Hour Meter

Yooper Farmall · Mar 25, 2013

Rebuilt the engine in my H, thought I"d like to keep track of how many hours I put on it. My wife gifted me with an hour meter. Got to looking at it, white plastic, with its flimsy chrome mounting bracket. In the process of designing a mounting tube to mount it under the fuel tank, behind the belt pulley system. Have two designs so far.

Now hook it up to a switch that works off of engine oil pressure so if you leave the ignition switch on it doesn't keep adding hours. You can also hook the wire to excite a alternator to it

I like that oil pressure switch idea ...
I wonder if there is a second hole in the block I could attach the switch or if I would have to run a T off the hole for the oil pressure gauge.

I have one very similar to yours on a garden tractor. I connected it to the A terminal on the Delco generator as it only gets power when the engine is running. Hal

Yes there is. On the right side of the block at the same height as where the oil pressure gauge line attaches, about half-way towards the front of the engine you will see a small set screw, it is 1/8" pipe thread and has an Allen head. Remove it and screw in your pressure switch.
