tractorhogg 612 #1 Posted May 16, 2022 I tried doing a cross reference, but when they gave me 100 different filters I was worried that all would fit, but most wouldn't be right, Can someone tell me the Wx/NAPA filter to use? Thanks Share this post Link to post Share on other sites

daveoman1966 3,758 #3 Posted May 16, 2022 I would NOT trust any after-market filter. Get the OEM filter #102819 (new #79-5270) here for under $25. https://www.rcpw.com/parts-lookup?arisku=102819&arireturnurl=https%3A%2F%2Fwww.rcpw.com%2Flookup%2F%23%2FToro_Consumer%2F71-16OS01%252c_D-160_Automatic_Tractor%252c_1977%2FTransaxle%2Ff9d93417-8b05-4aa1-9e35-2a7266043eeb%2Fc7970827-b9b5-4a71-a327-91977013bb6b&aridescription=See+Supercession%3A+79-5270&aribrandcode=TO 1 Share this post Link to post Share on other sites

squonk 41,310 #6 Posted May 16, 2022 A 51512 or Napa 1521 is an engine oil filter with a bypass in it. You do not want that. I was in the auto part biz for 10 years. The cross reference info available is as only as good as the person who punched the info in. My Napa Prolink says the same thing but use the 1410 2 Share this post Link to post Share on other sites

squonk 41,310 #8 Posted May 17, 2022 The cross reference isn't correct for this application. Not the first time I've seen this happen. You can use the 1521 and 99.9% of the time you won't have a problem. It has the same thread and gasket as the 1410. Use what you want. But 100's of us use the 1410. Read what it says in the link Gary sent you. It says the preferred filter is the 1410 Share this post Link to post Share on other sites
Achto 27,747 #9 Posted May 17, 2022 Top line on that page in bold letters. The preferred transmission filter for all models is a Wix 51410 or Napa 1410 because it does not have a by-pass valve 2 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,090 #12 Posted May 19, 2022 I recall a veteran in the old Yahoo Group making a statement that makes sense. When the 1410 filter gets plugged up the tractor slows down because there is no bypass valve to allow sufficient oil through to meet demand. Replace filter and you are back in business. When a filter with a bypass valve plugs up the valve opens and allows unfiltered oil into the hydro and when it gets weak the tractor slows down or stops because it is worn out. Replace transmission and you are back in business. Which would you prefer? 1 1 Share this post Link to post Share on other sites
