How
to do a Complete Softail EVO Oil Change and Flush |
| This how-to
is applicable to 1984 to 1999 Harley Davidson Softails, although
it may be helpful for other HD Models, especially with Evolution
motors. These pictures and steps are from a 1993
FXSTS. |
| |
|
|
Step
1:
Warm up your motorcycle
to normal operating temperature. This will help the oil drain
easier, and also make sure any contaminants are suspended in the
oil. Locate the oil tank drain hose, which is clamped to the frame
to the left of the transmission, below the starter. |
| |
|
|
|
|
Step
2:
Loosen the hose clamp
with a screwdriver or a 1/4" socket, and remove the hose
plug. |
| |
|
|
|
|
Step
3:
Drain the oil. Once
the oil tank has completely drained, replace the hose plug and
tighten the hose clamp. |
| |
|
|
|
|
Step
4:
Locate the oil filter
at the front of the engine. You should be able to twist it loose
(counterclockwise) with just your hands, but if the person that
installed it overtightened it, you may need a filter wrench.
|
| |
|
|
|
|
Step
5:
Wipe the oil filter
mounting surface clean with a rag. |
| |
|
|
|
|
| |
|
|
|
|
Step
6:
Dump a little fresh
oil into the new oil filter, and be sure to lubricate the filter
gasket with some of the oil. Reinstall the oil filter, twisting
it clockwise until the gasket just touches the oil filter mount,
and then tighten another 1/2 to 3/4 turn. Do not overtighten.
|
| |
|
|
 |
|
Step
7:
Add 2-1/2 to 3 quarts
of fresh oil to the oil tank, and reinstall the filler cap. Most
people stop at this step, and don't flush all of the dirty oil
out of their crankcase. It's a little extra effort, but it's worth
it. |
| |
|
|
 |
|
Step
8:
Locate the oil pump
return line. This should be the right-most hose (the one closest
to you when looking at the oil tank from the right side). Loosen
the hose clamp. If you've never had this oil line disconnected
from the oil tank, you may still have the stock hose clamp. You'll
have to destroy this clamp to remove it, but you can easily replace
it with a standard screw-type hose clamp. |
| |
|
|
 |
|
Step
9:
Once this oil line is
disconnected from the oil tank, insert one end of a piece of clear
plastic hose into the end of the oil line. Insert the other end
into your oil pan (or an empty quart of oil). |
| |
|
|
 |
|
Step
9:
Start your motorcycle,
and open the throttle a little bit to get the oil pumping. You
should see dirty oil begin to flow through the clear hose. Let
your bike run for about 30 seconds, and then hit the kill switch
and add more oil to your oil tank. You may have to repeat this
process several times until you see fresh oil start to flow through
the clear hose. The advantage of draining the dirty oil into an
empty quart container is that you'll be able to measure exactly
how much to replace. |
| |
|
|
| |
|
Step
10:
Remove the clear hose
from the oil pump return line, and reconnect to the oil tank.
Reinstall and tighten the hose clamp. |
| |
|
|
| |
|
Step
11:
Start your motorcycle
and check for leaks at the oil tank drain hose plug, the oil filter
gasket, and the oil pump return line. That's it! |
