Jones Tach Ratio.

[dmontzsta]

I have seen a few Jones Tachs for sale, but I am uncertain on which one to get. I want to run it off the V-Drive. Can the ratios be changed?
If my memory is right, V-Drive ratio is 1:1?
Thanks.

If my memory is right, V-Drive ratio is 1:1?
Yep It will go to the top side of the v-drive

Nice find Lou, thanks for that.
It does not look like they carry a 1:1 do you run yours off the distributor?
I wonder if there is a place that can change the ratio of the gauge. I might just have to buy a new unit from Glenwood.
The meetings are slow right now, everyone had to grow their hair out, it is a little cold here. I expect a new group with fresh cuts this summer.

Don, I looked on my reciept and I bought the 2to1 ratio. I think this is correct??? I am not running off of the tach. Somebody else can tell us...RCL
Glad the meetings are going well. I hear Tony is in next year. He looks great bald...

Yeah, hopefully some tach experts can chime in.
I am pretty sure 2:1 is for the distributor. 1:1 is off the V-Drive.
lol. I cant imagine Tony bald...

Every tach drive I've seen on a v-drive was 2to1, but you can always pop the cap and check it just to make sure!..

how do you tell what you have. when i took my cole out the tach only read appox. 4250 r.p.m.'s :idea:

[GofastRacer]

Pop the drive off the v-drive, turn the v-drive end two turns, the tach end should turn once!.

Art, you da man. I was hoping I was right. I didnt want to have to send the tach back.
