1-1/2 HP Challenge

Content Tools

39/4/1: Challenge Engine I would like to restore this engine. It is a 1-1/2 HP Challenge made by Challenge Co., Batavia, Ill. I need things like a piston, timing gear and head. I would like to hear from anybody who has one of these engines, and could greatly use any of the above parts.

Any help will be greatly appreciated! Don Newcomb, 532 Kirk Road, Rochester, NY 14612; (585) 227-2091;

39/4/2: Caldwell & Co. Enclosed are pictures of what, I don't know. Could any one identify what this is? The tag on the base says: Manufactured in U.S.A. for E.R. Caldwell & Co., Bradford, Pa. Loyd A. Fox, 6183 Main St., Jane Lew, WV 26378-8502.

39/4/3: Stuck IH Help! I acquired a very rusty IHC Model M, 3 HP. I need tips on removing the pulley and flywheels. I'm spraying penetrating oil daily on all parts. Can heat be used on the cast parts? Thanks, Ronnie Eisert, 2027 Ball Diamond Hill Road N.E., Lanesville, IN 47136-8136.

39/4/4: Waterloo Boy

Q: A friend and I have found a 6 HP Waterloo Boy engine in a farm grove. It has been there abandoned for 50 years or more and needs much work, but will be a fine engine when restored. The serial number is 24876. Can you tell us the year, correct color and pin striping? A picture would be a great help. Raymond Wickham, Box 402, Dumont, IA 50625-0402; (641) 857-6672;

A: Your engine was built in 1911. Wendel's Notebook lists DuPont 2564 dark red for early Waterloo engines such as yours and DuPont 5316 for later engines. Note, however, that some were painted gray, for which Wendel lists Sherwin-Williams 4030 gray.

39/4/5: IHC Famous

Q: Recently I bought an IHC Famous 2-1/2 HP hopper-cooled horizontal engine. I need to know what year it was made. The serial no. is GA 1708.

I know it was painted red, but the flywheels show traces of white or cream-colored paint. Is this original? Also, I need a parts book, complete carburetor, fuel lines, fuel pump and igniter. Please help, even if the parts are only good for patterns.

Wesley Faust, 1153 White Chapel Drive, Central Point, OR 97502; (541) 664-9119;

A: Your engine was built in 1911. As for the paint, after almost 100 years anything is possible. Assuming the paint is original, it's possible what you're seeing is a primer coat.

You can order a reprint of the original setup manual (which also includes a basic parts listing) from GEM. The book is item no. 1066, costs $5 and can be ordered by calling (800) 678-4883. As for parts, look through the classifieds in the back of the magazine or contact one of the many engine parts suppliers who advertise in GEM.

39/4/6: Unidentified Christmas Present I acquired this engine on Dec. 22, 2003, which made it a nice Christmas present.

I haven't been able to identify the engine. I sent pictures to three engine friends and still no luck. I am hoping someone in engine land may be able to identify it. As you can see, there are a lot of pieces missing, but the engine is free and the cylinder looks good as new. Howard L. Abrahamson, 2145 Shilhon Road, Duluth, MN 55804; (218) 525-4069.

39/4/7: Harvest King Senior We recently acquired a 'Harvest King Senior' garden tractor that was apparently sold through the Spiegel catalog. It has a Wisconsin Model AK engine, with the size shown as 2-7/8-inch by 2-3/4-inch. We would appreciate any information that anyone has on what year it was manufactured and who originally built this machine. Bob Lundberg, 2910 Malone Drive, Panama City, FL 32405;

39/4/8: Maytag Engine Fuel For Maytag engine fuel, I have been told that chain saw fuel mix should not be used. I understand that non-detergent engine oil should be mixed with the gasoline. What mix ratio of oil to gasoline should be used? Also, what weight of oil is recommended?

39/4/9: Witte Engine

Q: I am trying to find some history on a 1925 Witte 2 HP engine, serial no. B26309, I have. Back when C.H. Wendel was doing the Reflections column, he was able, on some Witte engines, to supply the original owner and place of purchase. Is there any way to find this information?

Also, am I correct in understanding that American Gasoline Engines Since 1872 is no longer in print? Are there any plans to re-release this book? It seems that at one time there was talk of a second edition. Vernon Achord Jr., 14218 3rd St., Santa Fe, TX 77517; (409) 925-8029;

A: We contacted C.H. Wendel, and unfortunately he doesn't have any information on your engine. As to Wendel's book, we know that he's working on getting it reprinted, hopefully in the near future.

39/4/10: Witte Engine, Take Two I recently bought a 4 HP 1905 Witte vertical hit-and-miss engine from a collector in Arizona. The seller believes that there are only two of these engines known to exist. I would like to know if any of your subscribers know the whereabouts of other Witte's of the same type. I would love to contact anyone with information on this engine, and in particular a picture of the igniter trip mechanism. George Best, Beaverton, Ore.; or (503) 649-3576.

39/4/11: Fairbanks Morse information

Q: My father restored this Fairbanks Morse engine and would appreciate any additional information someone might have.

It is a Fairbanks Morse flat-head six-cylinder gasoline engine. The tag on the engine reads Fairbanks, Morse & Co., Chicago, Ill. The model number is FM72, unit number FN3037 and engine number 169797. It was used as a stationary engine. That's all we know, and thanks in advance for anything that can help us. Duane Slayton, 10925 11-Mile Road, Ceresco, MI 49033;

A: We cant find any references for a Fairbanks Morse Model FM72. Going by FM serial numbers, the engine should have been built in 1916, yet we've never seen a flathead six-cylinder FM, let alone from that era. Our assumption is this engine was sold - but not made - by FM.

39/4/12: Challenge, Take Two I am in the process of restoring a 1-1/2 HP Challenge engine with solid disc flywheels, serial no. 27774. I would like to know the right color for this engine, as well as the year made. I would also like to know the dimensions for the fuel tank. Any help would be greatly appreciated.
