Sourcing Guide
A practical guide to confirming OTX oil filter assemblies by catalog code, mounting layout, connection ports, reference number and old-part photos.
An oil filter assembly is not matched in the same way as a standard spin-on filter. The housing, mounting plate, connection ports, sealing faces and installed clearance can all affect whether a replacement is suitable. For maintenance buyers, the safest starting point is the exact catalog code or reference number, followed by clear photos of the removed assembly.
This guide covers the OTX oil filter assembly range TO 0026ZC-01 to TO 0029ZC-02. It is intended to help buyers prepare accurate information before requesting a quotation for an oil filter assembly or a broader maintenance-parts order.
A complete assembly may include the filter canister, cast head, mounting bracket and threaded connections. Two assemblies can use similar-looking filter elements while having different mounting-hole positions, inlet and outlet orientation, thread type or bracket clearance. Replacing only by the appearance of the canister can lead to an incorrect connection or installation position.
For that reason, compare the complete removed unit rather than only the replaceable filter. Photograph the mounting plate, every port, the seal area and any visible casting or OE marking.
The current catalog record groups the following code and reference clues. They are useful for matching, but should not be treated as a universal interchange list:
| OTX Catalog Code | Reference Clue in Current Record | Before Ordering |
|---|---|---|
| TO 0026ZC-01 | 150101200005B1A, JX1013 | Confirm complete housing shape, bracket and connection layout. |
| TO 0027ZC-01 | JX0810Y oil filter assembly, tall version | Compare overall height and mounting clearance. |
| TO 0028ZC-01 | JX0810Y oil filter assembly, FB version | Confirm the exact head and port orientation. |
| TO 0029ZC-01 | WB202, JX0810B assembly | Check mounting holes, seals and inlet/outlet threads. |
| TO 0029ZC-02 | WB202 assembly | Send a full old-part photo and the number on the removed unit. |
Reference labels from a catalog can describe a related service direction, while the actual assembly may still differ by engine configuration or installation layout. The complete code, physical comparison and application information should agree before a replacement is confirmed.
Take one front view, one side view, one view of the mounting plate and close photos of each connection. If the assembly is still installed, add a wider photo showing its location on the engine. A ruler beside the unit helps when dimensions are not listed. Avoid dark or cropped images that hide the bracket or ports.
Oil filter assemblies are often purchased together with oil filters, fuel filters, seals, hoses and other maintenance parts. Keeping uncertain items marked for confirmation within one purchase list is more useful than forcing an assumed match. Once the assembly is confirmed, related service items can be reviewed in the same mixed shipment.
For a precise quotation, send the OTX code or OE number, truck and engine details, quantity, photos of the complete old assembly, mounting plate, ports and any measurements you have. For a larger order, attach the complete parts list so filter, brake and chassis service items can be checked together.
Send an oil filter assembly inquiry with the available details. The final selection will be checked against the documented code and the physical application information before quotation.
Use this guide to organize a clearer quote request instead of choosing from a short product list.
Part number, truck brand, model, engine model, chassis number and old-part photos help confirm the correct replacement before quotation.
Filters, brake parts, clutch parts, chassis parts, cab parts, bearings, sensors and assemblies can be checked together for one practical order.
Share quantity, packing preference and whether the order is for fleet repair, workshop use or distributor stock.
Send part numbers, truck models, chassis numbers, old-part photos or sample photos. We can help check multiple items and combine them into a practical export order.
