I am considering changing the air filter on my 1978 MC8 from oil bath to paper. I found and purchased 2 Donaldson air cleaners that have potential.
I called Donaldson's tech dept and found the following. The air cleaner assemblies I have will flow 750 cfm @ 6" of vacuum or 890 cfm @ 11 inches of vacuum.Donaldson advises to change a filter @ 20 inches of vacuum. Donaldson has spec's on the 8v71n calling for 850 cfm.
Would you go with one of these air cleaners or ? |

I have paper in my GMC 4108. It's OEM, and I love not having to do the oil bath PM, like I had to do on previous busses.
So, to answer your question, yeah, paper is nice. I'm told it will filter more dust at lower rpms, BUT the oil might filter down further at highway speeds. If you do some tooling around on gravel roads, paper is definitely the way to go. I'd go with the bigger CFM one, too. Unless I don't understand things right, I'd think you'd want to pull as much air with less restriction as possible.
My only rub with my coach is I can't readily find a replacement element. So... let me ask you something. Where did you find the Donaldson housing and how much were they?
Thanks,

In fact I have 2 pairs of air cleaners(4). The configuration is different pair to pair. I purchased 1 pair from Ron The Bus Nut and the other from the local Kenworth dealer. New take offs painted very nicely, however check Ebay I saw a few pairs of stainless steel. After purchasing now the fun begins engineering the mounting and plumbing the air to the engine. If anyone has done this and has a picture please post it. THX Marty |
