Bailey - Chief Engineer} Rm.{William Robotham - Chief Engineer} GWH{George W. Hancock - Head Chateauroux}3/R.18.11.36. 3 1/2 & 4 1/4-Litre Bentley Push Rods. Complaints of noisy tappets are in many cases found to be due to the permanent bending of the push rods. It appears to be a growing trouble. There are also cases of bad wear which has taken place on the bottom pad of the push rods. A large pip is formed corresponding to the hole drilled in the tappet cup. GWH.{George W.
