@jonheld Would appreciate your feedback here given your in depth understanding of the FJ80 vs FJZ80 differences. I have a 91 3FE FJ80 that I am about ready to have Red Head rebuild and do the 105 sector shaft upgrade. I need to order then ship Red Head the OEM parts and trying to make sure 1) I have have the complete list of part#s needed for the rebuild and 2) ensure the 105 sector shaft upgrade is indeed doable for the FJ80 steering box (and not just an FJZ80 only steering box upgrade). I've scoured through the various posts on this topic and believe it's good to go, but just dotting i's and crossing t's to make sure before I go down this path.
Right on Beno, thanks! Any comments you can make about the completeness of my parts list? From what I gathered going through the various posts on Mud this looks like it's the entire list.
For a pitman arm and sector shaft upgrade and box reseal, you've got the parts correct.
So the rebuild on the ps gearbox as far as Red Head concerned was an A+ experience—top notch folks to work with, no question about it. The part that made it difficult was the shop that pulled out the gearbox didn’t insure it when sending via USPS to Red Head even though I asked them to insure it and it low and behold it ended up getting lost in the mail. They did do the right thing though and covered the cost of a new ps gearbox core which thankfully Red Head had in their core inventory. The part list above is the complete list to do it. Some people would just assume reuse some of the bolts and hardware, but I wanted to have clean and new OEM yellow zinc hardware installed. So the sector 105 shaft upgrade on the ps gearbox rebuild in and of itself was a success. Now the only issue is I still have is the pesky ps gearbox whine which is still present after the shop “rebuilt” the ps pump it still whined, then put in a “rebuilt” one from Maval and it still whines.
Having spent so much money and time the inability to fix the ps pump whine has been a huge disappointment. To add insult to injury, Mr T discontinued the 91-92 FJ80 ps pump, but still has brand new OEM ones available for the FJ60, FJ62, FJZ80. If I didn’t love the Land Cruiser as much as I did and the adventures it has provided and will continue to provide my family to enjoy together I’d probably be close to throwing in the towel on it. Despite my LC project being over budget and having taken way longer than first imagined, there’s no way I’m getting rid of it! Sorry that was part answer to your question and part pent up frustration and venting needed about my LC Project.
Now how to convince CARB and the powers that be in California that an LS3 6.2 E-Rod swap is actually way better for the environment than the alternative of forcing me to stick with the venerable 3FE.
But that’s a topic for a different day and a different thread.
Here’s the part list. I don’t remember the exact quantity off the top of my head for the # of nuts and bolts. Brand new gear boxes for 91-97 are available from Toyota, but they’re very expensive. In hindsight, would have Red Head rebuild again over purchasing a new ps gearbox.
Redhead did mine last spring. They don’t want the oem seal kit as they use their own “proprietary” seals on all rebuilds. I sent them only the gear box, 105 sector shaft, and the adjustment screw.
