Looking for ideas to clear a grease passageway.
edit: added a pic of where its plugged
This is the lower boom pivot pin on a KX41 mini-excavator. The passageways to the left side bushing (black) are plugged. Can't get any pressure because the grease passes by and out the right side.. In the pic it's wet because I've soaked it down with PB Blaster penetrating oil.
Wiggling the hydraulics, I can see movement (a little slop) in all joints except the far left side of the orange clevis. Which is OK. I removed the crossbolt and hammered on the pin, HARD, It doesn't move & will require a press I think.
Can anybody suggest any more tricks (before I get serious and press the pin out)? I don't have a press, will have to build one. The plan is to drive it to the left until the grease hole emerges, and clear it out. If I could get the joint to accept some grease without having to press that pin out, I'd prefer that.
