bts-4120

low range on the trans  was mostly for creeping off road and curb side pouring in a cement truck  you'll need the top 5 every time but the bottom 3  depends what you doing with the truck bet its at least for 5.73 gears  in it

He speced that Pinnacle wrong from day 1.

The guy is a quack and blames everyone and everything for going wrong. 

Unfortunately, it's like watching a train wreck...so I check in once and a while to see how many more poor choices he has made.

exactly but he knows everything,  I keep watching him spec super heavy specs to move 50 and 60k lb machines

it might have started life a just a company freight truck

There will be a redesigned Mack Carrier launched end of 2018-early 2019. The new carrier will go away from single bolt threaded into the carrier housing concept to providing a flat surface on top able to mount the V-Stay with 4-studs.

Is this other than M-Ride suspension (with V-Stay bolt stripping the carrier threads) you are talking about? What part of Mack carrier chunks are falling off?

pinion shaft failure and exiting the side of the housing  no air ride  pavement princess

I would go with a Manual e7  they are performers

yeah the one i had was heavy spec 44lk camleback 14,600 front

they made a ch 713 with the longer hood of a cl on it you could  make one fit in one of those

I've seen Mack chunks fail in on road applications never overloaded either.  Unheard of back in the day  I don't know whose building the rears for Mack now but they need to go back to the drawing board.

nope and why would you ever want to do that

shop labor rates killed the camelback  its a excellent suspension until you pay $100 a hr to replace the bushings or a cracked trunion.  The T ride is alot easier to work on with just as good articulation

the lr versions of the 13 and 18 spd mack   had a low hole  and reverse slower than the eaton which is nice how ever I heard Mack  trans. are on the way out except for the m drive  pretty sad  triple counter shaft design has been around what 60 years

All the talk about horsepower is nothing if you aren't building torque.

 

Racers saying:

Horsepower is how hard you hit the wall, torque is how far you take the wall with you.

in a big truck or tractor  I'll take all the torque I can get vs  all the hp itll make

550hp outta of 636 cubes working it everyday and it survives   interesting   manual E7 would be the way to go  and have a motor that you could get parts for  and keep running for a long time

for what your going to shell out to get 427hp you might as well shoot for 475-500  its  all going to cost the same  injectors turbo or a programmer

Mack put them in at the factory should not be that big of a deal

i  yeah that should do it unless the balancer might be diffrent.  if I was going that deep in the motor to do all that   you might as well freshen it up with a in frame kit  and new cam though

if it came with that 15spd  it won't be a 300 maxydine that's for sure  350hp and a fuller was most common but you never know you might luck out and have a 427

actually napa gold is a  baldwin filter painted white

I miss the mid roof option already

I heard they was using the wastegated turbo from a 12.7 470hp

M11   does not  have  the torque   a E7  does  but your showing up with quite a bit less  hp   so its a crap shoot  but a good 300 maxidyne or 350 would run over a 330 M11

limit is 300 trucks a year  Fitzgerald is building 500 hybrid hydrogen  fuel cell trucks for US Express  actually Ryder owns the trucks they are just Leasing them

had a couple  n-14s  much rather  have  my 427

 

Holy crap that is an RD hood

thats what I thought to  when I seen the clip.   how sweet to have a ch cab  rd hood 60" bunk

sorry for the slow reply  on passanger side of the motor it runs for the head down to a fitting by the unit pumps it tees  back into the fuel line
