Oil Filters The lubricating oil filter installed on most Perkins marine engines is the screw-on canister type. The canister is secured to the filter head by a threaded adaptor. Perkins diesel engines require the use of high quality lube oil filters made to Perkins original equipment standards. To protect our customers from filters that do not meet Perkins specifications, we have established minimum performance standards based on SAE oil filter test procedures SAE J806a. The Perkins Farmington Engineering Department maintains a list of filter manufacturers who have supplied test data to SAE J806a and have met Perkins minimum standards. These standards in general preclude the use of low quality, low cost filters. Renewing Oil Filter 1. Clean exterior of filter. 2. Unscrew and discard the oil canister. 3. Clean the filter head and threaded spigot. 4. Pour (slowly) clean engine lub oil into the center of the replacement canister until full'. 5. Using clean engine lub oil, lightly oil the top seal of the replacement canister. 6. Screw replacement canister onto filter head until the seal just touches head and then tighten by hand a further half turn. If the canister is overtightened, difficulty may be experienced in removal. 7. Run the engine and check for leaks. Do not run the engine at high idle until oil pressure has built up. Recheck oil level and top up as necessary. *It is recommended that before installing a new screw-on filter canister, it should be primed with oil. Clean lubricating oil should be poured slowly in the center threaded orifice, allowing time for the oil to fill the canister through the filter medium. When attaching a canister to a filter head not in the straight-up position, a small quantity of oil in the stack pipe may be spilled before the canister is screwed home onto its seal. RECOMMENDED ENGINE LUBRICANTS The recommended engine lubricating oil for naturally aspirated Perkins marine engines is a reputable brand of oil meeting the minimum requirements of U.S. Military Specification MIL-L-46152 when a fuel having a maximum sulfur content of 1.3% by weight is used. This was formerly known as MIL-L-2104B and can be identified by API Service Classification "CC" Lubricating oil for turbocharged engines should meet the requirements of MIL-L-2104C. which can be identified by API Service Classification "CD". Should questions arise concerning a particular brand of lub oil, consult the supplier. Synthetic Lubricating Oils As the result of continuing requests for Perkins approval of synthetic lubricating oils, the following policy is announced: 1. General Policy Perkins Engines does NOT recommend the use of synthetic lubricating oil for the following reasons: a. General experience to date shows the potential for excessive engine wear, particularly with reference to piston rings, cams and gears. b. Experience to date shows the potential for premature seal and other elastomer deterioration. c. Synthetic oils have been found to be subject to critical quality control requirements. Critical compounding is required and small deviations result in greater than expected performance variations. d. No major name brands currently have acceptable compounds. The other than name brand suppliers are difficult to identify and evaluate as dependable suppliers. -57-
