• OEM code reported on the removed filter or in the spare parts manual;
• comparison of the dimensions (H, D1, D2, D3) with the existing component;
• check of the’threaded connection indicated (D2: 3/4"-16UNF) if relevant to your system.

Operational advantages (from a maintenance perspective)

• Greater order in maintenance: using a replacement with clear codes (OEM and supplier) simplifies reordering and traceability.
• Reduction of incompatibility risk: the presence of dimensions and connection (D2) allows a direct comparison with the installed filter.
• More streamlined intervention: a correctly identified replacement helps limit downtime and incorrect installation attempts.
• Preventive management: filter replacement is part of good practices to keep the fuel circuit clean, especially in contexts where the fuel may be subject to contamination.

Usage and installation notes

The following indications are generic and should always be adapted to the engine manual and manufacturer procedures. If you are unsure about the intervention, it is advisable to consult qualified personnel.

Before purchase: recommended checks

• Compare the codes: check that the existing filter or documentation shows the reference 129470-55703 (or equivalent 12947055703).
• Check the dimensions: check H, D1, D3 and the possible match of the connection 3/4″-16UNF.
• Check the available space: make sure the filter size is compatible with the mounting area.

During replacement: good practices

• Clean the work area: avoid dirt or residues entering the circuit during removal.
• Inspect the seat: check that the support surface and the old filter gasket leave no residues.
