Builds My 40 Build... 20 years and Counting... Purists beware, this may hurt... :D (1 Viewer)

Getting to the hardest part of the conversion. Lining up all the belts. Here’s where I’m at…

I’m thinking I’ll switch to a double pulley P/S pump. Otherwise the P/S pulley will have less than 45* of belt contact. The air A/C pump might clear the single P/S pulley but it’d be very close.

A couple other pics. Tightened set screws to mark where holes should be. Countersunk holes for set screws.

Added a small plug in the open end of the outer DD shaft.

Bought a steel version of the above.

The local hydraulic shop indicated the brass fittings are not rated for 1500+ psi so I paid a couple bucks more for the steel one.

And the lines from Rock Auto. Gates lines made the beginning of this year.

The local part shops said they’re NLA and speculated that RA must have bought up old stock… apparently not the case.

These lines were the perfect length for a V8 install. They may not be long enough for a straight 6.

With the small O-ring to inverted v adapter, the stock Scout II lines fit without modifications. I should be able to buy a Saginaw P/S pump anywhere, and if it doesn’t use the newer O-ring type fitting, I can remove the adapter and be back in business.

Scout II box is stock, TRE is stock 80-81 mini-truck, and the tie Rod is stock Fj40. Slip joint and U-joints are Flaming River… but several companies make DD joints should they ever need to be replaced.

Gates part numbers:

Low pressure 352870
High pressure 361550

Pump made from parts of three pumps to get the housing, double pulley, and brackets needed. I’ve selected parts from the three pumps to increase pressure. I’m not wanting anything crazy… just somewhat over boosted.

Also measured and bought a belt… it was too long. Took it back. Got two that were in stock. One an inch shorter and the next was 2.5” shorter. The first was too hot, the second too cold, and the third was just right. ACDELCO 15350

Well… apparently I used the wrong pump. It’s patched together for now with a ratchet strap for a tensioner, but it works. The pump howls, but the wheel turns with one finger.

For about $50 bucks I can get a pump with a warranty… so I’m not going to mess with another pump of unknown health. It’s not worth the gamble on a scrap pile pump… even if it works for now, I have no idea how long it’ll work before it fails.

One finger… who’d have thought it possible in an old 40.

 

[bikersmurf]

I picked up a P/S pump for a 3/4 ton 1980 Chevy Pickup truck. I bought the core only and the parts match what I’ve got… or perhaps even slightly higher pressure.

Now that I have all the air out, with the first pump, I’m able to palm steer… no more two handed.

Picked up a rear 2003 TJ seat after checking out its measurements. It is the perfect width to fit between the wheel wells, has quick release levers, back folds flat, seat tumbles forward, and pull a lever to release bench for removal.

It has built in tie downs for two car seats, I’m going to add two seat belts with shoulder belts, and a centre lap belt. In a pinch I’ll be able to fit three kids across the back.

Depending on the size of the kids it could be very tight. I’m considering adding extensions to the seat that are mounted to the top of the fenders on both sides. Once the seat is installed I’ll have better idea if extra cushions would help.

Ford shock towers look like the best way to go with the Scout II steering conversion. Many just modify stock towers, but I’m already running longer shocks after ruining stock length shocks by overextending them.

They are marginally taller than the previous ones I fabricated from scratch (20 or so years ago). They clear the steering box well. I just need to decide if they come to far into the wheel well too far,

How much clearance to the front fender support is there at full stuff in a SOA rig?

 

[bikersmurf]

Test fit of the ‘new’ 8274. It came on a mount, so for at least the time being I’m going to bolt that onto my existing 1/2” plate mount. Once I fine tune a couple things, I’ll paint it, wire it, and bolt it down for good.

Progress on the P/S mount.

Removed a bolt thats head was rounded off too much.

edit: the stuck bolt was the short on on the right side. I welded a longer bolt to its head to give me something to turn on. The heat from the mig welds likely also helped break it free.

Not pretty but it worked.

Raw materials.

After cutting up.

The extra hardware is to make tensioning easier.

@ToyotaMatt, eat your heart out. It’s still in the design/prototyping phase.

I have to say that your solution is more elegant. For this application I’m going to pull towards the fixed end. I’m hoping the offsets on mine will be close for the need alignment. If not I’ll need to use the hot wrench and ‘adjust’ them. Steel becomes much more cooperative once cherry red.

That it would… but it would look out of place yellow ZINC Gold Plated. Thanks for the offer, but I’ll paint it black like all the other brackets.

The end of this set is in sight.

If you have an opportunity to get all stock parts to mount a power steering pump, compressor, water pump, etc… do it. Adapting parts that never worked together and making them work together is a huge time suck.

PM me and bring it ON !

The adjuster is in and it works.

It’s now incredibly easy to tension the P/S belt. After loosening the lock bolt, I threw an electric impact on the head of the vertical bolt. Once happy with released the trigger and tensioning that belt was done in seconds.

Then I had to fight with the A/C (onboard air) compressor to get its belt tension correct while tightening the one bolt that locks both pumps in place.
