You keep track of the hours on the oil, right? If it is time,
replace the old oil filter while the oil is draining. Machines
vary, but you usually start by removing the two oil-filter
cover bolts. When that is removed, pull the oil filter out of
the engine case; however, be careful not to lose the oil-filter spring that sits behind it.
INSTALLING A NEW OIL FILTER
Install the new filter onto the oil-filter cover and set the
oil-filter spring on the back side of the filter where it will
sit in the recess. Then install the entire filter assembly,
making sure the spring doesn’t fall out of the back of the
filter. Reinstall the two filter cover bolts and tighten them
to OEM torque specs.
REINSTALLING THE DRAIN BOLT
By now the engine and transmission oil should be
drained completely. We suggest installing new crush
washers on the oil-drain bolts, as they’re usually good for
one use. Once those are installed, you can install the drain
plugs and tighten them to OEM torque specs.
FILLING THE ENGINE WITH NEW OIL
Next, remove the oil-fill plug and fill the engine and
transmission with the correct oil. Check your service
manual for what oil weight you should be using in your
quad. Be sure to run the quad for at least a few minutes,
because the engine oil level will be lower when it cools
down. Since we installed a new filter, it will take a bit more
oil than normal.
