The TRX 2.5R Racing Engine
The Air Filter
The TRX 2.5R Racing Engine air filter is specifically 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 2.5R Racing Engine 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 run time, even if the filter
looks clean.
This includes the break-in time. Clean your air filter after
break-in.
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 run
time. 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 assembly firmly to the
side to release it.
Do not pull
straight up.
2.
Disassemble the filter. Pull the
rubber air filter neck 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 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 off-road motorcycle and ATV engines.This type
of filter oil is available at motorcycle pro-shops. 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. The filter
element should be evenly colored by the oil. Even color indicates
that the oil is distributed evenly.
Do not
squeeze out excess oil.
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 filter neck fits securely on the carburetor with no gaps or
air leaks.
Clean your air filter after
every hour of run time to
avoid engine damage,
even if the filter looks
clean.
If you use compressed air
to dry your air filter
assembly, wear safety
glasses and avoid directing
compressed air toward
your skin.
If foam filter oil is not
available, clean 30 or 40
weight motor oil can be
substituted, but is not
preferred. Never run the
engine without a properly
oiled filter!
