A BRIEF WORD
Recently the GEM office received a technical title for review. From the Proceedings of the Institution of Mechanical Engineers in Great Britain, it is entitled, Combustion Engines-Reduction of Friction and Wear. It is available through SAE Customer Service, Dept. 676, 400 Commonwealth Drive, Warrendale, PA 15096.
As we all know, friction remains one of the greatest problems in the internal combustion engines. For pistons to fit the cylinder without blow-by, they and their rings must be very accurately fitted. Doing so raises the level of friction, and this is then minimized with the use of proper lubricants. This title approaches the problems involved in piston skirt friction and the influence of the oil ring type and design on fuel and oil consumption. Another section deals with the measurement and reduction of piston assembly friction. Other sections give an in-depth look at design analysis of various components such as cam and tappet design, piston ring performance, and other technical areas.
This title, while very well written, is highly technical in nature, and is definitely not armchair reading. It does however, provide valuable technical information regarding the subject, and certainly is evidence that a great deal of research has taken place since our vintage engines made their appearance. We recommend this title for those conversant with higher mathematics and familiar with this phase of engineering technology.
Our queries this month begin with:
25/2/1 Unidentified Q. I recently found this old tractor in a junkyard. I would like to know its name, when it was built, and if anyone can supply information on the clutch, as it seems to have been tampered with. Melvin Long, 540 Bartlett St., Harbor Beach, MI 48441. See the photo.
25/2/2C Q. See the photo of old tractor in a junkyard. It is missing air cleaner at Tillotson carburetor. The air cleaner may have been some sort of round cannister filled with shredded steel or similar material. It is also missing the governor linkage which must be a device driven off the fan and connected directly to the carburetor butterfly as there is also an arm on bottom end of butterfly to hook on governor return spring. Would also like to know the horsepower of the engine. Can anyone help please? Joe Menold, 115 South 16th, Sabetha, KS 66534.
25/2/3 IHC 6 hp M Engine Q. I have a 6 hp McCormick-Deering, s/n C28754 of 1923 vintage. The engine is on the original cart. I would like to know if the cart is the same color as the engine, or different. Also if there is any decal on the cart. I would also like to have either the plans or a photo of the seat/battery box which was on the front of the cart. This engine originally belonged to my wife's great grandfather, so there is a family sentiment in getting it running and restored again. Any help will be appreciated. Richard W. Hankel, RR 1, Box J64, York, NE 68467.
A. We believe that the paint color was the same dull green all the way through, engine, trucks, and all. We also doubt that any decals were used on the trucks, but for display purposes at least, one photo shows the word 'INTERNATIONAL' painted on the sills. The tool box was a wood or metal box the width of the sills, and mounted between the flywheels and the seat. The seat was of pressed steel and mounted on a steel stem similar to that used on mowers, binders, and the like.
25/2/4 Case VAS Tractor Q. I have recently purchased a 1952 Case VAS tractor. It is distinguished from other VA series tractors by its off'set engine, similar to the Farmall A and Cub.
In literature searches at the Ontario Agricultural Museum , I have been unable to find any references to this tractor in Case advertising material or manuals. The only description I have seen is in the 1954 and 1955 Red Book. Even the Case Heritage Foundation's own publication, when listing the Case tractor serial numbers, neglected to mention the VAS model. Can anyone explain what has happened? Any assistance would be much appreciated, as there are some minor non-essential details missing. Any communication with other VAS owners would be greatly appreciated. Cliff T. Jones, RR 2, St. George, Ontario NOE 1N0 Canada.
A. Our current research on a J. I. Case book is not yet organized to the point where we have all our material sorted by specific models, therefore we can't be of much help in this instance. We will be most interested in hearing from other VAS owners however, or for that matter, anyone with information on these elusive models.
25/2/5 Ingeco Engine Q. I recently acquired an Ingeco engine, similar to the one shown on page 243 of American Gas Engines. It is 1 1/2 hp, Type AJ, s/n 5803. At present it has a spark plug for ignition, and is equipped with a Briggs & Stratton carburetor. First I would like to know about when it was built, and the proper color. Also, I would like to get in touch with someone having one of these engines so that I can duplicate the missing carburetor and ignition parts. Any help will be appreciated. Donald E. Bowen, 12665 Sundance, San Diego, CA 92129.
A. We currently do not have the correct color match for Ingeco engines, but perhaps one of our readers might be of help. Likewise, we hope there might be a reader having one of these engines who could furnish Mr. Bowen with the needed dimensions.
25/2/6 Wico EK Parts Q. Is anyone making parts for the Wico EK magnetos? The armature guide pin assembly is a hard part to repair. Wm. C. Kuhl, 464 S. 5th St., Sebewaing, MI 48759.
