Typical solutions for automotive strength problems are complicated by such variables as driver habits and road conditions, but the inclusion of a safety factor when designing for fatigue loading modifies these intangibles to some extent. Two different loading systems are discussed in this article to demonstrate the application of formulas for measuring magnitudes of loads and for estimating frequencies of fatigue failure in road test experience, service mileage, information, and strength comparisons. The author emphasizes that such statistical calculations, used in place of former rule-of-thumb methods, produce more realistic safety factor values and also provide a faster and more economical approach toward achieving long life and reliability of parts.

A brief review of the testing of automatic transmission fluid for compatibility with seals is presented. The total immersion test used in fluid qualification, while apparently effective in predicting the compatibility of fluids and seals in service, does not correlate well with transmission tests with respect to hardness change of piston seals. The Dip-Cycle Test, developed to overcome this limitation, is a procedure for alternately immersing seal specimens in the test fluid and suspending them in the hot air-fluid vapor atmosphere above the fluid. Correlation of the Dip-Cycle Test with transmission piston seal results is much improved over that with the total immersion test. It is the purpose of this paper to review these developments and to present an improved test procedure (dip cycle test) for evaluating the effect of fluids on transmission piston seal materials.

Material--SAE 1010 or SAE 1111 steel or equivalent. Clevis pins shall be supplied either soft or cyanide hardened as specified. Clevis pins must be free from burrs, loose scale, sharp edges, and all other defects that might affect their serviceability. General tolerances for all dimensions are plus or minus 0.010 unless otherwise specified.

J476A_196106
The Dryseal American Standard Taper Pipe Thread, the Dryseal American Fuel Internal Straight Pipe Thread and the Dryseal American Intermediate Internal Straight Pipe Thread covered by this standard conform with the American Standard ASA-B2.2. The Dryseal SAE-Short Taper Pipe Thread in this standard conforms with the Dryseal American Standard Taper Pipe Thread except for the length of thread, which is shortened for increased clearance and economy of material. The significant feature of the Dryseal thread is controlled truncation at the crest and root to assure metal to metal contact coincident with or prior to flank contact. Contact at the crest and root prevents spiral leakage and insures pressure-tight joints without the use of a lubricant or sealer. Lubricants, if not functionally objectionable, may be used to minimize the possibility of galling in assembly.
