Fixin up the 782
 

The 782 got some new parts and fluids. New coil, points, plugs, wires, point saver, oil/filter, hydro/filter, and 2 turbo blower fans. She is running great. Next this winter is to get the deck rebuilt and a new paint job, and I hope hydraulics for the front.

Looking good Nightow1 :ThumbsUp:

Is that a Series I or II? And I'm curious about those turbo blower fans, where did you get them and do you have them hooked up to a timer or something?

Oh yeah, and great looking machine!! :beerchug:

Nice lookin' 782. I'd guess a Series II going by the oil fill tube. Could've be changed out and put on a Series I though........:bigthink: :biggrin2:

Yes it's a Series II, and the fans are just on a simple toggle switch. I turn them on when I run the engine for a long period of time. I added the blower fans because I use it on my puller and found them to work great at keeping the engine cool. So i thought I would try it on the daily worker. It works great after mowing for over one hour my oil temp read 151. I'm happy with that. I got them here

That is a sharp 782. If that is all original paint it has been well taken care of. If I can ever get my hands on a 782 hope it's that nice, or at least turns out looking that good. A 782 is what I learned to mow on.

Which way do your fans blow? If they blow toward the rear, they will be fighting against the engine fan. :bigthink:

They are blowing back, but I haven't noticed a problem.
What should I look for, and is it something I should be worried about?

Yea she is a great machine. I plan on a new paint this winter. I don't care so much about keeping it original I want it to be a worker. That being said, I would like to keep it looking as much factory as possible.

I'm sure you haven't noticed a problem. You must not have also noticed there is a fan 4X as big at the back of the motor blowing air the other way. Kinda makes those little fans pointless doesn't it?

YUP, your auxiliary fans only negate that intended purpose of the flywheel fan.

If you want to keep the aux fans turn them around so they blow the hot air out of the engine compartment.

My thought on what the fan setup was for is when he turns the tractor off (or even lets it idle for an extended period) he could flip the fans on to help cool the engine off which given the propensity for thrown rods (the Series I has) I didn't think was too bad of an idea. Just my :TwoCents:

Edit: My thought also had the fans blowing out the front :biggrin2:

Well than I'm going to have to take a look at the engine, because I cant even touch the hood after running it for a regular mow. The big UNnoticeable 5" fan in the front doesn't seem to cool it down enough or at least enough for me. after installing the fans I can hold my hand on the sides and the top of the hood. even the coil stays cool. I know the engine isn't dirty, because I can see light through the fins + I keep my equipment immaculate. We have used these on our pullers for years and they have always worked great. I understand the concept of negating the big fan but the results don't lie. If my temps were over 290 before and 151 after install, something must be working right. But that's just MHO :bigthink:
I supose I can try and reverse them and test the difference, But I'm not sure it will have the same result.

Just a way to test which way the air flows without the fans, turn them off and start the tractor. You SHOULD feel air coming out the front grill of the tractor and after a short time it should get pretty darn warm.

And I'm curious, where are you getting your temps from? 290 does seem a little high to me but for an air cooled engine, I suppose it isn't too bad. But 151? BTW, is that block? Oil? Cooling fins? That leads me to wonder if your temp sensor is behind one of the fans that's trying to blow cool air onto the engine because I don't think 151 is warm enough for oil to reach its proper viscosity. Of course, I could be wrong, you're not doing it right if you don't learn something new everyday :biggrin2::beerchug:

Edit: And the big UNnoticeable fan is at the "rear" of the engine, towards the drivers seat blowing air from the driver seat direction out the front of the engine bay through the grill.

The plastic 5" fan under the tunnel cover is for the hydrostat. It blows air to the rear.

If your pullers have the "shaved" fan, then the electric ones probably do help on those engines.

I too am curious where you get those numbers.

I know what The plastic 5" fan under the tunnel cover does, I was commenting on a post from another member J-Mech

And no most of our pullers don't have shaved fans never use them it's not allowed in our club.

