we have a 23 hp 3 cyl diesel motor from shibaura , it came out of a bus air conditioning unit . We understand it to be a standard small tractor notor . At the moment I am trying to fit a rev counter to it , as we have fitted the motor to a log splitter , and need the revs to calculate the hydraulic pump type and size . Where do fit/mount a rev counter to this motor , there do not appear to be any pick ups for the munting or connection . Many thanks in advance from a newbie

That might be difficult in your case, as typically the rev counter would be installed on the tractor bellhousing - counting revolutions of the flywheel.

I use a hand-held tachometer made by Stewart-Warner Model No. 82682. It cost about $70US. It's great for checking anything with a shaft that rotates---motors, engines, pumps. A rubber tip transmits power to the drive mechanism when lightly held against the center of the shaft. ....

Empirekitchen,

See Ebay Item #120202642501

There are many other makes and models available. Search ebay for PHOTO TACHOMETER, or LASER TACHOMETER.

Be sure to get yourself some reflective strips, if necessary.

Diesels don't have as much range as gas engines, which typically work from around 1000-1500 to 5-6000. The ear is a pretty good estimator for a narrow range, and you can assume your small tractor motor will idle at around 500 and top at the low 2000's. So you can safely tell the hydraulics guys 2000. ....
