Overview – SPARK PLUG ADAPTER TUBE 164678 Series
Built to Cummins specifications, the SPARK PLUG ADAPTER TUBE 164678 serves Cummins engine positions as the spark-plug adapter tube routing the lead to the plug; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
A spark plug adapter tube that routes the lead and seals the passage at the spark plug in the ignition lead path, so the lead routing stays sealed and aligned. It carries the service life the ignition lead path depends on, so a true, correctly specified unit keeps the crack and leak from the passage admits air or the lead fouls.
Applicable Models & Applications
Used at Cummins Hydraulic Parts positions specifying this SPARK PLUG ADAPTER TUBE. Match the bore, port and seal face against your old unit – Hydraulic Parts parts differ in how they seat and bolt.
Maintenance & Replacement
Inspect for wear and a loose fit at every service. A spark plug adapter tube that has begun to fail lets the lead routing drift, and the drift is what causes the crack and leak.
Confirm the spark plug adapter tube seats and the fixings hold on fit. A unit canted in its bolts lets the lead routing move, and the move is where it fails.
Replace rather than repair a failed one where the part allows. A spark plug adapter tube reused past its life returns the same fault, and the fault is what stops the machine.
Keep the correct spark plug adapter tube for your hydraulic parts on the bench. It is cheaper than the downstream failure, and it is exactly the part missing when a service needs doing today.
