I started this thread in order to ask a few more specific general maintenance questions without taking another thread (about service manuals) off-topic. I was asking for help finding service manuals that addressed changing fluids and filters (oil, fuel, coolant, etc.). Recovry4x4 directed me to LO 9-2320-209-12-1, which was helpful - but I've got a few more questions.
For example, I know that changing the engine oil should be pretty straightforward, but I nearly missed the one diagram that points out the drain port below the oil filters. And the filters that I ordered from OD Iron included more seals than I know what to do with. There are two large seals (the diameter of the oil filter cans), but one is narrow and one is wide (I found a remark someone posted in an oil filter thread, saying to use the wide one). And then there's one small seal that I thought would replace the seal under the nut that holds the oil filters down, but it's too small. I guess I can't expect the TM's to answer all these questions for me, but I haven't found any good 'how-to' threads on this topic either.
In spite of all these questions, I'm making pretty good progress.
The axles are almost done: I've flipped the hubs, greased the bearings, installed new seals (except the the pinion seals because none of them are leaking), installed all new wheel cylinders, and changed the oil. Just waiting on some new wheel bearings and brake shoes for the front axle, then it will be back on six wheels.
I've changed the fluid in the transmission and drained the fluid in the transfer-case, but I just found out I need a new transfer-case, so that just turned into a bigger project. Anybody know where I can find a complete air-shift setup?
EDIT: FOUND A TRANSFER-CASE.
Drained the oil from the engine, and now I'm trying to figure out what those little seals are for so I can install the new filters and fill 'er back up.
Just found out that the drain port below the oil filters is seized. Looks like I'm going to have to siphon the oil out of that galley. I've drained the pan (both drain plugs) and removed the oil filters. Is there anywhere else oil collects? Reason why I'm asking is that I'm switching all the fluids over to Amsoil synthetics, so I'd like to purge all the old fluids and sludge.
The other important thing to mention (related to draining the engine oil), is that the dipstick read full, but the 5 gallon bucket that I've been draining into is only a little less than 3/4 of the way full.
EDIT: Adding more pics and questions.
I'm going to steam-clean the entire truck before I sandblast and paint it, and wanted to take some pictures of the condition that it was in. Partly to document the build-up, but mostly to poet here and ask some question about which of these things I should be concerned about. If you guys could let me know what I might need to do about any of these things, I'd like to tackle as much of this stuff as I can while I've got it down/apart right now.
The underside of the hood is developing a heavy film of oil, back toward the hinge.
Pretty sure this is no big deal, but looks like an easy fix. Gasket or RTV?
The whole driver's-side of the block is a little bit wet (oil), mostly towards the back. Doesn't concern me too much because it's not even leaking enough to drip, but I'm worried that the read main seal might be going out. Is that a 'drop the transmission' job in these trucks?
Passenger's-side is leaking a bit down by the pan too.
This is what the underside of the pan looks like. Pretty wet towards the back. Also wondering if that 2nd drain hole is supposed to have a plug in it.
Looks like I definitely need to take care take care of this sooner than later. The underside of it is oily and drips a little bit of FUEL!?!
