CYLINDER LINERS OIL PAN The cylinder block uses replaceable wet cylinder sleeves. The lower end of each sleeve is sealed against the block with three elastomer rings. The upper end is sealed with a ring of EPDM elastomer situated directly under the sleeve collar. This design cools the upper section of the sleeve better because the area of coolant circulation is larger. The oil pan is plastic or steel with a threaded plug for draining. The plastic pan has a groove in the mounting flange which accepts a molded elastomer gasket for a seal. The steel pan is sealed with a gasket on the oil pan flange. Twenty-two spring-loaded screws clamp the pan to the block.
12 The lower seals are fitted in grooves in the cylinder block. The bottom seal is of a different material and fluorescent violet in color to distinguish it from the intermediate seals. 11 Figure 12 — Oil Pan and Stiffener Plate The oil pan includes an oil level/temperature sensor with connector. The filler tube and dipstick mounting ports are also components of the oil pan. Figure 11 — Cylinder Liner and Seals Oil pans with the sump at the front or at the rear are available to accommodate axle forward or axle back chassis. Page 20 DESCRIPTION AND OPERATION 1.
