U don't need one

A trans cooler is to cool a transmission

If u wish to fit an oil cooler then u would have to run a hose to a pump to the cooler then back to the sump

These small industrial motors don't have inbuilt oil pumps like cars

Why do u wish to do this
Has the engine already got some extreme mods

These motors really don't need this in stock of almost stock form

The difference between a transmission cooler and an oil cooler is... Nothing! A transmission cooler IS an oil cooler, and only really becomes a transmission cooler when its purpose is to cool a transmission...

That said- It could be done, but why? Because it's "neat"? Sure, why not. You would indeed need a small tranny cooler/radiator/oil cooler/whatever-you-want-to-call-it, some appropriate tubing and fittings, and a pump that is up to the task and reliable.

You'd have to drill and tap a couple holes in the crankcase. I would suggest a filter unit too- it's one thing for a splash-lube engine to rely on particles falling to the bottom and staying there, but when you're pumping the oil around, you risk further circulating any debris.

Let's assume that the engine is properly tuned, running right, all cooling system components functioning properly. Under those circumstances, I'd suspect it'd lower the temp a few degrees, but probably not by a lot.

To get greater cooling efficiency, a fan to draw the air through the radiator is a good idea, and so would be a shroud.

Let's also keep in mind that these engines were designed to keep themselves at a reasonable operating temperature all day long. An auxiliary cooler shouldn't be necessary. If the engine is overheating, it's best to address the issue directly.

And another point- it IS possible to to run an engine TOO cool!

It's true that almost all air cooled coolers are the same
Radiators, condensers, trans, hydraulic, oil

Just a mis use of terms
Or a mis understanding of the internals of an engine

An oil cooler from a motorcycle would best suit what u want
One from a car would be too big

U may need a few more components
U will need some way to control temperature ie a thermo switch and fan
Also a filter is a good idea

Sorry fowler- that wasn't so much to correct you, as it was an attempt to clarify the concepts to someone not familiar with them.

Unless your motor is in a confined space and only able to re-circulate hot air, (like inside a box),fresh air intake for carb and exhaust run outside the box, THEN yes you should think about adding an oil cooler. The motors flywheel pushes more than enough air to keep the motor cool all day ,even under high demand situations. The generators and cutting tools I use in the fire dept are put to the EXTREMES and we have not any problems due to over heating. MAINTAIN YOUR OIL REGULARLY and you will be fine.... would I lie too you?:thumbsup:

i got a honda clone that has some mods as of right now, it will do around 55mphs and when i'm done with it, its going to do around 80-100 so im looking to cool it down as much as i can and a tranmission cooler will make a big diffence since the oil will be circulating though it and the wind from driving will be hiting it and cooling it down, i've seen people use them and had the oil drop down 2-6 degrees

I have read this on various motorcycle forums and it has a use on certain vehicles. If this kinda thing is your style, wanting to add more stuff you machine, why not a remote oil filter and pump, then use copper lines.
Alot of the guys who do this sometimes bend the lines in a coil nearby or put in coils for an effect aswell as some practical use.

Overall just not necessary.

I personally would not suggest copper lines. Copper work-hardens easily, and the vibrations will cause cracks before too long. This is why copper tube is not used in automotive applications.

Thas true, it can. Id say you mitigate some of that by isolating some of the vibs by rubber mounting some of the lines and other parts.
An Idea..

Even "hopped" up kart motors built for racin dont have oil coolers because you simply dont need it. 2-6 degrees? You want to spend big coin on an oil pump, cooler, oil lines,ect, and then tear motor apart to weld up some spigots to drill and tap, then then fab up said re-circulatory system that will just add more weight and complexity to the kart? It just NOT worth a couple degrees..... your not gonna get a performance boost or "save" your motor any ...... Well when you FINALLY get it all sorted out and built, post pics and a performance and temp reduction results. Maybe you can prove me wrong......

I'm kind of curious if a 20hp clone would end up being a ticking time bomb to begin with as well as a 80 to 100 mph kart being a stretch. I will say this, if you plan on making land speed records with a kart you may want to invest in some safety gear and not so much on an oil cooler. Its an air cooled engine, you would do more for keeping heat down by jetting on the rich side to prevent lean seizure, detonation, and valve melt down.
