OBJECT OF TEST. TESTER. Tests on connecting rod big end bearings. A.{Mr Adams} C. Lovesey. CONDITIONS. Bench test. SUMMARY OF TEST. The bearings failed on the standard rods, and the mild steel rods white-metal lined after 13 hrs. running under similar conditions. These bearings look excellent after 22 hrs. running under similar conditions. A set of rods with mild steel bushes has been fitted to 8-EX for 10,000 miles test. Hs.{Lord Ernest Hives - Chair} | ||
