Grease fitting maintainence question

[Ed Miller]

I've got a few grease fittings on my machine that are so plugged up I can't get grease into them.  This is on both the loader and backhoe.   Anyone have any tricks on cleaning things up.  On a couple I've pulled the pins out, taken the fitting out and run a drill into the rust and dirt but I was looking for a way to do it without removing pins.  The backhoe parts are pretty heavy.

Try pulling the fitting out and clearing the crud from the hole and replace with new fittings.
