Its a good point, thank you for flagging! However typically if the bushes are externally greased, there is a groove around the outside of the bush which allows the grease to flow around the outside, meaning you don't need to worry about aligning holes! 😀
Thank you for this helpful video! I have a Hitachi ZX35U-3 with 1,200 hours on the meter. It has a bit of play in the bucket area and could also use some shims to lessen the side to side movement in a couple places. My question is this: Are bushings designed to wear out faster than the pins that they surround? If a machine like this had been maintained properly (which I believe this one was) would one expect to replace pins and bushing given the hours on this machine or would replacing the bushings usually be enough? I know each case is unique but I am just looking for a general guideline if this makes sense.
I’m in the same boat as you here My machine has 1600 hours on and has been greased daily I am now considering new pins aswell so I wouldn’t say it’s unusual They are a wear part
@@embededfabrication4482 Thank you for your response. I will try to find the specs for the pins to see if they have enough wear to warrant replacing. I'm still curious to know if one part wears faster then other (pin versus bushing) but maybe they wear at the same rate. I'll dig deeper... hey that's an excavator pun right there! 😃
No mention that some bushings have a grease hole that have to be aligned properly.

Very well-explained and interesting video
Thank you. Thanks for the support!
Put some grease on the bushing so it'll slide in easier
That's a great tip, thanks for the comment!

They are a wear part
Measure them, there must be a tolerance spec
Of course new pins are better but have you got the money for tgem?

@PJ-ee5mc I think people aren't packing grease on the outside enough
After washing i wipe grease in there with my finger
