Continued:- The effect of this modification is to produce an immediate increase in the frictional load for a given spring pressure, and, what is more important, the friction remains more consistent with running. The only objection seems to be the possibility that the clamping bolts may distort the socket and tighten up the sleeve G.100433. Actually, on two cars which we have tried, this does not occur, but it may be advisable to increase the initial clearance on the outer diameter to make sure of it. If you agree to the foregoing, we will issue a Depot Sheet for use in cases of complaint. We find that a load of 9 to 10 lbs. is desirable on the Bentley cross steering tube to suit many Owners, and this load is easily obtainable without overstressing the springs. The alteration would also cheapen the cost of Production as the counterboring referred to above makes a good oil reservoir and would avoid the necessity for machining a separate oil groove and reservoir in each contact piece; also, the sleeve G.100433 and contact piece G.100441 could be made in one piece.
