sight glass

[[email protected]]

I think the sight glass for showing the level of hydraulic fluid in my 742 B is glazed over. Not too long after I bought it (10 yrs ago) I drained the fluid and replaced it all, using the capacity specs in the manual. I couldn't tell then, and still can't see a fluid level thru the glass, but that would be the case if it were low or over-full. The machine runs fine, all the hydraulic functions work perfectly, and there are no leaks. When moved to check the level, I use a 4 ft bamboo stick which goes in at an angle, but the level is obvious. Should I just consider that if it ain't broke, don't fix it, or is there a way of recovering visibility through the glass?

You should be able to buy a new sight glass, but if it runs fine, I wouldn' be too worried, especially if you have verified with the calibrated stick that there is oil in there and it's at a fairly decent level.

Sight glass in my 743 screws out and can be cleaned. Of course, if your tank is full of hydro oil, you will make a mess.
