Clutch Trunion Bearing B.III B.50 etc. The trunion housing GB.4084 is made in S/M, requiring dies. We suggest making it in 1/C. This would necessitate strengthening the jaws for the universal ring, in order to avoid risk of breakage when fitting the split pins. Rm{William Robotham - Chief Engineer}/NRC.{N. R. Chandler} | ||
