Itinerant Air-Cooled

Colin or others,

Can anyone post some clear pics of the Heat tubes and their angles mounted to the engine carrier bar. I have 2 sets I acquired over the years and was thinking of finally installing them as I have the engine out, however when mocked up, between both sets, each side brackets are are different degrees of bent not giving me a definitive way to bend back into position. Also looking for how the forward end sits near each heater box.

Still not sure if these are worth putting on or just cosmetic over purpose? Any other thoughts? Are they in the way for checking valves or other access? I know the (assumed) purpose for them, but they seem to be rare in practical application. Samba has limited info on them, and now that the search function is disabled even tougher to get any info.

Colin you had 1 descent pic of the driver side from your shift spring thread, any more close up pictures?

I installed a set this summer as their purpose is to dump the hot air from the heat exchangers out the back instead of under the gas tank. Yes, I boiled the gas in the tank this summer in 110F heat in Eastern Washington. Vapor doesn't burn in fact the engine shuts off.
So yes they are great mod to do if you have a set. I used a 2" SS flex instead of the paper tube to attached them to the heat control valves.
Pics are not on my traveling laptop but they should be here on this site. The placement of the brackets is oblivious and with a little bending everything should fit fine. The dump tube ends face down and fit under the bumper.

Know what threads you might have them on? No way to search for pics on this site (that I found). Neither did your user name and "heat tube"

No, but really once you hold up the pipe correctly with the end pointing the right way its obvious how it mounts to the engine bar bracket. Yeah you will have to adjust the tabs so everything lines up but no big deal. I can't find where I put the pics either....so I'll post some when I get back in 3 weeks to Seattle. I am in theNetherlands now visiting and part sourcing!

They are in exact line with the exchangers, i.e. 3* tilted. I did saw the right tube slightly shorter along the bottom to give the dump air more room to disperse downwards.

Exactly what I needed, thank you

Is there a light in there or just a permanent aura from the underside of your engine?

Yeah, that is just the reflection of the halo.
