Any one know if the CRANKCASE BREATHER OIL SEPARATOR is a serviceable item, meaning is there a way to clean them or do you just leave them alone etc. Or if they need to be cleaned/serviced what is the preferred method, thanks I have D2848 LE403's. I believe the it is the same part for many of the mechanical engines in the 284....style Thanks for any input
I remember this. Well, bits and pieces. Some slow brain cells on this were dissolved a few years ago (lack of use). Case vent and the case gases went before the turbo. Just a trap consolidating the oil to drain back into the block. Don't remember anything in the manual. I recall tearing into a high hour 900CRM. Clean as a bell. Never touched another. Our brother mapism Is a great source and hopefully he can chime in.
I'd go for the latter. Unless there's any specific problem you need to solve, but FWIW I never heard of any related to that component.
I'm a little hazy on details and don't have the info on board with us just now... But I'm pretty sure it was the crankcase breathers that we replaced on our 423s -- to a newer version -- since we were seeing some slight oil burp out the dipsticks, and our MAN guy suggested the older style was the cause. Might not be relevant to the 403s. -Chris
Thank you all for the input, I have had them sitting on the bench for a week and no oil has ran out of them and air flows through them just fine. So I assume all is well with them and they are working as they should. I didn't know if they required a cleaning similar in fashion to say a K&N style filter.
