fjh Posted September 11, 2017 Share Posted September 11, 2017 Any one know why the likes of Mercedes and Scania IHC choose to use canister type filters rather Spin on style filters? Is it deemed more enviro friendly ? Just curious! Quote Link to comment Share on other sites More sharing options...
Mack Technician Posted September 11, 2017 Share Posted September 11, 2017 (edited) Your guess is as good as mine FJH. I use to think Mercedes was spooky. They mount high and stick the filter in a bullet proof canister. Some of our off-road engines have multiple oil pumps so you can hold the engine nearly vertical (like a dozer climbing a coal pile) and still pick-up oil. Those machines use upside down spin-on (bottom facing upward from top of engine) with check valves in filter to hold oil during engine-off. Seems like some engineers get a kick out of new ideas, even bad ones. Like plastic surge tanks.

theakerstwo Posted September 12, 2017 Share Posted September 12, 2017 I did the Mercedes school when i was working and we was told that its was cheaper.I think it was around four dollars back in 05.Fuel filter same way and we was told that they were turned upside down so no one could pour dirty fuel in it.They had to be primed to be filled with fuel.

fjh Posted September 12, 2017 Author Share Posted September 12, 2017 (edited) Kev sent me these links! https://www.mann-hummel.com/fileadmin/user_upload/AutomotiveNews/AutomotiveNews_EN/MANN_HUMMEL_Automotive_News_2012-2_en.pdf http://www.us.mahle.com/mahle_north_america/en/news-and-press/press-releases/modularity-and-functional-integration-in-the-engine-periphery-of-commercial-vehicles-7361 As Glenn mentioned in the log run it comes down to Cheap assness! (WONDER Why THE big V aint gone Here yet!) ( CHEAP) And in my mind the the idea of having to disturb those filter inserts ( CROSS contamination )Far worse than filling a filter with clean fuel or oil! So one small vote for the volvo method For now! ( Its only a matter of time till Cheap mode kicks in At the Big V !)

JKuhl Posted September 18, 2017 Share Posted September 18, 2017 What's old is new again. Most cats all use canister type filters now. It lowers their "footprint" by not having all the metal from the spin on type going to the dumpster is what we were told in training.
