Gradall XL4100 Excavator w/ twin 5.9's

[Ncostello]

The highway department at work is buying a used 1998 Gradall XL4100 truck mounted excavator for ditch work. They've got 3 old ones that are all junk now and basically worth scrap prices.

This one is pretty nice and was owned by another county. It was traded in for a new one. We're paying $50K. A new version of this machine is $350K.

The excavator portion of this rig is powered by a Cummins 6BTA5.9L 150HP-440TQ engine. Light years ahead of the old one we have with a 3cyl Detroit.

However the chassis is driven by its own engine for road driving. Its a 6BT5.9 (non-intercooled) with 200HP-600TQ as per the factory specs. An option was the 6CTA8.3L which the previous owner did not opt for.

The upper excavator engine was replaced at 4000 hours due to some oil consumption issues and the lower at 1300 hours / 30000 miles due a coolant leak that couldn't be figured out. Both by Cummins of Omaha and only a couple hundred hours on each now. Thats a good deal really cause 4000 hours is pretty low for the overall machine. The previous owner didn't mess around when they had a problem. They just got replacement engines and got it back on the road.

The truck tranny is a Fuller RTO-11908LL 10 speed forward/3 speed reverse. Top speed is 52MPH in 8th per specifications. LL gear will get you 3MPH. Clutch is a 14" single disk puller type.

I had really hoped it had the 8.3L for the truck portion. But it dont. Is the 5.9L in this application going to do the job OK? It was even offered standard for the 6x6 version. The machine is 45,600 LBS working weight. We don't have alot of large hills. But I guess all we can expect is slow anyhow. Thats fine. No need to speed in this. I just wasn't sure of the 5.9 with such weight.

I guess if it ever has a problem...we can always drop in a 8.3L or L10 or something.

PS: Would that Fuller work in a Dodge? Would be cool!!