A. We know that several GEM advertisers, Starbolt, Pedersen, and others, have at least some Wico EK parts available. We also know there has been talk in the engine world of making the back casting which also carries the steel armature stud. Whether any of these people, or for that matter, anyone else, had made or is making this part, we do not know. Perhaps some of these folks will respond, updating our readers on what might be available for the Wico EK magneto.
If you haven't yet had problems with the Wico EK, we'll 'bet the farm' that you probably will at some time or other. From the mechanical, and from the electrical viewpoints, the Reflector has always thought that this unit left something to be desired. Mechanically, it requires precise adjusting of contact points, and the armature guide pin to which you refer is subject to wear, as is the armature hole. When the pin wears sufficiently, it allows the armature to kick off unevenly, and no longer do you get the clean break required for the maximum spark. From the electrical side, the voltage induced at the break of the magnetic circuit is fairly low under the best circumstances, and if the armature hole or its mating guide pin are worn, the induced voltage drops still further. Another culprit is a gummy accumulation of grease or oil on the guide pin; this too will give a sluggish break. We've toyed with the idea of setting the casting with the guide pin on a faceplate bracket so as to get the pin to turn concentric with center. Then it would be possible to clean up the pin and make a bushing to fit the armature so as to restore this section to the optimum once again. The problem is that the setup is awkward and difficult, to say the least. Some reader input on this subject will certainly be welcomed.
25/2/7 Paint Colors Q. I recently acquired a Fairbanks Morse Type Y, Style HB engine; also an Ohio 8 hp engine. What are the proper colors? Glendon E. Carber, Buds Power Equipment, Harrington, ME 04643.
A. We would suggest that the FBM 'Y' engine should be a greenish black- so dark that it is black with a tinge of green visible. Indications are that the shade changed from time to time, but this seems to be close, although our FBM Model 32 was unquestionably finished jet black. The Ohio is deep maroon, comparable to DuPont 143.
25/2/8 Douglas Pump Q. Can you tell me the color and year built for a Judson 1 hp engine, s/n V98087? Also does anyone have any information on the pump shown in the photo? It is a W & B Douglas, made in Middletown, Connecticut. Don Stier, 3706 E. 22, Spokane, WA 99223.
25/2/9 Standard Twin Q. While attending the Tri-State Engine Show in Portland, Indiana I bought two Standard Twin Garden Tractors. One is s/n 402C6388, and the other one is missing the serial plate. Is there any other place to look for the s/n on this tractor. I need information on when they were built, proper colors, and similar data on these tractors. Thomas Kruse, 6232 Cedar Lane, Miamisburg, OH 45342.
25/2/10 Royal Engine Co. Q. In helping an arts and craft association with information about an engine in their possession, we write you to ask for any information on the below photo. From its sign, it is stated to have been made by Royal Engine Co., USA, and it follows by Model No. FB 3775. Any help will be appreciated. Tore Blom, Rubens 533 91 GOTENE, SWEDEN.
A. This engine was sold by Royal Engine Company, but was actually built by Nelson Bros. Company, Saginaw, Michigan. The particular style shown in the photo is not included in the selection of Nelson Bros, engines illustrated on page 333 of American Gas Engines.
24/10/5 Walter A. Wood Engine From Alistair Forteath, we have received the following in response to his earlier query:
I am writing about my Wood engine which you featured in the October issue of Gas Engine Magazine, 24/10/5. Due to the article in your magazine I have received letters from a Mr. W. H. Pine in America and Mr. P. Knight from England. Also I have a rubbing of the nameplate for another Wood engine owned by Mr. R. Cuthill. It is only thirteen numbers different than mine. This is the only other Wood engine I know of. I would like to thank those who have helped me with information on a most unusual engine.
Due to a very large column last month, we are a bit short on letters for this issue. Take heart though, the next one should be a biggie! Just as we are winding up this column another large packet of material has come in from the Stemgas offices, but due to the usual time constraints, it won't be dealt with until the next issue. It's like this folks- you don't like it when the magazine arrives late; and when ye olde Reflector is the one holding up the works, that definitely can be just cause for it being tardy in arriving.
Quite honestly, it amazes me how the Stemgas folks manage to get each issue of GEM done in time to start on the next one-it surely must take some organizing and planning. I've never been a creature of habit, and surely will never take any awards for getting things done in time, despite intensive efforts to the contrary.
As this column makes its way to GEM in early December of 1989, the Reflector is already beginning some cogitations on next year's engine projects. At the top of our list stands a 4 hp IHC Mogul which we purchased last fall from our lately departed friend, Richard Wigim of West Liberty, Iowa. Those of us who knew Dick knew several months ago that the end was fast approaching. Yet, even though the quality of life had waned, it still leaves an empty spot when our friends pass away. Since the little Mogul came from such a good friend, and since this writer has a special liking for Mogul engines, we are proud and happy to have this one in our stable.
An obituary for Richard Wigim is included in this issue.
