The 57102 is 10 micro so it will take out much finer particles and still flows 7-9 GPM well with in the flow rates of Sunstrand and Eaton. This is the only filter I use and change it on a semi-annual bases. Actually I use Fleet Guard/Cummins with the same specs just because we can get a good price, they have "Stratospo" technoligy they are on my way home. I do change the filter after 25 hour on a new or rebuild and then go to the semi-annual change. I have never had a system starve for oil on this schedule and only very minor lapping of the plates / if any at all on a tear down.
51307 21 micro and has an 8-11 Lbs bypass. This will keep the system lubed but with unfiltered oil if the filter is ever not serviced as it should be. Not a good filter for a Hydro that does not like dirt AT ALL. I would sooner solve your SQUEAL from the lack of maintenance of the above filter than solve that LACK of traction due to a wiped Hydro from allowing the 51307 feed your hydro unfiltered oil.
