XM 818 5th wheel specs

[DOCUSN1]

Hi all I was wondering if any knew the specs on the stock 5th wheel that came on the 818 tractors. My truck is 1970 im looking for the drawbar specs and weights and any other specs for it. My other tractor came with a brand new holland kompensator 5th wheel with the stickers still on it. After seeing that I wondered if the old 5th was underated for severe use, the new one is B train rated heavey specs. Thanx guys, Mark

Probably depends on the rear axle capacity and mil requirements off-road etc.
My 5-ton has a 5th wheel rated 15,000 lb (45,000 lb total trailer weight).
