Yes! Yes indeed!

That's awesome!
Thank you!

Mine is a 1980. Do you think it still applies to my truck, since these say 1968-74 ans 1976?

 

[Joe45]

The bracket I found while driving (fell off?) is almost identical to the one in your photo, except the bends are in the opposite direction.
The slot/sliding hole on mine has been bent, so I need to straighten it out somehow so the adjustment bolt can slide back and forth on it. Can't find my blowtorch right now, so I may walk over to the auto parts store and see if they have a similar after market bracket.

Have a search around.. I think everything is here somewhere

Maybe can use a long pipe to bend it back. Need somewhere to bolt it down - maybe the front chassis rail?

Looking again at your photos, it looks like your alternator has been rolled right down away from the motor to make room for the ac..
The ac was then fitted with two adjusters to stabilise it?
Can't you just roll the alternator back up to where it belongs and use the existing adjuster with less washers?

Yes, I agree. I've been thinking about that. This also seems to be why changing the oil filter was such a nightmare: the alternator was in the way.
The issue with the AC compressor now seems to be keeping tension on the belt, because of the angle, but I can probably use the brackets that are there as a base for the AC compressor.

I began removing the bolt where the alternator bracket should be but right now holds one of the crappy brackets. Coolant began leaking out-no surprise as this is the housing for the water pump or thermostat I think. I tightened it back up and stopped the leak.

I am considering an unused, lower tapped hole on the front of the block for the alternator bracket, this way the AC bracket can be independent of the rest.

A reply from a vendor; Rather discouraging...

Parts for this vehicle are not commonly available in the USA for this vehicle as it was never imported by Toyota when new. We do not have a replacement for the paper element oil filter. We do sell the paper elements as part number 026-01G for $17.35 ea.

Crank pulley is part number 034-15CC-U. We may have a used one for $491.00
Water pump pulley is part number 054-013CC-U. We may have used for $179.00
We do not have the alternator pulley available.

We do not know of a wiring harness for this model.

We do not have a replacement speedo head available.

We do not have a van belt available for this model.

Fairly standard experience from mainstream vendors here.
Half of my parts have come from France, the other half from Germany.
You can get anything in Australia in abundance.
Seems like you have a lot more wreckers in USA than UK. Seek out the specialists.

Yeah makes sense. Terrain Tamer seems to have a lot of really good stuff. I may do a bulk order when ready to start the rebuild.

Question:

Would welding on something attached to this vehicle possibly do any damage? There's no computer, so I don't see how-but just in case.
I did that on my old CJ and no issues, but not familiar with LC diesels. Figure they should be even more bullet proof but you never know.

What I am doing is tac-welding my alternator bracket while attached. I have one part bolted to the water pump/thermostat bolt area and the other to the alternator. This allows me to align them nicely. I plan on tack welding once on each side, removing, finishing the weld, then (after painting) installing.

The AC bracket will follow, but the alternator is far more important-obviously.

Back in the late 80's I drove a CJ7 from the SF Bay area Peninsula to Baltimore, Md. as part of a driveaway service, were you drive someone's vehicle as your transportation and pay for the gas. I wasn't familiar with the vehicle, but became very familiar after it wouldn't start in Colorado, it had something to do with the ignition switch. Made it cross country in 4 days. Do it!!

 

[45Dougal]

Should be fine. Just don't set fire to it. Outdoors, and away from the battery and fuel system

LOL!
Yeah, I'll disconnect the negative battery cable just in case, and it's on the opposite side, so should be OK then.

Thanks!

Thanks Terra! I already did the trip and it was well worth it!
Funny enough, it's now that I am getting acquainted with the HJ! Gonna get more acquainted once I start the tear down/resto-mod!

Yikes what a couple of days!

• Bought a spool of fluxcore wire for my welder this last weekend.
• Monday I spent the day figuring out what to do.
• Removed one of the hack brackets from the HJ, cut it in half, cut the one I found in half, and combined them to make a new one.
• Tuesday I figured out I didn't have the right wire nozzle. No vehicle so asked my wife to pick it up on way home.
• Today I go to weld. Welder sputtering and not welding.
• While adjusting spool, it comes loose and lost the whole spool.
• Walked to hardware store in 100 degrees and got new spool-and a Mississippi Mud ice-cream sandwich.
• Walked back in a little cooler weather with clouds moving in, and cramming the ice cream in my face.
• Removed useless gas shield nozzle from welder (flux-wire only welder) and plugged it into the outlet right under the relay box.
• BAM! Welder worked great.
• Welded bracket.
• Waited for bracket to cool off, painted, then waited for it to dry.
• Went to install it and realized I had welded it the wrong way!!!!
• Cleaned off the paint.
• Chopped it and flipped it and re-welded it.
• Waited for it to dry.
• Repainted it and slapped it on.
• Now it's on!

YAAAAAAYYYYYY!!!!

I'm getting about two inches of travel for the alternator from touching the engine to as far out as possible. Should be enough to tension the belt methinks...

Now I have to figure out how to put the AC compressor back on. Not sure I can.

 

[Joe45]

So it seems the only way to get that compressor on is to make a bracket that bolts onto two or three of the exhaust manifold bolts, then extend a plate over the alternator.
Maybe have a hinge with a bolt to pivot the compressor to help with belt tightening?

Worrying this will put stress on the exhaust manifold though, as well as heat radiated through the bracket and into the compressor. The stress part (along with vibration) is particularly an issue if I can't create a third point of contact for the compressor plate: so it's not just hanging over with no support for that heavy compressor.

Anyone agree? Disagree?

Also, this will obstruct the alternator, but as long as I make the compressor easy to remove, shouldn't be bad.

Weighing the options as its dinner time and I will likely pick this up tomorrow.

Opinions welcome!

 

[Joe45]

I disconnected the negative battery cable, touched something on the alternator with the ratchet, and got a lovely spark!

Anywaaaayyyyyyyy...

Not sure if this makes sense, but what I'm thinking about the AC bracket.

 

[45Dougal]

Good job getting the alternator bracket welded back together. Looks a lot more stable than before.

I wouldn't go anywhere near those exhaust bolts myself. They're the most likely thing to snap in the head and that's the last thing you need.

How about below the alternator, sharing the same pivot, plus a new 3rd point underneath somewhere?

Alternatively a double pulley on the water pump and put the ac up top above the thermostat - several bolts there you could pick up on - is there room for either?

Otherwise how about using a length of say 4inch channel to carry both alternator and ac together, and then fit them as a single unit using the existing points

Thanks!
One of the hacked AC brackets was attached to the manifold bolt. Took that off.

Up top the pump will be too high for the hood. The radiator hose gets in the way if I move it to the left. To the right are the batteries.
Below could be an idea, but then oil changes would be a pain again because the filter housing is blocked.
The double mount is, I think, the best idea (thanks)
Also, maybe moving the batteries around and mounting on the left side of the engine could be a possibility.

I'll look at the possibilities today.
