Default Brain Storming Oil Cooler
I am not an engineer or expert. I was brainstorming on putting an oil cooler on a k-series Kohler.
Looking for pros and cons...
Could I use a mechanical fuel pump to pump oil through an oil cooler?
Perhaps by placing an NPT fitting in the sump of an oil pan, route it to the "fuel" pump, then back out to an oil cooler, then from the oil cooler to an NPT fitting on the block?
One major question...is the pump strong enough for oil?

Again, just brain storming......

Unnecessary.
Not likely the fuel pump will pump oil anyway.
Nothing to gain.
Too much involved for no gain.

Why would you want to do this?

Run an 30 weight dino oil in it and it shouldn't have any problems. I use Kohler oil in all my K-series engines.

There is something wrong-not set right if the engine is running hot.

Default Thanks for the replies
I appreciate the feedback guys. No...engine running well. was just brainstorming. I think the best response was a lot of work with no gain.
Thanks again.

If you're gonna go through all that trouble you better add a filter.

A fuel pump wouldn't make enough pressure to push oil through a filter. I really don't think a fuel pump would pump 30wt oil at all..... but I never tried it. Even if it did, it's only a few cc's per stroke. 2, maybe 3 at most. It would pump so slow, you wouldn't need a cooler. It would cool just going through a steel tube 12"-18" long.

Big waste of time anyway.

It was a joke. You need to relax a bit.

It won't.. We tried using a electric fuel 12 psi pump with 5/16 inlet and outlet to transfer some oil. It started to pull it but as soon as it hit the pump it stopped.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
