Building a "Factory" Tachometer for the FJ40 (3 Viewers)

[watrob]

Rob that is Keith's one - he says again.

I have need for one more if you can lay you hands on one, did send you a PM

Ok, I think there one up at the beach house, I am uo there this weekend.

Glad that my Biltong (your snack) helped during this fine job.

Welldone JT. Mine is in the post!

 

[DomSmith]

Excellent Tech. Love to see people tackling these things.

 

[hudyhue]

nice work bro..real clean....i'll take one

 

[Friendly Persuasion]

Do the BJ's in Canada have these factory tachs as well?

 

[pbgbottle]

don't think so

i was looking at the parts catalog and it lists a tach for the FJ40 also .would it still work off a magnet on
the flywheel as well?? or might it be something like what you are building ?

10/81-10/84 BJ42,HJ47 #83270-60010 AUS
10/81-10/84 FJ40,FJ45 #83270-60030 AUS

Should work the same (-) signal off the coil, but what are the chances of finding one, mine is a Feb '84 Aus spec FJ and was not fitted with one so where are they

 

[pbgbottle]

who knows . would be interesting to find one.

got to Spector off road and do search by part number and type this number in 172-81, it says they have used FJ40 tachs for $70 and BJ diesel models used for $90, I never seen this before on their website until now, ?

Good luck

Spectre is on your jock.Yours looks great.I'm impressed...so are those California Condors...might as well be vultures.

 

[KY Longhunter]

Did anyone ever verify if a stock FJ40 Tach from SOR would work ?

Yes or no, Im not mechanicaly inclined...

 

[CruiserStuff]

Man, that thing looks SUUUUEEEET! I want one....where do I sign?

 

[2manycruisers]

so after you dremel out the pins to rotate the circuit board, how do you re-connect the circuit board to the backing plate? I want to do this for my fj45, but don't want to screw it up.

cheers,

 

[Teebag]

Look closely at the areas indicated with the yellow arrows, you will see that I cut grooves in both the case and the centre portion, the circuit board is held in place in these groves and fixed with a few blobs of clear silicone.

Hope that helps.

 

[2manycruisers]

That's what I needed, thanks!!
Now to find time....

question:

What if you took the faceplate from the BJ45s gauge and exchanged it for the FJ60s faceplate?

Would that work - they seem to be calibrated the same.

 

[Teebag]

It can work, have done it where the BJ40 faceplate had too much rust, but the flat section of the FJ60 face may let a little too much light at the bottom. Waiting for owner to fit to see.

 

[Cruiser1975]

Very nice!

My previous owner already cut and installed a replacement tachometer, but I'm not pleased with it.

1: cheesy looking and goes up to 8000 rpm unnecessarily.
2: Sticks WAY back behind the dash, interfering with the ducting for my driver's side defrost.

Ideally I'd like to replace the existing tach in the same location (no more cutting my dash!) with a more authentic looking tach (matching number font and size and background color/lines/lighting) that doesn't sit SO far back behind the dash, and goes up to 4000 rpm. 6000 rpm at worst.

JC Whitney (and others) have a Jeep replacement tachometer (see attached) that has a smilar font, and runs up to 6000rpm. I sorta like it. But I'm not sure about dimensions and how it will look lighted.

Ideas?

That tach is awesome, looks factory, I've never seen that before.
