Steering ------------------------------------- We are now receiving chassis on test fitted with new type Friction Device. Our experience is that with the total amount of friction i.e. 3 stages, that the steering is unduly stiff and heavy. This experience has been confirmed previously on one or two special chassis which have been so fitted, and although we have taken special pains to see that the friction plates were of reasonable finish, we have finally had to reduce the friction to 2 stages. I consider it will be advisable to build up axles on all new chassis with 2 stages of friction only. Mrx. [signature] | ||
