Add-on tachometer for diesels

[RVPark]

My used '93 Dodge 250 came with no tachometer - irritating!



I put up with it for a year and finally checked around for a tach add-on for diesels.



I found the "Tiny Tach" made by Design Technology Inc.



This little unit (rectangular and small than a cigarette pack) works from a transducer clamped on the fuel line to any cylinder.



Perhaps a little too sensitive compared the OEM tachs but a great improvement over no tach at all.



$65. 00 plus shipping - easy installation.



I found it at www.tinytach.com under the commercial tachometers.

Thank you! Just ordered one for my older Kubota tractor that came without one, I looked around before but all I found were ones that needed a gear to drive off.

I've always wanted a tach on the tractor so I could use it for spraying. Can't spray unless you can keep the ground speed consistent with a tach.

On the '93 there is wiring under the dash where an ispro tach will plug right in.

When I had the '93, I bought the ispro tach assuming I would have to install a pick up and wiring, but when I opened the box there were instructions on where to find the wire plug -- just tied to the wiring behind the dash'

Good link RVPark

Welcome to TDR forum on your first post.

Anyone that can find a website or product line that Bill (illflem) hasn't found before deserves a big salute!



DTI is the company that produces a very good quality electronic flow (spill port) timing setup. My local diesel shop, Mike's Custom Trucks of Northwood, ND, uses that very setup.

illflem I ordered me one of those Tiny Tachs for a Kubota BX1800 I just bought several weeks ago. It should be in some time this week. Heard about it over on tractorbynet.

I added a tach to my 89 350 by mounting a prox. probe to read the flywheel ring teeth which then could be calibrated to drive an aftermarket tach that I band clamped to the column.



Mine was from Frank L Murphy Co. but you can also find others in a marine supply magazine. It worked great.



Another method to pick up a tach signal is from a signal generator that would mount in the front timing gear cover (they make ones to replace the oil fill tube). This signal generator can then be calibrated to the tach that you choose to use.



Basically, convert a rotating mechanical counting device into a dc signal to drive a tach.

Now I'm wondering if the Tiny Tach injection line pickup inductor can be modified to drive a timing light...

Since this is about tachs, I figured somebody might know something about my(tachs) problem. I just ordered an Isspro 4000 rpm magnet activated tach. I installed everything Sat. and cranked er up on Sunday. Idle=700 rpm; a little low but not serious. WOT = 2000 RPM, about 7-800 rpm off! I checked my magnets, they seem to be 180 deg apart like instructed. The only thing I can figure out is it may be one with a sticky needle like I have heard about on here. Any Ideas?
