RD 688 door hinges sprung / little white spacers

[raindog]

Recently, the driver side door hinges on my RD 688 log truck sprung to the point where the door was rubbing against the body panel and would barely close. There was an "event" that caused this--I was using the rear mounted knuckleboom with the door open (which I never do, but the latch had just busted), and that can shake the cab around pretty good, so the door was probably flopping around pretty bad.. So insult to injury I have to replace the door latch and the hinges.

I did try shimming the hinges, fiddling with the position of the hinge bolts, but when that didn't work I replaced the hinges. Everything's in good order now. No more running the knuckleboom with the door open.

The new hinges (and the hinges on the passenger door) have little spacers made out of some kind of high density plastic that slide against the inside of the hinge. After a while, I imagine these things wear out. Can they be replaced to keep the hinge tight and running smoothly? Or when they go does the whole hinge have to be replaced?

Our Rd has been like that since new. Rubs on the bottom corner on the driver side. Mack said it was normal....

Probably can buy an after market hinge repair kit for them. Depending on the type of "plastic" it could out last the unit. Maybe give them a shot of silicon spray to keep the plastic from wearing ? Paul

41chevy,

I think you're right. I'll give the hinge a shot of silicon spray every week to get as much out of these hinges as possible. Also, my local Mack parts guy says he'll contact the hinge vendor to see if the spacers can be purchased separately. If anyone is ever around Princeton, WV, the Worldwide Equipment Mack folks there will go out of their way to help.
