I love my jeep

I love my jeep.  But how did it get its name?

There’s a book by Paul Dickson, “War Slang: American Fighting Words and Phrases Since the Civil War, Second Edition“” that says the jeep is “1, a small, low, khaki-colored car in general use in the Army. 2, a rookie; a recruit.” OR you could go with his quote from another source, San Francisco Call-Bulletin, November 22, 1941, “Do you know why those swift little army cars are called ‘jeeps’? It’s Model G-P produced by that automobile manufacturer–and G-P easily becomes ‘jeep’.” In 1941 Ford was producing a vehicle for the Army that was a model GP. The vehicle pictured in this blog below is actually a 1941 Ford GP.

The unfortunate thing is that the War Slang book does not mention the jeep term being used during WWI or the inter-war period.

If you are interested in finding out more about WW2 era jeeps then you might want to check out my book on the subject: BANTAM, FORD AND WILLYS-1/4-TON RECONNAISSANCE CARS.

It might be a bit too cold to change the oil on your WW2 jeep right now.  However, it won’t be long when you will need to climb under the jeep, turn some wrenches and get that oil changed.

I really do hate dirty oil, don't you?

Occasionally it will be necessary to flush the oil system because of an accumulation of sludge or other foreign material. Here are some instructions from WW2 manuals:

  • Drain the oil from the system after warming the engine to normal operating temperature. Be sure to use CAUTION as the oil will be HOT.
  • Fill the oil pan to half the indicated level with light engine oil.
  • Start the engine and allow it to warm up thoroughly. This will allow the light oil to clean the system. Watch the oil pressure gage, and stop the engine at the slightest sign of low oil pressure. This may be caused by a clogged strainer.
  • When the engine is thoroughly warmed, turn off the engine and drain the oil.
  • Fill to the proper level with the correct engine oil.
  • If the oil filter has a replaceable filter element, inspect it and replace if necessary.
Caution: These are recommendations from WW2, always consider if this practice is considered safe for you or your equipment for proceeding. If you follow these instructions I would use extreme caution and watch closely the oil pressure gauge. I would also try using 10w oil as my “cleaner” and I would fill it till it was at the full mark instead of half. The sump pickup in a jeep may not pickup the oil if it is only half full. I suggest always changing the oil filter when changing the oil. But I wouldn’t change the filter until after the cleaning. Again, exercise caution.

Even I could work on the T-84 transmission, how about you?
Got a spare tire and nowhere to stow it?

There comes a time when your WW2 jeep is just about finished and you begin to look for the little parts to complete the project.  One of those parts is the tire carrier.  You will need to figure out which one is correct for your year model jeep.  So if you need a place to hang that spare tire…

You need to purchase a Tire Carrier. The 3-bolt late style tire carrier is the easiest to use.  It’s almost like mounting a wheel to the axle (with two fewer bolts, of course).

2 Bolt Style Tire Carrier for Willys MBs/Ford GPWs version is also available.  With this version, you will also need a disc that actually holds the wheel on.

Need other parts?  The supplier has many other parts as well.

Don't you just hate it when you hear rattles?
Don’t you just hate it when you hear rattles?

[1] A rattling sound, apparently originating in the clutch, may be caused if the clutch-pedal pull-back spring is disconnected. Connect the spring, and check to see if the rattling is eliminated.
[2] If rattling continues it may due to weak pressure-plate retracting springs or excessive clearance between driving lugs and cover. The clutch assembly must be replaced.

Lots of detailed photos of all three jeeps!

These jeeps are on display at the Veterans Memorial Museum of Huntsville, AL.

Description: The 1/4-ton, 4×4, truck of World War Two started out in the hands of the Infantry and a little company called American Bantam Car Company. Bantam worked with the Army’s Quartermaster Corps to produce the pilot model that was accepted and then fulfilled their initial contract for 70 trucks. During testing of the pilot, both Ford and Willys-Overland were invited to check out this new vehicle. The vehicles were studied in great detail. Soon, at their own expense, Ford and Willys-Overland submitted pilots for testing too. This book covers the production prototypes–Bantam BRC-40, Ford GP, and the Willys MA.

I just love a good book…Don’t you?

A book that has been in my collection for a very long time and is still in print, WW2 Jeep Military Portfolio 1941-1945, is a book worthy of your consideration.  It has a number of period articles and even some from years after the introduction of the jeep to the world.  It isn’t a book that will help you with your restoration but adds a bit of knowledge to your kit of facts to help you understand the jeep.
