Construction features

The filter WIX 51068 is equipped with functional elements typical of spin-on oil filters for engine lubrication circuits, including:

• high-efficiency filter element;
• anti-drainback valve, useful to limit filter drainage and reduce dry start;
• opening pressure of the by-pass valve ranging between 8 and 11 psi (approximately 0.55–0.76 bar);
• burst pressure (burst pressure) of 275 psi (approximately 19 bar).

Applications and usage context

This filter is offered as a solution for those who need the replacement identified by Onan code 0122-0810, with reference to the equivalent WIX 51068. In the nautical and plant engineering fields, oil filters are commonly used in the maintenance of engines and units where the quality of lubrication affects the smooth operation and protection of internal components.

Important note on compatibility: the code 0122-0810 is the corresponding Onan replacement part for WIX 51068. The WIX documentation confirms the technical characteristics of the filter; however Cummins Onan does not publish a complete list of generator set models compatible with this specific code. For this reason, when ordering, it is advisable to verify the replacement code required by the manufacturer or the engine/unit manual.

Operational advantages (from a maintenance perspective)

In a routine maintenance program, replacing the oil filter is a standard practice to keep the lubrication circuit in proper condition.

• Spin-on format: typically faster installation and removal compared to non-screw solutions, with easier handling in scheduled interventions.
• Nominal filtration 21 µm: useful indication for those who must comply with a filtration specification provided by the manufacturer or maintenance procedure.
• Anti-drain valve: supports the management of oil retention in the filter when required by the application.
• By-pass valve: functional element that, within the indicated values, allows oil flow in conditions where flow through the filter media might be restricted.
• Clear cross-reference: equivalence Onan 0122-0810 ↔ WIX 51068, useful for spare parts procurement and inventory management.

Usage and notes for selection/order

Component function

The oil filter has the task of:

• retaining impurities and particles present in the engine oil;
• protecting the components of the lubrication circuit;
• ensuring a proper flow of oil to the engine;
• contributing to the durability and reliability of the generator set.

Recommended checks before purchase

For a correct selection of the replacement part, especially when an official compatibility list by model is not available, it is good practice to verify:

• requested replacement code (e.g. 0122-0810) on manual, nameplate or spare parts list;
• type (spin-on) and thread (3/4″-16 UNF);
• space requirements (height and outer diameter) in relation to the available installation space;
• any maintenance indications from the manufacturer regarding the oil filter and replacement intervals.

Operational notes

During replacement, follow the procedures provided by the engine/set manufacturer and good workshop practices (cleaning the seat, checking the gasket, correct tightening). In case of doubts about the replacement correspondence, it is preferable to rely on the code and on the dimensional/thread data reported in this sheet.
