It looks like an oil filter to me. I have seen similar filters on 15's and 8C's.
so it is a caterpillar part...?
was it an option...?
tks,

I can confirm it is an oil filter as my 15 has the same unit. Gary
Read this post this morning and thought off and on all day, then finally remembered!
I believe that is a "Purolater" brand. A common aftermarket attachment that was installed on Cars, Trucks and Tractors. It is a bypass type, not a full flow.
My unit is a Fram with a Westline Standard R5900 cartridge. Does anybody have a cross for a new filter? Gary
