Oil dipstick

To check the oil:
1. Twist and remove the dipstick from the engine.
2. Clean the oil off of the tip of the dipstick.
3. Re-insert the dipstick and turn it until it is fully
seated to get the oil level reading. See Figure 5.1.
4. The oil level is determined by the highest point on
the dipstick that is completely covered with oil.

Dip stick tube removal

To remove/replace the dip stick tube:
1. Remove the blower/air filter housing by following the
procedures described in Chapter 3: Air Intake Sys-
tem.
2. Remove the screw that passes through the flexible
clamp and the dipstick tube mounting flange using a
10 mm wrench. See Figure 5.2.
3. Rotate the tube until the mounting flange clears the
flywheel.
4. Pull the dip stick tube out of the engine block.
5. Inspect the O-rings on the dip stick and the dip stick
tube. Replace if damaged.
6. Install by following the above steps in reverse order.
NOTE: Lubricate the O-rings for installation.
NOTE: Keep extra O-rings on hand. It is very easy to shear the O-rings when installing the dipstick tube.
NOTE: Compressing the O-rings while inserting the dipstick tube will help prevent shearing the O-rings.
