'71 FJ40 Meet Jiffy

[TwelveGravity]

Meet Jiffy. I got the name from my Dad, he had a 1947 Dodge pickup of the same color that they called Jiffy back on the ranch in San Miguel.
I recently took delivery of this 1971 40 series 1F 3 on the tree.
From what I understand it was originally a Texas truck that made it's way to California a few years back.
My previous 40 was a purpose built trail rig built by the PO, I finally accepted the fact that it was less and less practical for what I wanted. I picked this on up to start from the beginning.
It will need a lot of work but it is a good start for the weekend driver I want it to be and we'll go from there.
I'll update this with pictures and tid-bits as I go along.

Looks nice in the pictures. (Which we demand more of)

After a good wash & vacuuming the inside I looked it over. Brake inspection, hoses, belts, pulleys.
Most everything was in good working order. All the gauges in the dash work, except fuel level. Most the lights work except turn signals & 1 brake light. There were at least 4 lug nuts on every wheel loose, so those were snugged up. I replaced the battery since it was about 4 years old and the PO has a disconnect on it, stating that something is drawing down the battery while it was parked. I put a fresh set of tires on, the old ones didn't look too bad but they were aged and I would rather have the piece of mind that I wont blow one out. The paint job was a very low effort paint job, the closer you look the worse it gets but there doesn't appear to be any major areas of cancerous rust or body filler.

I'll need to do some digging around to find a manual on the carburetor (Weber). The first drive I went on it idled and ran fine, the drive after that it seemed to miss or sputter at low RPM's and would not idle. I have the original carb in a box, a friend recommended me to send that in to be rebuilt and get rid of the weber. In the mean time though, I would like to make this drive able.

Considering it is already setup with over drive, you've got a good start!

After looking around and reading around I think a few of my first moves will be to ditch the Weber for an original carb. I don't think I want to look at Sniper EFI for it at this point just being a local weekend driver. I will need to replace the exhaust manifold since it is cracked in a few spots and there appears to be an exhaust leak sealant in some spots. Also, the PO told me about a 4wd vacuum leak that needs to be fixed. It looked to me like the 4wd was all mechanical just from crawling in and under the 40 but I was told it is vacuum actuated. So please school me if you have any knowledge on that.

Appreciate it.

It’s the FD knob with the white string/tag on it. Pull it and the cable goes to a vacuum switching valve with 2 vacuum lines going down to a diaphragm shifting unit. It moves a fork that slides a sleeve on a shaft to engage or disengage the 4wd

 

[TwelveGravity]

I was in the garage earlier while it was still under 100 degrees out and was on the hunt for the Overdrive that the tag on the dash indicated.

I found this,

And then I found THIS!

 

[TwelveGravity]

Can someone please school me on this? The tag hanging says "Pull out towards driver"

I was able to find a few videos to learn up on the vacuum actuated 4wd and how that works. Pretty neat as long as you don't have any leaks.

It's the same as the floor shifter except upside down. Push forward for 2H. Pull back to middle for N. Pull back further for 4L. The pin on the side of the shifter is supposed to pull the 4wd knob out to engage the 4wd.

Thank you

Not sure how i ended up here as i was trying to make a post in the RC thread, sorry!

 

[SharpeCat]

Crap i am in wrong thread! Deleted.

Also, i have this thread bookmarked for inspiration at the moment is how i ended up here. Whoops!

I've been wanting to get to wrenching but was unsure where to start or what to do. It felt overwhelming a bit but I pulled into the garage and thought, just get started, somewhere. So I started stripping it down, put parts in storage so I can get to work.

The wiring on this is a nightmare. I've reached out to Matt (Cruiser Matt's Off-Road) to see what we'd need to do to fix it. There's misc wires everywhere, wires that don't go to anything & even burnt wires. There is also a draw on the system somewhere that will drain the battery quickly.

I pulled all 4 seats out and plan to have them reupholstered.

 

[TwelveGravity]

I got started removing the top.

It appears the rim has an attempted repair by A LOT of silicone where the soft rivets have broken and the fiberglass has separated from the metal rim.

The rim is severely deteriorated in some areas

 

[TwelveGravity]

The top will need to be rebuilt so if anyone has a contact that could help with that, would be appreciated.

 

[TwelveGravity]

Removing the top while working in the garage by myself, I had to get a little creative so I didn't damage it more. I used two 2x4's as skids to slide the top from the cruiser to the bed of my truck.

This stuff proved to be a life saver on all the rusted hardware. I think in total I broke maybe 2 or 3 bolts, the rest worked thier way out after a couple drops of this and a few minutes to sit.

Shop supervisor always looking over my shoulder.

The mess of nuts and bolts removed and thrown away.
