I renctly changed my blower oil, set the levels at the half way point of the sight windows. After a few days I checked the levels and one side is almost empty and the other is full to the top. Any help would be greatly appreciated.
Did a couple of jobs yesterday, ran the machine about 4 hrs, checked the levels this morning and both were down to almost empty. Took about 3-4 ozs each side to get back up to half way up the sight windows. No sign of any leaks anywhere near the blower. Only a small leak from one of the drain hoses, but that was only about half a teaspoon.
I have only had one blower leak on my Tuthill in 16 years. Mine was leaking out the front of the blower. It turned out to need a new front seal. It so happened my rear oil seal on my engine was leaking at the same time so I got Jondon to fix them both while they had it apart. I've had no further leaks from the blower in like 10 years or better. I don't know if it's possible for the oil to leak into the blower chamber so you wouldn't see it on the outside, but it seems reasonable that it could. If you're losing that much oil it has to be going somewhere. I'd get it checked out before you wind up buying a new blower$$$$$$$$$$$$.
