| -2- it is the usual weakness that two holding down bolts at the extreme ends allows the centre to bulge out, and where the load is required the cap is weak and collapses. In the case of the O.S. damper a .004" feeler can be inserted between the flange face of the cap and the face of the damper case. It is all a question of having just the required thickness of the cork packing and the rubber packing. If too much <del>as</del> the cap collapses as stated, E.{Mr Elliott - Chief Engineer} will understand this, as we have the same trouble at the bottom of the pivot pins on the front axle of the 25 HP. .004" CLEARANCE DAMPER GLAND. CLUTCH. The drivers are reporting that the clutch is on the verge of slipping. A light load on the pedal caused by the foot resting on same will set it slipping.
