COGENG VOE16213230 E311982 MBS1250 Hydraulic Filter Cross Reference

Original Query Translation:
"Due to the fact that 'COGENG VOE16213230' and 'E311982 / MBS 1250' may belong to different industrial coding systems (speculated to involve engine components and hydraulic or filtration systems respectively), and in the absence of precise technical manuals and production batch comparisons, it is difficult to provide a standardized comparison table. However, based on general industrial logic, they can be distinguished and interpreted from the following dimensions:

1. Speculation on Coding System and Hierarchical Attribution

   • COGENG VOE16213230: The prefix 'VOE' usually points to an Original Equipment Manufacturer (OEM) part number, commonly used for specific vehicle models or construction machinery dedicated components. Such codes are often tied to the internal system of the host manufacturer (e.g., Volvo Construction Equipment) and are applicable only to specific models of that brand, with low compatibility with other brands [citation:1].

   • E311982 / MBS 1250: This group of codes is closer to cross-brand application standards or aftermarket reference numbers. 'E311982' may correspond to an internal code of an international filtration or sealing brand, while 'MBS 1250' might point to a specific size class or performance series, typically used to match multiple brand models.

2. Hypothetical Comparison of Physical Attributes and Technical Parameters
   Since both are likely components of power or hydraulic systems, it is speculated that they have significant differences in the following physical dimensions:

   • Filtration Accuracy and Separation Efficiency: If related to filtration systems, the VOE original code generally strictly follows the micron level set by the host manufacturer (e.g., absolute filtration accuracy) to meet the oil or fuel cleanliness requirements of specific engines; whereas the MBS series may target hydraulic return or pilot oil circuits, with possible differences in accuracy rating or dirt-holding capacity.

   • Mounting Interface and External Dimensions: This is the core criterion for interchangeability. Even if they look similar, E311982 and VOE16213230 may have substantial differences in thread specifications, O-ring diameter, center tube length, or bypass valve opening pressure. Forced replacement may lead to oil leakage or abnormal system pressure.

   • Material and Temperature Resistance: Original parts (VOE) typically use specially formulated filter media for specific working conditions (e.g., high temperature or cold); MBS 1250, as a general-purpose model, may use more cost-effective compatible materials, and its burst resistance or service life may differ from original design specifications.

3. Cross-Application and Exclusivity

   • VOE Code: Often dedicated to specific engine series (e.g., Tier 3 or Stage V emission standard models); using it on non-designated models may affect warranty terms.

   • MBS / E311982 Code: May be widely used in off-highway machinery, generator sets, or industrial pump stations. If this is a filter element, it is highly likely an aftermarket or competitor product developed to replace the VOE code, but in actual selection, it must be verified whether this model explicitly states compatibility with 'VOE16213230'.

4. Selection and Replacement Recommendations
   Before physical measurement, it is recommended to refer to the following principles for judgment:

   • Check OE Cross-Reference: Look up the official catalog of the brand that produces this part (e.g., Mann+Hummel, Donaldson) to confirm whether 'E311982' lists 'VOE16213230' as a compatible object.

   • Measure Key Parameters: Physically compare the mounting hole spacing, thread pitch, O-ring outer diameter, and overall height of the two. Even if the codes differ, if the dimensions are completely identical, interchangeability is speculated.

   • Performance Matching: Prioritize meeting the bypass valve set pressure and Beta Ratio set by the original manufacturer—this is a more important selection criterion than the code number.

Whether they can be replaced ultimately depends on physical measurement results or the cross-reference instructions provided by the component supplier. If convenient, please specify on which equipment (specific brand and model) these two codes were found.

Official Clarification and Technical Explanation Regarding "Two Sizes Exist for VOE16213230"

Core Conclusion: Volvo Construction Equipment (Volvo CE) adheres to a strict "one part number, one specification" principle for its original part numbers. VOE16213230 corresponds to only one set of engineering drawings and dimensional specifications in the Volvo Global Parts Catalog. The original manufacturer does not have two sizes for the same part number.

The claim of "two sizes" circulating in the market, upon traceability analysis, typically originates from the following three non-official scenarios:

1. Mold Differences in Aftermarket / Copy Parts (Most Common Reason)

• Phenomenon: Many domestic supporting manufacturers have developed two sets of production molds ("standard version" and "economy version") for the same model to cover different customer needs or reduce costs.

• Result: The finished products are highly similar in appearance, and the packaging or labels all print "VOE16213230," but there are subtle differences in internal key dimensions (such as center tube length, end cap thickness, and O-ring groove bottom diameter).

• Risk: These are not Volvo original designs but are self-defined standards by suppliers, without any guarantee of original interchangeability.

2. Part Number Confusion (Human Error)

• Phenomenon: Volvo part numbers use combinations of digits and letters, and there are multiple highly similar numbers:

  • VOE16213230 (correct number)

  • VOE16231230 (different digit order)

  • VOE16213320 (different ending digits)

• Result: When manually entering or verbally quoting, sellers can easily confuse these numbers, mistakenly believing they are different batches of the same product.

• Risk: In reality, these three may correspond to completely different filter types (e.g., return filter vs. pilot filter) or mounting interfaces.

3. Mixed Use of Replacement Series Numbers (Information Asymmetry)

• Phenomenon: There exists another independent Volvo part number with similar appearance and "interchangeable fit" but different dimensions (e.g., an earlier version for a different chassis number).

