I have a Bomag BP18/45-2 and it started leaking oil from the exciter box. So I ordered a new seal for it and now I'm wondering what type of oil it takes. I found a brochure from Bomag and they call it a sealed, maintenance free exciter unit. So they don't list any maintenance info for it. Does anyone have experience with these? Thanks
Standard 15W40 diesel oil, but usually just gets the same oil as the engine.
Interesting. I had assumed some sort of gear lube but given the speed this spins at, motor oil makes more sense. Thanks
Pulled the pulley off the shaft this morning and discovered a tiny bit of play in the bearing. Now I need to try to figure out how to get it apart. It's a one piece case as far as I can tell so I'm guessing everything is pressed in.
A little more progress today
New bearings arrived, put all the parts in the ultrasonic cleaner, and when I started to reassemble, I discovered that I had overlooked the groove in the seal wear sleeve. Going to try to track down a new sleeve. Hopefully I don't have to order from the Bomag dealer.
Update: found a wear sleeve but it had a 10 week lead time. Then I was too lazy to work on it in the cold this winter. But I got the new sleeve installed and am planning to reassemble today.
Got it all back together but there is still some radial play in the shaft even with a new bearing. I tested it for a few minutes but no leaks so hopefully it's ok. Is a small amount of play normal with these two piece bearings?
Yes.
Thanks. I won't worry about it then
