noteven Posted December 6, 2015 Report Share Posted December 6, 2015 What Scrap said about brakes / forces / rusty attachments sometimes failing If you can decelerate a 80,000lbs truck from 60mph to 0 in 400ft would that take the same HP as accelerating it from 0 to 60mph in 400ft (i.e "a lot"?)

rickeieio Posted December 6, 2015 Report Share Posted December 6, 2015 What Scrap said about brakes / forces / rusty attachments sometimes failing If you can decelerate a 80,000lbs truck from 60mph to 0 in 400ft would that take the same HP as accelerating it from 0 to 60mph in 400ft (i.e "a lot"?) Same force required, but spread over many more axles. As to Scrap's post..........The exhaust is behind the bus, not plumbed into the passenger area. So, if the nit-wit drivers would turn off the motor while sitting stationary waiting for the kids to come out, old and young alike would benefit. And then there's the out gassing of the materials inside the new buses. Do you have a newer passenger vehicle? Do you windows look like the inside was coated with milk? Do you like having your lungs coated with the same stuff? Old buses don't have much plastic, and it likely did it's out gassing long ago.

Dollytrolley Posted December 6, 2015 Report Share Posted December 6, 2015 Call me a greenie eco freak, but kids breathe in half again as much air as we do, 25% more PM2.5 sticks to the insides of their lungs as ours, and it has been found many times over that there is 10-15% more PM (soot) in the air inside the bus than there is outside. Something like 70% of kids' particulate intake is just traveling to and from school. There are many ways to combat it but every time a DPF (or DOC for retrofit) makes head and shoulder improvements over all the other ways. So my opinion is to save the old busses to move inmates and haul Grandmas to the casinos, but if it is manufactured or purchased to move kids then a a new bus or a retrofit one is well warranted. My computer has no sound so I have no idea what they are all saying, but interesting that it happened upon braking. But I suppose that is the highest amount of axle torque in the life of a 250HP bus. Or I wonder if a backwards installed axle has something to do with it? Same force required, but spread over many more axles.

Imurphy907 Posted January 22, 2016 Report Share Posted January 22, 2016 They are calling the spring pack center pin a "tie bolt" So the center pin broke, and allowed the axle to move for and aft for a while, and Likely sheared the U bolt holding the Axle to the spring pack. 2016 Road Warrior 420 2001 Volvo VNL 660 Alaska Based.

GlennWest Posted January 23, 2016 Report Share Posted January 23, 2016 Uh, I was once an avid hot rodder. I broke the center bolt in my Camero diff and it slid foward. This was lifting front tires though. U bolts didn't hold it. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1 Link to comment Share on other sites More sharing options...
oscarvan Posted January 23, 2016 Report Share Posted January 23, 2016 I still say the reporter had no clue what they were talking about. I used to know very little about anything. Then I learned a trade. When I see/read news about my industry I realize they have NO CLUE what they are talking about. I suspect this goes for everything they report on.
