Overview – EXPANSION PLUG JP 3092396 Series
If you run Cummins engine block and housing positions as the expansion (core) plug sealing the cast passages, the Cummins EXPANSION PLUG JP 3092396 and its series variants give you flexible sourcing without compromising fit.
Parts Characteristics
A expansion plug jp that seals the sand-cast core passages against leak in the coolant and oil galleries, so the sealing stays sealed tight. It carries the service life the coolant and oil galleries depends on, so a true, correctly specified unit keeps the corrode and weep from the block loses coolant and pressurises.
Applicable Models & Applications
Used at Cummins Hydraulic Parts positions specifying this EXPANSION PLUG JP. 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 expansion plug jp that has begun to fail lets the sealing drift, and the drift is what causes the corrode and weep.
Confirm the expansion plug jp seats and the fixings hold on fit. A unit canted in its bolts lets the sealing move, and the move is where it fails.
Replace rather than repair a failed one where the part allows. A expansion plug jp reused past its life returns the same fault, and the fault is what stops the machine.
Keep the correct expansion plug jp 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.
