Diesel GOAT: The one I wish Toyota would have built

[helipilot77]

Welcome to page  2

ordered this tonight. It should solve the main problem with the thermostat.

I think I am going to go with this for a radiator fan controller if I go electric: http://www.dccontrol.com/constant_temperature_controllers.htm
It gradually brings power into the fan as temperatures rise rather than jolting it on after temps are already high. keeps the electrical system happier.

What is it? An inline thermostat?

[helipilot77]

Yeah. It holds a standard Chevy thermostat. So it has the added benefit of providing me with an easy replacement thermostat instead of needing to order one from Toyota Japan.

That is perfect.

Radiator arrived yesterday. It appears to be a quality piece. All the welds look good. Looking in the top it looks like there is plenty of brazing around all of the core tubes. Now to toss it in and see how it goes.

[helipilot77]

Well got the fan shroud on. I wish the Chinese manufacturers could test fit one of their products before selling them by the truckload. The nut-serts for the shroud were in the wrong holes so I had to use regular nuts to mount the shroud.


Here is the old pig. It must have weighed 15 pounds empty. You can see many of the fins are clogged with mud. 


Got the new unit in and all hooked up. Filled with coolant and ran it up to temperature with the cap off. No leaks and holy  this thing keeps the temp cool. Aluminum is such a better material for a radiator.


So I got it all installed and tried to close the hood, but it just wouldn't latch. The hood reinforcement was hitting on the radiator cap. So I fixed it.

[SqWADoosh]

I swear I'm the only one who has ever gotten a aluminum aftermarket rad that didn't require hood clearance. Looks good dude. You assessed whether or not the head got cracked yet?

[helipilot77]

Not yet. I will have to wait till the head comes of till I am sure. It needs to have the head gasket replaced anyways.

Dude I wish I had known you were working on it today. I was driveing home through Seattle today at 2

It's okay. I didn't get home till 3:00.

[redneckcustoms13]

I didn't trim my hood. But u did drop the rad about 3 " lol

Today after work I pulled the radiator fan out. And unbolted the fan from the viscous clutch. These things are notorious for running dry.


Once I split the two halves I saw that mine had hardly any oil in it. I was suspicious of this and had purchased some RC differential silicon oil in 10,000 Wtg.


Now when I am driving I can hear the fan whir up to speed along with the engine. I drove it on the freeway today in heavy stop and go traffic with no problems. These cooling improvements are doing some good.
In case you're wondering Toyota originally installed 7,500 Wtg. 50 ML is all it needs.

Ofna racing.. That brings back some good memories..

[redneckcustoms13]

Used to have a team ofna fuel bottle, glow plug ignitor, and a bunch of other stuff. Impressive how you changed the oil on the fan clutch.

Interesting. I had no idea that our fan's had oil in them nor that it needed to be changed. I guess I should do this as well seeing as I'm pretty sure they used my 22RE fan on my swap so that means it is 30 years old... 

[helipilot77]

I forgot to mention that 4crawler has a nice write-up on changing the oil in the viscous cutch, if anyone is interested.

You can get a little bottle of the oil from a toyota parts dept and it's super easy to do.  Worth getting a new o-ring in there while it's apart, too

I wanted to try a stiffer weight oil to encourage a little better Cooling.

[redneckcustoms13]

A bolt through fan clutch handles that according to a guy that used to ride with us. His tired 22r was even more weak trying to turn the fan at all times

Started the work on my steering box today.
For a little back story. Two years ago right before I went to MCR 12, I ordered a rebuilt steering box from marlin. I got it, installed it, and it had more slop than the old one. Also the power valve didn't work. When I called to see what they could do to fix the problem I was told it just needed to be operated more to bleed the bubbles out of the fluid. So I drove it for a couple months making sure to turn the wheel from lock to lock often when parking. The situation didn't improve. I called them again right before leaving for MCR to report that there was no improvement. I was then told that I needed to replace my pump. My pump had been working perfectly before I had changed the box. And that would not solve the problem of the massive amount of steering slop. I didn't enjoy not having power steering on the rubicon or the the sloppy steering driving from Seattle to Tahoe and back.
I have since called, messaged, and emailed different members of the sales staff with no reply. 
So I am going to rebuild my old box myself. While I am at it I am going to tap it for power assist...You never know. 
I know there are lots of threads on taping the box, so I won't cover that much.

Started by pulling the main shaft out.

Then pulled the power valve out.

Then I tore down the power valve.

I love these thrust washers.

This is the thrust adjustment nut. It was a bit challenging to get off without the SST, but I got it. Normally I would have made a custom tool for the job but my welder is over at zippo's. I used a Alan wrench in the spanner hole, a pair of vise grips to bridge between the steering shaft and the Allen wrench and a cold chisel to break the locking nut free of its stake.

I can't believe the cage on this thrust bearing is plastic!

Adjusting the thrust on the thrust screw to 0.0012

Here is the power valve all broke down.

If you follow the Factory service manual, it will tell you to beat the  upper main shaft bearing out with a brass drift. If you do this it ruins it. The better way is to press the lower main shaft bearing up until it contacts the upper main shaft bearing and then press them both out together. This is what I did after having already destroyed my upper bearing. So now I need to replace a $45 needle bearing.
Next will be drilling and taping for hydraulic fittings.

Stoked to see you are addressing this issue yourself after Marlin dropped the ball. It really is upsetting that you were ignored on this after spending your hard earned money on a box through them. I couldn't believe how bad it was when I drove your truck last Sunday. It was very scary, and it is crazy that you keep your truck straight down the road with it in that condition. Really hoping that BigMike comes through with some kind of compensation for this.

Id get the genuine seal kit.. I have the part numbers if you want them
In fact i have a seal kit that was going in a RHD box thats now no use to anyone...

I plan to. I was going to stop by the dealership yesterday, but got sidetracked. Is it 04445-35080? Best deal I could find is $103.85

I've heard there are 2 IFS steering boxes from 86-95 with the later version geared differently so there is less rotation of the steering wheel to turn. Do you know this to be true? If so,  I must have the earlier version as it takes a lot more rotation of the wheel to turn than it did with my 85 push/pull box.

There are two versions, although im convinced there is no gearing difference, the later version has a valve operated by the piston whereas the earlier version does not.

[OVRAROK]

Early version 86-88 p/u and 86-89 4runner, later version 89-95 p/u and 90-95 4runner, the later box is 1 " longer at input shaft, and also Has different, faster internal gear ratio, requiring slightly less turns

Of course nothing here was ifs till '96 and most of the surf imports were 89 on... We have no early version

[helipilot77]

So I went by the dealership with my part numbers. The bearing was only $24. But unfourtunately the seal kit is no longer available from Toyota. So I went next door to NAPA and asked if they could get me the seal kit. They had to order it of course but it was only $43!

[Speed]

See there-Just cuz ya can't get it doesn't mean ya can't get it!
   Speed

[helipilot77]

So hopefully my bearing arrives today.  In the mean time I started installing my PLX that I traded Zippo for some shocks.

[BigBluePile]

Very cool build, nicely done!
