Builds Grey Gardens FJ62LG-PNEA: An idiots guide to resurrecting a high mileage FJ62

[HemiAlex]

@HemiAlex
What benefits does the 80 series 3FE fan clutch offer over the 62 3FE fan clutch?

It’s a bigger clutch that is designed for a heavier automatic vehicle than what we are using it for.

I find that it stays engaged longer and earlier than anything else I’ve seen. I’ve had people on trails ask me if I had a fixed fan clutch. It’s that loud.

These are all good things. You can really feel the air coming off of this one.

Tightens the steering up and gives some more power assist.

''Tightens the steering up'' Is that because existing steering was worn out, or is this a upgrade when compared new for new?
Which parts were involve in the swap? is this a common thing to do?

Both. Around 200k the boxes start to get loose.

Just a box from a 93-97 80 series. You just transfer the originalpitman arm to the new box.

I would consider it the best, but not most common option to any truck that can accept the 80 series box. So mid 85-87 60 series and 88-90 62 series.

My untested, unmeasured, uncounted observation is that @HemiAlex is correct that around 200k the 60 series boxes become loose and begin to leak. 80 series boxes seem to be constructed better - tighter tolerance, better seals, other ?? - and can absorb more miles before leaking. The box on our 1997 80 series has ca. 320 k and remains leak free. I installed an 80 series box on my FJ60 because the West TX Off Road rebuild was leaking. This 80 series box of unknown mileage has no leaks. Our other 60 will be getting an 80 series box as soon as we get around to installing it, already have the box.

My stock 60 series box was at 320k when I pulled it. It was leaking badly and very loose.

I wanted to rebuild it locally, but the local rebuilder only reseals and paints it. They don’t even adjust anything and it’s $300.

I paid a little bit more and got an 80 series box from rock auto. It was rebuilt, to what degree I don’t know. It dropped in, firmed up the steering and the assist is way better. I also did a new oem power steering pump and an aftermarket hose at the same time. That system will never need to be touched again as long as I own it.

I like how you worded it. It won't need to be touched, but I know you...

 

[HujSGory]

Guess I should keep my eye out for a 80 steering box then! ''just in case''

 

[HemiAlex]

I’ll go outside, all the power steering fluid is on the ground.

Thanks Steve.

Does the stock pitman arm from the 87 fj60 fit the 80 series sector shaft? Gawd that's a nerdy question if I've ever asked one....

Yes to the 80 series sector shaft. If the 80 series box has been rebuilt with a 105 series sector shaft then the answer is no.

What is the reason for going with a 105 sector shaft?

 

[Godwin]

What is the reason for going with a 105 sector shaft?

It's a stronger shaft and mod that 80 series guys do when running large tires because the stock 80 series shafts were becoming twisted. A 60 series pitman arm will not mount to a 105 series sector shaft.

I think I've read in the 80 series forum that new OEM 80 series steering boxes have been upgraded with the 105 shaft, but I could be mistaken. Another clarification needed, will an 80 series pitman arm work with 60 series steering linkage? I think I've read that it will but I don't remember for sure. Are the holes for the relay rod the same between 60 and 80 series pitman arms? Will the curvature and drop of the 80 series pitman arm interfere with 60 series steering linkage or anything else?

 

[HujSGory]

What about the 80 series steering pump? will it fit, lots or 80 series pumps for decent prices but not so much for the 60 unless imported.

No because the steering pump is integral with the 1FZ block, not a separate, bolted-on, belt-driven, component.

Hmm, not the pumps I am looking at... Power Steering Pump For Toyota Land Cruiser 80 HDJ81 4.2L 1HD 1HDFT Updated | eBay - https://www.ebay.co.uk/itm/362902971518 that certainly does not look integral to me.

Or is it driven via internal mechanism?

Godwin is saying the pump is internal on the 1FZ motor the ebay link you supplied is for a 1HDFT motor.

 

[Godwin]

This.

 

[HemiAlex]

I use the oem 2F 60 series pump and it’s great.

If anyone is in Houston and wants to drive my rusty but extremely nice driving 60 I’ll toss the keys to anyone willing.

It looks worse than it drives, but that was the point.

The 62 will be the same level of detail and a good driver, but look stock and pretty.

Grey Gardens made it home. A few things worth noting:

1. The truck lost power/turned off at speed and popped the efi fuse. It was an original fuse. I checked it after realizing there was no power to the fuel pump and replaced the fuse. It was 10 miles into a 45 mile trip and it didn’t do it again. I’m going to check grounds and make sure the efi relay is fine and I’ll throw the spare on now. What do at @4Cruisers and @red66toy think?

2. I need to replace the main fuel hose from the filler to the tank. It lost about 1/8 of a tank on just that alone.

3. The transmission and t case are coming apart. Lots of backlash and gear noise from the t case. At 291,587 miles it’s not surprising. The botched Rodney flush Got a lot of the contaminated fluid out of the trans, but it still needs help. Thankfully A440f shifted and acted right. I’m amazed.

4. The catalytic converters were nuclear hot and really kept the floor pan warm. I need to get those sorted and fix a small exhaust leak.

It was a great drive. I can see how a properly functioning automatic can be great in one of these, but it’s not for me. 5 speed swap incoming.

It’s running far better now that it got some real heat into it. I can’t wait to see what the bypass oil filter caught.
