Robin Engine Blows Main Seal

Piedmont3 · Jun 8, 2005

I talked to the Mechanic Yesterday evening. /forums/images/graemlins/mad.gif
He said, I can come get mt PT today. /forums/images/graemlins/blush.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/laugh.gif
He started taking the engine apart to see what the problem was and found that it was only an oil cooler line. NOT the main seal. It is covered under the Robin engine warranty. NO cost to me, except transportation and time.
By the way.
The mechanic is very helpful, and I would highly recommend him to anyone that is close to the OKC area.

I have down loaded the Kohler engine manual. According to the Kohler manual when the engine is applied to a vehicle the oil sentry is to be connected to a warning light. On my PT 425 the oil sentry is not connected it is the green wire coming out of the wiring harness near the valve cover on the right side of the engine. If you would connect it as you are posting and you used the machine on a steep hill I'm afraid you would be taking a nice unscheduled ride.. If you would like it to function just install a warning light on the control panel. The contacts close when the oil pressure goes below 3-5 psi according to the manual.

I am glad you've got everything taken care of, I am sorry I didn't see this post earlier as I have pretty much no time lately to visit this forum. Busy busy busy here for us at RAI during the summer time.

(KOHLER uses an 'Oil Sentry' which shuts down the engine if oil pressure drops below a certain level!!) 

Wouldn't that be luverly? <Sung to well known melody>

(I'm resurrecting this thread/post because someone linked to it from the one covering ElBubba's current blow-out, and I missed it originally)

After looking at the Kohler wiring diagrams and service literature (what I could find of it), and tracing the wiring on my own PT-425, I have concluded that the 'Oil Sentry' equipped Kohlers come with the means for the OEM equipment maker to provide either a warning light or buzzer, or an automatic engine shutdown function. Power Trac seems to have chosen to do neither.

In other words, it isn't hooked up and doesn't function on a PT-425 -- at least not on mine. /forums/images/graemlins/shocked.gif /forums/images/graemlins/confused.gif /forums/images/graemlins/frown.gif /forums/images/graemlins/mad.gif

I hooked my pressure switch on a 422 to a light and sonalert tone generator. Works great.

Can you hear it when you are mowing and wearing ear protection?

BobRip · Aug 4, 2005

I don't know, it has never come on when the engine is running. I suspect it would be hard to hear with the engine running. It does have a pulsing tone which is much easier to hear. My main purpose for the sonalert is to remind me if I leave the key on. This has happened twice and I have added about 20 hours to the hour meter.
The oil light is located where the light switch used to be and I put light switches (qty 4) under the canopy. I can individually control each front light, the backup light and a flashing amber light.

Yep, I am familiar with the feeling you get when you discover what you have done. /forums/images/graemlins/crazy.gif /forums/images/graemlins/frown.gif
