Jill asks, “Is the problem the exhaust system?”

 

The carbon and rust clogged mufflers on some vehicles bring to mind the embarrassment of a German musician who tooted the tuba at a country fair. When the band started to play, “There’ll Be a Hot Time in the Old Town Tonight”, nothing came out of the horn but a series of horrible grunts. The horn player had plenty of wind and ambition and the horn was a first class instrument. What the German didn’t know was that while he had gone away to get a cold beer, some of the local boys had stuffed a dead rat into the horn’s innards.

Too many vehicles are going around that have the equivalent of a dead rat in the muffler. Carburetors are designed to work with an exhaust system that has the minimum amount of back pressure, and anything that restricts the free flow of waste gases is going to give a mighty bad influence on carburetion and engine performance.

The quick statement that “Maybe it’s the carburetor”, is just a shot in the dark until you get, right down to brass tacks and locate the exact nature of the trouble. The important thing is not whether the trouble lies in the carburetor or the front bumper – the important thing is to get results – and you can’t get results with snap judgments.

Article is from the trouble shooting series – Automotive Trouble Shooting For WW2 Wheeled Vehicles,Volume 1 and Volume 2.  The books are available from Amazon.com and other fine booksellers.

Does your jeep have a broken valve spring?

Does your jeep have a broken valve spring?  Mine doesn’t but I thought I would ask!

That well-known American sportsman, the jeep factory representative, offered to lay us nine to one that if one valve spring breaks~ the others are not far from breaking too. We’ll lay you ‘twenty to one, he’s right. So to really do the job right and save your self the trouble of replacing the valve springs one after the other, replace them all, when you’ve got to replace one.

Article is originally from the April 1942, Army Motors and available along with much more in Military Maintenance for MB/GPW Jeeps 1941-45.

Do you like to read?  I do.

Do you like to read? I do when it is a good book.  Here’s one…

The Jeep: History of a World War II Legend is a very good book that you might like…assuming you like the WW2 jeep, that is!

The Jeep: History of a World War II Legend

The Jeep: History of a World War II Legend

You might think that a book with only 80 pages would be light on content but the authors, David Dalet and Christophe Le Bitoux do a great job in putting it together.

They discuss “Origin of the name jeep” in one all too short section.  While well written it is light on information. The use of the name “jeep” is associated first with the Minneapolis-Moline Company’s tractor and then the authors mention the Bantam.   There is no mention of the Dodge 1/2-ton being referred to as a “jeep”, especially by the Armor Corps.  There is no mention of the Ford GP.  While GP did not stand for general purpose in connection with Ford, it was the abbreviation for what the 1/4-ton vehicles were and that is a general purpose vehicle.  This is evident when you read the TM 9-803 description about the vehicle.

There are some really great historical pictures in the book, some of which I don’t think I’ve seen before. Color photo’s are also included.  These are photos of the vehicles as they are today (or as restored today!).

Anyway, I own a copy of the book and recommend it to anyone that collects books on the subject jeeps…especially WW2 jeeps!

A beautiful red head in a pinup pose.  Perhaps a WW2 pinup?  GIs loved pinups and sometimes would paint them on their jeeps and other vehicles.

As you can see there isn’t much room for anything large but a skilled artist could easily paint a small picture on the windshield under the window.

People talk about Hummers and such but I say who cares. There’s nothing better than a jeep.  A Ford GPW jeep is even better!

My jeep and I both love fresh clean air. Make sure you do it right.

The WW2 jeep used an oil bath air cleaner assembly.  It was purported to be a very efficient unit.

The air cleaner consists of parts F, G, H, K and J as pictured above.  The filter is pretty symbol to install and use.  Oil is poured up to a certain line marked on the air filter cup (H).   A modern change to the oil bath is a dry filter cartridge insert.  The dry filter replaces air filter element (G) and also includes an adapter to mate the dry filter to the assembly.  No permanent change is affected to the unit.  Anytime you wish to go back to slopping oil about the jeep engine bay–you can!

Over the course of the last 25 years or so there have been a few different dry filter “kits”.  One was sold by Willys Minneapolis when it was owned by Louie Larson.  The adapter was designed by Ray Cowdery (the guy that wrote All-American Wonder).  This is the air filter cartridge and adapter that I have used for nearly 25 years.  The cartridge used with this setup is the NAPA 2036 or WIX 42036.

 

 

 

Plastic Oil Bath Adapter.

Plastic Oil Bath Adapter.

A good friend of mine, “Brother” Callahan designed a replacement adapter in plastic when he couldn’t find one made of steel, like mine.  He made a few and sold a few but it there wasn’t much demand because the cost was just too expensive for the plastic, never mind the cost of the machine work.   These were machined not vacu-formed.  So after making a few of these and not having much luck recovering costs, Brother stopped making them.

Along about the time Brother ended his projector a really sharp guy going by the name Fred-D discovered that you could easily “make” an adapter by buying two “doughnut rings” used in the plumbing of a toilet.  One went under the air filter and another went on top. He said, “…order two Sponge Rubber toilet bowl rings P/N 2793K81 from McMaster-Carr. Phone # 404-346-7000 . They cost $2.71 each…”  That’s a whole lot cheaper than any of the two earlier methods.But why would you want to stop using the oil bath filter?   The dry filter is just a little more efficient at removing dirt and grit from the air.  The dry filter won’t spill on your fender and leave a nice mess on a painted service that absorbs oil.  On the flip side your jeep won’t be as it was.  It’s really just a matter of personal choice.

WW2 Jeep In Action by David Doyle.

World War II Jeep (In Action, 2042) is well worth the small purchase price.  The book contains about 52 pages with more than 100 photographs.  Many of the photographs haven’t been published before or widely seen.  There are also a number of well drawn color profiles and detailed line drawings.

The jeep was originally designed as a command and reconnaissance car to replace the horse and the motorcycle. The jeep was widely used during WW2 from North Africa to Europe and in the Pacific. David Doyle does a good job of presenting each location or area of use with a number of pictures.  He has included pictures of the standard jeeps as well as those used as ambulances, radio vehicles, follow me jeeps on the flight line and armored cars in the field.
