Overview — Auxiliary Drive Room Gasket 3076225-20
3076225-20 is the sealing gasket for the auxiliary drive housing joint on CUMMINS diesel engines, sealing the cover or access plate of the auxiliary drive compartment. We can supply this gasket as well as related CUMMINS engine components, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The gasket is cut to the original profile of the auxiliary drive cover joint, with the correct bolt-hole pattern and an opening matched to the cover and housing faces. The material is oil-resistant and remains flexible under engine heat, so it keeps its sealing pressure instead of hardening and weeping. Its thickness matches the original specification so the joint closes fully without distorting the cover, and the surface finish provides a clean seal against both mating faces. As an OEM-spec gasket, it restores the designed sealing force at the joint and prevents oil seepage from the auxiliary drive compartment.
Applicable Models & Applications
This gasket is used on CUMMINS engine families where the auxiliary drive housing is closed by a cover or access plate, including construction, industrial, generator and marine installations. The auxiliary drive compartment carries gear-driven accessories such as pumps, compressors and the fan drive, and the gasket seals the joint against oil splash and pressure inside the housing. Confirm the cover size, bolt pattern and gasket profile against the original gasket removed from your engine before ordering.
Maintenance & Replacement
Check the auxiliary drive cover joint at each service for oil seepage or wetness around the bolt line. A weeping gasket allows oil to build up on the housing, where it collects dust and eventually shows as an oil trail on the machine. When replacing, clean both sealing faces thoroughly and remove all old gasket material without scratching the metal. Fit the new gasket dry or with the sealant specified in the manual, then tighten the cover bolts evenly in the sequence given in the service manual. Check the joint again after the first hot run to confirm the seal has settled.
Price Reference (USD)
The reference price for this Auxiliary Drive Room Gasket (3076225-20) is approximately USD 8 – 25 per unit depending on brand grade, quantity and shipping destination. This is a planning estimate only — confirm current pricing and availability with our sales team before ordering.
Value & Service
This gasket is a low-cost part that is normally replaced whenever the auxiliary drive cover is removed, and we keep 3076225-20 in stock and verify it against the original CUMMINS specification before dispatch. A correctly sealed joint prevents oil leaks that are difficult to trace once the housing is dirty, so we recommend fitting the new gasket every time the cover comes off. Orders can be consolidated with other engine service parts into a single tracked shipment, with quantity pricing available for workshops.
