General.
1. Lubrication.
All moving parts of the MG 5061A are lubricated by the oil within the sump as it travels throughout the hydraulic system. The preventive maintenance required to keep the transmission functioning properly is slight; however, it is very important that the following directions be complied with. No other lubrication is required beyond the daily oil check.2. Overhaul interval.
A complete overhaul of the unit should be made at the same time that the engine is overhauled. All parts showing signs of wear, fatigue, etc. should be replaced at that time.Hydraulic System.
1. Oil capacity.
The oil capacity of the model MG 5061A Marine transmission is 0,81 US Gallons (3,05 liters) or to the 'FULL' mark on the oil level gauge. The oil used in the marine transmission should be of the same quality and type recommended by the engine manufacturer for use in the engine (see section 2, Table 1).2. Oil level.
The oil level should be checked daily. To check oil level, start engine and with gear in neutral, check level immediately and adjust oil level between the full and low mark. The check should be performed with the oil at ambient temperature as it expands in volume when hot. Experience will show the operator the correct oil level to read on the gauge when checking the level at operating temperature.3. Oil change interval.
The oil must be changed every 1000 hours of operation or more often if conditions warrant. Boats that are placed in dry dock or storage for periods of three months or more, should have the oil changed in the marine transmission prior to return to active use.4. Draining.
Drain the transmission by removing the plug on the rear side at the bottom. See figure 2-3.5. Filling.
a. Remove the filler plug (see figure 2-3) from the top of the main housing assembly.b. Pour the oil through the filler opening.c. Fill the sump with 0,81 US gallons of the proper weight and type of oil. See section 2.d. Start the engine and let it idle with transmission in neutral. Check oil level immediately and add oil as necessary to bring the level to a point between the 'Low' and 'Full' marks on the oil level gauge. Replace the plug securely.6. Oil screen filter (see figure 2-3).
Remove and clean the oil strainer at every oil change or sooner if necessary.Periodic Visual Inspection.
1. Check the mountings for tightness or damage such as cracks. Tighten loose mountings and replace damaged parts.2. Inspect heat exchanger oil lines for leaky connections, kinks, cracks or other damage. Replace damaged lines.3. Check pressure and temperature gauges where applicable.4. Inspect the drive line and the input and output shaft oil seals for leakage. Replace parts as required.5. Inspect unit nameplates for looseness and corrosion. Tighten mounting screws that are loose and replace nameplates that are corroded. Zinc anodes are installed in the heat exchanger to help protect it from corrosion. Remove and inspect the anodes frequently because they are consumed as they provide protection. Replace the anodes as
