Re: help with tanaka 3.0 grease/gear oil change
i read the manual online and understand how to change the gear oil. what confuses me is that they talk also about changing the grease. They say to drain to remove the propeller and shear pin, remove gear housing cover. Drain grease, reinstall cover and then to fill as descibed in lubrication section. The problem is in the lubrication section they say nothing about grease only about the oil. Also in the lubrication section they simply say that to change the OIL one simply has to remove the oil fill/drain and fill untill full. VERY CONFUSING. Please any help would be greatly appreciated!
They're referring to the lower unit oil as "grease", but rest assured, it's just standard "marine lower unit oil". I lay my Tanaka 3HP on the workbench, remove prop, shear pin, gear housing cover(2 hex bolts), lean the motor over to "pour" the old oil out(don't lose that little thrust washer on the front of the prop shaft), flush gear housing with WD-40 or similar to remove any water, dirt, contamination, blow it out with air hose, pour in new oil up to almost full(to leave room for gears and prop shaft replacement without overflowing), replace gear housing. If your gasket is torn up, clean surfaces good and use a silicone rubber gasket compound to replace it, works fine! Good Luck!
