    Excavator hydraulic thumbs

    Thanks guys. I didn't know of progressive link thumbs so that information was very useful. I'll fabricate this thumb up myself (when I have time, groan, very busy right now) and will model up a progressive link version in CAD to see how it fits. I think it will likely be unnecessarily...

    Bobcat 324 Thumb

    Agree, the first picture you linked to doesn't look like any factory thumbs I've seen, but the only photos I've seen have been more like the second photo ie from a distance. That one definitely looks like a Bobcat thumb to me. You can see how the mounting plate is the same grey colour as the...

    Bobcat 324 Thumb

    Awesome, thanks 1ton. Is that an original Bobcat thumb? From what I can understand, unlike virtually every other machine I've seen, the ears for the cylinder mount are welded to a plate and that plate is in turn attached to the dipper. I presume that's because the steel being used for the arm...

    Bobcat 324 Thumb

    Obviously I have spent quite a lot of time trying to Google this before asking here. I was not able to find any images that clearly showed how the original Bobcat thumb was attached to the dipper, nor were there any pictures of 324s with the thumb clearly displayed such that I would be able to...

    Bobcat 324 Thumb

    Yes, I have obviously done that. Perhaps you would be so kind to send a link to a photo(s) obtained through Google that shows specifically what I asked in my first 2 sentences?

    How long do you expect your machines to last?

    5-10,000 hrs trouble free out of a mini excavator! Wow, you're more of an optimist than I am. I measure my time in this malarkey in months and not decades like some of you guys, but most of the minis I've seen have been well and truly rooted by 3-4000 hrs. My own machine has under 700 hrs on it...

    Excavator hydraulic thumbs

    Without dragging the thread off topic too much, what do you do on a machine like that where there's no provision for a thumb on it as standard? Do you weld ears to the dipper? I agree with the sentiments about Japanese machinery. I'm a very newcomer to this field and don't know much about it...

    How long do you expect your machines to last?

    Hopefully others will agree that it's a good question :) I think what's the appropriate approach will depend on the individual's situation. For many people any downtime costs a lot of money, and once a machine starts to need unscheduled work it's gone. They don't wrench on the machines...

    How long do you expect your machines to last?

    I'm curious as to how many hours members here feel their different types of machines will give before they generally start to need money put back in to them to keep them reliable? I appreciate that's a very general question and will depend on their usage, how they're serviced and generally...

    Bobcat 324 Thumb

    Nobody has a thumb on their 324?

    Leaking final drive.

    Cool, thanks! That was lucky. I'm hoping for the same from mine, but don't think I will have the same luck. Good to know it sometimes does clear though.

    Bobcat 324 Thumb

    I can see the value of adding a thumb to the 324, but don't know how the genuine Bobcat thumb is attached to the dipper. Would anyone have any pictures and specifics of their thumb, or at least tell me how they are attached? Obviously I could just weld something on, but I try to keep...

    Leaking final drive.

    Thanks, the definition I have is; Face Seal (feɪs siːl): a device used to distribute oil over a wide area, at the most inconvenient time, resulting in obscenely costly repairs and general misery to mankind. ;)

    Leaking final drive.

    Aren't the face seals purely on the planetary gear side of the drive?

    Do Face Seals ever self-clear?

    I have recently picked up a little Bobcat 324 Excavator and just went through it with all the regular servicing. I'm trying to get on top of all the problems it has before it starts being used too much, as I know they will then just be accepted and never fixed. I noted that one of the final...

    What is the most common excavator control pattern in Australia?

    Thanks, that was close to what I was doing, but with a digging bucket with a blade welded to the teeth. I was removing a large Jacaranda tree stump, growing amongst a large rock. The spoil was being placed on finished lawn. Once the stump was (finally) out I reached out as far as I could and...

    What is the most common excavator control pattern in Australia?

    Thanks mate. I'll leave it as it is then. I'll ask my mate why his is different, the other way is the way most backhoes are set up right? I have no idea why the Wikipedia entry is wrong. It feels pretty natural and seems to be coming along well. I've been practicing by grading, I'm not too good...

    What is the most common excavator control pattern in Australia?

    I've done a search and can't find the answer to the question as to which is the normally used excavator control pattern in Australia? I know the topic has been done to death here, but the majority of information on the net comes from North America, and it often varies from elsewhere in the...
