injector numbers help
 

kca30s46 bosch 543 just pulled it

what are these from? below

kca30s44 bosch 643

same injector?

is there a web site with the numbers

The part of the number starting with K is a code representation of parts on the injector nozzler holder assembly but not the spray nozzle. There may be several vehicles that use the same nozzle holder assembly but have different spray nozzles or nozzle opening pressure settings. Some where stamped on the nozzles you will find a number for example 135bar. The 135bar is the opening pressure of the spray nozzle. One bar is = to 14.5 pounds per squar inch.
A nozzle opening pressure of 135bar= 1957.5 pound per square inch.
The spray nozzle will have its own number stamped on it (which is also a code representing the construction of the parts on the nozzle) but you cannot read it until you take apart the injector.
About 1 year ago I did come across a sit that gave the nozzle holder number, spray nozzle number and the vehicle it was used in. I believe that it was a Dutch site but I no longer have the informion to go back there.

the 2 inj look exact the same, both say 135bar on them

There it is:

Under "Search Via.." option,choose "Direct article search " and paste the numbers-it`ll show the Bosch sale numbers,as well as the MB or other manufacturers` numbers and the vehicles the part is installed on.Some items have a picture...kinda comfortable....

kca30s46 is the nozzle holder from a late OM617.952, will have #240 nozzles.

kca30s44 is the nozzle holder from an OM603.96x, will have #265 nozzles.


They are visually identical, but I'm not sure what the internal differences are between the 44 and 46 holders.

:confused:
