The new Sapphire 460ss! Key features of the new 460: The heart of this high-performance truckmount is the 38 HP Kohler engine, backed by a 3-year Kohler warranty. Tube and shell oil cooler reduces engine oil temperature by 20%, increasing engine life and pre-heating incoming water. Innovative frame and muffler design improves serviceability. Patent-pending air ...

WOW! Another TM .....

I'm having one of the first ones installed into a new van this week.

 

[hogjowl]

What made you choose that particular TM over all the others that are available to us?

 

[mwall2230]

I bought the 870 this year and have really liked it. I liked the specs on the new 460, 38 hp Kohler, 408 blower and 1500psi heated.

You hiring? I wanna play.

Is there going to be one set up at Mikefest..........

 

[hogjowl]

I like the idea of heated 1500 psi.

 

[Chris A]

so its a 454 with a kohler? what else am I missing?

 

[SamIam]

I think the 454 had a briggs in it. they must have not liked the briggs engine

I had some servicing done on my 25HP Kohler in Sept. Used a laser thermometer on the oil filter, read 200F. I got the idea of using a HX on the oil to cool it and preheat water. Someone asked if the 25 has a strong enough oil pump to push the extra oil. Anyone know?
Makes sense, won't over heat the water like blower/exhaust HX will, no need for a diverter.

In my opinion oil needs to be hot where its thin enough to do it's job and lubricate. Don't you think putting the oil cooler into an HX type application would cool the oil too much and lose the effectiveness in lubricating the cylinder walls?

 

[Ron Werner]

needs to be thin enough, but also thick enough. What's the operating temp thats optimum for oil?
I would imagine too hot and it breaks down faster. Too cool, and its like you said, it isn't getting where it needs to get.

Steam Way used a simple oil cooler to preheat water. I viewed it as a marketing gimmick. Doubt it hurt anything though.

I know the motor oil needs to be kept at a certain temperature and not over heated. And I'm pretty sure that's why engine manufacturers put the oil cooler on them. And they usually put just the right size cooler to perform. If we are going to further cool down that oil, to gain a bit of lukewarm water, it will most certainly be running too cold for optimum engine performance.

It needs to be warm enough to flow and to evaporate moisture and unburned fuel. They do make thermostats that divert some of the oil away from the cooler to maintain a constant oil temp:
