Hey all,
I have a question for everyone who has some experiences with JRB pin couplers, I'll try to set this up the best I can.
At work we have mostly Cat excavators with their own quick couplers, but on our Komatsu PC228's we have JRB's. I've had a 48" bucket on for the last week or so and when I try to switch out or just take it off, the coupler seems to not want to "let go" of the bucket without shaking the bucket a bit. It doesn't have any problem with smaller buckets or the felco bucket, just seems to be the big 48" one. I have been greasing it so I don't think the safety latch is getting stuck. Course I can only find one grease fitting and on our Cat's there are 4, but i've looked all around it and only see the one. Am I missing any?:beatsme
This is not the first 228 that's been difficult to drop the 48" bucket off of and I mentioned it to my foreman today and he said that it usually is a little bit more stubborn than other buckets to switch out.
Has anyone else ever experience this problem? Or should I ask him to get a mechanic to look at it, or (hopefully not) am I missing a fitting:Banghead?
