I have had a talk with Sr. re bearings etc. The position at the moment is, they have five cars in the Depot, all with bearing trouble, and he anticipates a number on the road that is at a mileage of bearings failure. He therefore requires quickly a reliable Hall's bearing for the con roads, so that he can get a stock in ready for these cars. He agrees that white metal has given very little trouble in the main bearings and is in agreement with your memo. We are going to discuss the pros and cons of 30 HP and Phantom III tomorrow. 6-B-IV. I have tried this car, and the fitting of the balance weight to the flywheel has cut out the roughness reported at 1500 to 2500. We are going to examine the bearings and get the measurements of wear. The rear springs are the thick leaf type and the ride in my opinion is too jolty, for road holding etc. it is good. Brakes. The anti-judder device on the front brake anchorage does not stop brake thumps. They are thumping very bad, considerable wear has taken place in the pins of the anti-jaggering mechanism also on the fulcrum pin. The O.S. front brake drum is very badly ridged. The grooves are deep and would not allow for regrinding, the N.S. is bad but not so deep. If the car is going to continue running over here 2 new front brake drums will be required and new linings.
