« on: 30 Nov 2009 at 17:51 »
hi all,  question.   my 1948 t35s steering headstock does'nt have any end float, but is very, very free to move. Can anyone tell me please, What is the torque or loading permissible on the headstock bearing adjuster ring ?.  alternatively, is any kind of damper permissible and possible to fit?? denis. S.

Denis,
           The original Mk1 T35's had a cup and cone lower headstock bearing (5/16" balls) and a top bearing that can best be described as a deep tracked thrust race (3/16" balls) - the top and bottom tracks being identical.
          Later Mk3's had a taper roller bottom bearing and a cup and cone top bearing (again 3/16" balls) that fitted below the top bridge plate (yoke).
         Mk4's and 5's had the same set up but the top bearing cone was modified to have a spigot that fitted into an enlarged hole in the bridge plate.
       Now, it is possible to fit any combination of these bearings to any model of the T35 - providing the adjusting collar is also changed. In all cases, the bearings should be adjusted to eliminate any play without creating excessive preload. There is no mention in the 'Maintenance Manual' regarding torque figures for the steering head bearings or any of the other fixings, etc.
       Although a steering damper was listed as an optional extra, the T35 was renowned for it's good handling without a damper. If you are having trouble with the roadholding, check the wheel alignment. Also check that the front wheel spindle nut is tightened on the spindle (on some machines, it was necessary to fit a spacer washer - about 1/16" thick - between the end of the hub and the nut). If the nut is only clamped in the leading link but not pinching up on the hub, the front wheel can be rocked sideways as the nut is free to turn on the spindle.

                       Regards,
                              Eddie.
