HOSE 5353596 - Caterpillar

If the engines are regularly cold started, Caterpillar recommends that the plastic 9M0853 Plunger in the oil filter relief valve in the filter base be replaced with the steel 1P1367 Plunger.
As an additional precaution, all of the 3500 Family of Diesel Engines now use the 2P4005 Oil Filter Element instead of the 1R0716 Oil Filter Element. The 2P4005 Element has a metal center tube. In the unlikely event of a filter collapse, the metal center tube tends to generate less debris that could contaminate the lube system. It is recommended that 2P4005 Oil Filter Elements be used on all of the 3500 Family of Diesel Engines in place of the 1R0716 Oil Filter Element until further notice. The 1R0716 Oil Filter Elements should continue to be used in all other applications. The 2P4005 Oil Filter Element went into effect in the 3500 Family of Diesel Engines as listed in Chart B.
