    rebuild hydraulic breaker

    I suppose it depends on the size of hammer and height of the roof/crane. Shops that specialized in hammer work would have a pit to make it easier.

    MB crusher bucket case drain question. Can't really decide if it id dumb or not.

    Great point. I know if I were to setup my own machine, I would run an attachment case drain through a properly rated filter. The issue that I see these days is that guys don't know to look for them. I had a motor fail a couple times, customer couldn't figure it out so just kept throwing motors...

    rebuild hydraulic breaker

    Well I work for NPK so I admit I am a bit biased. But the way the hammer is removed from the bracket, no pit needed. Really no special tools, tie rods can be reused many times over, internals are all replaceable unlike most hammers no boring needed, no bladders or accumulator, simple valve. The...

    NPK hammer nitrogen fill valve

    I realize this is an old thread, but in case anyone is looking for the same info...the kit is pn 7300588, included the charge valve, cap, hose and red metal box for storage. These can be ordered from any NPK dealer and they likely have some laying around the shop they may even give you. A charge...

    MB crusher bucket case drain question. Can't really decide if it id dumb or not.

    It would make sense but I assume you would be using a T to split a -12 into two -8s. If the inside of the T is not large enough diameter, it doesn't matter what comes after it. The manufacturer may provide a case drain flow and pressure spec and you could test it and see.

    rebuild hydraulic breaker

    Once you discharge the nitrogen, they aren't dangerous. Each brand has its little qwerks. The easiest hammers to work on are NPKs.

    Best excavator to buy

    Hi Jeremy, Did it all of a sudden start this or is this a new to you machine? Sounds like your pump is going out. First thing i would do is let the machine sit overnight and before starting it pull the bolt on lid off of the hydraulic tank (not retrun filter lid, the other one)and pull the...

    Cat 320cl hammer/breaker

    For hard rocks you want impact power. NPK GH12 would be a good fit for a 320 and they are one of the easiest hammers to setup as they don't require accumulators and are not backpressure sensitive. NPK are expensive but you can rebuild the hammers instead of replacing as you would with other...

    Need a dipstick tube for expansion style dipstick

    Hello guys, Really hoping someone can provide some help here. I need to install a locking style dipstick on a machine and think that the old expansion style "T" handle would work best. I can find them all over the place up to 84" length which would work well. The problem is I cant find a...

    Rock Hammers

    If you want a cheap hammer to get through a job or two there are many out there to fit the bill. If you want a quality hammer than can be repaired for 20+ years than NPK is the way to go. Having the piston captured between the sleeves and being able to replace inner parts when an operator does...

    Hammer Issues

    D5GDevo- The plug that is leaking is called a drain passage. It provides a tell tale when the upper seals have blown out which yours have. The hammers are not difficult to disassemble if you have a 1" impact to remove reinstall the tie rods and you will need to use a small port-a-power to remove...

    Hammers

    Great choice, they will last a good while and when a rebuild is needed they are one of the only hammers on the market that are completely re-buildable.

    hydraulic hammer identification

    As long as you are sure its hydraulic oil and not grease separation then the hammer needs a reseal. Most guys would run it until it quits and buy another before performing a reseal on an older hammer like that one.

    One for the Komatsu men

    I'd lean toward the pump as well. Also there are usually inlet screens in the banjo bolt on the ppc valves, check it and see if there is material blocking flow.

    Hydraulic Hammer install kit

    I prefer npk kits especially for a machine like that. They are pricey and they may not have the kits ready to go for a dash 5, but they have manually adjusted reliefs which I like and the best product support I've ever seen or heard about. I would advise against hkx, I've installed around 20 of...

    Galion 150 Refurbish

    One of our customers has two 150fa's. We all hate working on them lol. One has been torn down in our shop for close to a year now, if it's not parts availability issues it's the customer not returning our calls. Damn those control valves!

    Best grease?

    One of my customers uses castrol pyro plex gold. That **** is like antiseeze and as much as you clean it off your clothes it gets all over, must be some good stuff and they say it worked best of the greases they tested.

    Lube skids- anyone use them?

    Sorry should have been a little more clear. Between shop and field(we are a crew of 8 field techs, no dedicated shop techs) we do 8-10 services per month. However the brass are on a big push to sell more pm agreements and they just greatly expanded our rental fleet. To top that every tier 4...

    Lube skids- anyone use them?

    Trailer would be great, however with or without a trailer we are still held to the same gvw. Tool_king: I work for a dealer in Southern California. AndrewC: I've made the suggestion of simply making small dollies for our 55g drums and a pencil pump but that too has fallen on deaf ears.

    Lube skids- anyone use them?

    Hey everyone, My company took away our lube truck and shipped it to another branch out of state back in April, they haven't used it since and we have been dying without it. They won't pay to ship it back to us and won't buy a lube truck. I was wondering if anyone has used a lube skid. It...
