Are rear gate handle available anywhere or is that a used item?

@DoubleNickels had some options at Shapeways and made some springs too.
I would reach out to him and have him point you in the right direction.

I'm working through the details of a 1uzfe retrofit so I understand your pain. There are alot of details to work through.

1. It looks like your oil pan sump is a mid sump but you still need to check the clearance with full articulation of the front axle. I had a front sump setup on my 1UZ it requiring retrofitting with a mid sump upper/lower oil pan.
2. Lextreme in the USA is a great resource rewiring and immobilizer bypass. The guy from NZ also seems to be a master at the UZs
3. Plan on a hydraulic throwout bearing for the clutch. The exhaust manifolds seems to make it impossible to use a traditional clutch fork system.
4. Nice job eliminating the hydraulic fan and re-routing the serpentine belt. I'm going the route of retrofitting with an idler pulley and keeping the belt length the same as the stock engine.

Keep up the good work!!!!

@xtremeVA Some good advice in there - thanks!
My sump is a full rear from an SC400, that, plus the 4" of lift I am targeting I should be ok. Plus, my j70 series springs are offset forward an inch and I have the ruff stuff lower u-bolt plates that give 3 mounting options - I had planned on using the front one to recenter the axles to the frame, but in theory could push forward 2 inches if needed.
Yeah, I sent the wiring harness to Kelvin last month - took him 2 seconds to diagnose it needed an immo, he will fit and send back. Also been all over lextreme along the way - it was usually kelvin who ansered my questions there.... I am still pissed that after carefully seeking and engine without one i ended up with one. Ah well, along the way of troubleshooting I replaced damn near every sensor and learned a ton about the engine.
The Hydraulic throwout is really good advice, wish I had it before I got the transmission mounted, but better now than later. I have never had a transmission just slide in like in the videos, this one took several hours over multiple days (and I have a transmission jack). I will research, but let me know if you have a part and source for one that will bolt up.
Pulling the h fan was super easy, a few bolts, a piece of string and a tape measure and I got a new belt one from rockauto clean and simple

@tucker74 @J Mack thanks for the advice on the handle, mine is pooched , no way to save or use it, it cracked half way through where the pin goes through and is some kind of plastic I cant repair... will reach out to @DoubleNickels or steal one from the other pig when we move up north (hate to start stealing parts from a runner though).

Found a couple of options:

Although they do go out from time to time, we offer OEM quality replacement hydraulic release bearings for our UZ adapter kits using a single disc clutch setup. We've tested a variety of different ones over the years, and found this one to be the most reliable, especially at this price point...

I used one of these on mine, I had to machine a few parts but it has worked well.

Thanks @J Mack, do you have any pictures of what you did? Did you buy a more complete kit and work with the bits or just buy the bearing and fab from there. I assume the fab involved building a bracket to hold the bearing in place and connect it to the transmission(?) Appreciate the advice, thanks

 

[J Mack]

I bought a universal bearing and had to machine the trans snout down a few 0.001” to get it to fit, other than that I remember it being straight forward. I know there is some photos in my build thread somewhere.

Regarding the cooling fan idler bracket/pulley, I don't think you really need one since you already figured out to completely eliminate the pulley. For reference, aftermarket fan idler pulley brackets are available. I even ran across an Aisin branded one...but it is a bit more expensive. I put a link below as an example of each piece for reference.

Thanks, but I was trying to understand the hydraulic throwout bearing challenge you pointed out. Above are a few options. I've never installed one, but it looks like you replace one of the transmission bolts with a stud that the tob slides on and then shim to correct depth if my morning of not focusing on my work is correct.

J Mac seems to have used a thicker one that required some trimming to fit if am understanding correctly. I'd rather add shims since I don't have a lathe.

I am wondering more about which one would have the correct placement of the stud to my trans - or does one tap a new hole?

Drill and tap a hole if one of your existing holes don't line up.
My NV4500 snout from memory was 1.400" and I needed to machine it to 1.370″ diameter, I'm guessing yours is not that big.

That, @J Mack is, as usual, very helpful,

(I did dig through the Target Carrier build, but didn't see it, or missed it within the 118 pages)

thanks!

Verifying something. The instructions for the tob seem contradictory (and I haven't even had any beer yet). Line 4 says the distance to the tob and fingers should be the same. Line 6 says if done right they should be .060 apart.. I am thinking a slight gap maybe gets a slightly lower pedal, but maybe extends the life of the tob..? Right now I have 0.050 - good to go?

Funny story.... My Grandfather and Dad used to brew beer in the basement during prohibition and now my Dad is 99 with dementia and can still shout out the ingredients for their special brew. We come from a long line of brewers!
