lawnmower exhaust

[hogasm]

We have a 0turn mower on the farm that the control cables are within an inch of the muffler. There seems to be a heat shield missing but the dealer is of no help. Issue is the control cables outer housing melts and the cables are done within 4 months of use.
I thought of wrapping the muffler with this https://www.ebay.com/itm/ESP-FLAME-G...ss!27948!US!-1
Any feedback would be helpful
thanks

ps....I have towed the mower with my van haha

You can't use silicone tape on the wire harness itself to insulate it near the muffler?

Dave I don't know. I haven't tried anything yet, but while waiting for the new control cables to come in I figured I would look into something that would either divert or control the heat from the muffler. The cables are only 1" from the muffler. Poor design.

Some of the stuff we use at work (Scotch 70 tape) can handle heat up to 500* then maybe add some of that automotive foil type tape on top of that? There is also header tape. It's what I did under my doghouse near my turbo/exhaust...wrapped the down pipe with header tape and covered all my electrical wires and wire harness with the other. Can't say if it's working but figured better than what I had before.

I use metallic header tape (the soft woven style metal, with adhesive backing) for welding, and it works great. NAPA stocks it.

I would think you could find something on this page, either to wrap muffler or protect the cables.

Try a simple radiation shield..bend up some sheet metal and place it between the cables and the exhaust (not touching either). If the primary mode of heat transfer is radiation (likely)..then that should reduce melting significantly.

I purchased an 18"x18" piece of soldering shield from the Plumbing Supply store. It is designed to keep you from burning down the house while soldering close to combustible material. I wrapped it around the muffler.
We'll see

Personally I like the idea of a heat shield, one that would provide an air space around the muffler that would position the cables far enough away to stop or reduce outer jacket damage.

Have you looking into better cables, ones with a spiral-wrapper metallic outer sheath? While not the least expensive route something custom-made might be the perfect answer.

I've used this outfit with good success: California Push-Pull Inc. Cable Specialists Based in Chico, Ca.. They were willing to do a one-off project, cost was far less than expected and delivery time within 10 days. They seem very knowledgeable about push-pull cabling construction and function so can be helpful with final design. In fact if you had a damaged cable to send them that might be a great solution.

Just an idea.............

In the theater we used a product called Zetex. It was a woven fiberglass fabric that we placed between hot lights and curtains. Check with your local theatrical supplier.
