Kubota U -10 slew bearing greaser failure

[Muz]

Hello boys and girls .. tonights lesson is about observation , and the rumbling feelings you sometimes get in your bottom .................... Was working one of my 3/4 tonners last week and felt a slightly uneven slew function when rotating the digger .. turns out the bearing hadn't been getting any grease due to a burst greaser feed pipe..

You can see the hole in it .. dont know why it burst ?.. most likely because of fouling in the bearing which meant a high pressure build up in the pipe when grease was pumped in.. and the pipe blew.

No fekin olives though .. had to use the plastic ones..on a copper pipe .. as I didnt have proper plastic replacement pipe and... those fookers blew off .. still ... should have cleaned out the connector like a proper plant boy wot ay am .. so after that done.... she greased up nicely .. good old fashioned story dont pump those nipples too hard boys .. if she blows ...no lube is a rough ride to disaster
