PROCEDURE FOR CHECKING OIL LEVEL The gearbox oil level should always be checked with the engine running at idle speed. FILLING Stop the engine. Fill gearbox to "full" mark on the dipstick with API "SD" engine lub oil. OIL CAPACITY: 4.8 U.S. Quarts (4.55 Litres) 4.8 U.S. Quarts (4.55 Litres) OIL PRESSURE Normal pressure is 300-320 psi (21.1 - 22.5 kgf/cm2) at 1,800 rpm and 1800F (830C). Minimum pressure is 270 psi (18.98 kgf/cm2) at cruising speed. PARAGON GEARBOXES Procedure for Checking Fluid Level - When the engine is first started, allow it to idle for a few moments. Stop the engine and check the transmission fluid level. Add type "A" transmission fluid, if necessary, to bring the level up to the mark on the transmission dipstick. Oil Pressure - Normal pressure is 60 psi (4.22 kgf/cm2) at normal operating temperature. PROPELLER SHAFT TRAILING (FREE WHEELING) Borg Warner have determined through practical experience that sail boats having Borg Warner transmissions (auxiliary engine installations) can sail with the propeller trailing (free wheeling) at unlimited speeds without risking damage to the transmission, providing the unit is filled with fluid (to full mark on dipstick). Twin engine power boats having one engine inoperative (shut down) with its propeller free-wheeling are also no longer restricted to a maximum speed or rpm, providing the fluid level is maintained at the full mark on the dipstick. CHECKING VALVE TIP CLEARANCES When rotating engines, they should always be turned in their normal direction of rotation, i.e., anti-clockwise when viewing from the gearbox end. The exception is contra-rotating engines, which is clockwise from the gearbox end. 4.108, 4.154 and 4.236 Engines The clearance is set between the top of the valve stem rocker and arm and should be 0.012 in. (0.30 mm) cold. Refer to Fig. 14 (a). When setting valve clearances the following procedure should be adopted: 1. With the valves rocking on No. 4 cylinder (i.e., the period between the opening of the intake valve and the closing of the exhaust valve), set the valve clearances on No. 1 cylinder. 2. With the valves rocking on No. 2 cylinder, set the valve clearances on No. 3 cylinder. 3. With the valves rocking on No. 1 cylinder, set the valve clearances on No. 4 cylinder. 4. With the valves rocking on No. 3 cylinder, set the valve clearances on No. 2 cylinder. 6.354, T6.354 MGT, T6.354 and HT6.354 Engines The clearance is set between the top of the valve stem and rocker arm and should be 0.012 in. (0.30 mm) cold. Refer to Fig. 14 (a) When setting valve clearances the following procedure should be adopted. 1. With the valves rocking on No. 6 cylinder (i.e., the period between the opening of the intake valve and the closing of the exhaust valve), set the valve clearances on No .1 cylinder. 2. With the valves rocking on No. 2 cylinder, set the valve clearances on No. 5 cylinder 3. With the valves rocking on No. 4 cylinder, set the valve clearances on No. 3 cylinder. 4. With the valves rocking on No. 1 cylinder, set the valve clearances on No. 6 cylinder. 5. With the valves rocking on No. 5 cylinder, set the valve clearances on No. 2 cylinder. 6. With the valves rocking on No. 3 cylinder, set the valve clearances on No. 4 cylinder. -61-
