Pat See below from my shop manual. The oil is dependent upon the transmission model. I think warming the transmission before an oil change is a good idea.
Transmission Oil Transmission models KM2A, KM2C, KM2P, KM3A und KM3P The recommended transmission oil is an engine oil that meets API classification CC. The recommended viscosity is SAE IOW-30. Change the transmission oil after every 250 hours of operation. Transmission models KBWI0D and KBWI0E The recommended transmission oil is automatic transmission oil (ATF). The oil must be classified a Dexron oil. Change the transmission oil after every 250 hours of operation. Mike S/V Persuasion C&C 37 K/CB From: Pat Nevitt Sent: Friday, September 07, 2012 2:49 PM To: cnc-list@cnc-list.com Subject: Stus-List Transmission oil Is it necessary to use a marine grade oil in the transmission of a Yanmar? For the engine I always use the marine grade stuff, but it seems to me that the manual isn't specific regarding the transmission. Should you run the engine and put the transmission in gear for 15 minutes or so to warm the oil up before you change it like you do with a car? Seems to make sense, but again, I didn't see that in the manual. -------------------------------------------------------------------------------- _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
