Air Filter

Going to change out my Cummins ISC engine air filter. Are there any tips to make this task easier?

These are not Cummins parts anyway. Cummins specifies the required air flow and the chassis builder installs the filter. Most of our coaches use a Eco or Ecolite which was designed and continues to be produced by Farr. Don't know who owns Farr now but all the filters of this design are from one producer & private labeled.

The big caveat with these filters is in cleaning up the inside of all the connections and making sure that the connectors are air tight and leak free. An air leak on the clean side of your filter can cause you to need an engine rebuild.

If you take it to a shop, even Cummins, they will have there newest, lowest paid guy doing your work because it's not technical. It is very important however.

While it can be done from the rear. I always change the air filter from the top. Gives me more room to work.

Thanks for the replies... I can't get at this, from the top, unless I'm missing something. There is not enough room above the filter. Probably different in others coaches...

I've been buying air filters for my 2002 ISB 300 hp Cummins from Filterbarn.com Changing the air filter on my KSDP takes less than 15 minutes. Sorry to hear you folks with the ISC are having such a difficult time.
