Ltd., recently paid us a brief visit for the purpose of discussing the double row sealed Skefko bearing as used on our original form of B.60 and B.80 water pump. He agreed that the non-ventilated type of bearings was totally unreliable, but stated that up to the present they had not reached the limit of the ventilated bearing in practical application and he considered that it would be quite able to cope with the 16 HP. absorbed by our fans. We should be very glad, therefore, if you would look into the question of modifying an existing B.80 pump to take a Morgan-Stuart gland assembly similar to that used on SOD.1398 in conjunction with the sealed Skefco ventilated bearing. Ventilation should be arranged on a principal similar to that employed by Vauxhalls and instead of a carbon sealing ring we suggest that Bakelite be used, the locking principal being similar to that on the Vauxhall 25 water pump.
