Because Perkins builds engines with different cylinder sleeve designs, we recommend that anyone working on Perkins engines should refer to the specific engine manual to avoid problems. We supply official Perkins Workshop Manuals with our Foley Engines Parts Kits free of charge. They are also available for purchase separately.

Sleeve Designs

• Flangeless (stove pipe)
• Flange type (chrome) thin wall, narrow flange (early type .040/.045)
• Flange type (chrome) thin wall, narrow flange (late type .043/.045)
• Flange type (chrome) thick wall, wide flange .144/.146
• Flange type (cast iron) thick wall, wide flange .144/.146

Caution - Anyone servicing a Perkins diesel should order sleeves by serial number. Because of the wide variety of sleeves, only genuine Perkins sleeves should be used. Finally because of the high degree of rebuildability of these engines, the engine rebuilder should check the existing sleeve now in the engine to determine if it conforms to the serial number. Your Foley Engines Customer Service rep will make every effort to ensure that you receive the correct set of sleeves but can only work with your information.

Caution - Selection of Piston Rings: chrome plated piston rings must not be used on chrome plated sleeves. Chrome on chrome is not compatible and seizure will result. Ring sets of plain cast iron are available for such applications. To determine if the engine was originally equipped with chrome sleeves, check for the letter "C" adjacent to the engine number.

Additionally - Gasket selection: sleeve flange location on many Perkins engines is below the top surface of the block (refer to specific engine manual), other Perkins engine sleeve flange locations are based on height of the "firewall" protrusion on the top side of the flange in relation to the top of the block. In securing head gaskets, it is recommended that you select the correct gasket for sealing against the flange. This is particularly important where flanges are below the top block.

Finally - Foley supplies oversize sleeves for the model 4236 engine for those with worn parent bores. We also have oversize (.030) pistons for 4108 engine owners who do not want to tear down their engines and remove the old sleeves. These oversize pistons should be of particular interest to marine engine owners.
