Don't know what tachometer to buy.

[BusCrazyinFL]

I like to install a tachometer on my Eagle and don't know where to buy one. I have a 8V71 but all I'm finding is for gas engines. Can I use the ones for gas engines and hook it up to the alternator since I don't have a coil?

www.egauges,com sells VDO 3000 rpm tachs,Precision Speed in Phoenix Az can fix you up also

I have an Isspro Tach with hour meter. I called and they set me up with the tach generator running off the back of the blower. Just have to run 2 wires from the engine to the dash. Really like having the tach. Good Luck, TomC

I ran one off my alternator on the Eagle for years.  Make sure you don't get one that goes over 3000 rpm's.

Running a tach from the alternator or a magnetic pickup from the crank are the most economical way to do it,I like the pulse generator myself but it is not cheap

Speedhut makes a complete line of gauges, all custom-made in USA and reasonably priced.   I have two so far, and I'll be getting another soon.   I like that I can spec them to visually match my other gauges.   Well worth a look.

I used the $179 one and it works great.

I found the right tachometer -  a VDO, but I'm curious why it needs to be 3,000 rpm?

Makes it easier to read and calibrate then you know you have problems when it's peg out to 3000 rpm

Because anything.more than 3k is not necessary, and only makes your tach harder to read.

Ok now I understand ok thanks for the info.

I have an Isspro as well, for the last twenty years, wired to a sending unit mounted on the drive at the end of the camshaft (if I recall correctly). There is a threaded cap on the engine that comes off. You need to figure the size of the drive by inserting drill bits into it because there are various sizes. If you want to check that route out, call Steve at International Bus Parts in Apopka, Florida.

My old 1963 Crown Supercoach Schoolie had a mechanical Stewart Warner tack that had a very wide swing reading to 3500 rpm.   Also had an hour meter.

At low cruising speed of 55 mph hauling kids, the tack read 1750 rpm, which was exactly up and down and centered on the dial.  Made reading easy.

But then all the other gauges were set up with normal readings in the 12 o'clock position.  Stewart Warner now makes electronic gauges that look the same?

The tack had a mechanical spinning drive cable that ran all the way from the back of the tack to the amidships old 743 220 Cummings.  Many feet long.  Very mechanical.

Love the sound of the old Cummins NH220. But still like the 6-71 better, 12V-71 even better, 16V-best. Good Luck, TomC

U-tube has good sounds of the forgotten 6-110 Detroit.  Stationary sets and Budd type Doodle Bug self propelled railway passenger cars.  I understand Detroit also made a heavily turbo ed and inter cooled marine version.  Wonder how much power they put out?  Way back in the mechanical Stewart Warner tack day.
