SERVICE PROCEDURE
Air Cleaner Element - Install
NOTICE
Do not use any damaged gasket or seal or element with
●
damaged pleats.
Cleaning the element or O-ring after one year has passed
●
and using them again will cause problems. Replace them
with new parts.
The seal portion on imitation parts lacks precision, and
●
allows the entry of dust, which leads to damage of the
engine. Do not use such imitation parts.
Do not run the engine with the inner element removed. It
●
will cause damage to the engine.
1. Check that there is no dirt or oil stuck to the seal portion of the
new element or cleaned element. Wipe off any dirt or oil.
2. When the outer element has been removed, check that the
inner element has not come out of position and is not at an
angle. If at an angle, insert your hand and push it in straight.
3. Push the outer element in straight with your hand when
installing it to the air cleaner body.
If the element is held and rocked lightly up and down and to
the left and right while pushing it in, the element can be
inserted easily.
NOTICE
When inserting the element, if the rubber at the tip is
swollen or the outer element is not pushed in straight, and
cover (6) is assembled by force to hook (2), there is danger
that the hook and air cleaner body may be damaged, so be
careful when assembling.
4. Install cover (6) as follows.
Align cover (6) with the element.
❍
Hook the tip of hook (2) to the protruding part of the air
❍
cleaner body and lock it in position.
When locking hooks (2) in position, apply the hooks in
❍
turn on opposite sides (top, bottom, left, right) in the same
way as when tightening bolts.
Install cover (6) so that the evacuator is facing the
❍
ground.
When cover (6) is installed, check that the clearance
❍
between the air cleaner body and cover (6) is not too
large.
If it is too large, install again.
