Bigdogtrucker Posted March 19, 2012 Share Posted March 19, 2012 What was the reason some B models have the tall piped air cleaners while some do not?Just curious as i like the look of the tall ones. Quote Link to comment Share on other sites More sharing options...
220cummins Posted March 19, 2012 Share Posted March 19, 2012 Its called a bonnet tube. On oil bath filters it was to stop water from getting kicked up from road and sucked into the filter. Quote Link to comment Share on other sites More sharing options...

220cummins Posted March 19, 2012 Share Posted March 19, 2012 I got mine from a parts truck I had purchased. It is aluminium. I sent it out and had it polished. They bolt right on. You just need a clamp on the bottom and top. Its an extension of the bonnet. Quote Link to comment Share on other sites More sharing options...

You just need a clamp on the bottom and top. Its an extension of the bonnet.There used to be a bracing assembly offered consisting of a collar and three arms attaching to the mid section of the riser tube. There is quite a bit of wind blast resistance against that tube at hiway speed and the support is needed.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Red Horse Posted March 22, 2012 Share Posted March 22, 2012 So i could just get the tube and it's a direct bolt on?Also,are chrome ones available?Like this-and I too would like to find a chrome one-at least the bonnet-at a reasonable price. Kind of hurts to pay 200 bucks for something made in china. Quote Link to comment Share on other sites More sharing options...
Rob Posted March 22, 2012 Share Posted March 22, 2012 Like this-and I too would like to find a chrome one-at least the bonnet-at a reasonable price. Kind of hurts to pay 200 bucks for something made in china. But what isn't anymore. Just today I had a Tektronix oscilloscope calibrated. This scope cost $16,000 last year new and the tag on the back: "Made in China".Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

fifth wheel Posted March 22, 2012 Share Posted March 22, 2012 Not a good idea to use steel (painted inside ok), but after the elements nonferrous, plastic, rubber in the intake system.FW Quote Link to comment Share on other sites More sharing options...

RonGood thought for the stack-I think the base is flared-I'll check out-In the back of my mind I think the tube is 4.5" I took the measurements a while back and e-mailed to a chrome shop in Syracuse-guy came back at...." $485 to start"!

The base tube was 4.5" but the hole in the air cleaner was larger. The last two inches of the tube were built up from aluminum "collars" which were pieces of aluminum tube with an internal diameter fitting the external diameter of each collar. Then the assembly was welded together nicely and this is what showed. It looked like it was home made but nicely done. A tree collision destroyed it so it was thrown away.Might be an option for what you want to do if you can't have the tube "swaged" larger on the end.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Freightrain Posted March 22, 2012 Share Posted March 22, 2012 I got mine from Matt Pfahl, was on Ebay when I saw it. Came with chrome stack and new top. I liked my big top better, as the one that came with it was the small rounded version. I'm thinking it was $150? Something like that. I wanted the tall version and it's not a std exhaust size.No braces on mine and it's not a problem for the last 5-6 yrs.Without the riser, if the passenger wing window was open too far it would bang into the lid when you opened the door fully. The lid had a good dent in it from years of that happening. Quote Larry 1959 B61 Liv'n Large......................

Freightrain Posted March 22, 2012 Share Posted March 22, 2012 That is the lid that came with my riser. Still have it in the box. Quote Larry 1959 B61 Liv'n Large...................... Charter member of the "MACK PACK" Link to comment Share on other sites More sharing options...
220cummins Posted March 23, 2012 Share Posted March 23, 2012 your bonnet is the correct one the newer ones are like mine. Both of mine that i wanted to used were rotted and to far gone to mess with. Quote Link to comment Share on other sites More sharing options...

Both of mine that i wanted to used were rotted and to far gone to mess with.220, F'Train--Both of yours look good. I would say mine is the correct bonnet-no rot, its solid but this old dog was a dump truck since day one and my guess is the bonnet caught its share of trees off road as it has a few dents in it. The flare at the bottom is 4.5" and the stub in the air cleaner is about a 4.25+/- Not the easiest thing to matchup. Quote Link to comment Share on other sites More sharing options...

I don't know if its the original production air cleaners vs. newer reproduction ones or what? Quote IF YOU BOUGHT IT, A TRUCK BROUGHT IT..AND WHEN YOU'RE DONE WITH IT, A TRUCK WILL HAUL IT AWAY!!!
