Tom Jennings' AMC/Rambler pages

26 mar 2020

formerly, world power systems

Here are my AMC (American Motors) and Rambler pages all in one place. Most of the information derives from work on my own cars or related research. Emphasis is on 1958 through 1969 AMCs and Ramblers, especially suspension and brakes, six cylinder engines, the transmissions available for the sixes (much more limited than those available for eight cylinder cars), general chassis, electrical, etc.

All of my cars are long-distance and daily drivers, so my concentration is on problem solving and reliability solutions while keeping them "all AMC".

Rambler 195.6 OHV engine

The Rambler 195.6 OHV engine Endurance, reliability, and performance modifications to the Rambler 195.6 ci OHV engine.


Changing motor mounts the easy way (AMC 199, 232, 258) This sequence of actions makes the job fairly easy.
Home-made front suspension toe-setting tool An easy to construct and use tool for setting front suspension, front wheel toe-in.
1958 to 1963 Rambler American front suspension The 1958 through 1963 American suspension can be daunting to work on. I've solved many of it's problems and have worked out solutions to reliability and replacement parts. This work applies to the 1950 up Nash double-wishbone suspensions. See the Rambler Roadster for what it is capable of.
1958 to 1963 Rambler American suspension performance mods My Rambler Roadster is based upon a 1961 Rambler American, and it handles very well, due to advanced work on the front suspension described here.
1963-1964 Classic/Ambassador front suspension trickery 1960's Rambler "big cars" (Classic, Ambassador, etc) front suspensions are excellent designs in spite of their reputations for difficulty. They are subtle, and easy to assemble right if you follow this general procedure.
Hot-rodding drum brakes Drum brakes have a bad reputation mostly (not completely) based on examples suffering from years of neglect. When 50+ years old they need more than just new shoes and drums. And with inexpensive modifications they can be made to compete with small disc systems in demanding applications. I've run hot-rodded drum brakes for years in Los Angeles freeway commutes and they they give small discs a run for their money.
Easy, cheap replacement for the windshield washer foot pump check valve Original style replacements don't (aaffordably) exist. If you don't mind this non-standard look this works as well or better, uses common inexpensive parts. A five-minute fix.
A real fix for your sloppy 1960's column shifter The column mechanism in column-shift cars after 50 years of service wear out. They get sloppy, pop out of gear, in general degrade the pleasure of driving. The problem is that the metal components wear out. Here's a fix for this chronic condition.
Modern (1970-up) AMC strut bushings There are quality and installation issues with two-piece strut rod bushings. Here's a look at the various designs available.
1963-1964 strut bushing fabrication The strut bushings for 1963 and 1964 (maybe others) Classics and Ambassadors are not available and later parts look similar but do not fit. Here is a solution to fabricating a replacement that's suitable for daily-driver use.
John Elle's 1970-up AMC front spring perch fix The front suspension on 1970-up AMC cars has a coil spring perch containing rubber bushings that wear and fail, and have historically been very difficult to find. John Elle worked out a replacement using inexpensive and generic urethane bushings. It assumes the metal parts are OK, but they usually are.
An electronic replacement for instrument panel gauge voltage regulators Instrument panel gauges use an electro-mechanical voltage regulator that is either unobtainable or expensive and hard to find. Here is an all-electronic replacement using a common part.
1958..1963 American steering gear (Gemmer) Pre-1964 Rambler Americans, and probably a lot of Nash cars, use this tiny little Gemmer worm and sector steering box. Needless to say after 60 years it's worn, sloppy, and probably out of lubricant. They are surprisingly easy to rebuild. It's a decent design, and a tight steering box makes driving a pleasure.
Replacing AMC/Rambler Motorola alternators with Delco 10si There's nothing wrong with the older Motorola alternators other than they're old and expensive to replace. Most of the Moto's out there are "rebuilds" missing tag data and other critical information. A new Delco 10si, with warranty, is half the cost of the Motorola voltage regulator alone. The "three wire" Delco can be attached to the AMC wiring harness with no cutting or modification.
AMC and Rambler dash knob removal Why is it that automotive instrument cluster, knobs, levers, cranks, dials, etc are so weird and strange? The 60's and 70's Rambler and AMC wiper knobs in particular, even with the factory Technical Service Manual it's not easy. Here's photos of the mechanism.
Automotive LPG Fuel In the late 1980's I converted my 1963 Rambler Classic Cross Country wagon to LPG as a motor fuel, and drove it for 20 years without gasoline. It was great, except for when it was a huge PITA. Here's an electronic copy of the how-to booklet I sold 1200 copies of through the Real Goods Trading Company back then.
Renovating a rusty gas tank Making a rusted old gas tank as good/better than new qith Caswell's Phenol Novolac fuel-proof epoxy and a lot of work.
Home-made 1970-up AMC spring compressor As you'll find out when you go to do the job, it's difficult to find a spring compressor that actually fits 70-up front springs. They're 6.5" diameter, about an inch larger than most. Here's how I made one from scrap.


