i'm on the heavy load low boy cargo bussiness...now i'm handling load with a gmc brigadier prime mover fitted with follow configuration
engine dd 8v71 (318h.p.)
allison ht750drd (23.96-1) on 1, according to allison specs
dp21 eaton ( 6.17-1)
275-70-22.5 tires
i will like to explore the posibility to replace this unit with a consolidated m123a1c with the follow configuration
engine cummins (300 h.p.)
mack trdx720 ( 12.97-1) at 1 low
mack end 65,000 rated 10.11-1
14 x 24 tires
pulling weight always goes over 300,000# of combinated (load + 4 axle + 3 axle boogie all on 12.00 x20)
so far gmc achieve the goal. however component start to worn and a replacement time is comming soon
so basically the question are:
1) if m123a1c with clutch will have at least the same capability to take off on hill as gmc
2) if m123a1c drivetrain will fail (break) under such condition
3) comparing oshkosh m911 drivetrain (same rear end as my brigadier) with mack m123a1c one..witch one will fail first???
