Overview – OIL DRAIN PLUG ASSEMBLY 3046942-20
The Cummins OIL DRAIN PLUG ASSEMBLY 3046942-20 is specified for Cummins oil-pan and tank drain positions as the oil drain plug assembly and is supplied to the original dimensional and material standard.
Parts Characteristics
An oil drain plug assembly – plug, seal washer and retainer – that closes the drain port and keeps oil in the pan or tank until the next service. It is the part that, done wrong, dumps the whole sump on the ground, so a correct assembly with a fresh seal keeps the oil where it belongs.
Applicable Models & Applications
Used at Cummins drain positions specifying this plug assembly. Match the thread, head and seal against your old plug – drain plugs differ in how they seat and seal.
Maintenance & Replacement
Replace the seal washer with the plug at every oil service. A plug onto a crushed old washer weeps, and the weep is what slowly loses the sump.
Confirm the thread is clean and the plug torqued to spec. A plug cross-threaded or over-tightened strips the boss and the boss is the expensive part.
Keep the drain port clean on fit so grit does not score the seat. A plug seated on debris leaks from the first hour.
Keep the common drain-plug assemblies for your engine on the bench. They are consumable at every service, and an engine open on a plug is an engine waiting on a part.
Price Reference (USD)
The OIL DRAIN PLUG ASSEMBLY 3046942-20 generally falls in the USD 5-25 bracket, with expedited freight quoted separately.
Value & Service
We supply brand-new Cummins oil drain plug assemblies with the thread and seal confirmed against your engine, so the drain stays closed and leak-free.
