secondary element (2).
NOTE
• The air cleaner uses a dry element.
Never apply oil to it.
• Do not operate the engine with filter element
removed.
4. Install the removed parts.
10.2 Checking DPF differential
pressure pipes and hoses
IMPORTANT
• Be sure to loosen the differential pressure pipe
tightening nut with crowfoot wrench to prevent
the damage of the sensor or pipe.
If it is still hard to loosen, apply the lubricant
spray to threaded portion and soak it with
lubricant.
• Tighten bolts and nuts to their specified torque.
Also tighten the differential pressure pipe
tightening nut to the specified torque with
crowfoot wrench.
Tools required
• Crowfoot wrench
1. Check the DPF differential pressure pipe (2), (3) for
crack, gas leakage and loose mounting nut.
NOTE
• If you find a crack, change the DPF
differential pressure pipe.
• If you find a gas leakage, remove the DPF
differential pressure pipe and wipe off the
anti-seize & lubricating compound.
