FJ140 Build

Nice cheat code

 

[Crash]

Thought I would share a shot that @CardinalFJ60 took during the pre-run of the 140 flexed out on 7 Mile rim trail

80s chassis and suspension is the cheat code. A 60 suspension would have the driver rear tire hanging 2’ above the crack bottom.

Started to repair the damage from rust and a rock from cruise moab this year. I was able to cut a patch panel from a damaged 80 series front fender. After some custom forming and welding it fit in pretty decent. Now just need to add a little filler and repair the raptor coating.

Also pulled the trigger today on a new 5 speed to reduce the RPM's on the road trips.

Damn Mike...impressive skillz. Let me know if you decide to take on some side jobs. I've got some minor sheet metal repairs needed on my 78 FJ40.

My local toyota dealer was running a 20% off sale so I pulled the trigger on a new H55f. Only took 2 days for it to arrive and I picked it up this morning. I have been reading different threads about this conversion and there is some disagreement about needing the 5th gear oiler cup. Has anyone had experience with this? I think this is the last upgrade for this rig.

Wow, that's a thing of beauty!!

Yeah you need the oiler cup, the t case should have provisions for it if you have the right one. Also, you may want to dry shift it and make sure it goes into all the gears and that the output shaft spins accordingly. I've had two separate ones where the 3rd gear syncro was jammed onto the cone preventing the tranny from spinning correctly. Had to pop the syncro loose with a flathead screwdriver...

Not sure on the oiler cup. I have seen Mud threads where some folks state its critical, others have 100k miles on the transmissions with no issues or signs of wear.

What is critical is the plug that goes in the hole below the transmission output shaft. The PO did not add that when mine was installed. I learned this when I first went to change the fluid and had both drain plugs off. When filling the transmission fluid ran right out of the transfercase drain. Without the plug the transfercase will always be high on fluid, and the transmission will always be low. I am lucky this did not cause any long term damage to mine. It was definitely a fun discovery. I am sure you read that in the conversion threads, but better safe than sorry.

You are going to be stoked with the 5 speed. Lower 1st and OD 5th are amazing upgrades for daily drivability.

Still waiting on a few parts to put everything back together. After reading a few threads on mud I decided to pull the 5th gear housing so I could do a proper seal on it when I get the bolts and oiler from Kurt. This will get some FIPG and the paper gasket when it all goes back together. I also dropped the factory drive shafts off yesterday to have them rebuilt for the new developed length of the drivetrain.

 

[Capriblue45]

The oiler and bolts showed up yesterday so I got the assembly all put together and ready to go back in. Still waiting on the clutch kit and rebuilt driveshafts to be able to bolt it back in.

Did your T Case have the hole Kevin was talking about or no? I've had both. Just double checking you addressed it if needed. It would have probably been obvious to you as it looks like/probably is another bolt hole. Also it dry shifts OK? like did you double check it spins the output in each gear?

 

[Capriblue45]

I'm still waiting on the 5 speed shift lever but I was able to row through all the gears with the 4 speed shifter installed. I had changed out the t case to a later model 38mm idler shaft when I did the 4:1 low range gears and plugged the hole at that time.

Finally got all the parts and completed the 5 speed install on the 140. It has a lower first gear that will take some getting use to as it requires a fairly quick shift into 2nd, but I do like the reduced RPM when running 70. I had to lengthen the rod that runs to the high/low shift selector by 1" due to the 3-1/2" case for fifth gear, and do some creative bending on the transfer shift lever to get it up in the factory hole but nothing that shows. Mine is an mid year 1984 so no blank case like the 85-1/2 and up had. I also needed to shorten the rear drive shaft and have the front retubed for an extra 3-1/2" of length. All in this mod cost about $4,200 with me doing everything but the drive shaft modifications as I wanted them balanced to eliminate vibrations. I think it will be worth the effort for the longer drives I plan on doing with the truck.

Now I just need to get the AC working to make it a more pleasant road trip rig.
