Busy day today...
Straightened out all of the hinges, replaced all missing carriage bolts for the seat boards and tightened the rest, then installed six brand new clevis pins for my troop seats (all were gone when delivered...but later found as swollen, rusty pulps behind the rear seats). It's nice being able to actually sit back there now, or just at least be able to fold them up out of the way when not needed. All of the ring pins were still in good shape and the ARNG unit that had it last were trying to using them to replace the clevis pins...
Replaced the mysteriously missing side marker light. Truck hasn't moved once since delivered, yet my marker light went missing...can't honestly tell if it was an odd thief or if I had a terrible memory lapse, as it WAS the marker light I was working on last...
Set new rivnuts into the windshield frame to support the handrails. ARNG again took a shortcut and used wellnuts here instead of rivnuts. Unfortunately, this means the oversized the holes, so the rivnuts just barely grabbed on. While I can't even get them to budge when trying to force them free, time will tell if they're actually going to hold. If anyone has a lead on 10-32 steel rivnuts that have an oversized expanding shell, please let me know...
On the new-to-me 200A Alt., UPS managed to drop the package and damage the fan shroud and the impeller fan, plus the woodruff key that was still on the shaft was in a bit ugly shape as-is. I replaced the impeller fan (without some kind of soft-jawed vice, this is very annoying...). I used a steel rod through the impeller fan and old fan guard to hold it steady, and also got out an impact wrench to get the nut off. Since the shaft will spin on you once it's loose enough, inertia is your friend. Just hit it in short bursts from the impact and it spins it off for a few seconds while all the mass on the shaft resists spinning up. Woodruff key just took more PB blaster, hammering with punches, and striking outward with cold chisels than I care to talk much about. We'll see if the anti-seize I applied to the new one makes that job easier in another 5+ years when it might need replaced again.
Last task was trying to recondition the scissor jack that I found in the back. It looks like it's never had a touch of PMCS, so the jackscrew was pretty close to seized and in generally poor condition. I lubricated the jack with a molyb grease that was at-hand and was able to manually turn it with the opposite side of the wheel lugwrench. The worst part of this one was holding the jack down somewhere to free-spin it until it was extended enough to use the weight of the HMMWV to hold the jack in place while I cranked on it with the folding handle (which also need much TLC). It's still not perfect, but it's definitely serviceable now and the moving parts all have a fresh coat of grease to help inhibit further corrosion. I'm thinking I'll need to degrease it, scuff it down with steel wool and maybe some emery cloth, then grease it all back up again to see if that gets rid of the rest of the resistance in the screw... I do know that once I get it operating smooth, it's not getting buried into the mudpit that is the rear seat bases again. It's going in the nice tie-down behind the driver seat so that I can clean it and regrease it any time it gets wet without it having to sit and soak for days...
