GlennWest Posted August 29, 2020 Report Share Posted August 29, 2020 Just had a cab bag fail that is only 3 years old. Stayed crushed mostly for a year. So seems this may have caused early failure. So how many block up cab so as not to crush bags?

Chad Heiser Posted August 29, 2020 Report Share Posted August 29, 2020 I used to loose a cab air bag about every year because of them sitting empty and folded over for extended periods. I thought about blocking the cab to prevent this, but ended up building my shop that allowed me to keep the truck inside and connected to shop air. This allowed the air bags to stay aired up and I haven’t lost an air bag since. If I hadn’t done this, I probably would have done the blocking. I did get pretty good at changing cab air bags though. I could have it done from start to finish in about 15 minutes. I had to do it at home usually, but on occasion had to do it in campgrounds as well. I’m glad that is behind me now. I probably would have come up with some reminder on the steering wheel or something to remind me to remove the blocking before I hit the road. Knowing me, I would have driven down the road and spit blocks at following vehicles if I didn’t. 😉 Quote 2000 Kenworth T2000 w/ Cummins N14 and autoshift 2017 DRV Mobile Suite 40KSSB4 with factory mods, dealer mods and personal mods - now in the RV graveyard 2022 DRV Full House MX450 with customized floor plan 2018 Polaris RZR Turbo S (fits in the garage) 2016 Smart Car (fits in the garage or gets flat towed behind the DRV when the RZR is in the garage)My First Solar Install ThreadMy Second Solar Install Thread & Photos and Documents Related to the buildMy MX450's solar, battery and inverter system - my biggest system yet! chadheiser.com West Coast HDT Rally Website Link to comment Share on other sites More sharing options...

tyates007 Posted August 30, 2020 Report Share Posted August 30, 2020 (edited) I was the same as Chad. My T2000 ate cab air bags. I always place blocks. Between the cab and the frame when sitting. I have not replaced a bag in the past 4 years since I have started this. I use a 4x4 block cut to length. Just remember to remove them before traveling or they can really get stuck under the cab. Ask me how I know 😳 Edited August 30, 2020 by tyates007 Spelling Quote Link to comment Share on other sites More sharing options...
Jaydrvr Posted August 30, 2020 Report Share Posted August 30, 2020 That must be a Paccar thing. I've never considered blocking up the cab on my Volvo and my cab air bags last 5-7 years. I do know, when you take them out and look at them, they have built in internal stops, which they rest on when the air drops too low. So, you never see them really collapsed. Maybe that's just a Volvo thing? Jay Quote Link to comment Share on other sites More sharing options...

Nothing obvious to damage them, but nothing to stop them from getting full weight on top of them.

Hot Rod Posted September 2, 2020 Report Share Posted September 2, 2020 Just from some related experience in the lowrider air suspension business in past years... many air bags are available in the same configuration, but with or without the internal bump stops. No bump stop allows a little more travel, with a bump stop the bag won't collapse all the way plus it keeps the bag from bottoming out hard on a bad bump. I don't know if the cab air bags are available both ways, but a knowledgeable counter guy with firestone book shouldn't have any problem figuring that out.

GlennWest Posted September 2, 2020 Author Report Share Posted September 2, 2020 (edited) It was Firestone bags I took off. The ONes I got from Ranseys were no name. And I blocked up cab so they don't crush.
