Well I got into this project last night, pulled the bottom protective plate off while trying to get the fan shroud off. There were some troubling views underneath the truck looking up after removing the protective skid plate thing.
1. This piece of metal on the passenger side of the frame to which part of the stering linkage is bolted is curved/wavy (and of course rusty). Am I correct in saying it shoukdn't be this way ?
2. There is some sort of hose/pipe metal holding piece which came loose such that the hose which it was retaining is now chafing one of the drive belts. I think I can see where it should be mounted, but it doesnt seem like it is a bolt that I can undo, put the mount under, and screw back in. This is underneath on the passenger side.
I think this hose/pipe is part of the cooling system, but it appears there is an oil leak there too ?
Any thoughts on how to re-fasten and where this oil leak could be coming from ?

Yes, there is a bolt for this...it might have fallen out or came loose. it is the stabilizer for the return hose on the radiator. Ill shoot over a photo of mine...can you circle the other item you are talking about? it might be the front stabilizer that you are referring to....??

Thanks alot for the info. This is very helpful. I think the bolt came out as I could see where it ws supposed to go yet didnt feel a bolt. How could it have come loose ? Where is the closest source of an oil leak to that ? Btw, you have a nice clean looking rig !
As for the pic of the bent metal, here is where I meant:
Thanks!... as for the bend, it might be from the steering dampener that looks a bit rusted out... just a possibility. I would look at replacing that if you can.... the oil leak(if its oil) could come from a number of sources. I would start by checking any hoses from underneath... hit em with a good light source...you might be able to track the leak back to the source, I would look at any hose that has residue or fresh looking material on it. To many options at this point... try to narrow it down.
Swap this out if you can. Hit me up if you need help, I did mine about a year ago.

Ah that is a relief to see that yours has a bend as well haha. One less thing to temporarily not worry about (wait to do a frame off once I get a more permanent garage). I gotta get that bold holder setuo and the leak squared away though. I cant tell if it is antifreeze or oil. I kind of hope it is antifreeze.

What exactly does the "air pump" do on a 2F FJ60 ? I've never heard of such a thing on other cars I've had. Just wondering because it looks like I will need to move it around to tighten the water pump belt on my rig which is extremely loose.
Air Pump, aka Smog Pump. Very common. Basically it injects clean air into the exhaust stream to provide oxygen to drive complete combustion of HC and CO. Yes, the Air Pump is also the tensioner for the water pump belt.
Yes, there are actually three bolts you need to deal with (assuming you still have everything you're supposed to have).
Loosen the nut on the back of 17314A. This is the pivot point. Then loosen 90109-08038. This bolt threads into 17317 and locks the pump in place. Order doesn't matter so much, but both need to be loosened before trying to adjust tension. Then adjust tension with 90199-08264, left to loosen, right to tighten. Reverse order to lock it back down. You want the belt to be tight enough to drive the water pump without slipping, but not too tight. Too tight can wear out the WP.

The diagram is from the Air Pump page in the BJ/HJ/FJ60 parts fiche. The one that SOR has on their site looks like maybe it's for the FJ40.

This is insane ! I am a newbie to this I admit, but I couldnt figure out how to get the fan shroud out as one piece without removing the radiator. After basically pulling out the front end, that I could remove the fan from the clutch to make this easier.
As for the water pump, I cant remove the fan clutch because the belt is so loose. How exactly do I access the nut on the back of 17314A without removing a hornets nests of hoses and the water pump ? Seems like 17317 is missing as is 90119-08264. whoever put this belt in before really screwed me.

Dare me.
The shroud can be removed without removing the radiator, but you have to take the fan and clutch assembly off first. Which....
Yeah, you're missing the tensioning hardware. I can't tell you exactly how to get to the nut on the back of 17314A, but it can be done without removing all the hoses behind the pump. You'll have to do part of it by feel and figure out the right combination of extensions and drivers from the tools you have. It's probably either 12mm or 14mm. Make sure you have a wrench on the the bolt head also or it'll just spin. You might try just loosening the top bolt first and see if the pump will pivot. It also will be easier to work if you go ahead and take off the PS belt.
Once the pump can pivot, you'll need to find something to brace a lever (read: long screwdriver) against to tension the pump. I haven't had to do this before so I don't have advice on what to brace against. I know this isn't the mission you started out on, but you'll need to get it sorted before you can get the truck back on the road. That belt looks way too loose to drive the WP. Which could be your problem in the first place?
