900 and 7100 heat shield

Recommended Posts

Chris727
I have a 17GTH-L repowered to a 16hp briggs, for years I was running one of those cheapie $5 mufflers on it, I have obtained the factory muffler but I need to make a couple items to install it. There was a large heat shield that went over the engines on the 900 and 7100 single cylinder tractors, its NLA and I think it looks relatively simple to make. Would anyone happen to know its rough dimensions? I can figure out where the holes need to be but am just curious of overall size. Also is it really necessary to have the heat shield? I guess it helps keep the hood cool. Thanks in advance. -Chris

RayS published a dimensioned drawing of the shield. Here's the link: http://www.simpletractors.com/club2/topic.asp?TOPIC_ID=84593&SearchTerms=heat%2Cshield I also repowered a 17GTH-L with a 16 HP single cylinder Briggs. I don't run the heat shield and with the vent holes on the hood, I'm not aware of any heat issues. I probably don't know what to look for that's a problem.

And I just saw your want-ad for the elbow that screws into the block. It's not special, I used a close radius street el (3/4" if I remember correctly). I got it at Lowes or HD, don't remember which. You do need the locking ring to position the elbow in the right place so you can attach the special pipe to muffler elbow.

Thanks Bill, I don't know how I forgot about Ray's heat shield, great post. I guess I was wrong about what I need. It is part # 18 on the diagram and apparently it threads into the street elbow joining it to the muffler. It is over $90 new:OC Funny they still make the pipe but the muffler is NLA.

Looking at several parts manuals I see tractors with Kohler engines have heat shields but those with Briggs engines do not. Were heat shields used with Briggs engines? If so, on which tractors? Thanks,

7116 (mfg #1691382) has a Briggs 16HP with the heat shield. I think some of the earlier tractors had a "double skinned" hood which would have the same effect.
