HARDY ESQ. Referring to your order No.83947 for Steering Rollers, it will assist us in manufacture to keep the profile of F.89832 and F.89831 identical. To obtain this it is necessary to increase the centre groove diameter from 1.332 to 1.338. We shall be glad of your confirmation that this small modification is permissible. This will not apply to the first three bearings covered by your letter of January 4th. Yours faithfully, THE HOFFMANN MANUFACTURING CO., LTD. | ||
