OPERATING AND MAINTENANCE-C.3 I On stop start low mileage work, the hours run are more applicable than the mileage covered. the first 500/1000 miles (800/1600 km) or 25/50 hours in service. It is also recommended that the following procedure be adopted where an engine has been laid up for a considerable period before it is again put into service. With the engine thoroughly warmed through, this checkover should comprise the following points. 1. Drain lubricating oil sump. Renew lubricating oil filter element or canister. (Refer to Page L.5 or L.6) . 2. Remove the rocker assembly, check that the cylinder head nuts are to the correct torque. (Refer to Page B.2). 3.
Refit rocker assembly and set valve clearances. (Refer to Page B.8). 4. Refill lubricating oil sump with clean new oil to the correct level. (Do not overfill). 5. Check fan belt tension. (Refer to Page M.1). 6. Check coolant level in radiator, inspect for any coolant leaks. 7. Check security of all external nuts, setscrews, hose clips, mountings, etc. 8. Start engine and check for any fuel or lubricating oil leaks. 9. Carry out test to check general performance of engine. Thereafter routine maintenance should be in accord- ance with Periodical Attentions which are given on previous Page. Daily or every 8 hours Check coolant level. Check sump oil level.
Check oil pressure (where gauge is fitted). In extreme dust conditions, clean oil bath air cleaner and empty dust bowl on dry type air cleaner. Every 4,000 miles (6,000 km), 150 hours or 3 months t Drain and renew lubricating oil (see list of approved lubricating oils Appendix). t Renew lubricating oil filter element or canister. Clean oil bath air cleaner. Empty dust bowl on dry type air cleaner. 'Check drive belt tension. Clean water trap. Lubricate dynamo rear bush (where applicable). Every 12,000 miles (18,000 km) 450 hours or 12 months NOTE: If the cylinder head is removed for any reason e.g. top overhaul, then it is recommended that the cylinder head nuts are retorqued as shown in Fig.
E.23 after 500/1000 miles (800/1600 km) or 25/50 hours with the engine hot, to the setting given on Page B.2. It is assumed that electrical equipment will have already been checked for such points as dynamo rate of charge, effectiveness of connections and circuits, etc. t Renew final fuel filter element - agricultural and in- dustrial applications. Clean element of dry type air cleaner or renew (if not indicated earlier). Every 24,000 miles (36,000 km) or 900 hours Renew final fuel filter element - vehicle applications.
ProtecUon of an engine not in service miles (108,000 or hours The recommendations given below are to ensure that damage is prevented when an engine is removed from service for an extended period. Use these procedures immediately the engine is removed from service. The instructions for the use of POWERPART products are given on the outside of each container. 1. Thoroughly clean the outside of the engine. 2. Where a preservative fuel is to be used, drain the fuel system and fill with the preservative fuel. POWERPART lay-Up 1 can be added to the normal fuel to change it to a preservative fuel.
If preservative fuel is not used, the system can be Kept charged with normal fuel but this will have to be drained and discharged at the end of the period together with the fuel filter. 3. Run the engine until it is warm. Correct any fuel, lubricating oil or air leakage. Stop the engine and drain the lubricating oil sump. 4. Renew the lubricating oil filter canister. 5. Fill the sump to the tull mark on the dipstick with c,ean new lubricating oil or with a correct preservative fluid. POWERPART lay-Up 2 can be added to the lubricating oil to give protection against corrosion curing the period in storage.
If a preservative fluid is used, this must be drained and normal lubricating oil used when the engine is returned to service. Arrange for examination and service of proprietary equipment, i.e., compressor, exhauster, starter, dynamo etc. Service atomisers. Check and adjust valve clearance. t I Refrigeration unit engines have a larger capacity I sump and larger lubricating oil filter canister, therefore the lubricating oil and filter change can be extended to 1000 hours. Also with a primary fuel oil filter fitted, the main fuel filter element change period can be extended to 1000 hours. 'The drive belt tension should be checked monthly on engines rated above 3,000 rev/min.
POST DELIVERY CHECKOVER After a customer has taken delivery of his Perkins Diesel engine, it is advisable, in his own interest, that a general checkover of the engine be carried out after 4.108 Series Workshop Manual, June 1986
