The Air Filter
The TRX 2.5 air filter is carefully designed to deliver maximum
performance while protecting your engine from dust and dirt.
Use only the supplied filter. You will not improve engine
performance by switching to an aftermarket filter, and you
may risk engine damage due to poor filtration.
The TRX 2.5 air filter assembly consists of 3 pieces:
1. A rubber filter base
2. A plastic housing consisting of a permanently assembled
mesh cap and body
3. An oiled foam element
You must clean the filter after every hour of runtime, even if the
filter looks clean. Dust (which is often too fine to see) and dirt
constantly move through the filter anytime the engine is
running. Even if you can't see dirt on the filter, it is present inside
the foam after any amount of runtime. If you exceed the
recommended cleaning intervals, your engine will be damaged.
Engine damage or wear due to dirt ingestion is easy to detect,
and one of the top causes of premature engine failure.
Air Filter Cleaning Instructions
1. Remove the air filter from the
carburetor bore by pulling
the entire filter firmly to the
side to release it.
Do not pull straight up
2. Disassemble the filter. Pull the
rubber base out of the filter
body.With the base removed, the foam element is visible in
the bottom of the filter body. Pull out the foam element.
3. Clean the filter parts by thoroughly washing all three pieces of
the filter assembly in hot soapy water (dishwashing detergent
works well). Repeat twice.
4. Thoroughly dry the parts with a clean towel or compressed air.
Remember to wear your safety glasses when working with
compressed air.
5. Oil the foam element by saturating it with foam filter oil. Use
the supplied Traxxas filter oil (part# 5263) or a high-quality,
special-purpose foam filter oil like what is used for high-
performance motorcycle and ATV engines.This type of filter oil
is available at motorcycle pro-shops. If foam filter oil is not
available, clean 30-40 weight motor oil can be substituted, but
is not preferred. Never run the engine without a properly
oiled filter! Apply 30 drops of the Traxxas filter oil evenly to
the top, bottom and sides of the filter element (30 total drops
divided among the 3 surfaces). Squeeze the filter element
repeatedly to help spread the oil throughout. Squeeze the
excess oil from the foam.The filter element should be evenly
colored by the oil. Even color indicates that the oil is evenly
distributed. Note: Do not use the air filter oil for anything
other than the air filter. It is not meant to be a lubricant.
6. Reassemble the filter and install it on the engine, making sure
the rubber base fits securely on the carburetor with no gaps or
air leaks.
