Tigercat Fuel Filters

Protect your engine with high performance Tigercat synthetic media fuel filters.

In BTB #41 November 2015, Dealing with Diesel, we covered important issues surrounding diesel filtration and fuel quality and why both are critical to peak performance and reliability in modern diesel engines.

To summarize, the latest generation high pressure common rail (HPCR) fuel injection system used with the Tigercat FPT engine operates at much higher temperatures and pressures than previous engines. This means even slight fuel contamination can cause serious engine damage. To keep Tigercat FPT engines running smoothly, it is critical to use fuel filters that meet Tigercat specifications such as the BH810 main fuel filter and to replace filters at the correct intervals as specified in the operator’s manual.

The BH810 primary fuel filter is placed after the transparent water/fuel separator filter on Tigercat FPT engines and is the last line of defence for the engine before the diesel enters the fuel injection system. The specially engineered synthetic filter media traps particles down to four microns (a human hair is approximately 100 microns in diameter) and is certified for use with Tigercat FPT engines. The filter will hold up to 99.9% of contaminants over four microns even in conditions of high vibration and fuel surges characteristic of forestry and off road industrial applications. This improves the reliability of the engine fuel system and reduces downtime and maintenance costs.

Competing filter media made from cellulose with glass or polyester additives are just not up to the job. Cellulose can absorb water leading to microbe growth and premature filter plugging. Even worse, water-logged filters can freeze in cold weather and reduce fuel flow. Ultimately the result can be a collapsed filter allowing unfiltered and potentially contaminated fuel to enter the injectors. The fuel injectors then quickly become damaged, requiring expensive repair.

In addition to using the correct filter, it must be changed at the right time. The operator’s manual specifies the proper intervals for changing filters. These intervals have been determined to be acceptable under normal operating conditions. However, if you suspect the diesel fuel in your area is of lower quality, you may need to change your filter more often. Consider using a two-stage filtration system on diesel storage tanks and mobile fuelling carts to ensure the fuel is as free of contaminants as possible before it enters the machine tank. As an extra preventative measure, always clean the fuel filler neck before filling to ensure debris does not enter the tank. Consult with your authorized Tigercat dealer immediately if you suspect a problem with fuel quality. Use genuine Tigercat parts to protect your investment.
