Exhaust exit on 7000 series

[hotrodtractor]

I have been parading around in the Harley tractor 7010 and I am (really my wife)getting tired of smelling like exhaust. The issue with the 7010 is exhaust discharges in hood (well that little hole). Please remember this will be my show/parade machine and I need to be clean... I don't want piles of clamps and flex tubes. Please vote on option 1,2 or 3. 1. I bought a exhaust setup off a 7116 which has lower discharge and better heat shielding. I think my best bet is to go to the 7116 style and run elbow pipe by front bumper like on newest sovereigns. All I would need to do is cut off elbow from 7116 muffler and attach the extended elbow from a new machine. 2.I know many have gone to stack pipes, I thought about that also but have heard noise is issue and then exhaust up by head. 3.The one other option I have considered is to add a longer discharge pipe off the factory 7010 setup (which is all nice new black heat painted). Rod Hubbard did this on his with a chrome pipe. I would make that pipe much longer and curve down maybe like a Harley pipe under the running board. http://simpletractors.com/Club2/topic.asp?ARCHIVE=true&TOPIC_ID=84885

Again trying to reinvent the wheel. Rod Hubbard solved that problem 10 years ago.

solved by adding that little chrome tip? I want to go a bit further than that

Single turn out chrome stack....I don't smell like the exhaust, nor do I smell it while on the tractor. Noise is suppressed with a stock briggs muffler inside the stack. Re-reinvention of the wheel...lol. This is just my take on it. Plus, it looks awesome. (imho) There is an inner pipe of 1 and 1/2" that keeps the outer pipe from bluing.

All 3 ideas should work, it would depend on which is easiest to implement.

Do you have a picture for #3?

[hotrodtractor]

for #3 I would imagine something like the picture but on other side and lower exiting under running board not looking for easiest or cheapest.. just coolest. this is a bling machine and want a exhaust that continues that theme.

[hotrodtractor]

zippo that is impressive.. love it. Just too tractor for the hot rod I think. I was just thinking it I did a setup like zippo but mounted down on angle toward ground and end up near bottom of running board, the take that tip and face at ground.

need a laker pipe under running board

[ZippoVarga]

In Harley terms, that would be a street sweeper exhaust. Maybe you could run the plumbing through the front of the frame, then put the chrome turn out on. Just a thought! I like your idea to make a laker type pipe set up like on the old hot rods.

[ezliving4ume]

Idea #3 tuck the pipe up next to the frame rail, and run it under the running board. do a 30 deg turn out to dump it right in front of the rear wheels. My two cents

[hotrodtractor]

hmm looked at this a bit more. Because the steering arm I will not be able to run low side pipe on that header side. I could squeeze between card and steering arm, but then it would be dumping right on my toes. I could move to left side like the 75th did but then that's a bunch of plumbing. Got the muffler from the 7116 today and that setup exits on left side (normally a hole in frame). I have not tried it yet but hope the 7116 muffler setup will work on the smaller frame 7010 Harley tractor.

I've have been playing with the idea of buying a pipe bender and running my exhaust out the back behind the rear wheels. Cuts down the noise and the gas fumes are behind you. The small exhaust pipe sold for these 4 cylinder cars nowadays would work good, could also weld it so it's all one piece.

I have no idea but would that create too much back presure? Its going from a small 8 inch pipe to 4 foot? Like I said, I have no idea but curious. Maybe a larger pipe would resolve it if ther is an issue?

[dave45056]

How about this... Chrome tip extension and modify your hood. My hood and muffler were modified by the PO... Maybe for the same reason.

I wouldn't think it would be anymore if not less back pressure than the two mufflers somebody here is putting together for a single quiet muffler.

[hotrodtractor]

I found my solution it involves 1 1/2 chrome drain pipe slash cut with a expanded threaded end and a stainless steel sink drain. Looks very slick will post a picture soon. No cutting done (minus the drain pipe), no welding no drilling and best of all can be removed if desired with NO damage. This worked out slick.... worst part was cutting the bottom off the sink drain strainer basket. You guys are going to love this, it's a little simple and basic for my taste but is a good start/hold me over.

[hotrodtractor]

here it is boys and girls... very modest but keeps soot off hood, exhaust smell off me and looks pretty cool also.

The escutcheon is a nice touch. The exhaust through a port hole always seemed a bit weird to me too. From an air flow stand point, it would seem to me and your gaseous odor would also indicate that when the unrestricted exhaust flow was shot through the trumpet bell shaped hole, the exhaust would tend to fan out. Although there maybe be some sound attenuation factor to this set-up, not to mention hood clearance issues as well. With a straight pipe as you've designed the exhaust should stay in an intact stream longer before dissipating. Did you tell your wife before you took it from the kitchen sink? :D

[hotrodtractor]

Funny I bought pipe just for this purpose. ^ Tommy you got me on the "escutcheon" (shield) word I have a masters degree and I had to look that word up to know what it was.... good one thanks for making me think. The tip did not change the sound much but did add a little.

[HubbardRA]

Interesting! This is the exhaust on my AC 713S that Maynard saw back in 2004. I used a trim ring from a sink drain on this one. Not quite as pretty as when Maynard saw it, since this has been my primary lawn mower since then.

This is the one I recently installed on my Simp 7125H that I am building.

[hotrodtractor]

funny how we come up with similar solutions/copy good ideas. I looked everywhere on this site for more info on the tail pipe mod saw Rod's post from way back butt did not have much for up close pictures and mentioned welding/brazing drilling painting.... scared me off. Thanks for the above pictures and information had I found this earlier things may have gone smoother. Darn I thought I was going to patent (as the originator) the sink drain ... but little did I know it was done years ago with a ring not a entire drain. hahaha Well I am happy with it and it's removable/simple....

[hotrodtractor]

hey Rod since your revealing secrets now how about some details about that gas cap mod... if you don't mind me copying or reinventing your wheel ^

Hey, if we all can't learn a new word every once in a while, we might just as well drive JunkDeeres. :D

Kevin, Are you talking about the aluminum plug that I put in the hole in the 713S hood? I did that because I was not using a Simplicity tank and the neck of the smaller one did not come through the hole. It is a piece of aluminum 1/2 inch thick that is machined to fit the hole with a 1/4 lip overhanging the hole on the outside. I drilled a blind hole in the center and threaded it to hold a strap that keeps the plate in the hole. Unfortunately it is not a gas cap that will fit a factory tank. You could probably machine an aluminum plug with a cavity in the center that would fit the top of a cap. It could either be pressed or epoxied to the top of a gas cap. I have an old lathe, so I made my own plug. How do you like the snorkel on my air cleaner? It is the end of the snorkel of a mid 60s Chevy V8 engine with a two barrel carb. I cut it off and welded it to the air cleaner, then filled in the joint with Bondo to give a smooth appearance. You may also like my dash plate. It is made from a sheet of polished aluminum, the same as they use to make plates for trophys.
