The simple answer is yes. Water contamination is one of the worst contaminants that can cause the filter to swell and stop oil circulation.

This filter does not have the built in bypass that db2d points out so I'll have to do some research to find a filter that complies. I went with this filter because the large base allowed for more and larger passages to be included insuring that I did not restrict oil flow. This filter uses a 1 1/2" x 16 thread and a 3.59 O ring ID. The PH3786 is normally used on Ford 3/4 ton econovans. The XG3786 has an anti drain back valve but no bypass.

I've written Fram for recommendations, we'll see what they come back with.

Briefly- The canister type was a full flow system with a built in pressure relief mechanism that ensures that the engine is not starved of oil if the element becomes blocked.
Most screw on filters have this relief system built in, but not all. The relief system pressure should conform to DB specification of 10 PSI
So then, db2d, in looking back through the replies, ollek mentions buying an 1190 or 1194 for a spin on filter. Instead of spending thousands of dollars on a tractor to get a filter, could an adaptor be made to fit one of the 1190/1194 filters to the 885? Would those filters meet the 10 psi relief system spec?

I am sure an adaptation could be made but I cannot see what advantages could be gained and from a collectors point of view it would be a no no.
The pressure relief is the same for both types.

I bought one of those filters but the threaded hole is too small. That’s as far as I got.

Regarding screw on filters if they have a by pass valve it will be a valve at the end of the center hole -the bottom end - when viewing the center hole, it can usually be pushed with a suitable CLEAN object to confirm it moves. The flap under holes on face of filters is a non return valve that stops filter emptying when engine is stopped.

Thanks Gard,

After a good deal of research and trial and error what I found is;
it is very possible to make such an adaptor, however little or no benefit will be realized from it. The filter I chose was a Fram PH3786 oil filter due to the large thread, 1 1/2" by 16, this filter was also necessary for it larger diameter base 3.59 inch inside diameter seal. The large base is neccessary to match with the large dimensions of the orginial cansiter. This filter does not employ a anti-drain valve or a by-pass valve. The fram XG3786 could be used and it does have an anti-drain fucntion, still no by-pass. When starting the engine after the oil has had time to settle, 18 hours in my test, the engine ran 12 seconds before registering any oil pressure. This in my opinion is too long. When the engine has been shut down and restarted in a matter of minutes it takes 4 seconds to indicate a rise. I'm assuming that it is due to the large volume of the new filter. I contacted Fram and their recommendation was to use a P3779 which is a hydraulic filter that has a by-pass valve and the same dimensions as the PH3786, these are not easily located and cost around 40 us dollars vs 18 dollars for the Napa (wix) 1313 canister filter.

In the end, when you remove a spin-on filter you still spill oil and make a mess, admittedly not as much as a canister. However, the canister was designed for the tractor and incorporates the correct parameters. I prefer the piece of mind that comes from running the factory design rather than an improvised set-up that may have overlooked design requirements or offer more opportunities for failure. Thanks for everyones' input it was an interesting project.
