Low oil in engine shutdown

I am putting a Cat-Shibaura engine in a skidsteer. Would like to hook some kind of low oil level alert system. See there are several mfg's available. Does anyone have one that they like? Do not want low oil pressure cutout.
 
When you say you don't want a 'cutout', I assume you mean you don't want it to shut the engine down. Regardless, it's not difficult to wire up one without spending a lot of money on a system made by Murphy or some other mfg., and even easier if you don't want to incorporate a shutdown function.

Basically all you need is a switch that is NC at whatever pressure you want the alarm to come on at, and open above that. I usually use one that closes around 5 to 10 psi.

Put the switch in line where it senses the engine oil pressure. You'll feed power to the pressure switch with a positive wire attached to a circuit that has power on when the ignition is on. The feed from the pressure switch will then go to the alarm, light, or both that you decide to use to indicate the low oil pressure condition. When the engine oil pressure rises, the contacts open, and it will break the circuit so the alarm will stop. If oil pressure drops below the switch setting, the contacts will close and the alarm will sound.

Without a lot of extra wiring the alarm will indicate low oil pressure until the engine builds pressure, which should be before it starts.

If you decide you want a shutdown function, post back and I can explain the wiring on that setup also.

I tried to find a switch available through NAPA, but their site is nearly impossible without a model number for a vehicle. If they get in the Ecklin book they should have no problem finding you what you need. If they can't, post back and I can look in my book and find you a part number.

You can also wire a temp switch in on the coolant to alarm for high engine temp, if needed, without a lot of extra effort.

Here is a link to NASON's site. They make just about any switch you might want if you want a little higher quality switch.

Ken and Leroy,

I assume you have never had a 1/2 inch oil cooler line crack while operating your machine, thats not easily seen from the operators platform? As the engine oil pump empties your crankcase contents on the ground.
