Inspection procedure
Installation procedure
Inspection: DPF
• Check the inner exhaust channel of DPF for clogging with for-
eign material.
• If clogged, the inner exhaust channel must be cleaned with com-
pressed air or DPF must be replaced.
• If DPF is clogged, this may be due to problems with the engine.
Check the engine and adjust as required. Also check the engine
oil and fuel.
Installation: DPF
• Insert the DPF pipe into the tail pipe until the DPF pipe bottoms
out against the expanded portion of the tail pipe.
Installation: Rubber cushions
• Compress the rubber cushions until the dimensions shown in
the illustration are achieved.
Installation: Clamps
• Tighten the nuts just enough to loosely retain the clamps so that
they can easily be moved.
• Tighten the nut at A until the ends of the clamps at A contact with
each other.
• Completely tighten the nut at B.
CAUTION
• Do not overtighten the nut at B, or the clamps and DPF may
become damaged.
