Ed Kennell 35,750 #3 Posted April 24, 2016 Yep, 10W-30 motor oil. If your 520 has a hydraulic lift it should have a Eaton 1100 and it takes 5 qts. If it is a manual lift it has a Eaton 700 and takes 3.5 qts. Oh, to the Share this post Link to post Share on other sites

DougC 2,641 #6 Posted April 24, 2016 What ever brand you choose set the quarts of oil in the sun for about an hour before you refill your trans. That will speed up the sometimes slow and frustrating refill process. Share this post Link to post Share on other sites
