Exhaust for Vanguard 16hp

3698 Views 13 Replies 8 Participants Last post by  Retk907
Anyone know how to find the right part number for a muffler on a Briggs Vanguard 16 hp engine? Looking at the Vanguard parts manual for the engine it lists multiple mufflers and even has an exhaust 1 and exhaust 2 section. Can't seem to find anywhere how to tell if my engine is 1 or 2.

Engine model/type number is 303447-0447-01. Code 94121311

There are usually multiple choices depending on what machine the engine is going to be used on. Perhaps the manufacturer of the tractor lists the correct exhaust parts in their parts list.

I think one would be hard pressed to find a Craftsman tractor with a horizontal shaft Vanguard. Or most any other horizontal shaft V Twin.

I was simply pointing out why all the variations of exhaust systems in the Briggs parts list.
Nothing in the original post stated what the engine was to be put in, or if it was just to replace an existing exhaust.
But thanks for your snark anyway

got a welder? can make your own exhaust i have done it on machines
When I installed a Vanguard on my Gravely rider I need the muffler on the flywheel side of the engine. I cut the exhaust flanges off the muffler that came with the engine, then welded on a short piece of 3/4" threaded pipe. Then using a couple of elbows and threaded pipe and 3/4" to 1" adapters, installed a pair of "pepper pot" mufflers. If you don't have a muffler at all, you can find the flanges on ebay

This post is in the CRAFTSMAN Forum in case you didn't notice.
The OP already noticed the variations if you had actually read the original post.
I responded that a horizontal V Twin in a Craftsman tractor means something is "non standard" and meant to elicit more details.

Found the source of my problem. The Vanguard engine on this tractor is from a Cub Cadet 1641. When the previous owner of the GT installed the engine he installed it backwards. Pictures I have seen of the 1641 shows the exhaust on the front of the tractor but this one has the exhaust by the steering wheel. I guess this explains why I have 3 reverse gears and 1 weak forward gear. Since there wasn't a belt on the tractor when I bought it, I just have to figure out how he had the belt rigged.

As far as my exhaust problem, no, I do not have access to a welder so I can't manufacture my own. I will just see what I can find out there in internet land that will work.

:tango_face_devil: That is a good one, how in heck did he do it?

I can only go by what he said but supposedly he raced it. The engine runs strong and will certainly be better when I clean the carb. Just going to take some wizardry magic to make the belts work.
Maybe he put a 1/2 twist in it?
Belt life would be short, but for racing, it probably isn't as much of an issue. You don't race to save money.
If the belt turns from vertical pulley to horizontal then routing (turning) it incorrectly reverses the direction. Neighbour gave me unit with a side drive peerless and mentioned that he had reversed the gears during a belt change.
Frankenstein is alive! I figured out my belt issue. Since the Vanguard engine's drive pulley is on the front of the engine and the engine is mounted backwards to fit on my GT6000, everything is in reverse. I had to switch around the two pulleys directly after the engine. I crossed the belt by the transmission so the counterclockwise motion of the engine pulley matches the backwards spin of the transmission pulley. Now I have 3 forward and 1 reverse like I should. I may have to put on a shorter belt or a larger pulley on the engine. In 3rd gear the belt slips for a few seconds the she goes like crazy.

Now to figure out why gas pours out of a metal tube on the carburetor after running for a few minutes. I know this is not technically a Craftsman issue, but if anyone has any ideas I am all ears.
