OIL PULL COMMENTS


| September/October 1973


R.D. 2, Middletown, Maryland 21769

I read the OIL PULL TUNE UP article by C. E. Stambaugh in the September-October 1972 issue, with great interest and knowing Bud Stambaugh over the past few years, I feel that he is one of the top experts with Oil Pull Tractors.

His method of adjusting valves on light weights is correct and should be rechecked on a hot engine due to the push rods and rocker arms being enclosed. The older 12-20, 16-30,2040 etc. had open push rods and rocker arms and there was very little difference in valve clearance between hot and cold, due to cylinder heat expansion exceeding open push rod heat expansion.

Now, I would like to refer to the remarks by Frank J. Burris, 35640 Ave. F., Yucaipa, California, which I read with concerned interest.

My reason for writing this article is that I've worked around Oil Pulls many years, beginning with an Old 20-40 purchased by my father in in the early 20s and traded on a 30-50 Y about the time Rumely Company changed to Allis-Chalmers.

Mr. Burris remarks that he discarded the use of a water tank on a 20-35 Oil Pull and is operating the engine on pure gasoline. I am sure Mr. Burris is aware of the danger if this Oil Pull should come up to its normal heat which is over 200 degrees and there should be gasoline fumes in the crankcase. I remember one old 12-20 that exploded in the crankcase from using gasoline and blew both cylinders loose from the crankcase. I also remember a 30-50 Y and a 2545 light weight exploding and blowing the crankcase inspection cover and timing gear covers out.
