    D4H Transmission overheat issues - 8200 SMU 8PJ

    Similar problem I come across on a D6H was TC getting hot very quick while working. Machine would push well and no indication of slipping. TC outlet relief was low, after a lot of checks I found some of the o-rings were damaged in the control valve oil feed tubes and the tubes running to the...

    Line Boring Systems

    I use a B&D unit EV-2500-s type, have a look on the net for the different set ups, most manufactures have got demo videos. Again like Nige has pointed out you need to know what unit will suit your job requirements.

    Line Boring Systems

    I think Tomv uses a York boring machine (electric drive) and a Bore Repair System bore welder. Like Nige and RayF have said hydraulic drive has a lot more power, I suppose it all depends on how much $ you want to invest into the initial set up. Small to mid size work then electric drive will...

    Line Boring Systems

    I bought a Bore Repair System set up, for the price I paid I can't fault it, also you can upgrade as you want. I had work for a line borer but could not get anyone to do it, I had no previous experience, apart from watching a guy use line boring equipment a few times, so I thought I would give...

    Had a Kubota engine which developed oil leaks and a lot of blow-by through the dipstick enough to blow the dipstick out. The breather on top of the rocker cover was not working due to some mud wasps had filled the release valve with mud, they got in through about a 3/16" hole in top of the...

    D6R Dies Under Load or turning

    Will the engine die while using the implements? The same pump drives both steering and implements. Watching the videos, when the steering is used the engine just stalls. While in a transmission stall the engine drops about 800 Rpm > also trans & engine temps seem normal.

    How stupid is this

    Back to the original post 'Zero tow policy' Sound like someone had an issue with a light vehicle towing something, so instead of sorting out that issue, they disengage their brain and make a policy to blanket cover every towing situation, sit back and be proud. Then engage brain and...

    D6T running rough, now won't start. Thinking HEUI pump.

    We had a similar problem on a D6T a new set of injectors was fitted, ran ok for a few hours then same thing running rough and misfiring. If you got access to Cat info check REHS3819 gives the procedure for troubleshooting and cleaning the oil rail system. We found that the heui pump was worn...

    CAT308E CR Possible cracks in boom

    Sorry I don't have any photos. The reason I brought it up was these machines we have are used by pipe crews laying pipes, and there is a possibility of it snapping while lifting pipes etc. with guys in close proximity.

    CAT308E CR Possible cracks in boom

    Bit of info: Some CAT308E CR excavators may have cracks in the boom around the stick cylinder rear mounts on top of the boom, check with your CAT dealer, they carried out a crack test on four of the 308E excavators for a company I contract to and all four had cracks, clean off the paint along...

    Lessons learned

    Don't expect an operator to stop a machine just because of a blown hydraulic hose (988B) had one one travel to me rather than call me up, drained most of the tank.

    some work pictures

    I found that explaining to the customer what the job requires before hand, rather than surprise them after the job is completed, that the need for special tools is required. Some think it's all done magically.

    PC300-8 do not start in the morning

    I'm not familiar with this machines problems, what I've been told is that it is low on power and Komatsu have been out to check it, finding a possible injector fault. I was given a box of new injectors and a workshop manual late on Friday to do the job Saturday morning. I don't think it had a...

    PC300-8 do not start in the morning

    Bit of info, changed a set of injectors in a PC300-8 today, as it was I had a workshop manual. To remove the injectors first you have to remove the high pressure tubes that runs through the cylinder head to each injector, remove the line from the common rail to each injector, then remove the...

    Check all the hoses and connections from the fuel tank to the pump, the banjo fittings can get blocked causing a low pressure fault.

    Just purchased a D6-9U with low hours, looking for suggestions

    Looking at the paint work around tracks and frame the hours could well be original, great machine.
