Hydraulic piston replacement options?
|
Hi! I have a Homier 4x6 bandsaw, model MBS46/03111. My hydraulic piston leaks (and might have air inside?) allowing the
blade to drop down in little jerks rather than a smooth continuous slow
motion. Are these pistons serviceable or should I be looking for a
replacement? Any suggestions one where to get a replacement? I think I
had the same problem when I first bought the saw and got a replacement from Homier which is the one I am struggling with again now. Actually it has worked poorly for years and I'm just getting around to doing something about it after several recent frustrating uses.? I'm hoping there is a 3rd party
replacement I can get. Any suggestions?? |

开云体育You have any pictures? No idea what Hormier used for their cylinder, but I assume it’s the same as other China built and rebranded saws. If the cylinder is like my grizzly saw, also made in China, you disassemble the cylinder by removing the snap-ring on the packing gland on the rod end. Grizz doesn’t show a breakdown of the cylinder, and I haven’t had mine apart, but seals & o-rings are easy enough to measure. A call to Grizzly may be worthwhile, assuming it appears to be like your cylinder. They may sell kits or seals for them, but not list them, or they may be able to tell you what they are. ? Take a look here, and see if this looks like your Homier, or at least if the cylinder does: Pic attached is of my Grizzly saw. ? Bill From: 4x6bandsaw@... [mailto:4x6bandsaw@...]

开云体育Generally speaking, if you can get the cylinder apart, you should be able to rebuild it if they used standard seals and didn’t make them themselves. ? Robert Downs ? From: 4x6bandsaw@... [mailto:4x6bandsaw@...]

Be much easier to rebuild your cylinder than get a replacement which would have to be identical in length, both extended and compressed, for it to fit your standard mounts.??
I'm trying to figure what would cause it to move in jerks, would have to be hanging up in the bore then dropping so it might not be the seals, rather wear between piston and bore. If the bore is not damaged, then maybe the seals are too tight.? Could be swelled up in which case new std size might free it up.? Seal retailers have many different seals? both imperial and metric.? You can use a smaller diameter with the same cross-section stretched to fit which will fit a bit looser, or a metric instead of imperial etc..?? Let us know what you find on disassembly - jv |
