The T-Series uses oil-wetted wire-gauze filters, not paper. They are cleaned and re-oiled, not replaced — get the oil quantity right and the carbs will thank you.
Step by step
- 01
Unbolt and remove the filter(s)
Take the filter(s) off the SU carburettor intakes. Note orientation and any fibre washers so it goes back the same way.
- 02
Wash out the old oil and dirt
Wash the gauze thoroughly in paraffin (kerosene) or a proprietary parts cleaner until the run-off is clean. Do NOT use petrol (fire risk) or water alone.
- 03
Let it dry completely
Shake off surplus solvent and leave the element to dry fully — any solvent left in the mesh will be pulled into the carburettors.
- 04
Re-oil the gauze
Dip the gauze in light engine oil (SAE 20 is fine) then let it drip until it just stops. The mesh should be wetted, not dripping. Over-oiling restricts airflow and richens the mixture.
- 05
Refit and check
Refit with the correct orientation and washers. Check the carb intakes are still clear of drips.
