreads/images/graemlins/crazy.gif

OK Joe,
Now it's time for you to take them all out of the boxes and let us know what the date stamps are on the backs.......... http://www.yenko.net/ubbthreads/images/graemlins/scholar.gif I think you have all the answers in that cabinet http://www.yenko.net/ubbthreads/images/graemlins/cool.gif http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

I took the photo below in 1960 - my '53 Corvette with a '57 Buick "nailhead" V-8, 3x2 97's, Harman-Collins roller cam (3x2's replaced by a 6-71 blower with dual WCFB's in 1961); note the "original" Sun tach (with separate transmitter). It was my "Woodward" car, and ran AM/SP (mid-12's) at all the Detroit area strips. Ahhh, the "good old days". http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif

Whoa! Stop right there. That solid axle Vette was a Piece (and it had a Sun tach too!). More pix please!

Best looking Sun Tach ever, very cool John

[SSRSBOB]

There was a guy way back when who marketed these old tachs and gauges in Lititz, PA. Think his name was Dick Lewis. Was at his place many years ago. Does anyone know him? Or if he's still alive and well?

love this stuff...my '57.

Thanks for all the replies! http://www.yenko.net/ubbthreads/images/graemlins/beers.gif

One more question...for now.

The 8k and one of the 10k tachs work perfect. The other 10k tachs is not cooperating.

When the ignition is turned on and the needle buries itself at the 10k mark and stays there even when the motor is running. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

And yes...I double checked that I had the tach wired correctly. http://www.yenko.net/ubbthreads/images/graemlins/grin.gif
