How To Keep Your Turbocharger Chager Clean

The right maintenance and sensation will maximize service life and uptime as well as avoid costly failures

Past Jean-Marc Labelle, Professional Engineer at Tigercat

The turbocharger has been around for many years and has get an industry standard on most forestry machines.

The corporeality of exhaust on the hot side of the engine controls the speed of the turbo exhaust turbine. Equally the speed increases, a greater corporeality of air is forced into the engine and more horsepower is produced. A steel shaft mechanically links the turbine to the compressor bike and effectively controls the volume of air going into the cool side of the engine.

Turbocharger speeds reach well over 100,000 rpm. With faster rotational speeds, in that location is little room for error.

Proper maintenance and operating practices may forbid impairment or premature wear.

Air filtration and restriction

A turbocharger also relies on the cleanliness of the air intake system to piece of work efficiently.

Air filtration is the first line of defense for the turbo from dirty atmospheric air, as it prevents contaminants from coming into direct contact with the compressor inlet. The outside air enters the pre-cleaner then circulates through the primary (outer) filter element. And so information technology passes through the safety (inner) filter and finally toward the turbo inlet.

To keep this arrangement working efficiently, any droppings accumulated effectually the pre-cleaner must be removed every eight hours, or more often if working in challenging conditions. This will help keep the turbo vacuum pressure inside limits and lower the longitudinal strain on the shaft at high speeds, preserving the life of the seals and internal parts of the turbo. A plugged filter will cause the turbo speeds to increase as there is no load on the compressor. In plow, this can cause the turbo to neglect.

The air cleaner element should but exist replaced when indicated by the filter restriction indicator, as opposed to proactive replacement. Over-servicing may return the system less efficient, as it relies on some filter grit buildup to maximize the filtration capabilities.

It is not recommended to make clean the filter. There is a risk of contaminants reaching the make clean side of the filter, and a take chances of filter impairment from high force per unit area compressed air.

Any type of cleaning is only as good equally the people, methods, tools and inspections used in the process. The secondary (condom) element should never be cleaned, only replaced.

If you lot determine to make clean the filter, first exercise a visual inspection. If in that location is any harm to the filter body, gaskets or end plates, the filter should be discarded. E'er service the filter in a clean environment and repackage the filter immediately subsequently the cleaning procedure. Limit cleaning to a maximum of three intervals and always refer to the filter manufacturer'due south recommended cleaning practices to safely execute the chore. Some primal points to remember:

• Pressure should non exceed xxx psi when using air.
• Directly the air from the clean side pointing out.
• Do non allow the nozzle to contact the filter media.

Keep the filter replacement procedure cursory to forbid any contaminants from entering the intake system. A clean rag may be used temporarily to block the intake port, but it is crucial that information technology is removed before reassembly.

The finest of dust, sand and dirt particles may have a astringent impact on the turbocharger, causing pitting, scoring or even total fracture of the compressor bike fins that could result in catastrophic failure.

Turbochargers are finely counterbalanced.The smallest of cracks to the associates can unbalance the system and accelerate failures.

Cooling and lubrication

A warm up is important before exercising and information technology would merely make sense to at more than 100,000 rpm.

Turning off the engine right after working the automobile difficult ways the lubricating oil menstruum by the pump will exist turned off while the turbo is still spinning at loftier rpm for several minutes.

With no oil, there is no way to speedily remove the heat. This can crusade premature wear to the shaft, bearings and seals and shorten the life of the turbo. The same can happen past not allowing plenty time for the oil to warm on startup. Cold oil moves more slowly, delivering inadequate lubrication to the bearing.

Every bit mentioned, proper maintenance procedures will assist extend the life of the turbocharger.

Quality oil

The tolerances inside the rotating parts of the turbo are very pocket-size and rely on good quality oil to keep all parts moving flawlessly.

Ever remember to replace the oil at the recommended service intervals or even sooner if there is a risk of contamination.

Dirty engine oil tin can quickly reduce overall life equally it permanently scores the bearings and shaft.

These imperfections in the surface of the material then leave room for further contaminants to settle and accelerate wear on the parts. A rough surface besides restricts oil flow throughout the turbocharger and its ability to remove heat.

Crankcase ventilation

During the combustion process of the engine, there are vapours that escape past the piston rings into the engine crankcase and mix with oil vapours.

To prevent over-pressuring the sump, these vapours are filtered from the oil and returned to the turbo inlet pipe, while returning the condensed oil to the sump.

On Tigercat FPT 6.seven and four.5 litre engines, the CCV upper case filter is located direct above the engine flywheel housing and is specifically designed to match the engine.

For this reason, just Tigercat branded filters should be used. A filter that looks the same does non necessarily hateful it is the aforementioned. CCV filters have a specific oil separation media to command blow-by gasses and have been designed and manufactured specifically for the application with proprietary materials to piece of work in unison with the rest of the system. Filters with specifications unfit for the applications can have a negative touch on on the overall functioning. Some of these include blow-by gas period rate, crankcase pressures, filter porosity and reduced service life.

Oil at the turbocharger

Seeing some oil at the turbo is normal. The combustion vapours directed to the intake can be mixed with some residue oil that is usually burned during engine combustion.

Some of this oil may settle in the pipe just before the turbo inlet and as such, information technology is normal to see oil in small quantities.

What is important to remember is to replace the CCV filter at the recommended service interval. This often-neglected filter plays an important role.

Incorrectly servicing this component tin can result in filter saturation and allow oil to build upward at the turbo compressor inlet and outlet.

This reduces engine performance and turbo boost pressure, due to the restriction on the compressor wheel acquired past coking and may negatively affect components downstream of the turbo exhaust.

Left too long, this may pb to turbocharger failure or even engine failure.

Turbocharger tricks

Only as monitoring the fuel, engine speed and oil gauges is second nature when driving your motorcar, keeping an eye on the auto'southward boost force per unit area can assist grab any business concern in the early stages. Should the boost pressure appear to exist low or drib suddenly, the operator should be proactive and investigate accordingly.

Since information technology is easily accessible and fastened with only four bolts, the turbo is often replaced prematurely in a low heave pressure level event.

Some factors to review and consider beforehand are loose or worn charge air connections, restricted air filters, blocked precleaners, saturated CCV filters and worn gaskets between the turbo and intake/exhaust manifold.

Cycle pause

In an event where the shaft or compressor wheel breaks, the turbo boost pressure level will subtract significantly. At this time, stopping the engine immediately is crucial as continuous operation tin allow a large amount of oil to reach the engine intake and enter the cylinder chambers. The meaning amount of power generated from the oil mixing with the fuel and the air during the combustion process can cause severe damage and has the potential to bend the connecting rods resulting in an engine replacement.

The oil may contaminate exhaust catalysts, leading to extensive repairs.

Instruction is the primal to success. Make sure that anybody on the crew knows how and why the system works. It may positively influence and motivate the team to utilize best operating practices, perform correct maintenance procedures at the required intervals and to have an awareness of potential issues.

This will get a long way in keeping the engine and turbocharger organisation working flawlessly.
