Exhaust Pipe Rain Cap

[MMH]

My B9200 has the exhaust pipe that goes strait up. The tip is cut such that the exhaust pipe opening is perpendicular to the ground. When rain falls the slightest breeze will allow rain to drop in the pipe. My tractor is parked outside & I try to put a coffee can on the pipe when I'm not running it. Is this necessary? Would the muffler keep the rain from running into the engine?

Definetly not, get a flapper cap for it, you'll forget the can one of these days and next thing your engine will be full of water.....Mike

The ole coffee can has been used about as long as there have been tractors. As kids, for entertainment, we always watched to see how high the D-John Deere would blow it into the air when the first cylinder fired.

You could cut the pipe square and add a rain/weather cap and in general they do a good job but the can is a sure thing.

The muffler won't stop the water and water in it will surely make for faster rusting out.

If this was my tractor I'd be covering a few other things like the instrument panel, steering wheel and seat. In the good ole days that wasn't necessary as the sun and rain didn't effect cast iron much.

The fun part was to try to catch the can on the way down (from the seat)! :laughing: ~~ grnspot

Some people don't like the sound of a flapper flapping, but with the noise any diesel tractor makes, the extra sound (rattle) of a flapper didn't bother me at all. I bought one for my B7100 at Tractor Supply Company where they had a variety of sizes.

That is my concern. I do put the coffee can on, but sometimes forget. More concerned about rust than engine filing up w/ water.

I used to have a B8200 with same exhaust set up. I found a piece of tubing to fit over the pipe, bent a 90 degree curve in it and cut tubing off about 2" beyond the curve. No pictures, sold the tractor.

I've used the flappers on the big tractors and automatically picked one up when I got my little Yanmar. The pipe is at eye level and close and I was getting sick from the exhaust. I took it back off and have no problems. I park it in the shed but keep a soup can on standby if I get caught out in the rain.

My LS is the same way with a 45 degree bend and then a 45 degree cut. The bend starts below the cab but ends above it. I dont think I could just cut it straight as then it would likely put the exhaust right into my cab windshield. Since I shed mine all the time, I am not concerned with it, but I would think that the manufacturer would take that detail into consideration and make allowances for it setting outside. They may have some sort of drain hole in the muffler like car mufflers do to allow any accumulated water to leak out. Unless you hit it with a fire hose, it shouldnt get a lot of water in it anyway, certainly not enough to flood the engine unless it was exposed to another NOAH's flood.

I never had one on a compact tractor, but I would think you'd never hear the flapper if you kept the RPM up about a thousand.
The old Deere compacts (670, 770 and 790) exhausts had some kind of rain trap. Not sure how it worked...read about it in the service manual, IIRC.

That's true, Roy. If you keep the RPM up, you won't hear it, but I don't remember how high it had to be. It's not just a rattle from closing and hitting the exhaust pipe. The hinge has enough play in it, I assume to be sure it always falls closed when you shut down, so that hinge rattles a bit.

The bent, slant cut pipe has been effective on all my tractors. In an accumulated 40yrs on the ones that sit outside we have not the slightest indication of a problem. One of them tho aims straight forward. When its trailered it gets capped.

I had the opposite experience with the bent and cut pipe on my 450 Case. I always put a can over it, but one time my son was using it and forgot to put the can back on. The dozer sat for about a month at the woodlot before I went to use it again, after a couple of driving rainstorms. First thing I noticed was no can on the stack. I cranked it briefly and no go (it usually fires right off). I checked the dipstick - oil level was UP. (I had just spent over $3000 on a motor job.) I drained the oil - quite a lot of clear water came out first - and changed the oil filter. I then said a prayer and cranked her over. It took a bit of spinning and some crud came out the stack before it started to fire, one cylinder at a time, and it finally smoothed out. How do you spell relief? I immediately installed a straight stack with a rain cap.
It's been close to 10 years since that happened and the little crawler still fires right up and works great. I think I dodged a bullet on that one.

No doubt unfavorable circumstances can add up; amt of time idle, # and intensity of storms&orientation to storm winds, grade angle, exhaust design, etc. Glad you were able to "extract the bullet"! :thumbsup:
