MAINTENANCE

Regular maintenance is absolutely imperative if you want a diesel engine to last, and every diesel owner will probably encounter some pitfalls and problems. Although diesel engines require no ignition tune-ups and tend to last longer without major repairs than gasoline engines, they do require regular low-cost maintenance, mostly in the form of frequent oil and filter changes. 

      INJECTORS

 

Fuel injectors that are clean and functioning properly are a key element to getting the best performance and fuel mileage from your diesel engine . Properly functioning fuel injectors will inject the fuel in an optimal atomized-mist that burns cleanly and gets the most out of the fuel.

​

Over time, deposits build up in the tips of fuel injectors, typically when there's fuel left in the injector tips after the engine is shut down, which cooks and turns into deposits that affect the nice, clean spray of the injector.

​

We have specialised equipment to remove any build up from the internal and exterior of your injectors and supply new components to replace any that were damaged by the build up

​

Here is a step by step list of what we do to every injector:

  • All injectors are stripped of removable parts (o-rings, filters, pintle caps etc)

  • The body is cleaned thoroughly and any paint removed

  • Injectors are ohms tested to ensure the coil/solenoid is operating at the correct resistance

  • Injectors are ultrasonically cleaned, they are pulsed and backflushed during this process

  • Spray pattern is tested to ensure all injectors are atomising fuel correctly

  • The volume of fuel flowing from each injector is accurately measured. Injectors must be within 2% of the correct flow rate to be passed

  • Injectors are then leak tested to make sure the pintle is seated properly and no fuel seeps from the tip

      DIESEL PUMPS
 

To reduce issues with diesel engines we recommend you follow these points:

​

  • Clean Air : Dust free air is very important for the diesel or any engine. It is advised to clean and replace air filters periodically as recommended by the engine manufacturer.

  • Pure Oil : Similarly oil is very important. It is like blood in human body. Changing oil filters and changing oil periodically as recommended by the engine manufacturer is very very important.

  • Pure Diesel : Clean Diesel free from impurities and adulteration is essential and must for the fuel pump. Changing diesel filters periodically is very important in ensuring clean supply of diesel to the fuel injection pump and injectors.To prolong the life of a diesel engine, follow these tips.

 

ENGINE AND TRANSMISSION WARM-UP RECOMMENDATIONS

 

Allow the engine to warm-up for a minimum of five minutes before applying a load.

  • If loads are applied to the engine without proper warm-up, engine seizures, failures or premature wear may develop.

  • Also, warm-up the transmission oils when operating the machine in cold temperatures.

  • Cold temperatures increase the oils viscosity. This can cause delayed oil circulation or create abnormally low hydraulic pressures.

  • To warm-up the hydraulic oils, run the engine at about 50 percent of the rated engine rpm (see chart).
