What is this part?
Renault 5021170284 identifies the diaphragm fitted inside a Type 27 normal stroke service brake chamber. Type 27 refers to the effective area of the diaphragm — 27 square inches — which is what determines the output force the chamber produces at a given air pressure. The normal stroke designation refers to the travel available: standard-travel service brake chambers. A diaphragm of the wrong Type or the wrong stroke will either not seal correctly or will not deliver full travel, so both figures have to match.
What does this number tell you?
Renault 5021170284 is the number Renault lists for this diaphragm in its own parts catalogue. A vehicle manufacturer does not make the diaphragm — it specifies one and prints its own reference on the box, so this number is what a service manual and a dealer system will recognise.
The same diaphragm is catalogued by WABCO as 897 120 547 4, by DAF as 66619 and by DT Spare Parts as 02.01.42.204777.
