1986 AMC Eagle


Recommended Posts

I have a long story with this car. It was given to me by my employer when I was 12. It needed a motor, so I bought a parts car and swapped the motor. 

I then sold the car to buy my MJ. I don’t regret selling it for the MJ, but I had to jump on the opportunity to get it back. 
 

Here is everything that I had done to the car along with pictures when I had it before. 
 

1986 AMC Eagle Station Wagon

258 Inline Six

3-speed automatic transmission

Shift-on-the-fly transfer case

2:73 gears

106,000 miles on body

105,000 on engine from a 1985 Eagle

Rust free body from down south

Interior in good condition-a few tears in front seats, tiny hole in rear seat- about an inch in diameter

Spare front bumper, window trim, and transmission

 

New parts:

Axels

Starter solenoid

Vacuum lines

Spark plug wires

Heater hoses

Brake lines around master cylinder and on rear end

New fluids in transfer case, engine, master cylinder, and transmission

I have no idea how many extra parts are still with it, but the guy also said that he has a bunch of parts too

Rad. I’m a sucker for these cars. :L:

It’s going to be a fun build too, although it’ll stay mostly stock. Maybe a 2” lift and 235/75R15 tires with 3.54 gears.

Here is the current state. 
The car is in PA. I am in WI. I am looking into some shipping options. If I can’t get it shipped reasonably, we are planning to drive there and back the weekend of the 19th. Since I sold the car, the owner says he has done nothing with it. He is planning on getting it fired up this weekend and will try to send me more pics then. 
 

This car is going to be my year round driver. When I get it back, I want to take it apart and fix any rust (was an AL car, so it is very solid) and then rust proof the ever living snot out of it so it will survive. I will also have to keep it clean in the winter.
 

I want to lift it a couple of inches and run 235/75R15s in an All Terrain flavor. I also want to modify it in a period correct 80s kind of way. 
 

It isn’t going to be painted anytime soon either. The red may get redone, that is TBD when I get the car back.

I'll love to see her restored.

Believe me, so would I. Being 17 though doesn’t give me much extra time, space, or money to have 20 restored 80s vehicles plus a newer daily driver for winter duties.

I LOVE those cars! Helped a buddy build one way back in the day. It was a 2 door 4 speed. Lifted a little with a ton of trimming to fit 31/10.50/15.

They are a ton of fun! This car has a ton of stories during my 2 years of ownership, maybe I’ll have to tell some.

Have you considered getting a donor XJ for a full drivetrain swap? 

I have, and it is not out of the picture, but you can’t find a Cherokee around me with less than 200,000 miles on it for less than $1,500.

When I had this car the first time, we took it out in the snow once I got it running. We jumped it through a snowbank and drifted it around in the yard. My cousin even took out a tree with it while slaloming in the yard. No damage was done to the car. We had a ton of fun with it and part of the reason I want it back is for the sentimental value.
 

Here is the look I’m going for in terms of wheels and tires. 2” rear spring lift, 1” coil spring spacers, and 235/75R15s with some fender trimming behind the flares. I will trim on the fenders, but not the flares.

Sorry if I'm a party pooper, but I think the pics you shared of it as it is right now look way better than the lifted one with XJ wheels!

I might run those turbine wheels, but the rear end is sitting about an inch lower than the front end, so something needs to be done with the suspension. 
I do love me a set of turbines on these cars. 
Don’t worry about being a party pooper either. I love different ideas!

There is NO cooler vintage wheel than turbines.  Forget the xj wheels they look like poo

Yeah, my car does have XJ wheels and they will be going away. I might try to get some XJ turbines to replace them.

You need those odd 5 spoke XJ waggy rims from 84-86. 

If I found a set, I’d consider it, but I honestly think I like OEM turbines the best on Eagles.

It wouldnt matter mj style or stock eagle style. Just keep the turbines.

The Eagle and MJ shared the same turbines. These were some aftermarket ones that we had laying around.

I’m kinda digging the Jeep Golden Eagle stripe. Maybe one in maroon would look sweet on this car. I'm also digging the aluminum slots.

For future reference in case I decide to do an AW4 swap:

 

