Sequoia Family Crawler

Gee, thanks for rubbing it in. Progress has been slow with end of school year commitments but I did get a couple things done as long as a bunch of shopping.

In my quest for up travel the oil pan was for sure in the way. I bought a ring on eBay and built a rear sump low profile pan. Still have to build a pickup and windage tray but picked up a ton of clearance. TIG welded the whole thing to minimize leaks and coated in a couple heavy coats of enamel inside and out. Deleted the dip stick and went with a threaded bolt on the side to set oil level.

I also got the front axle truss complete. I could not find a truss with low enough profile to miss the oil pan and was also sealed from trapping mud and dirt inside. I welded 1/4" cold rolled steel to the center chuck using ni55 mig wire, preheated to 350 and cooled in a blanket overnight. The rest is 1/4" cold rolled welded to the tubes with an internal rib, designed as a bump strike on the last 3" or so. Truss is rolled 3deg back to pitch the pinion up and set the caster at 6deg.

Transfercase plans changed a bit with ordering a doubler plate that will use the front half of an NP231 and bolt an entire NP242 behind it. This gives me 4wd with an open center diff for snowy street driving and double low range to make up for not gearing the axles for now. It also helps balance the lengths of the driveshafts to closer match the link lengths.
 
Made damn sure that paint won’t peel off. That would suck ass to have to peel off and plug the pickup.

Looks bad ass though as usual, Brian!
 
How flat were you able to get it?
Dunno, 8in or so after moving the sump? It's now 1.75 off the motor block. The motor itself is moved up about 2in at the axle as well for all the up travel clearance.

@85Yota I still have your SC400 oil pan at my house you brain damaged oaf. It did save me some money by ruling out buying one off eBay to use.
 
Haha I didn't even remember I let you borrow it. Thanks for reminding me. I got some many parts for so many projects I lose track of where everything is.
 
Replacement front frame section is in place. Should make for lots of room for up travel and clearance for steering and panhard bar. Will finish plating in once link and coilover clearances are verified.

This is definitely going slower than I anticipated but I guess they all do
 
Looks awesome. No issues with motor mount location with the frame being that much narrower than factory?
 
Progress continues with motor mounts. Built up on a spare motor using a polyurethane bushing and the Toyota style bolted plate to be able to slide the motor forward and out. Designed in CAD to hug the stock manifolds and keep ample room underneath for the upper link. All cut by hand on a bandsaw, coated with Seymour butts, and got the motor mounted solid.

I'd throw headers on it now and be done with it. The stock manifolds are garbo.

The nut is tacked because Toyota did it that way and I'm getting sick of holding two wrenches at a time when it's not really needed. They'll be easy enough to replace if they strip when I form a new hobby of pulling motors weekly. The picture is a bit deceiving, there is quite a bit of clearance and I do wish it was tighter but wanted to maintain a bit of an air gap between the poly bushing and the hot manifold. I could probably remove the manifold as it is now.

I have ebay headers sitting on the shelf and was probably going to end up mocking them up. They present some steering shaft challenges but nothing like a little more scope creep.
 
Ah, the bolt should always be pointed down when possible so that if it loosens up gravity won't help it back out. Especially important near high vibration areas it will buy you a bit of time to tighten it back up if it is found before it falls out.