Documentation of work done on a car or project that doesn't rise to the level of "How-To".

How and why oil pressure senders fail
I had two oil pressure senders fail on the road and at speed, bright red OIL PRESSURE FAILURE lamp scaring the crap out of me. I identified the failure and have a fix that has lasted, so far anyway.

Early Rambler-American-specific projects

I've spent a decade doing decidedly non-stock things to this chassis and engine, on two different cars: a 1963 440 Twin Stick, and a 1961 base model. It's a tough car to drive daily; though of very high quality of manufacture, it embodies very old engineering, and in stock form the demands of modern driving stress it to failure, and parts are hard to find. So I ended up doing a lot of one-off repairs and customizations that eventually led to the Rambler Roadster. The work below precedes the Roadster work. Most of it is one-off customizations to the '63, one step at a time. Later work will therefore contradict earlier statements, etc. I've tried to sequence these pages in a way that reveals the progression.

Cars I've owned and worked on or built. Many of the project pages above refer to documents within the 1963 Rambler American page below.

Rambler Roadster
A roadster made from a 1961 Rambler American base model; light weight open car (2250 lbs), custom wishbone rear suspension, home made front suspension, heavily modified engine, five speed transmission, four wheel disc brakes. This is the true sports car AMC could have made.
1963 Rambler American hardtop
Restomod work on my 1963 Rambler American 440 Twin Stick hardtop. Many of the early American project pages above refer to pages within.
My 1963 Rambler Classic 550 Cross Country Station Wagon
I drove this car for 21 years, best car I ever had probably. I put 350,000 miles on it, one engine and two or maybe three full transmission teardowns. Never failed me on the road.
1963 Rambler Classic 550 Cross Country, detail pictures, March 2011
I took a bunch of detail pictures of my wagon before I sold it. One of the few car regrets I have was selling this wagon, though it was driving me crazy at the time.
My 1970 AMC Hornet
Restomod project for a 1970 Hornet; 1983 258, Torqueflite, in diary form.
My 1975 AMC Levi's Gremlin X
I bought this in October 1998 from a small car lot in San Jose Calif. My first and probably only actual restoration.
AMC's 1970's typography
Some notes on the logo and text on the rear ofa 1975 Gremlin X, and a matching typeface found.
My 1979 AMC AMX (aka Spirit V8)
My third-favorite car of all time is this '79 AMX, which I couldn't really call my "AMX", so I called it a Spirit V8, which is what it was. It had quick steering, 304-V8, a torqueflite (later a 4-speed). I bought it in Massachusetts, and took it with me when I moved to San Francisco in November 1983.

Navarro Rambler six

On 14 July 2005 the remaining contents of Navarro Engineering's (Barney Navarro) shop in Los Angeles was auctioned, mostly shop equipment. I went to ogle the twin-turbo Indianapolis 500 engine, ended up buying a load of exotic Rambler test-mule engine parts.
