| -2- To overcome this, we allow generous sized drain holes in the casing between gland and bearing. A water flinger on the shaft would provide an extra guard against water contact with bearing. The material of our gland ring is "Celeron", but "The Morgan Crucible Co" could supply a suitable grade of carbon ring if you desired that material. The rubber ring which we are sending is in the material carrying the trade name of "Duprene". Yours faithfully, for VAUXHALL MOTORS LIMITED. [Signature] A.W. LARKING. Asst. Power Unit Engineer. | ||
