What a TD121 Service Uses

An annual engine service normally comes down to the same handful of consumables. For the TD121, all of them can be pulled straight from the genuine catalogue:

  • Filter elements — Genuine oil, fuel and air filter elements carrying a fitment tag for this engine are listed in the filtered collection; match the part against your engine designation and serial number.
  • Fuel filter — the genuine fuel filter catalogued against the TD121 range here is 243405; check its compatibility list against your model.
  • Air filter — Genuine air filters carrying a fitment tag for this engine are listed in the filtered collection; match the part against your engine designation and serial number.
  • Water pump impeller — the genuine impeller catalogued against this engine is 1675944; check the compatibility list on the product page before ordering.
  • Drive belts — Genuine drive belts and tensioners carrying a fitment tag for this engine are listed in the filtered collection; match the part against your engine designation and serial number.
  • Thermostat — Genuine thermostats and cooling-system spares carrying a fitment tag for this engine are listed in the filtered collection; match the part against your engine designation and serial number.
  • Gaskets & seals — Genuine gaskets, O-rings and seals carrying a fitment tag for this engine are listed in the filtered collection; match the part against your engine designation and serial number.
  • Engine oil & coolant — genuine oils and coolant are listed under Oils & Chemicals; always confirm the grade against your engine manual.

Beyond the service list, every TD121-tagged part on the site can be browsed by category: Filters, Service & Repair Kits, Belts & Tensioners and Gaskets & Seals, each narrowed to the engine family.

Not Sure Which Part Fits?

Parts differ within a family by model, build year and specification — two engines with the same designation on the rocker cover can take different filters or impellers depending on serial number. Check the compatibility list on each product page against your engine plate before ordering, or call us on 0412 532 984 with the serial number and we will confirm the right parts for your engine.
