HD9B Garwood Hydraulic Cylinder Rebuild

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all,

It's time to rebuild our HD9B GarWood blade's 2 hydraulic cylinders. Both are leaking internally so the front blade slowly drops on its own. One can actually hear the fluid moving past the internal hydraulic cylinder seals when the blade falls!

I'm clear on the process of replacing the cylinder seals, but I've not done it before. Are seal kits still available for these very old cylinders? Anyone know of a business in California that I may simply take the 2 cylinders to for a reasonable rebuild?

Thanks in advance for your feedback.

Jim

	Hard to tell but looks like those would be old style and have V ring packing and cylinder piston V rings also . Not the latest type with square ring piston O ring type . A hyd shop should have or be able to get what you need , the hard part is paying $150a hour or so for them to rebuild them

	I needed internal ring and exterior gland to cylinder O rings for a cylinder off backhoe , went to shop and brought the end gland with me ad asked for the parts . Counter guy said it would be $45 minimum charge for shop to remove the old parts to match what was needed . I took out my pocket knife , pulled the rings laid them on the counter and said match these - $ 6.00 for the parts .

	Paso Bearing and Hydraulic has always found what I needed. Looking on line I see a second location for them in Atascadero. There shop rate labor is rather high so see how much you can do yourself. It seems each cylinder has a new trick I need to learn, but not rocket science. Hopefully you can get the rod out of the cylinder bore. Take that to town so they measure the parts then its their mistake if they get the wrong parts. If the piston needs off the rod, could well need bigger wrenches than you might have. As well as impact can do wonders on those nuts. Or maybe you have one inch drive sockets to 3 inch already. I don't have Snap-0n wrench on the ranch but know a trick or 2 and some tested Chinnessem wrench's.

	Guys, thanks so much for the input. Yes, I've got the necessary tools to pull the rod/piston assemblies from each cylinder and leave the outer cylinders on the dozer. That's actually a lot easier than pulling the complete assemblies from each side and transporting them. Will the hydraulic folks refurb the rod/piston assemblies (meaning replace all seals) in this state or will they push for me to bring in the entire assemblies including outer cylinders? Thanks again. Jim

	I think I had them do a ram for me, but not sure anymore. I am a do it myself guy generally. You will have to talk to Paso bearing and see how they want to do things. My last dealing was 5 years ago. My main lifting device is JD 1250 tractor loader. A Japanese Yanmar built tractor. The loader is JD. I bought JD parts to hopefully speed up the job. Only 2 choices and pictures looked like it had to be only the one. So off I go with $50 to $100 seal kit. Took things apart nothing fit. Took all the old seals, JD had the other seal kit in stock, IT WAS WRONG too. So off to Paso bearing. Five minutes of measuring and looking up numbers. They had the pieces in stock. Ten dollars latter I walk out with the right parts. Put that one together, with total success. But you don't get that lucky every time.
