    Some Line Boring Pics

    I work in power plants.A few years ago we did a power uprate on a high pressure steam rotor in a nuclear power station.The machine used was very similar to the one in the video link.I was a bit surprised to see that rotor being turned in an open bearing saddle with just an oil film to spin on.I...

    Komatsu PC50uu-1 hydraulic problem

    If the pump is checking out as good,it should build the same pressure 3100 psi ,assuming the relief valves are set the same,when hooked up to either the 6 spool section,or 3 spool section.Id hook it to the 6 spool,check psi,then swap reliefs again and check psi.If everything is pretty close on...

    Komatsu PC50uu-1 hydraulic problem

    Make sure there is nothing between the pump output and the weak valve section.maybe you missed a valve somewhere?Are there any valves built into that pump?Some have what looks like just a plug,but contain flow or relief valves built into the pump housing.If the problem swiched sides by switching...

    Komatsu PC50uu-1 hydraulic problem

    Sounds like that section of the pump is worn out.You should be able to replace just that section if you can find the parts.You would likely need a new set of gears,gear housing,wear plates and a seal kit.If you happen to be lucky enought to have a pump that the gear section can be flipped...

    Detroit 8V71

    There is no place to bleed fuel on a detroit 2stroke.If you are changing filters on one,its best to do it on a warm engine,remove the old filter,replace with a new one,fill the filter with fuel,reinstall.When ready to start set the engine at 50% throttle,and hit the starter,it will sputter a...

    Komatsu PC50uu-1 hydraulic problem

    I think its worth a shot swapping lines around,a few adaptors should be easy to adapt the different hose sizes.It would give you a much better idea where the trouble lies.Check the pressures on all 3 pumps before swapping hoses around.The machine does not need to be throttled up just to see how...

    sick 471 detroit

    It may have been Delvac 1240,its been a few years.All i know is we had no valve issues using that compared to the Texaco Ursa 40 that we were originally told to use.

    Komatsu PC50uu-1 hydraulic problem

    Check your pressure on the 6 spool bank,if thats where it should be,try swapping the pressure lines on the 2 valve banks if possible.If the problem switches valve banks,then the pump is bad,if it stays the same,the relief is weak.

    sick 471 detroit

    I,ve run Detroits for years,id put my money on either a striped blower drive shaft,or blower drive coupling.They can be striped,but still turn just enough to keep the engine going,but blow black smoke like crazy.Blower shaft and drive are both easy fixes,and a very common wear item on those...

    HELP with identification of Detroit Diesel

    Thats a V53 engine for sure,V71 and V92 valve covers arent held on like the V53 is.The id tag hold is still on the valve cover,you can see the bent lip on it in the upper right corner of your picture,but it looks like the id insert is gone.

    Looking at a 580CK, would like some advice

    I resealed all the loader cylinders last year.Ive done lots of cylinders and had never needed a tool to install seals untill i did this one. The ucups on mine are very thick and stiff,i couldn't even get them compressed enough to get them started in the gland,yours might be very different...

    Looking at a 580CK, would like some advice

    I,ve done hydraulics for years.You will find it well worth the money if you buy a tool for installing the ucup rod seals,without the tool its nearly impossible to put them in the cylinder gland.I cant remember who makes them,but i believe them make 2 different sizes,i think i used the larger...

    spool valve

    Im not so sure thats a Commercial Shearing valve.My Case 530 has a C/S V20 series valve,it looks nothing like that one.Of all the valves i've run across it might possibly be a Cessna valve. As for seals,i'd look on the internet,and local phone book,most larger citys will have a company that...

    Gradall with detroit 6v53

    From what i can recall about the govenors on the detroits,the two most common differ greatly in how they work,an automotive type will not stay at a constant rpm,pushing into a swell rpms will drop,coasting down the backside rpms will increase,posibly very high,the marine type governor pretty...

    Looking for Diesel Engine Making 300 HP at 800-1000 RPM

    I don't know much about locomotives,but i see no reason why you couldn't adapt a modern,more popular engine,such as a small Cat,Cummins,Detroit,or whatever by putting a reduction gear on the engine.A turbo 671 detroit would easily put you in the 300 +HP range with a 2:1 reduction gear it would...

    Case 580b CK Hoe quit swinging

    To torque that to exactly 1000ftlbs you need either a 3/4"torque wrench and a torque multiplier,or a Hytorq setup.If you weigh about 200lbs,and use 5' of pipe,you should come pretty close by standing on it.:D

    Gradall with detroit 6v53

    The 6/53 is not a bad engine,but for pushing a barge,it wouldn't be at the top of my list.Its a very noisy engine,needs high revs to make power,it was never as popular as the 71 or 92 series detroits,therefore parts may be harder to find if needed. I think if you can find the governor...

    Gradall with detroit 6v53

    24'x60' is a pretty sizable boat to push with a 6/53.Load that thing up with aggregates and your pushing alot of tonnage.Speaking from experience running boats,and towing,the more horsepower ,prop size,and reduction,the better your setup will handle.Not saying a 6/53 wont do the job,but handling...

    Gradall with detroit 6v53

    I'm not sure what size that 6/53 would have,but i'm pretty certain Twin Disc makes adaptor plates for its transmissions,i do know detroits can be set up to run either direction,but a twin disc cant.If you did have a non standard rotation engine,a borg warner 73 series,if you can find one,or the...
