re: Is there a window in the upper filter "head" where you could see a change in color if the plastic part moved due to pressure from a plugged filter?
I received drawings and explanations from Donaldson Filter (they appear to be the OEM supplier for this part). The filter head indeed has a "a window in the upper filter head where you could see a change in color if the plastic part moved". However, my unit has no window, the port is capped off. The service manual says nothing about the "window", or how to know if the filter is in bypass. It appears (?) that MF didn't use that "window" feature, but does use the bypass plastic piece. Although it is hard to believe that pressure on the filter can compress the spring on my unit. I ordered the By-pass indicator assembly 1096245M91 from MF to compare with the one I have in place now.
Here's description from Donaldson:
Dirty oil comes in the inlet port and is directed to the top of the filter assembly by a internal baffle tube. The oil goes down and thru the element from the inside out. As the element becomes dirty the oil pressure on the inside of the element increases until the spring force is overcome then the entire element starts to shift down along with the bypass valve assembly compressing the spring even more and eventually creating a gap between the bypass valve and the baffle assembly. The dirty oil will now go thru the gap created between the baffle and bypass valve and flow out the outlet port. When this happens the filter is in bypass and no fluid is being filtered.
