Here's a 2002 T800 with 34,000 plus hours on the 6NZ Cat engine and 901,000 miles. Only repairs are one turbo, one air charge cooler, one radiator, one oil cooler, one water pump, and three starters and one front drop-in at 800,000, two clutches. One of the clutches I just installed this week along with an Eaton reman 10 spd. The internal cooler went out and dumped three gallons of coolant in the transmission. The suspension was rebuilt twice also. Not bad for a GVW of 105,500 daily. Truck Shop
