Backhoe Loader 75 & Backhoe 8 hydraulic cylinders

[markct]

i understand what you are saying about your time limited, but realy when rebuilding a cylinder half the work is taking the cylinder off the machine. rebuilding them sounds hi tech but its realy pretty straight forward as long as the rods are not pitted bad or bent etc. usualy its just a matter of putting in new soft parts and back to work you go, take them off and when ya get a few minutes in the evening take one apart and put the kit in it. on a backhoe this size it shouldnt be too big of a job. some larger cylinders on heavy equip have a nut on the rod thats torqued so much it takes 1 inch drive tools and huge sockets, but not on a machine this size. try it, im sure ya will find with a bit of practice they arnt as hard as it sounds, and not worth the money most hyd shops get just to install seals

All good points Mark...

In a similar vein, is there an aftermarket transmission/hydraulic oil I can use which is more readily available then the "Hygard" (sp?) 'Deere-recommended' lubricant? I want to change my hydraulic fluid and filter while I'm swapping out hoses and rebuilding cylinders.

I am sure there is, But I use the HyGaurd stuff-it is really competitively priced compared to any other name brand oil and my dealer is close...

im pretty sure many of the universal hytrans oils the farm stores sell say they meet the spec for jd, however i only run jd hygaurd in the reverser and transmission of my loader backhoe, its got all the right properties for the wet brakes and reverser clutches etc in there, some wet brakes will chatter with the non oem oils etc. i do run the generic hytrans in the hydraulic system tho, its a bit cheaper and more readily available, and thats the system you are topping off when you blow a hose etc. also the hydraulic system is pretty basic, just a gear pump, so there pretty tolerant of most any oil as long as its clean

Ditto to what KennyD said. As much as I feel that there's a "Pay for the Name" factor in JD pricing, when it comes to fluids, I'm not taking a chance! Glad you got the JDParts site happening for you.. It's an awesome resource! You really need to look into a CD Tech manuel for your unit. I got mine on E-Bay, (looks pretty, but probably a bootleg). I think JD does a great job on their manuels etc. ~Scotty
