    komatsu pc75uu-2

    I am seriously considering purchasing a pc75uu-2 from tractorhill in BC.
    Does anyone have any advice for me. It is difficult to purchase online. I want one with a thumb.
    what should I be looking for for asking questions about? it has just over 3000 hrs, new rubber tracks, and has not been repainted,so it does not look like anyone is trying to hide anything. the door is gone.
    Has anyone ever dealt with these people? I will be buying sight unseen. only photo's
    I have tried to find something local but cannot find anything in that size local in the province.

    thank you in advance. asking price is 18 900 plus 3 500 for thumb plus 1 800 freight.

    The 75UU-2 is most likely a gray market machine if it's wierd colors, like purple and blue, stuff like that. But no worries, I've never had any problems getting parts for them in my area from local Kommie dealer. They are fairly solid machines, nothing is easy to get to for repairs though, but that's typical of any zero tail swing machine.

    Buying it without first checking it out might come back to bite you though, it really depends on the "satisfaction guarantee" arrangement the dealer offers, if they offer one.

    Particulars of the 75UU:

    Offset boom joints for sure. 3000 hrs is enough time to start seeing some wear in the articulating joints of the offset boom, but it shouldn't be excessive yet, unless the previous owner has never heard of that handy/messy little invention known as a grease gun. If you go to digging with it, and that offset boom is wobbling all over the place, ummmm, I dunno, my wallet would be reminding me how much I just emptied out of it.

    Boom pre-set potentiometers: They not only allow you to "pre-set" depth and offset limits, but those potentiometers also prevent the operator from whacking cab with the bucket when boom is offset to the left. The systems are reliable, but I've seen many of them that have damaged linkage arms and wiring ripped off from being hit with tree limbs and such. Sometimes an owner will disable the boom position sensor system because they have it so F'd up which allows them to operate the machine. Which is perfectly fine, if you're ok with that. But if the machine is in such disarray, if you ever want to repair it proper, those pots ain't cheap.

    The 4D95L engine: Good engine. But, it better fire off real good with no help from liquid fire. If the motor shows any signs of being worn out, not good. Good replacement engines of that model are near impossible to find, so rebuild is typically your only option, and just the needed parts can easily be around the 5 grand mark.

    Gauge console: Shows the hours, temp, fuel level and such. I've seen them with that console not working and replacement console is around 2 grand.

    Door missing: Well, if you're Ok with that. But if you decide to get a replacement from dealer, you're looking at 5 to 6 grand for that round sliding door and related parts. And better check the cab real good, if it's been bumped into a tree or something (which may explain missing door) and tweaked the cab, you may not be able to get a replacement sliding door to work.

    As far as operating, the 75UU is a decent machine, but I seem to think it was a little slower in operation than comparable machines. And I keep thinking it didn't have high speed drive, could be totally wrong about that though, too much junk in my head. If the machine has been cared for and is in good shape, it's not a bad machine. But if previous owner was rough on it and wore it down to near broke it's back, buying parts will really empty your wallet.
    A good mechanic isn't expensive, he's priceless!

    Yeah, there is little that is reasonably priced in Canada, much better to buy from the US, especially now with the strong $. I bought a Kobelco SK130lc from Tennessee through Machinery Trader in Dec, 2010 and imported it into Manitoba. I sent a local trucker down to fetch it - they were great - very helpful. I checked the vendor out pretty well before I sent any money. Checked for any references I could find. I got him to take extra pictures and email them to me and asked lots of questions as I wasn't going to go down there to look at it. Talked to him on the phone twice. He's a good guy. I believe I got a decent deal. Hope you do too.

    I guess that I should ask them for a video clip of them starting the machine, extending the stick and showing how much play it has. Also ask why the door is missing?

    I met the salesman from Tractorhill at a Richie Bros auction in Vancouver. Nice fellow, helpful info from him. I was looking at a 120 Hitachi that still had the Chinese newspapers on the floor. A lot of those machines are straight off the boat.

    I would say that it is grey market and straight off the boat or possibly someone bought it at auction and traded it in for another machine.
    Keep looking. I wouldn't buy that sight unseen.

    If your buying it sight unseen get it inspected prior to purchase, especially on somthing like that. We were looking at a Hitachi EX60URG and had a guy go inspect it, the dealer literaly sent us pictures of one that had been painted up, but not the one he was selling you. It was pretty bad. Cost about 200-250 but well worth avoiding the headache.
    What kind of tracks? I have one with rubber tracks, if I had the option I'd avoid rubber in favor of steel.
    Like was mentioned before, the Z-boom pins and bushings.......pretty easy to stick a couple grand into them. I'm just getting done going through one and what I've discovered is there are parts of them that are not rebuildable, specifically the 4 main pins in the boom, for whatever reason there are bushings in the middle but not the ends. I've ended up having to get quite a bit done at a local machine shop just because there was no way to fix some of it with factory parts. Mine has 3600 hrs

    They are a handy machine, I agree they don't seem to have the cycle speed/power of other machines but they will get the job done and are great for certain applications. Even with some play in the boom it was a very usable machine. Havnt found any parts you can't get from the dealer but it does come at a price, like anything else.

    What type of work are you looking to do with it?

    Yes that is the machine tootalltimmy. I also have trouble buying without testing it out. That is a great amount of coin for me to invest into something that may end up costing alot more.
    Every time I ask a question, they don't seem to have an answer right away. I asked if all the rollers were fine, and asked if they put the tracks on. the answer was not necessarily? so he did not know if they installed the tracks or it came that way.

    I intend to excavate around our house 1700 feet and install weeping tile. we have stoney claybased soil. so I was told to error on the larger size. I want a thumb as I will be dismantling a airplane hanger with it. I also have problems with our lovely frost boils, I intend to dig them out and put some of our abundant rocks into my driveway. we have at least two weeks that the semi that delivers tires into my yard will not drive in. It may look cool when the driveway flexes like jello, but not when a wheel drops out of sight.
    does anyone have a dealer they reccomend?
    Brandt out of Winnipeg was suppose to check out a hitachi ex60 at their store in red deere. that was a week ago. So I guess they don't really want the business.

    Well I am not having any luck finding something in the price I want to pay. bid on three machines today, hitachi , komatsu , and kobelco. all in the 75 series with hydralic thumbs at the Richie auction in montreal. Anyone have suggestions on a good broker? I think I have to look south of the border to save some money. all went over the 20 mark.

    we bought 75uu-2 in 02 its a 96 model still works great . we got rid of the rubber and went to steel but ours had rubber over type pads and when about 20 was missing the rubber i figured they had to go .The solid rubber band might be better i dont know . One thing to decide is how much slop you can live with in the top of the boom mines getting pretty loose and to make it like new cost around 5000.00 for the 11 pins/bushings needed and thats doing the work myself but overall i would recommend one and they hold there value to give you an idea i paid 22000.00 in 02 with new paint and 2000 hrs .I was offered 20000.00 on trade in 2010 with 4000hrs but cant let go of that style boom sloppy or not .They will work in a much tighter place than the front mounted pivot boom

    Hey WV,
    if you get to thinking about going through your boom let me know and I might be able to give you a heads up on a few things to save you some head aches. One of the big problems is you can replace the 4 big main pins and bushings (I think that was over 2k of the parts cost if you got them from komatsu), but alot of your wear is probably in the castings that arent replaceable. That doesnt mean you cant do things to correct alot of it though and get it to 80-90 percent or better.