As form the temps I'm getting them from a Milwaukee Laser Temp-Gun, I borrowed from a local small engine repair shop.

The fan that J-Mech was referring to, is the "Flywheel Fan".... not the hydro fan.

Given that it's a surface temp gun, I'm guessing you're pointing it at either the tin work on the side of the motor with the side panels off or the actual side panels of the tractor?

If that's the case (the temps of the side panels with them on the machine), rely on those temps with caution because what I'm guessing is happening is the flywheel fan is blowing across the fins on the motor cooling it as it should and then the fans you have installed are in turn blowing that warm/hot air across the side panels. This would appear to make the temps of the side panels lower because, well, it is. Moving air, whether hot or not, cools better than non-moving air. What I think our worry is is where is that hot air from the motor being re-circulated to? In the end, the panel temps don't matter, they could be 100° lower with the fans than without but what we want to make sure of is that the motor temps aren't being increased as a result. Adding extra fans to aid in cooling isn't a bad idea at all, especially on these KT-17's, but you have to make sure they're working in sync with the factory cooling, not against it.

Ok. Well, I think it defeats the purpose of BOTH the engine fan, and your auxiliary fans if you point then at each other. I get that your using a temp gun, but your numbers sound unrealistic to me. Where are you pointing the gun? I have a very hard time believing that they drop engine temps by 139°. I'm with Sam, I'd say if you want to keep them, turn them around.

Great job on the 782, it's a nice machine!

Well moving on, didn't intend to make a entire post about fans lol take it or leave it I'm happy with it. I finally received the shaft for the #2 cart, I kinda like the Ag wheels on it. Now I need to blast her and paint. Hope to get to it next week.
Few pix of it .

Great pics of the 782 and #2 cart!

Not to ...:beatdeadhorse:... but do you have one of these in the engine? (mouse nest) That will make it run hot. Your 782 looks good by the way.

No not a speck of oil or dust on her, when I got it I went through and cleaned out every nook and cranny.

I know better than to start more than one project at a time, but it's getting cold here and I decided to start on my blade. I'm going sandblast it and give it a new coat of paint. Got it tore down this afternoon. Not in real bad condition considering it's been outside for 3 years.

nice cart and 782:beerchug:

Actually it looks quite good. The one I just picked up will push snow in its rusty state this year before I get to restore it during better weather!

Finished blasting the blade and all it's parts, good coat of primer. Now I just need to break out the old paint gun and get her a thick coat. I'm happy with the way it's coming along, can't wait to get it finished then I can blast the cart and get started on it.

That blade looks very well done, as well as the 782. I need to get to my 782 as well, but too many irons in the fire! Looks like you are making preparations for a lot of fun this winter. Thanks for sharing your pics and keep up the great work!

Looking good!

Looks great night owl. Looking forward to more pics and info

So If there is one thing I learned In the service is you learn from your mistakes. Man up and admit when you screw up!!! SO HERE IT IS.... I Placed the fans to close to the muffler, They are now slightly disfigured, ROFL well that may be a bit understated. I melted the :censored: out of them LoL. I guess I should of placed them on the top of engine like I had before on my pullers. Thought I would try something different. DUHHHHH. :bash2::bash2::bash2:

So go ahead and let the bashing begin, LoL :Explode:

Pic of the week.

It happens! :bash2:

Sure does, we all make mistakes.

Ouch, but it happens. We've all been there, and most of us will be there again :biggrin2:

Making mistakes doesn't make you a fool, but not learning from them does. You sharing your mistake might help to prevent someone else from making the same mistake. I think everyone makes mistakes...I made one yesterday and I think it is my turn to make another one today! If anyone claims to not make a mistake, then get a second opinion from his wife....unless he has duct taped over her mouth.:biggrin2:

Cub Cadet 123

Are we allowed to do that? My wive seems to think there are laws against using duct tape one her.

Only the 90mph rated ones.:biggrin2:
