First off, please forgive me me if I am not using this forum correctly. This is my first day here. I purchased a 520 H last spring. I am servicing it now for this years mowing season. I am a little stumped on a matter with the transmission fluid filter. Every string I have seen shows a NAPA or WIX 1410 as the correct filter. The tractor now has a Onan 122-0800. From what I can determine, that is actually a engine oil filter. I have the NAPA 1410 and it is a larger diameter that the Onan 122-0800. Am I ok to use the NAPA 1410 in place of the filter on the tractor now?
