Case hydraulic drive cooler.

Kinda odd looking but sure would cool the fluid down. Neat idea. He said in his video that it cools the fluid down 25 degrees on a 100 degree day.

When I was custom haying the PS on the 400 got worked overtime with the 8 bale grapple on the loader. PS was separate unit. Used an transmission cooler in front of the radiator on the return line. Made a big difference.

None of the Case GTs Ive had ever seemed to have a problem with heat... hydro lines would be warm on a hot day but never to hot to touch.

 

[Propane1]

I measured my 224 once or twice back a few months ago when I was cutting grass. If I remember right it varied 120 to 140 F. Apparently it could get to 160 to 170 F, I read some where.

I could see 120F on a really hot day but above that I think might indicate poor flow through the radiator... I would try flushing it with CLR and see what kind of crud comes out of it.

Lance you have to take into account the guy with the additional cooling might be it Texas or Az where day time temps are regularly 90*F plus big difference for us here in the northern latitudes, I've never worried about the Case oil temps either but I have noticed that the low end hydros used in the average lawn tractor definitely loses performance on hot days if the hydro isn't kept clean of dirt and grass clippings
Hi Noel yes that will definitely reduce the temps on one of my airplane engine it had no oil cooler and on 80*f+ days the oil temp would go up never to red line but more than I liked to see I install a fined cooling sleeve on the oil filter and it did about the same bring the temps down
It was similar to this but just used a worn gear clamp to hold it on

That neat Gary. Wonder what transfers heat quicker. Aluminum or copper.

Noel

 

[Lance Skene]

On a low end machine I could see having heat issues but not with a Case HyDrive... those are very robust units so they arent really working very hard during normal use.

Aluminum transfers heat faster which is why its commonly used for heat sinks.

 

[Propane1]

I could make one of those heat transfer things out of sheet copper fairly easy. Or soft copper tube, or a combination of both. May not be as good as aluminum, but would still work
No oil filter on the Case 224 any way.

Has the rad ever been painted??? that would certainly reduce its efficiency.... and I still think flushing would be good place to start.

A little on the end loops of the cooler Lance, where some one sprayed the tractor once, can’t see anything on the fins.

Noel

 

[Lance Skene]

I dunno Noel but something doesnt seem right.... when I had the 448 with a hydro tiller even that didnt get hot running on a fairly warm day.

 

[Propane1]

lm hoping to change the oil in the spring Lance. So I’ll look into farther then. Take the rad right out and give it a good cleaning inside and out.

Are we talking about the radiator in the steering tower? I've never checked mine to see if it has any debris in it. I have an Ingersoll 3014.

Hydraulic drive oil cooler/radiator. Mine is in the front of the tractor. Like a cars radiator.

Noel

 

[chieffan]

In other words a transmission cooler. All built into the bottom of the radiators now.

 

[Propane1]

Ya. That’s it.
