Fig. 1, Camshaft Bracket Bushing Lubrication
Use an NLGI Grade 1 or Grade 2 multipurpose chassis grease. If grease leaks out from under the cam head, the camshaft bracket grease seal is worn or damaged. For grease seal replacement instructions, see of the Recreational Vehicle Chassis Workshop Manual, or take the vehicle to an authorized Freightliner dealer.
Camshaft brackets without grease fittings are fitted with special seals and packed with extended-lubrication-interval chassis grease. Grease them only when the camshaft is disassembled for servicing.
