new to me 73 FJ40
« on: Jan 04, 2018, 04:56:24 PM »
So i pulled the trigger last night on a deal i felt i could not pass up on a 73 FJ40:




some specs:
73 fj40 with hard top, bikini and soft doors included.
freshly rebuilt TBI 350 already wired
freshly rebuilt SM465
NP205
Dana 44 front, shortened with chromoly shafts
dana 60 semifloat rear, shorteded with Dutchman shafts
uninstalled 4.88's front and rear and rear detroit
brand new( but old) 35" KM1's
pile of associated parts from years of the PO collecting.

all in all i have about 3500 in it with trades and cash.

I was previously building this:
http://board.marlincrawler.com/index.php?topic=99755.0

now to figure out what i am going to keep from the T100 build for the FJ and what is for sale because the wife will not let me build both or do i really have the time to.

got a little done on her lately.

in the garage

and the pile o parts

about 92" wheel base

probably about 64-1/2" wide with the axles that came in it.

bolted up my 37's still about 12" top of tire to top of fender. need to drop her some





pulled the dana and threw in my fj80 widened axle and swapped the springs around to gain about 4" to wheel base. 75" outside of tire to outaside of tire with the old axle and 35's not 84" with the fj80 and my 37's and rims.


pulled off the giant rear bumper. anyone need a rear winch bumper?

trying to get the motor stabbed in with he trans next to show conflicts with the 3 link as i am fabbing.
stay tuned.

thanks man. i know the landcruiser stuff is traditionally more of a old guy restoration project than avid wheeler but i have always loved the classic looks and simplicity of these things.

I figure if i build it and absolutely hate it i bet i can still sell it and build a t100. the t100 deals come by more often than the deal i got on the fj40.

on another note i got the motor and trans stabbed in this weekend:


not a big milestone but i really want to get the fenders and grill on also so i know what i need to avoid when building the front 3 link, or i should say what i need to figure out how to move....lol

badass man! ill for sure watch this one. so are you selling the t100?
are you using the toy axles opposed to the danas it came with? ( i hope so for the cool factor)

Yeah unfortunately this project puts the T100 on the chopping block. Good side is I have the parts from the T100 to use on this build or sell off for the right parts.  I am definitely using th Toyota axles over the Dana axles because they are wider and I have been building them for way too long to not use them. I will also be using the 3 link kit and coil overs on this.

I now just need to sell enough parts I am not using like the Dana axles, dual ultimate cases and v6 adapter to help pay for parts to finish the fj40. I am really hoping to get enough funds to throw a atlas behind the sm465 instead of the no205 I have for some crawl gearing.

not a whole lot of progress but I did start upping the front suspension for the 3 link:



but now I have to pull the motor to swap out the transmission because this fell in my lap:


NV4500/atlas 3.8:1, old but never been run. got too good of a deal to pass up. just need to buy fluids for it and swap the yokes for Toyota.

I was going to leave the 4.10's in the axles with the sm465 to make the hwy bearable but now I have OD I can use the 5.29 gear sets already in my tool box and move some of the stress off my driveshafts and pinion flange. I am still planning on using Toyota driveshafts and u joints as I know them and i think they are plenty strong


I have not looked super close but I am assuming at this point my drivetrain weak link is going to be u joint or pinion flange splines. I guess only time will tell.

not a whole lot done last night but I did get the yokes swapped out for toy flanges. turns out this atlas was built in 2002 so it was still a 26 spline front output and 32 spline rear. luckily  WFO down the road had a dana 44 to toy flange that fit the bill perfectly and a 32 spline toy flange for the rear.



also wire wheeled the nv4500 to give it a little paint to keep it from rusting any further.





hopefully this weekend I can pull the motor and get this bolted up and stabbed in. need to rebuild a new cross member now also.

so not as fast getting them swapped as I hoped but that is life.

pulled the motor and trans last night but first had to build a little jack extension to put under the transmission because I was tired of the old stacking of wood block sketchiness.

I used a short piece of axle shaft and a scrap of 1/4" plate to fit on the jack and a tube and angle iron slip on attachment to get the extra height. this seemed a lot more stable than the 4x4's I used to stack on the floor jack to get extra height.




I did get the motor out so now to bolt up the new trans and transfer case and fab a cross member to hold it in place and then get to the links.

engine in the fj40, take 2. This time with the NV4500/ Atlas bolted up.





still need to figure out the right height and build the cross member but I can tell you my engine hoist is glad that is over....

also looks like I only  have about 21" for the rear drive shaft with where the axle is now. I am so used to Toyota minitruck stuff where you have miles of rear drive shaft so this makes me really nervous.

I think with the rear leafs I have now I could probably push the axle back another 2-3" before I have to get into mounting the shackles off the back of the frame. do you guys out there in keyboard cowboy land think 24" long for a rear CV shaft? I need to figure angles based on final ride height because this thing is getting lowered a bunch, but 24" sounds short to me.

not a bunch to report but I finally received my knuckles and FROR keyed histeer arms back and I am pumped!!!! these things are BEEF!



I also purchased some ARP studs for the hi steer arms and the FROR Tacoma brake adapter kit so I can put first gen tundra front brakes on this:

I tried out this "Steel-It" paint given to me by one of our vendors. It is supposed to be super tough and durable and you can weld over the top of it they say. we will see how it works on these knuckles:




in this last picture you can see the machined part on the knuckle so the hi steer arm slides down over the top of the knuckle by roughly 1/4". should help keep some of the strain off of the studs.

I installed the ARP's and the stock bottom studs and then bolted the knuckles on with a temp tie rod to get ready to mock this thing up under the truck.



I think I grossly miss estimated the caster angle I tacked the knuckles on at  because the hi steer arms seem turned up really far but hopefully I can get it under the truck where I think ride height will be and turn them to be right and then start getting the link mounts in place.

so a little more done over the weekend.

got the axle rolled under the truck and started planning location. I broke the tacks and rotated the knuckles to 7 degrees caster with the pinion pointed to the t case so it should be closer to actual now. just trying to figure out how far forward and how high to place bump right now.



 where I have it in the pictures is about 1" from the tie rod hitting the frame, and the axle is about 4-1/2" forward from stock. If I move it back about 2" I can get the bump higher or I might have to notch the frame.  I really want to keep 6" uptravel from ride height and keep it as low as possible for CG reasons.
then I threw on the tires and fenders for some reference and motivation.


she is definitely wide! and I am definitely going to need to do some custom fenders but I am thinking moving the axle back 2" and notching the frame is where I will probably go next, just need to make sure firewall clearance is good for a 40 for possible future growth.

once i get the axle location figured out i plan on building the links backwards of most. i figure i will tack them in place where they fit well then throw those numbers in the calculator and then start massaging from there. i figured there was no reason to come up with link lengths and position in the calculator just to find out they wont work under the truck.
