LUBRICATION SYSTEM-LA L9 1. Outlet to Main Oil Filter 2. Relief Valve Plunger 3. Plunger Spring 4. Spring Cap 5. Retaining Splitpin L7 NOTE: The relevant clearances for these dimen- sional checks are given on Page B.10, they are the clearances applicable to a new pump and are in- tended to be used as a guide. Should a lubricating oil pump be worn to such an extent that it ad- versely effects the working oil pressure, then a re- placement pump should be obtained. 2. Insert the drive shaft complete with inner rotor into the pump body. 3. Replace the end cover assembly and fit the four securing setscrews. Ensure correct positioning so that the suction and delivery pipes will locate correctly.
To Re-Assemble the Oil Pump 4. Press the oil pump drive gear onto the shaft. 1. Insert the outer rotor ensuring that the face which carries the chamfered edge enters the pump body first. (Refer Fig. L.5). 5. Finally rotate the pump by hand to ensure that it turns quite freely. To Rem the Oil 1. Prime the lubricating oil pump with clean lubricating oil. 2. Refit the suction and delivery pipes, do not tighten the pipes at this stage. 3. Place the lubricating oil pump assembly in position, locate with the securing screw and lock it with the tab washer. 4. Tighten the delivery pipe at both ends, refit the setscrew securing the suction pipe assembly. 5.
Tighten the suction pipe at the pump end then refit the strainer on the end of the suction pipe. NOTE: The strainer which fits on the end of the suction pipe should be thoroughly cleaned in a suit- able cleaning fluid before being refitted. It is good practice to remove this strainer and clean it thoroughly on every occasion when the sump is removed. 6. Replace the sump as previously detailed and secure with the setscrews. 7. Fill the sump to the correct level with clean oil of an approved grade. L8
