Transmission oil filter case for Komatsu motor graders

The 2321612120, 232-16-12120 CASE KOMATSU is a Komatsu motor grader spare part publicly identified as CASEand linked to the transmission oil filter section in multiple parts listings. The strongest public evidence places this part in the transmission filter assembly of grader models such as GD405A-1, GD505A-2, GD511A-1, GD521A-1, GD605A-3, GD605A-3US, GD611A-1, and GD621A-1.

From the product images, this part appears to be a cylindrical metal housing with a flanged mounting face and multiple threaded holes, which is consistent with a filter case or filter canister housing rather than a structural bracket or gear component. That shape-based description comes from the images you provided, while the transmission oil filter identification is supported by the public sources.

What is 2321612120, 232-16-12120 CASE KOMATSU?

Public parts sources identify 232-16-12120 simply as CASE, but the machine section gives the real functional context. A GD621A-1 parts page lists it under TRANSMISSION OIL FILTER (#10001-10025), and a GD605A-1 page also places the same number in the TRANSMISSION FILTER section. A broader cross-model reference page confirms that 232-16-12120 CASE is used across multiple Komatsu motor graders.

For your website, the safest and strongest positioning is:

Core product identity

• Part number: 2321612120 / 232-16-12120
• Product name: CASE
• Machine area: transmission oil filter / transmission filter housing
• Machine type: Komatsu motor grader

Why this part matters

A transmission oil filter case is an important housing component in the grader power train. It helps contain and support the filter section that protects transmission oil flow from contamination. The public sources place this part directly in the transmission oil filter area, which supports describing it as a working transmission filter housing rather than a generic cover.

In practical service terms, this matters because the transmission system depends on clean lubrication and controlled oil circulation. If the filter housing is damaged, worn, cracked, or improperly matched, the serviceability and sealing quality of the transmission filter assembly can be affected. That performance explanation is a mechanical inference based on the documented filter location and the housing-style form shown in the images.

Compatible KOMATSU models

The strongest public model references for 232-16-12120 CASE include:

• GD405A-1

Another public catalog-style result also associates the same number with broader grader families such as GD305A, GD355A, GD405A, GD505A, GD511A, GD521A, GD605A, GD611A, GD621A, GD621R, and GD623A, but because that result is a summarized snippet rather than a fully expanded factory page, the shorter model list above is the safer fitment list to publish.

Important fitment note

Final compatibility should always be confirmed by:

• exact part number
• machine model
• serial number
• transmission filter diagram reference

That is especially important for grader power-train parts, because similar housings can differ across serial ranges.

Product function and working characteristics

The 2321612120, 232-16-12120 CASE KOMATSU is best described as a filter housing case used in the transmission oil filter assembly of Komatsu graders. The public sources support its location in the transmission filter section, and the images show the kind of closed cylindrical case shape expected for that job.

For workshops and fleet owners, this part is relevant during:

• transmission filter housing replacement
• transmission system service
• grader rebuild work
• repair after housing damage or corrosion
• exact-number replacement during overhaul

These uses are grounded in the published machine section and the product form visible in the images.

Key benefits of 2321612120, 232-16-12120 CASE KOMATSU
