Arny Posted February 5 Share Posted February 5 Hi all, I was wondering if anyone has a detailed view on how Mack factory-installed the breathers on the RW cab. There must be some kind of reinforcement bracket on the inside of the cab. Would really like to know what it looks like originally and where it is bolted (or even welded) to. On mine they were retro-fitted and unfortunatelly they dind't do such a good job because the small reinforcement bracket they used made the weld seam of the cab, just above where the breather is fitted, burst 😞 I also noted that there are brackets available in Australia but I'm pretty sure it's a whole different design because the breathers on the australian Superliner do sit a lot higher (see pics attached) 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75128-dual-air-breathers-on-rw-models/ Share on other sites More sharing options...
mrsmackpaul Posted February 5 Share Posted February 5 The Australian Superliner used a normal R model cab, the U.S. Superliner cabs are different than a normal R model cab Maybe the cowl area is stronger on the R model cab than the Superliner cab Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75128-dual-air-breathers-on-rw-models/#findComment-568651 Share on other sites More sharing options...
Lmackattack Posted February 5 Share Posted February 5 If I remember right on the factory installed dual breather RW I Drove it had a reinforcment bracket on the passenger side similar to how the drivers side is. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75128-dual-air-breathers-on-rw-models/#findComment-568656 Share on other sites More sharing options...

I fixed one one time that they used nothing but fender washers. I don't think the truck owner owned the truck more than about a month before the top mount broke the sheet metal and he had to secure it with bungie cords to get home. All truck customizers and chrome shop guys are hacks 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75128-dual-air-breathers-on-rw-models/#findComment-568659 Share on other sites More sharing options...

Most likely it's the same - a picture from the drivers side would also help a lot. Luckily because of the vent on the drivers side the cab is much more sturdy in that area so it didn't do any harm to the weld seam yet.

mrsmackpaul Posted February 7 Share Posted February 7 And I only took a photo of the left hand side as I thought that it is probably the one not normally fitted but can photos of the other side if needed There is quite a bit of reinforcing in behind the panel Even out side, the bracket for the can has bolts through the cowl up top So 4 bolts and little to no reinforcement would definitely not be strong enough Put a couple of hats up high and things change very quickly with the loading just from the wind Maybe check out my videos when I put all the new cowl and that on, there maybe more information there A few hours of ribbish to fill in your evening Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75128-dual-air-breathers-on-rw-models/#findComment-568767 Share on other sites More sharing options...
Arny Posted February 9 Author Share Posted February 9 Wow thank you very much for the pictures! The R Model Cab does look quite different in that area than my RW Cab Quote Link to comment https://www.bigmacktrucks.com/topic/75128-dual-air-breathers-on-rw-models/#findComment-568900 Share on other sites More sharing options...
Arny Posted 21 hours ago Author Share Posted 21 hours ago Does anyone have a US/Canada RW with factory installed breathers who could support with additional pictures? Would really appreciate it.
