Perkins Engines Daily and Weekly Inspection

Daily Inspection of Perkins Engines

Lubricating Oil Level

With the engine stopped for at least 5 minutes:

i) Withdraw the dipstick and wipe clean.

ii) Re-insert the dipstick fully into the sump.

iii) Wait for at least 5 seconds, withdraw and check the oil level in relation to the two marks on the dipstick.

iv) Repeat operation (i)(ii) (iii) at least twice, until identical recordings are observed. If the oil level is below the top mark, add sufficient of the same grade as that already in the engine to bring the oil level up to the top mark. Always replace the filler plug immediately replenishment is completed.

Coolant Level

WARNING!! The cooling system is pressurized - do not remove the filler cap when the engine is hot. Hand protection must be worn.

With the engine stopped remove the radiator cap; the coolant should be 25 mm (1") below the top of the filler neck. If the level is low top up with a solution of water and inhibitor or water and anti-freeze similar to that already in the engine.

Leaks

Visually check the engine for fuel, oil, coolant and exhaust leaks, repairing where necessary.

Weekly

Deal with items under Daily Inspection.

Air Cleaner Restriction Indicator

The middle section of the restriction indicator 'A' will remain clear while the air cleaner is in a serviceable condition. When the filter reaches its contamination limit the restriction indicator will sense the change in manifold pressure and middle section 'A' will change to red, At this point the air filter must be changed. When the air filters have been changed reset the indicator by pressing button 'B'.

Battery

WARNING!! Hand protection must be worn when checking electrolyte level in the battery. Inflammable gas giving off by the battery. Do not check with a naked flame.

Remove the plugs or 'quick fill' covers and check the level of electrolyte. It should be approximately 3 mm above the top of the plates. If it is low, top up with pure distilled water. Replace the plugs and wipe the top of the battery clean and dry.

Radiator

If the engine is working in dirty or dusty conditions check that the air passages in the radiator are not becoming choked, They can be cleaned out by blowing compressed air in the direction opposite to that of the normal air flow.

Fenner Taper Lock Bushes Maintenance Instructions

Experience has shown that taper lock bushes as fitted in the fan pulleys and battery alternator driven pulleys can work loose shortly after being put into service. Check using a hexagon wrench to tighten screws (1) gradually and alternately until all are tightened to the required torque full details of taper lock pulley. Replace any guards removed before running the engine.

New Or Rebuilt Engines

It is essential to carry out the following maintenance procedure after the initial 100 hours.

Flanges And Fasteners

Check the torque on all external fasteners including the exhaust manifold and turbocharger flanges. Tighten all hose clips and pipe unions.

Turbochargers

If the engine has been overhauled and a filter joint fitted to the turbocharger oil feed, this should now be removed and replaced with the standard joint.

Engine Oil And Spin-on Filters, Also Centrifugal Oil Filter (Where Fitted)

Change engine oil and disposable filters clean centrifugal filter.

Draining the Water Trap/Sedimenter (Where Fitted)

There are no moving parts or elements to service, however daily open the drain plug to remove collected water and sediment. The plug is self retaining, unscrew until loose. Leave open until clean fuel is seen. Screw back in (see Fig. 21).

Engine Alternator Drive Belt

WARNING!! Disconnecting batteries or any other means of starting.

Remove the small mesh guard (1) around the alternator. The toothed belt used to drive the alternator replies on tooth engagement to transmit to load. It does not require preloading, however a slight initial tension to ensure that the belt fits snugly round the pulleys is desirable. Using light pressure midway between the two pulleys a total deflection of 1.5 mm is satisfactory (see Fig. 22). Refit the guard.

Diesel Generator Power Ratings: Standby vs Prime vs Continuous

Diesel generator sets are commonly used in a variety of sectors due to their dependable performance and high efficiency. They can be used for emergency power supply in the event of a power cut or used in places without connection to a power grid. When selecting a diesel generator for your home or business, you need to consider many factors, such as generator’s ratings. In this article, we’ll explain the three basic rating types - standby, prime, and continuous in diesel generators. ISO-8528-1:2018 defines basic generator set rating categories based on four operational categories: Emergency Standby Power (ESP), Prime Power (PRP), Continuous Power (COP) and Limited-Time Running Prime (LTP). Read on and learn the application of power ratings for engines used in generating sets. Standby Power Rating Standby Power(ESP) is used to supply emergency power when the external power supply is interrupted, such as power outages. Standby power rated generators can supply reliable electricity as t...

How to Choose a Household Mini Generator

With the improvement of people's living standards, there are more and more household appliances, such as rice cookers, microwaves, kettles, refrigerators, air - conditioners, washing machines, etc. It can be said that every household has them. But what if there is a power outage? These appliances won't work properly, and our lives will be greatly disrupted. How can we avoid this? We can use household mini - generators to provide convenience in power consumption. So, how to choose a good household mini - generator? Consider the noise level Since it is for household use, when choosing a household mini - generator, we need to check whether the noise will affect the neighbors. Generally, the seller will demonstrate the performance of the generator in advance. A good household generator can reduce noise by about 80%. Choose a generator with a moderate price Due to different brands, there are significant differences in power, and consequently, the price differences of househ...

How to Choose Efficient Diesel Generators for the Film and Television Industry?

In the film and television industry, the stability of the electricity supply during filming is crucial. Whether the equipment are the cameras or the lighting equipment on the filming site, or the post-production equipment, they all need stable and reliable power support. Unstable or interrupted power can result in interrupted filming, damage to equipment, and even affecting the progress and quality of the entire project. Therefore, investing in high-efficiency diesel generator sets has become an important measure for the film and television industry to ensure the reliable power supply for shooting. Determine the power requirements Before choosing a diesel generator set for the film and television industry, it’s necessary to figure out the total power needs, including the electricity demand of the shooting location, the total power of the electrical equipment and the time of using electricity. Also consider whether there are special needs for the generators such as low noise level and...
