Oil Filters for my Twenty

hi, i have a 25 with the same set up. My 25 is missing the filters so i dont kno how it works. i asked on here a long time ago and didnt get anywhere. I still havent figured out what to do. i couldnt see where a small spin on would hurt its better than none. Would just have a to figure out an adapter of some sort. I have a brand new engine just haven't put it back together yet. 3c-445 ian

Are your filter setups like this?

This is the filter setup that was on the big Twenty I hauled home for parts, I can't remember for sure now how it was plumbed, but I do believe the oil has to flow through the center tubes and is forced out through the stacks of felt washers and into the reservoir where it drains back to the sump. It is only a bypass filter setup, meaning it doesn't filter 100% of the oil being circulated. That's about all I remember for now, I'll have to find the parts and dig them out to study them to be able to tell you more.

If I can remember when I get home I will look up the # on the filter I used as a replacement and what I did not use it. If I remember this is a full flow filter system with all oil being filtered before going to the engine. The later filters were bypass filters.

I found some picture that I had saved on my computer. I hope that this will help. The filter that I used is a Caterpillar 4A332. This number has also been discontinued but it changes up to a new number that I can not remember. The 4A332 filter is just about the same OD as the felt washers but it is longer than the stack of felt washers so you will either need to find a new spring or cut the old spring off so that it will hold the steel washers tight against the new filter. As Throw the four steel pins away that hold the felt and steel washers together. I hope the pictures help.
