Chapter 4 35943 Schedules The schedules which follow must be applied at the interval (hours or months) which occur first. First service at 25/50 hours Every 1000 hours Every day or every 8 hours Every 2000 hours Every 500 hours or 12 months F...
35943 Chapter 4 How to drain the coolant circuit Warnings! • Do not drain the coolant while the engine is still hot and the system is under pressure because dangerous hot coolant can be discharged. • Discard used coolant in a safe place and in accordance with local regulations.
Chapter 4 35943 How to check the specific gravity of the coolant For mixtures which contain inhibited ethylene glycol: 1. Operate the engine until it is warm enough to open the thermostat. Continue to run the engine until the coolant has circulated through the cooling system.
35943 Chapter 4 How to drain the raw water system Caution:The raw water system cannot be drained completely. If the system is drained for engine preservation purposes or for protection from frost, the system must be filled again with an approved coolant mixture.
Chapter 4 35943 How to clean the strainer for the raw water pump The strainer for the raw water pump is fitted in the outlet hose for the raw water pump. The purpose of the strainer is to protect the engine heat exchanger from debris.
35943 Chapter 4 How to check the impeller of the raw water pump 1. Ensure that the seacock is closed. 2. Release the six setscrews (A1 page 17) which fasten the end plate of the raw water pump and remove the plate.
How to adjust the belt tension Cautions: • The alternator is driven by a drive belt of a specific design. Use only a Perkins POWERPART drive belt. If this is not done, an early failure of the belt may occur.
Warning! Discard the used element and fuel in a safe place and in accordance with local regulations. Caution: It is important that only the genuine Perkins parts are used. The use of wrong parts could damage the fuel injection equipment.
Chapter 4 35943 How to renew an atomiser Cautions: • A new clamp (A5) must be used every time an atomiser is fitted to the engine. • Do not allow dirt to enter the fuel system. Before a connection is disconnected, clean thoroughly the area around the connection.
35943 Chapter 4 How to eliminate air from the fuel system Caution: When air is to be eliminated from the fuel system, only use the starter motor to start the engine after air has been eliminated from the low-pressure side of the fuel system.
Chapter 4 35943 How to renew the lubricating oil Warning! Discard the used lubricating oil in a safe place and in accordance with local regulations. Note: Renew the filter canister when the lubricating oil is renewed. 1. Connect a suitable hose to the outlet of the sump drain pump (A1).
• Do not fill the sump past the notch (B2 page 24) on the dipstick. • The canister contains a valve and special tube to ensure that lubricating oil does not drain from the filter. Therefore, ensure that the correct Perkins POWERPART canister is used. Page 25...
Chapter 4 35943 How to renew the engine breather assembly Cautions: • It is important that the area around the vent hole (A3) is kept clean and the vent hole is not restricted. • Ensure that the pipe (A1) does not contact other components as this may cause the failure of the pipe.
35943 Chapter 4 How to renew the element of the air filter 1. Release the hose clip (A1) and remove the air filter assembly. 2. Remove the filter element (B2) from inside the filter assembly (B1). 3. Fit a new filter element and fit the filter assembly to the engine.
Chapter 4 35943 How to set the valve tip clearances Notes: • The valve tip clearance is checked with a feeler gauge between the top of the valve stem and the rocker lever (A), with the engine cold. The correct clearance for both the inlet and the exhaust valves is 0,35 mm (0.014 in).
Specialist manufacturers will advise on the maintenance of these anodes. Supplementary tools A general tool kit and an on-board spares kit are available from your Perkins Distributor. It is recommended that the tools and other parts, listed below, are also retained on-board:...
