JTL, you forget how the rear axles would snap the drive lines and finals when they were worked in four wheel drive. As ALCO says, the nightmares were almost gone!
Hjolli. a 773B with the traction control system would go anywhere these would go and do it for thousands of hours and whole lot less money. If you wanted ten Haulpaks hauling on a job, you better start with fifteen.
John C, you are right! Although we havent too many finals fail, I cant recall how many drive lines we have replaced over the years. I've seen drive lines break running down the haul road! They have a knack at tearing out transmission and hydralic lines when they go.
I've said it before and I'll say it again, they arent a bad truck, but they arent a good truck.
On a job where we are running 4 Payhaulers, we always have at least 2 sitting on the ready line.
I get a huge kick when we call the hall for Payhauler drivers, and no body knows what they are! I dont how many times a person will come out and work one day, and not be there the next! They are not a operator friendly machine!
