3320 Vertical Exhaust Install (pics)

[WH401]

I know there is already a lengthy discussion on this in the Customization forum as well as in this forum, but I figured I would give you all my take on this anyway.

I have had the kit ordered for about the last 3 month's and finally decided to go pick it up and install it. The installation went fairly quick and was pretty straight forward.

The tool's I used were a drill, a 3 5/8" hole saw, never seize, sand paper, and various ratchets, sockets, and wrenches.

This is the old exhaust and everything left of the exhaust clamp will be removed.:


This the mark in the hood where you will drill the hole for the new exhaust elbow to come through.


This is the hole drilled and the new elbow attached to the muffler.


And finally, this is the finished product and what it will look like.


Overall it is a nice quality kit and a very clean install. The only problem I ran into was the supplied exhaust clamp that tightens the new elbow on to the muffler would not fit the new elbow. The end of the elbow either needed to be compacted, but this wouldn't allow it to fit onto the muffler, or the clamp needed to be reshaped. I just ended up reusing the old clamp as that was the quickest solution and there was nothing wrong with it.

So far I like it and it work's as its intended too. At first I had the stack facing forward but I was getting to much of the fume's in my face. I then turned it to the left and have left it like that ever since. In this position I get a hint of diesel on occasion but no where near like what I was getting with the stock exhaust. I may fabricate a stack that is about a foot taller to see if I can eliminate the fumes almost completely, but for right now it works very well.

IMO, if anyone buy's a tractor, new or old, this should be the first thing you do. Diesel exhaust is extremely harmful and why the manufacturer put's it down low is beyond me. Probably a design thing that make's it sell more, who knows.

Have a nice day.

Looks like the install went pretty smooth. Good job! I have a couple questions though.... Why did you install the vertical exhaust, instead of leaving it the way it was?? Also, did this change make it sound any louder to you (as heard from the seat position) after you made it into a vertical exahaust??

I changed it because with the OEM exhaust your constantly getting the diesel fumes in your face and I couldn't stand to breathe them. I couldn't stand the fumes so much I hadn't used the tractor in 3 months. I love diesels and everything about them, except the exhaust, of the older one's at least. That to me is the only draw back of all the tractors on the market today.

As far as the exhaust note goes, no I don't think it made it louder, the engine itself still tends to make the most noise. Though, I did notice a slight increase in terms of the sound of the exhaust rushing out of the pipe, but nothing drastic at all. I thought it made it sound better in fact, but it's a sound you'll hear once and then not notice after that.

How do you open the hood with the stack on?

How do you open the hood with the stack on?

The stack comes off the exhaust elbow, (refer to pictures 5 & 6), that stick's up through the hood. Also on the bottom of the exhaust pipe, there are 4 slots that fit over a tab, (refer to picture 5, on the side of the elbow), that enables the stack to be fixed at 4 positions in 90 degree increment's.

I like that vertical exhaust. I had a 3720 and it would try to poison me with the exhaust fumes. Seemingly also, in cold weather the fumes would loiter in the operator's station and were quite noxious. I like the smell of diesel but have mild reactive airway disease and thus could not tolerate the strong diesel odor. This was one of my few significant complaints on the 3720, which I have now sold. I was concerned I could not fit the stack under a standard 6'8" garage door and this was my only reason for not going with it factory. Interestingly I just bought a 2320 tractor. It has exactly the same layout exhaust as did my 3720, but is indirect injected. I cannot discern any diesel smell except with startup, but every direct injected JD compact I have owned (4310, 3720 times 2 and 4520) had a real problem with strong exhaust fumes. Of these, the 3720 was by far the worst. The 595 I had and the current 2320 have none. Makes me wonder whether the direct injected diesel Yanmar's (and PowerTech's) are more problematic here.

You just pull it out with your hands, comes off with a little jerk-pull. It's fairly easy but on my 4720 it's a bit high and a little tricky to get leverage if you're standing on the ground unless you're 6'-5" or more. Heat-resistant gloves required if you have to remove it when engine is hot: it melted my neoprene gloves lol.

I can only speak for the 3320 as it's the only diesel tractor I have experience with, everything prior has been gas. Though I did drive a neighbors indirect injected 04' Massey 1428v and I still noticed the fumes, though not as much as the JD. The exhaust exited in a closer location to the driver and there weren't any obstruction's such as how the tires act as one on the JD. Where the exit of the pipe is can change your experience completely.

What was the cost for the exhaust?

I paid $289 + tax.

Just be sure to drop a can over the exhaust if left where rain can get to it. I find a plastic drink bottle with top cut off works great. I know, some dealerships have them sitting there open, read the manual.

Great minds thing a like. Grabbing an empty soup can out of the recycling to cover the manifold was the first thing I did after I installed the kit. Even though the tractor gets covered with a tarp, I would never want to risk the chance of water getting in there. I've seen various dealerships that never cover the stacks or the vert. manifolds either, makes you wonder what there thinking.

 

[nmu98]

If its outside, I agree to cover. Due to its location around plastic, does the up pipe have a hole in it at the bottom of the bend to let out water?

My 5203 has one, but it is not around plastic, or inside an engine compartment.....

I don't believe there is a hole, but I can't say I have really inspected the piece either. I'll have to take a look when I get a chance.

You know, I have not had a problem with fumes, nmu98, how about you?
I looked at installing the vertical exhaust but I have not noticed the fumes, even with the back window open

I get them at start up outside the cab when I have the frontier snow push on. Its such a high wall that it pushes everything back. I have not had a problem with fumes on the OS or cab model, but I operate in open fields. If you were in tight places, maybe even high weeds, I could see having an issue.

On startup when its cold, I ussually check bolts to make sure everything is tight, and it is pretty bad then. The garage or barn does not flow air, and for a new diesel, its bad. It tops my 5203 for smoke in the cold..... Helk, even some of the 25 year old IH's are better..... But they all have upward pointed exhausts....

I like the idea of this. I do not like the cost!

I just read this again.... Wouldn't it mealt if you dropped it on there right after you used the tractor.....??? I know the 5203 would not like plastic... One of my friends thought it would be funny to hang my columbia jacket off there after I brought it in from helping out my neighbor. It mealted right through....... And that was when it was 30 degrees outside......

I thought the vertical exhaust stacks were curved at the outlet. Shouldn't that keep the water out of them??? It seems ashame that one should have to put half a Campbell's soup can on the outlet of his tractor exhaust to keep the water out, on a machine this expensive.

Yes, the top of the stack is curved, but that doesn't mean water can't get in there. Water has an interesting ability to find its way into the most unwanted and harmful places and this debacle just comes with the territory of a vertical exhaust stack.

I'm not trying to be rude, but honestly I don't really see your point in the problem. John Deere already offers a system that protects against water penetration, but the problem is that it kills you faster. Since I added this as an alternative to the OEM option, I have no problem covering an exhaust manifold after every use if it lessons the amount of exhaust fumes I breathe.

You can't have your cake and eat it too.
