CUCV M1028 Tach Assistance

[cavetech]

I have a M1028 that I am delighted with. I would like to install a tach to keep an eye on engine RPM's.

How can this be done with the 6.2 engine? I heard one can be plugged in to the back of the alternator. What tach should I buy?



I thought I would show it off.

Thanks,

Steve

Look into a tach called "Tiny tach" easy to install.

It's been discussed at length. There are a number of options available. There are some tachs that can sense the RPM from the alternator, others require an optical sensor.


A quick search on "tachometer" shows hundreds of threads. You've got some reading to do!



That is one clean machine you've got there! I like it!


Too bad someone vandalized it with that white paint, though.

Aside from the tiny tach and the autometer gauge that has a sending unit which wraps around the alternator, there is very little content on the internet regarding a proper tach install on a 6.2 engine. Good luck on your search and post up if you are able to make something work.

I had posted all this information in the past about the 2" tach. I have a VDO tack that is triggered by the left alternator pickup point. Been using it for 5 years with out fail. I have posted better pictures but this is what I pulled out of my hat at this time. I will locate the box the VDO tach came in and give you better information. Sorry for the crappy pictures of my zero budget build.

I went and got the VDO package that my tach came in. It is a VDO 333-965.

There is more to it then this but as recall it was not all that difficult to calibrate. I paid an alternator shop to do the calibration and hook up.

Can't go wrong with the TinyTach. Be sure to paint the transducer after install. Great unit and super easy install. Really nice looking truck also.

I don't really need a tach but when the 4 speed goes in the wrecker project, I'll ditch the vaacum pump and install a tach drive in it's place.

Another vote for tiny tach. Very easy install and works great.

There is a company called Speed Hut:
http://www.speedhut.com/gauges/diesel-tach/search:diesel+tach
That link will take you to their diesel tach section. I don't have their tach yet but have several of their other gauges and I love them!
If you check them out, make sure you look at all of the customization options for their gauges, not just the display pics. You can change face color, font, back light color,on and on, many different things. Their web page isn't the easiest to navigate, but you can give them a call, they are really nice to deal with. They have diesel tachs ranging from 21/16" to 4", different trigger style too. You can look under dual gauges also, or in some cases they can make a one off for you if you have special needs.
Great quality and they are made here in America! They aren't the cheapest but I don't think you can beat the quality!
You have a really nice, clean looking truck!! I hope you enjoy!!

If you check my thread on M1008 recovery and modification you will see details on how I installed a tach on my truck. I even put the micro switch setting for it.

I am not a big fan of the Tiny Tach. To begin with, part of the romance of driving these 30-year old trucks is the feeling of operating a machine from the 1980's, before the time of computers, email, iPhones, credit cards, health insurance, O.J. Simpson, terrorists, Obama, Justin Bieber and Miley Cyrus. When I climb up into my M1028, I go back in time. Suddenly I am the master of my analog machine, with no computers or text messages interupting my thought process or requiring me to respond. I am free to drive where-ever I choose without any interference from modern technology. My finger is on the pulse of my truck; I am listening to the engine and drive-train noise; I am watching the idiot lights, hoping the oil pressure and water temperature sending units continue to work but have no reason to send an alarm; I am in another world. Somehow, the digital read-out of the Tiny Tach just doesn't fit within this picture. I apologize to all those fellow SS members who have installed the Tiny Tach, however there is no way I could install such a device in my truck.

I hope this inspires thought and self-evaluation.

The tech I put in my truck is analog and has been working great. I tapped into the brown line coming from the alternator.

Same as the VDO. Great set up and has been on my truck 5 years with out fail.

Or maybe even the 1960's!

Here’s an ad for Sun tachs from 1966:

Or maybe..... 1817? Hmmm. Not many cellphones around then.

The first mechanical tachometers were based on measuring the centrifugal force, similar to the operation of a centrifugal governor. The inventor is assumed to be the German engineer Dietrich Uhlhorn; he used it for measuring the speed of machines in 1817.

I hope this inspires thought and self-evaluation.

Oh, bless me father, for I have sinned! I have departed from The Sacred OEM! I must reflect and repent!






Hey, drive by ear and idiot lights if you want to. It's your truck, knock yourself out.


But get over yourself!

goldneagle,

What is the model number / part number for the Deutz you installed?

Thank You

Joseph