//THE BIG AW4 INSTALL POST - very long post incoming
gonna have to break it up and caption the process with the pictures so hopefully this all makes sense. 
there are a couple small issues i need to work out, but overall this is a good picture of what it's going to take if you're interested. for what it's worth, i managed to perfectly maintain AMC's original power band and highway engine rpm speeds despite gearing, transmission and tire size changes. it's a drastically improved driving experience - still feels like a vehicle of its vintage, but with more modern throttle response, acceleration, and driveability. 
--------------------------------
So why do this? If you've ever dreamed of an automatic with overdrive, this is what you've been dreaming of. This is by far the easiest, and best, overdrive automatic to adapt and install. According to the internet, the AW4 was developed jointly by AMC, Aisin and Borg Warner - hence the Aisin-Warner name. When properly cooled and maintained, the AW4 is a very dependable and long-living unit. Its use of a standalone TCM allows it to be used behind a carbureted engine and keeps wiring as simple as possible.
First things first - if you're the kind of person that is intimidated by electrical stuff, this won't really be the task for you. You'll need to be able to read and understand wiring diagrams to correctly assemble the transmission harness and integrate it into the existing wiring where needed. 
I work on cars professionally, so while I'm attempting to write this so that anyone with minimal knowledge will understand, I will probably overlook something that is second nature for me at some point. That said, this definitely isn't a job you can graduate to after changing your own oil a handful of times - it's relatively straightforward, but a bit tricky at points.
There are a couple things I haven't totally nailed down yet. One of which is the front driveshaft. The original will be too short; the donor will be too long. I haven't bothered with the transfer case shifter since I don't have a driveshaft. I made new linkage rod for the original shifter to attach to the new transmission. It's a bit stiff getting out of park and the detents don't line up with the original shifter, so I may go with the Jeep shifter and cable at a later time.
There's enough information on forums about the various differences from year to year so I'll just link to those rather than summarize. I used a 1989 TCM, 1989 TPS, and a 1991 transmission. Up thru 1997 any year TCM will run any year transmission if you're forced to mix and match like I was.

DONOR VEHICLE PARTS NEEDED (preferably all from the same vehicle)
-transmission AND transfer case (231 or 242)
-starter w/solenoid connector
-flexplate and bellhousing tin plates (keep all bolts)
-transmission control unit
-as much original wiring as possible with at least connectors for the TCM, TPS (read note below), and the two transmission connectors at the firewall
-both transmission and transfer case shifters with cable and linkage
-cooler lines
-throttle body
-throttle cable bracket
-crossmember
NOTE ON THROTTLE POSITION SENSOR
I recommend using the RENIX ERA throttle position sensor regardless of which TCM you use. All TCMs will use a 5v reference and this sensor will work with any system. The renix sensor is a dual sensor that is capable of reading 0v nominal at idle or 5v nominal at idle depending on which side of the sensor you use. The sensor has an arm pivot that makes it MUCH easier to adapt than the later style sensor. Connectors can be obtained new thru parts stores if your donor vehicle does not have what you need. If using a chrysler era TCM, you'll need a 5v regulator to provide the signal voltage. Renix TCMs provide the 5v signal.
WALKER PRODUCTS 20091094 - is a complete kit with sensor and both pigtails.
STANDARD MOTOR PRODUCTS TH67 - sensor only
STANDARD MOTOR PRODUCTS HP4460 - 3 wire connector for use with chrysler era TCM
STANDARD MOTOR PRODUCTS S555 - 4 wire connector for use with renix TCM

NOTE ON DRIVESHAFTS
If you use a slip yoke eliminator kit, you can use the original Eagle rear driveshaft. This worked for me both on this install, and an AX15 manual transmission in an SX/4. The overall length of the transmission and transfer case assembly is within an inch or so shorter of the original 998/129 assembly. However in this situation, the AW4 is longer and the 231/242 shorter which makes the original front shaft too short. Additionally, i do have an 8.25 rear axle installed which moves the pinion yoke about another inch forward which may affect whether the original driveshaft can be used with the original eagle model 15 rear axle - I'm not sure here.

HIGHLY RECOMMENDED NEW PARTS
-slip yoke eliminator kit (unless you want to have a driveline shop modify from the donor)
-USA STANDARD GEAR USA41198 u joint u bolt kit if using SYE
-large external transmission cooler
-transmission cooler hose, clamps, etc
-transmission mount
-EAGLE BRAKE SWITCH W/CRUISE and connector (if you don't already have cruise control)
-1000-1300 ohm resistor (transmission control resistor on diagram)
-fluid/filter/gaskets/seals
-misc wire/battery cable/heat shrink/eyelets
-misc sheet metal for brackets as needed

WHAT MUST WE ADAPT?

The transmission crossmember will need to have much of the middle section removed, a new section added to the rear, and reinforced appropriately. I'll credit Paul Schexnayder here for the method I used, though my work is not nearly as nice as his.

We'll need to adapt the throttle bracket to connect the transmission throttle valve (kickdown) and mount the TPS. It's discreet once complete.

We'll need to adapt the donor throttle cable bracket to properly anchor the throttle valve cable.
I've removed the original engine control module and associated wiring, so its location in the passenger kick panel and harness grommet were ideal to reuse for the TCM and the new wiring. If you're still using the original system, you'll have to find another home for it.

THE OVERALL PROCESS
Remove the original transmission, flexplate, starter with cable, kickdown and shifter linkage, transfer case vacuum lines, and cooler lines.