• Result: Some unauthorized sellers, to simplify inventory, group multiple similar part numbers under the "16213230 series" and vaguely tell customers that "there are two sizes, both work."

• Risk: "It fits" does not mean "it works properly." Forced use can cause the bypass valve to open prematurely or lead to filtration failure.

Operational Recommendations for End Users

One Sentence Summary:
VOE16213230 has only the unique size defined by Volvo drawings. If you hear the claim of "two sizes" in the market, it can basically be determined that the supplier is not providing genuine original parts, or there is a coding misinterpretation. For critical hydraulic systems, it is recommended to rely on actual measurement data and request a written cross-reference certification.

Follow-up Query and Analysis Translation:
"Regarding the three codes you mentioned (VOE16213230, E311982, MBS 1250), in the field of construction machinery parts, they usually refer to hydraulic system filters (return filters or pilot filters). Based on industry general databases and aftermarket practices, here is the specific usage description and applicable excavator model analysis for these three codes:

1. VOE16213230 (Original Code)

   • Nature: This is the original part number (Part Number) of Volvo Construction Equipment (Volvo CE).

   • Applicable Models: Mainly used in Volvo EC series medium excavators, specifically including:

     • EC210B / EC210C / EC210D

     • EC240B / EC240C

     • EC290B / EC290C

     • And some EW wheeled excavator series (need to verify chassis number).

   • Usage Instructions: This code is usually a hydraulic return filter, installed on top of the hydraulic tank or in the return line. The replacement interval is generally 1000–2000 working hours, depending on oil cleanliness. Special attention should be paid to the bypass valve opening pressure (usually 2.5–3.5 bar), which must follow original parameters; otherwise, it will affect filtration effectiveness during cold starts.

2. E311982 (OEM Replacement Code)

   • Nature: This is a cross-reference number compiled by internationally renowned filtration brands such as Donaldson for the aftermarket, corresponding to the Volvo original number VOE16213230.

   • Applicable Models: Exactly the same as VOE16213230, i.e., applicable to the above-mentioned Volvo EC210B/C/D, EC240B/C, EC290B/C, etc.

   • Usage Instructions: As a high-quality replacement filter, its filtration accuracy (micron level) and dirt-holding capacity are designed to be equivalent to the original part. The key difference is that E311982 is an independent brand's general-purpose model and may not come with the original anti-counterfeit code, but its material (e.g., glass fiber layer) may offer longer service life under certain working conditions. Before installation, be sure to check the O-ring size (wire diameter) to avoid oil leakage due to batch variations.

3. MBS 1250 (Special Model / Specific Market Code)

   • Nature: This code is relatively special; it is not a common international major brand replacement number but rather tends to be a kit number for specific regional markets or a derivative model of Korean/Japanese brands.

   • Applicable Models: Special caution is needed—MBS 1250 usually does not directly correspond to the Volvo EC series. Based on industry data comparisons, this model is more commonly found on:

     • Hyundai R210LC-9 / R225LC-9 series

     • Doosan DX225LC / DX300LC series

     • Or it may be a pilot filter used on early Volvo B-series models (but with significant size differences from VOE16213230).

   • Usage Instructions: If MBS 1250 is recommended for Volvo excavators, it is likely a non-standard replacement (similar in size but with different length or interface threads). Before use, it is essential to measure the filter's overall height, inner/outer diameters, thread specifications, and bypass valve pressure value. Forcibly installing a mismatched filter may cause hydraulic system aeration due to poor sealing, or in severe cases, trigger alarms or damage the hydraulic pump due to insufficient flow.

Conclusion and Selection Recommendations

Final Operational Recommendations:

• Physically measure and compare the MBS 1250 filter with the existing VOE16213230 filter on the machine, especially the mounting thread diameter and total length.

• If MBS 1250 is recommended by the supplier as a 'substitute,' be sure to request their cross-reference table to confirm that it explicitly states 'Replaces VOE16213230.'

• For Volvo EC series, if you cannot confirm the parameters of MBS 1250, it is better to return it or choose E311982 rather than risk installing it due to similar codes.

If convenient, you can take a photo of the old part and measure the thread diameter at the bottom and the total height of the filter. I can further help determine the actual application model of MBS 1250 based on those specific values."

Key Conclusions

Volvo genuine VOE16213230 → has only one unique standard size (≈13mm). There is no official two-version variant from the factory.

The appearance of two specifications (≈11mm / ≈13mm) on the market is basically due to chaos caused by aftermarket or counterfeit parts. Two typical scenarios:

Scenario ①: Sellers mix up part numbers (most common)

There is a bushing / oil seal with a highly similar appearance that can be easily interchanged. Its actual part number is NOT VOE16213230, but many wholesalers do not bother to distinguish it and simply print VOE16213230 on the label.

As a result, two thicknesses (widths) circulate in the market: ≈11mm and ≈13mm.

Scenario ②: Aftermarket old vs. new molds

Early counterfeit molds had a thickness of 11mm; later improved molds were made to 13mm. Manufacturers still use the same VOE number without differentiating between versions.

⚠️ The two sizes are NOT interchangeable! Consequences of wrong installation:

How purchasing can distinguish and avoid shipping errors

1. Priority: Measure the old part's thickness with calipers to confirm whether you need the 11mm or 13mm version.

2. When placing an order, add a text note: "Thickness: XX mm, do not send the other size."

3. Do not just quote VOE16213230 — also provide the machine model (e.g., EC series? L-series wheel loader?) to help the supplier cross-check.
