Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/MJ.18.11.31. (X403) FILTERS FOR BIJUR LUBRICATION SYSTEM. We are very dissatisfied with the filters used in the Bijur drip plugs, and also to protect our pivots. When these filters are thoroughly saturated with oil they become a pasty mess and seem most reluctant to allow any oil to pass. We should like information from the manufacturers of cloth filters as to the various woven types of filters they can supply, with a view to trying these out in place of the felt filters. We should start by testing them out on the large filters protecting the pivot pins on the front axle. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
