Paint burning off side of hood C-101

[dmoore 962]

So who here has had a problem with the muffler burning off the paint on the right hand side of their C-101 hood? What did you do about it? Thanks!

I have a B-100, not a C-101, but basically the same. I moved the muffler further away from the hood. Leaving a nice air gap will keep it from getting too hot.

Well if it's a repaint then maybe a higher heat temp paint. If it's stock then what I have seen on all of mine is the discoloration of the paint. all of my C's with the stock muffler has gotten so hot that the paint has turned a shade of whiteish orange. I have seen some that have been restored that have had a small heat shield put in on the inside of the hood. There is just not much room for all that heat to dissipate.

Option 1: They make various types of foil reflective material you can put on the inner part of the hood to "reflect the heat".

 

Option 2: Wrap the mufferler with a header wrap material.

 

Option 3: Replace the muffler with a different style or straight pipe it.

I might investigate to determine if this isn't a case of the muffler running too hot because of a leaking exhaust valve in the engine.

Never had a C-101 but my Grandsons like the vertical stack on my 12hp Raider.

Like said above , if you're going to wrap it , get the Titanium & use the stainless ties .

It works great , but it will stink until it's burned in.

Thanks for all the replies...I want to leave it original looking...maybe I'll look into trying to reposition it a lil further from the hood...the mounting tab at the bottom of the muffler is elongated so maybe I can get a little more movement. Dave

I know a WH guru that made a heat shield out of a small pan (you know, the kind your wifeeee cooks your taters in)...it is a bit larger that the muffer but when painted red....well it looks kinda "cool"...come to the MO M&G in Sep and you'll probably see it!!!

I restored my c-121. I sandblasted,primed,and painted every component. All sheet metal was 3 coats of 2 Part epoxy primer,sanded between coats, three coats of red, three coats of clear . After all body work was done I ran the tractor 3 days later. Ten minutes after running the paint bubbled on the right side. This all happened the day before the W.H. Show . I had no time to fix so I brought it to the show. There I met Cecil Pond and asked him about this and he told me this was a poor design from the factory. I have several 78-79 c- series and most have paint damage on that side from the exhaust .

The hood on my C-121 was the same way, so when I did the rattle can resto I put a stack on it.

If it really bothers you, and you want to keep it stock. a 1973 c-160 and maybe others came with the smaller diameter mufflers, it is the same shape but just smaller witch would give you more space away from the hood side.

A thin sheet metal heat shield attached to the muffler will reflect enough heat away from the hood to prevent paint damage as long as their is some air space between both parts. work out a template with a piece of heavy paper and then transfer it to metal, Stainless would look good, attach it to the muffler with large hose clamps.

This type of thing happens when the paint doesn't dry properly. I recently restored my C-161 and did one coat of paint & primer on the inside of the hood, but 2 coats of primer and 3 coats of paint on the outside. I didn't let the primer or the 1st & 2nd coats of paint dry and harden property before applying the extra coats and 5 minutes after starting the motor, the paint bubbled ON THE OUTSIDE but NOT the INSIDE!! The paint under the hood right next to the exhaust stayed smooth and shiny. The paint on the outside of the hood with all the extra coats bubbled horribly.

I've not had any trouble on the C-101 or C-121 with stock exhausts after painting
