Donald Holbrook Posted March 7, 2022 Share Posted March 7, 2022 I bought a 1985 R688ST sight unseen from a man I met at an auction. Turns out the truck had been laid on its side. I have tried to adjust the hood and have gotten it squared up with the cab,but now it’s about 4 inches away from the cab. I think maybe they replaced the hood with a hood off another truck. So my question is how do I align the hood is there a procedure, and is there different hoods that will fit that truck?Also I put an eyeball on the cab mounts and it look like nothing is bent and cab bushings look good.

There ARE, indeed, 2 different R600 hood lengths. Early is 52.5", I believe and the late is 54.25", or somewhere thereabouts. That's only about 1.75" difference, though. The hoods attach to the radiator supports at the front. There is some adjustment there. Older ones had rods connecting the top of the radiator to the cab. These could affect the way the hood fit at the cowl. I think yours is different than that, though. I'm sure somebody on here can help you with the details. Oh, and welcome to the Dog Lot! 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

mechohaulic Posted March 9, 2022 Share Posted March 9, 2022 far out thought , by chance is that an air ride cab and bag is not filling. that would give extended space.

mechohaulic Posted March 9, 2022 Share Posted March 9, 2022 "eye ball on cab mounts " might be front mounts . don't know if this unit has been running with air built up . hood was changed possibly the rear cab air bag (if there is one) was never hooked up . a deflated air bag could look like a cab mount.
