What's the procedure for checking for a bent housing ?You may want to check your axle housing to make sure it's not bent while it's apart. A bent housing will cause premature axle seal leak.
Alignment bar, you’d use the saddles in the carrier to line it up usually, not sure how you’d do that without a removable cover. Maybe just try and slide in from the short side. You’d need some sort of puck clamped in the carrier to match the diameter of the bar. You could measure distance from bar to housing on top, bottom, front and rear side where it passes through the seal (seal removed) on the housingWhat's the procedure for checking for a bent housing ?
ThisI’d bet your axle is a little bent or warped

If there was no index to the third member (machined pucks that clamp in the carrier bearing bore, with a tight tolerance ID to index the alignment bar) that tube through your housing won't really help you with much at all. It won't keep anything straight while welding, and it won't let you know if your housing is bent.View attachment 2721676
something Like this ? I used to make sure my housing did not warp when I was welding the truss. there a hollow third and a piece of chromoly pipe.
Ha ha of course there is, The hole set was made by a engineer friend wheeling buddy of mine just for welding on axle housings. And no that pipe won't stop warping that's what the big a** I-beam is for.If there was no index to the third member (machined pucks that clamp in the carrier bearing bore, with a tight tolerance ID to index the alignment bar) that tube through your housing won't really help you with much at all.

SLICK ROCK
With the truck back together, I met up with @Road Apple and hit up Slick Rock for a quick day trip. Ron's has a super nice LX with the first 80 bumpers built by the guys at Dissent Offroad - incredible work on these bumpers. I don't know if I could go crawling with a truck as nice as this. Hey Ron, you need a build thread!
The last time I ran Slick Rock was 2019 and the trail has definitely changed a lot. It's almost unrecognizable from the first time we ran it in 2012. Lots of traffic has really chewed this trail up, but that makes it challenging! I just hope this one stays open for years to come because it's one of my local favorites.
Video of me coming down the 'Gauntlet' which is part of the re-route at the north end of the trail. Steep downhill (or uphill) boulder field. Because it's mostly loose dirt, it's gotten really gnarly with deep holes compared to last time I ran it.
And climbing the Staircase at the south end. Went too far driver side and fell into a huge hole that was too deep to climb out of. This is why I'm glad I don't have a full bumper with swingouts. It would have wedged me here pretty good.
It's looks like a really fun trail !! And I agree Ron you need a build thread !!
Those tube doors are sweet and on my list. Are you running electric fans? Thought I could be that distinct sound.
I don't see an answer to your question on is that new HG ok with it not a perfect circle around each piston..is it? I'm about to start a motor rebuild with gaskets and seals and timing chain on their way so I'm "studying" as much as I can before the journey begins. Also, after scraping off the old head gasket, how did you clean out the block with the tiny bit that will get into it?HEAD REASSEMBLY
It's finally time to start the reassembly process! Hopefully it goes a bit quicker this time around. I won't be taking pictures of everything, maybe just a few important items. At this point I'm waiting on a new torque wrench I ordered so I can finish bolting down the head and continuing on with the rest of the parts.
After cleaning the block surface and pistons I set out to clean the head bolt holes. The head bolts are threaded in the M11x1.25 unicorn thread which makes it almost impossible to fine a thread tap at a local store. I purchased it from here: http://www.mscdirect.com/product/04993051
Don't skip this part! My bolt holes were full of crud! Here's an example of what came out of every hole
As mentioned earlier, I chose not to reuse the stock head bolts and because a new set of OEM head bolts would have cost about $180 for a bolt that's basically not reusable, I decided to buy a set of ARP studs for a cheaper price. I went with the Opel V6 kit (item # 209-4702). This comes with 16 studs so you have 2 extra.
The front 2 studs need to be trimmed about 1/4" so they won't interfere with the cam gears. Here's what I trimmed away with a Dremel tool and a cutoff disc. I also slotted the head so I could use a screwdriver to insert/remove. I hope I cut enough. I'll find out when I install the cams!
Wiped the block down with some rubbing alcohol and set the new gasket down. You'll also notice the bit of gray FIPG sealant right behind the timing chain as specified in the FSM.
And here's something that threw me off. The brand new OEM head gasket does not follow the circle shape around the cylinder. My brain can't process why the gasket is "deformed" at the 10 and 2 o'clock positions. This is the same for all cylinders.
This is my first HG job and as a non-engineer, this defies all laws of common sense for me. The Toyota guys obviously know what they're doing but I can't understand why a HG would not seal perfectly around the edge of the cylinder. Wouldn't that just set it up for premature failure? Are all OHC engines setup like this?
And to compare, let's look back at my old HG. Where I thought my old gasket was warped and deformed turns out to look exactly like the new OEM version. Was my gasket even that bad to begin with? Color me confused
They are designed that way.I don't see an answer to your question on is that new HG ok with it not a perfect circle around each piston..is it?
