Oil pressure guage
 

Hi all,
I would like to replace the hour meter on 782 with oil pressure guage
The engine is a mag 18. Also would like to do it to a CH18 in a CCC782 later
just looking for a suggestion from someone who has already done it or knows
of one that will work

Thanks

i put an oil pressure gauge on my 1811 and it worked out good, i used a black face gauge so it looked factory. i used a mechanical gauge and removed the factory oil pressure sender to hook it up, i could have put a t in and kept the idiot light but i don't need an idiot light if i have a gauge.

So it has a little tube running up to the guage?

Yes, the gauge will come with plastic tubing but I highly recommend buying a copper line kit because there's less chance of a leak and you don't have to worry about it melting. Here's some pics.

Thanks, that guage is way better than that hour meter that I cant read anyway
The IH 782 still has one of those dial ones and its lens is so foggy I cant read it

Thanks again

The M-18 is a drop in replacement for the KT-17. The only modification needed is a small electrical one.

Ditto on the copper line.

I did it, see post #34 and #40 here;

I'm going to throw something out here.:bigthink:
I've been around long before idiot lights on most equipment.
Just how many times do you notice a gauge that is reading in a undesirable range?
Unless we have a concern about a reading and are watching it, we never notice it till it is too late.
This goes for anything we operate.
That Said, Walla!! idiot alert light!!!
Just love the ones that blink and say "check gauges"
It getts your attention quicker than a suggestively clad lady peddling a bicycle in your lane.
Take a minute or two and put in a "T" and screw in a pressure activated sensor as an alert/addition to the gauge.
The only thing better is a telltale stop gauge that shuts off the equipment if temps/pressures are too low or too high.:beerchug:
Now where is my bicycle? :biggrin2:

I may be an exception here, but a suggestively clad lady on a bicycle beats an idiot light anyday. Then again, I am under the age of 90. :biggrin2::beer2:

YUP...... :biggrin2::ROTF1::ExtremeFunny:

In reference to gauges, I have been told by a few people in different motor sports realms (tractor pullers, stock car racers, etc) that they turn the face of an oil pressure gauge so the needle will run straight up (12 o'clock) when the engine is operating at full RPM. Pretty neat idea as all 3 told me they don't have time to stare, just a quick glance, to make sure everything is ok in the heat of the moment.

I would agree.... if this was a race car. Pretty sure on a GT your going to have time to look at the gauge. Heck, you could downright stare at it for 10-15 seconds without missing much. I can't stand a crooked gauge. :biggrin2:

X2 on the light along with the gauge. I have both on my machine.

Stare at it too long and you might become hypnotized into a trance and drive your tractor off a cliff...

But I will be watching what you do, I need a filter and guage (and light?) added to my 782 project.

Copper versus nylon
 

We had a boat way back in '66 that had a copper line to a mechanical oil gauge. The vibration over time broke the copper line and dumped all the oil into the bilge 15 miles offshore. I use nylon line now. Most all oil gauges come with nylon.

Only my 2 cents

But on the Kohler the line has to run past the cylinder on the inside of the tins, I just don't trust the plastic line that much. Also anytime I've ever used the plastic line it never seems to seal as good as the copper.

Just to play devil advocate.....
I installed a gauge on my 1811 about 12 years ago. Used the plastic line. No leaks, and still works. I put about 100hrs a year on it.

I'm not saying it won't work but I'd rather have the copper.

I used copper on mine. You don't have "cracking" problems if you know how to pipe it.

Nylon or plastic tubing and heat........recipe for disaster. But that is my opinion.

:ThumbsUp:

3/16" brake line is inexpensive, easy to work with, don't melt and won't crack if installed improperly/unsupported.
I find it useful.:beerchug:

thats also a good option, we use it on the ford 8n's.

Agree 100%! If SS tubing is good enough for 1 million dollars jet engine it must be good enough for a Cub Cadet :biggrin2:

I know this is an older post. I just got a 782 with a KT-17 II engine (Spec 24302)

I'd like to add an oil pressure gauge.

Are there options for electrical as well as mechanical?

What part do I need to screw into the engine after I remove the threaded plug?

Thanks

yes 12V gauges are avail at auto stores/online, they use a wire instead of tube and work off a sending unit screwed into the pressure port by the dipstick.
Also you can retain your hour meter by relocating it under the hood in a place of your choice.

Oh Boy, here we go. We had a twenty post debate about should copper or nylon line be used on a mechanical gauge. Now we'll have one about what type, size, and covering should the wire be that is used for an electronic gauge.:biggrin2:

I'm having a difficult time finding a simple 2" electronic oil pressure gauge, a 2" DC Voltmeter and a 2" ampmeter gauge....Everything now is LED....When I was a kid and into Hot Rods they were everywhere.

I searched eBay....
oil pressure gauge electric
got 1852 hits.

Guess I wasn't searching the correct term....THANKS!

I added Stewart Warner oil gauges to both of my Cubs- a 1985 1711 and 1986 1811. The install was pretty straightforward. On the 1811, the brass adapter fitting snapped off in the block. I drilled it out and tapped for 1/8"NPT. I added an adapter so that the low pressure switch/idiot light was retained in addition to the new gauge. The Kohler M18 in my 1811 has 1900 plus hours on it. I run Rotella SAE30 oil. After 20 minutes at 80 degrees ambient temp, the oil pressure is almost 60 psi indicated at full throttle while mowing. This should have been standard equipment on all Cubs with a pressurized oiling system.

After you have mowed with yer engine pictured about 5-10 minutes, you might want to check what appears to be nylon line/tubing near the engine fitting where it attaches too.
The heat coming off the cylinder/head is intense there.
If you are comfortable with the searing temperature of it, fine.
if not, you might want to at least make that part of the gauge feed line common 3/16" brake line.
Do be advised the line will be very hot so you don't fry your hand.
Also be advised that the line routing, whatever it is, should not be where it can run on sharp edges/surfaces and wear/chafe a hole which will lead to catastrophic engine failure.
Just a FYI, not to criticize.:beerchug:

On my 784, I installed an Oil Gauge and use Copper Tubing. I was skeptical of the plastic tubing. :beerchug:

I will do that. I have heard horror stories with the copper tube in garden tractor applications cracking due to vibration. I may get some heat shielding for the line. All areas where the line would rub on metal have been shielded with a rubber grommet.

Looks a little wet... is it leaking already?

No leaks after reassembly. All of the oily wetness is from me cranking the engine over with the oil galley exposed to blow out any metal from the area after drilling the broken fitting it out and enlarging it from 1/16" to 1/8".
