My old 1981 SCRAMBLER returns 25 years later

[jbeemer]

Made a little more progress........

The bottom side is pretty much complete except the fuel tank and line.

The relay center and harness are in and routed to general areas.

The water pump is drilled and tapped for the sender that feeds the AutoCoolGuy fan controller.

It would run right now if I plugged the fuel cell line and wires in..............

Awesome. And I’m scratching my head on an LS1 wireing. Your at a whole nother level.

 

[MrBeep]

I'll agree. Your at a whole other level of technology than most of us "Old Time Jeepers"

 

[jbeemer]

Fuel tank and skid were already built . I finished the mounts for the skid plate. It's painted, tank is strapped in and ready to install.

 

[jbeemer]

Wandered down to the shop before work this morning and bolted the fuel tank in. Just need to hook up the lines.

 

[MrBeep]

Getting close!

This is a real nice build. I like following any LS build. Most people think the LS engine is ugly but I beg to differ.

I am thinking of doing something with the cover on mine, maybe just paint,.............maybe custom......

Your engine cover looks good, but I may run into intake clearance on the top of the motor. My plan is to suck cold air from the cowl vent.

Had a good day in the shop

Fuel lines are done.
fuel vents are done.
fuel fill is done.
Fuel tanks wiring is routed and done (other than the fuel pump module is mounted with ZIP ties)
shifter cable is done.
Rear harness grounds are done.
cab and relay center grounds are done.
block grounds are done
tail light wiring is done.
Fitting welded on the radiator for the steam vent.
grill is in place with 2 bolts.
Fan has lots of room and the accessories on the front of the engine are accessable.

getting VERY close to first startup in the Jeep.

Sorry, no cool pics today

But IT RUNS


Now I have to get The coilovers, fans, some switchs, the gauges, and loose wires, so I can drive it.

Uh......VIDEO........

Yes I know, I was slacking today

A little bit of a update. After the excitement of first start I ate some lunch and went back out to the shop. warmed it up, circulated the antifreeze, and topped of the power steering. Which puked out the vent when I shut it off because of all the air still in the system.

I did get the front coilovers mounted back up. Looks like I gained about a inch of ride height, that equals about 120 lbs lost.

The Autocoolguy fan control is mounted and wired inside, just needs to be hooked to the fan.

The switch panel is mounted and wired.

In the pic you can see some black plastic conduit. I ran those from the left side of the steering column to the center by the gauge panel and behind the glove box. That way I have a place to run future wiring once the AC is back in and blocking under the dash. The relay panel for my lighting and transmission fans will be in the old glove box hole.

I'm excited! Get'er done, snows a come'n.

Soooo I had a little time today......

finished up some "test drive wiring" (wire nuts are ok for test drive........right??????????)


did a trip down the driveway and back.

Then I battled limp mode, after limp mode, reduced power, limp mode,

There was everything from module eprom failure to trasfercase high range incorrect codes.

after several reflashes I had it drivable, but not right. then I turned off "brake torque management" That made it come to life. I have a brake pedal position low code that has been coming up. Not sure if it's adjustment, learning, or wiring. But that is most likely some of my "limp Mode" trouble I was having.

Hoping to do a drive on the road tomorrow.


Here's a couple pics of the quality test drive wiring and a short crappy video of the very first trip with the new motor.

Awesome! 102 degrees in December aint bad either.lol

That was the trans temp. needed to keep an eye on it. The huge cooler I have in the back is all plumbed in, but no fan relays yet, and not much airflow. must be good, it never went over 165*

 

[jbeemer]

If this works........
Here is a link to a Facebook video a friend of mine took today during testing.

quick top. Nice thing is 2 bolts and some screws its off. Super light, no seat belts to reroute

Sent from my SM-G900V

That's actually pretty dang sweet.. I may have to pick up a CJ7 top...

Had a GREAT day cruising the Scrambler with the new motor.

The drivability is just awesome, And I had no complaint's with the old motor. But the shifting of the 6l80 the flat torque curve of the L83 are just cool.

I put about 150 miles on it today, and no big surprises. I have a leak in my steering box that showed up Tuesday when we were acting like two 8 year olds that just got a go cart, doing 65 MPH passes in the rutted corn field. The top cover were the adjustment stud is located is leaking out of the cover. I'm not sure if it was just old, to much pressure, or my hydraulic ram over traveled the steering box. Next step is to check pressure of the pump. It is supposed to be 1600 PSI. The old stock pump was 900 too 1100 psi.

Now it's back in "storage" so I can get some of the "honey do" list done. Then it's just a matter of finishing wiring, cleaning up, and finishing loose ends.

The 10" Samsung tablet in the center under the gauges is working out great. I was worried about the GPS picking up satellites with the aluminum above it, but it works great. The Torque app has any extra gauges I need, and some fun stuff too.
