Hanbury - Head Complaints} Grylls Esq. Rolls Royce Limited. Experimental Department. D E R B Y. Dear Mr.Grylls, The small pressings are pushed in the nipple threads to prevent dirt getting in during transit only. A screw driver is usually used to remove them and then fit a nipple. We do not do this because of the variety of nipples used. We do however have a nipple fitted during balancing and remove it to fit the tin cap. You will understand that the nipple once fitted is left in place permanently. Yours sincerely, J.A. Daniell | ||
