    fitting a Cross hydraulic pump to a 130 TD5

    Hi Guys,

    I am getting MR to fit a Cross 40 PO 18 hydraulic pump to my ute.
    It will be driving a log splitter. I was wondering if i need to fit an oil cooler to the gearbox as it will be running for hours at a time.
    I would appreciate any opinions. Warren is not in today so I was unable to ask him direct.

    Id be fitting a "happy" hyd pump not a "cross" 1!! Now for some sensible stuff.......... Given that you intend to run it for hours stationary a cooler would not be out of place I think. Ashcroft do a kit for the gearbox. Also a cooler in the splitter lines is an idea too. Hyd oil gets hot under heavy usage All machinery with hyd s have a cooler of some sort fitted.
    Cheers Scott

    I have a Speeco 10.5 hp logsplitter and after working it for a couple of hours hard I can barely place my hand on the hydraulic tank. I recon that some form cooling would be quite essential, I just go for a beer and let it cool.

    Just an update on this. The hydraulics are all fitted and yesterday I bust a ute load of timber. Once I am certain that all is good with the splitter I will paint it.
    I only have one small issue and that is holding the RPM at 2500. At the moment I have a lump of timber holding the throttle down and the motor bogs down when busting big iron bark logs. I am thinking I might get the cruise control modified so that it can throttle up when under heavy load.
    Does anyone have a better suggestion.
    Next is a hydraulic winch.

    Firstly the cruise control uses a sensor in the swivels to detect speed. Unless you install a secondary sensor inside the gearbox somehow and change over when using the hydraulic pump you wont achieve your purpose.

    Secondly, don't all Australian R380 already have a cooler pipe running along the chassis and back to the box which uses the rail as a heat sink. It should be relatively easy to add an extension to connect a transmission cooler element.

    You won't find me on: faceplant; Scipe; Infragam; LumpedIn; ShapCnat or Twitting. I'm just not that interesting.

    That's a bummer about the cruise control.
    Yes you are correct about the cooler line. MR automotive suggested I trial it first before adding extra coolers. At this point I think it may be ok. Still early though to say for sure.

    I wonder if you could fit some sort of hall effect sensor on your crank pulley and switch over from the wheel sensor when pumping.

    Many after market cruise control units fit a magnet + sensor on a prop shaft for speed determination. Perhaps this would do the same with the engine crank.

    You'd have to confirm the sensor type (or even use the same part) and then the cruise control may do what you want.

    I just called Auto Strata and the guy said he was 99% certain they could do something. He needed to talk to the bossman who wasn't in. Plus they are packing up for Christmas so bad timing. I will call them in the new year.

    Might be easier to fit a simple hand throttle rather than modifying a cruise control.
    Must be a hell of a log splitter.

    A hand throttle will be little better (if any better at all) than the log on the accelerator he's already using.

    Back in the days when PTO drives were common optional extras, the engines were fitted with an engine governor that would increase the throttle when the engine came under load and would throttle back when the load came off again. Wayne is attempting to do the same function using the cruise control. I admire his effort although it will need modification to work.
