Side exhaust fan to control tub temperature

[woodlandfarms]

There is something to be said about picking your own used part. The utter grossness, the smell, the fact the car probably had a bunch of kids that went through the windshield.. Honestly, i really do love going to pick a part. really.

I had a friend that found a human foot under a dashboard back in the 70's when salvaging two dodge chargers to make one good one. YIKES!

Come to think of it, I had another friend that found a human foot in a shoe on a beach when she was a kid. Double YIKES!

I've never seen a car at that junk yard so mangled that I thought someone died in it. I believe they crush that stuff and it doesn't get out in the public yard. I'm actually surprised at how in-tact most of those cars are. However, I will say that they get picked over pretty quick and I'm surprised at how much damage the public scavengers do to other parts while extracting the part they need. But there's definitely treasures to be found there. :thumbsup:

I love your idea,unfortunately all the local salvage yards do not allow anyone inside,and parts are sold for year make and model,unless you know exactly what you need you might as well forget it

Look for one out of a Volvo 850, or S/V model (ie: S70, V70, S80, S90, V90) and get the relay harness with it (has a couple large relays to run high and low speeds with two trigger wires).

This company has many yards around the country. You pay a few bucks, get your hand stamped and you can go in and out as many times as you want all day long. The yard here is neat, clean and not muddy. I've had great luck there.

Search for an LKQ Pick Your Part junk yard near you | Cheap OEM used auto parts

Thank you for the link,a quick search there revealed no yards until i allowed searches from 200 miles away then I got 3 hits..that's just too far for me to go.

Looks like the closest u-pull-it type yard to you is in Binghamton...

2X Universal Slim 12" High Performance Radiator Cooling Fan Mounting Kit Black | eBay
I Just orded these 2 12 inch fans. for $40. I am not sure that i will use both or where or how I will use them but something is needed. Great price. i will let you know how they do later on my 428 PT i just bought. Having vapor lock problems and of course the tub heat i don't like.

I'm in the process of replacing the 10" fan added to the size of my PT428's engine cover years ago. It's been acting up intermittently, so I've purchased a 12" as a replacement. The fuel pump I installed after the OEM unit died is also misbehaving... I have the new pump, and it will be located a bit differently in order to avoid the high temps inside the tub. Finally, I have another 7" fan that will be mounted to the front of the engine cover right behind the seat. I need to weld up the mount for it, but it should push air into the front of the tub and help keep the temp down a bit. I'll post pics when I'm done.

I have the new pump, and it will be located a bit differently in order to avoid the high temps inside the tub.

I mounted my fuel pump by bolting it to the bottom of the right-hand fuel tank support bracket. This keeps it away from the warmer hydraulic components (like the PTO solenoid block) and the exhaust outlet.

I routed the fuel hose from the left side of the engine, underneath the intake filter cover, out to the bottom of the tub on the right hand side and forward to the fuel pump... keeping all hoses as far away from the exhaust manifold and hydraulic pumps and hoses as possible.

I relocated it first to the bottom of the left hand fuel tank bracket, but that didn't work as well.

In the FWIW category: I have used the aluminum back self stick foam to cover fuel lines to keep heat out of gas lines.
All the best,

Sorry to barge in after being MIA from the forum--except for occasional lurking. You guys have the best ideas! I added the little fan that Farmall140 references. Works fine blowing air under the shield and out the other side of the cage--thermostat controlled. Also added two heat shields on the exhaust: one on the header the other near the muffler. Using IR thermo the valve covers are around 200-210 after mowing on a 90+ day. The hottest area on the EH72 was the block between the cylinders with 250-270 depending on the angle I could shoot from. Running Mobil 1 so hopefully not cooking it. Valve job this summer showed no sludge or buildup under the covers. Change filter with Fram TG every year or 50 hours + additional oil change mid summer.




EDIT: Oops. Had my temps wrong above.
Before the fan/shield: -valve cover next to exhaust-- 200-210. After: 160 same as other side.
-top of engine block--245. After: 245
-bearing cover behind exhaust cross over-- 325. After: 250-270.
-oil pan -- 230. AFter: 230.

These figures are rough averages (+/- 5 degrees) that I noted.
Obvious benefit using the fan/shield for me, especially to the bearing cover just behind the exhaust cross over (am I calling that thing the right name?). I think the fan alone would help keep the little "Wobin" cool--it's surprising how much hot air is blown out of the exhaust side of the cage using the side fan.
