E7 350 Oil Filter Question

[sbrem]

Probably a dumb question, but on this E7 is the cartridge next to the spin on oil filters also a replaceable filter?

That's the "Centrimax" bypass type oil filter.

Yes, it needs to be changed too, Mack recommends changing it at every oil change, I used to change the spin on filters every change, and the centrimax every other oil change.

You take off that rubber hose on the bottom, use a filter wrench to remove the canister (put the filter wrench at the bottom of the canister to avoid crushing or deforming it).

Throw out the element, wash out the canister and place a new element in it, and a new O ring at the top of the canister and reinstall.

If that rubber hose looks sh*tty, replace it with a new one.

Thanks for the quick answer Herb. Very helpful! Do you by any chance know the filter number off the top of your head? Any filter brand will do, I can cross reference it to what I will be getting. Thanks again!

I think it was 236GB244 on the ones I had, but the best thing to do is pull it apart and get the number off the element that's in there.

Ok. Thanks again.
