[QUOTE="500K_773, post: 236, member: 33"] It's been awhile since I've rebuilt any hydraulic cylinders, but remember it was pretty simple. IMHO, It will be easier and less messy if you take the cylinder off the machine. It is a good idea, but not necessary to buy some plugs and caps for the fittings and hoses to prevent leakage and protect the threads on the fittings. The hydraulic fittings should have a size stamped on them, ie. -12 is a 3/4” fitting and -8 is a 1/2” fitting (note the number is a 1/16” increment). A spanner wrench will probably be needed to unscrew the cap. It is important to check the rod for scoring and nicks that may tear the new seals. Minor damage is not too bad and should work well for awhile, but severe scoring should be addressed. I don't know how much your Bobcat dealer would charge for a new rod, if needed, but a good hydraulic shop could probably build you one cheaper. Use care during reassembly with the new o-rings and lubricate well. Keep everything clean, any dirt or metal pieces will end up in your hydraulic system. If you plan on changing your hydraulic filter after repairs, it is best to test everything first in case you have to tear it apart again to fix a leak. I don't have any experience with Bobcat axle seals, so I'll leave that for someone else. [/QUOTE]
