Its not right, but it beats paying to have them re-chromed. Sometimes I repack the same cylinder several times a year. The wear rings can be tight, scrape them with a razor knife until they fit.
I finally bought the special tool to install that seal. The only seal you should have trouble with is inside if the cap. I buy 3 sets of everything and have them for next time. There are a few telltale signs that your hydraulic cylinder needs to be repacked: Difficulty lifting a load or moving a component (not moving as fast as its supposed to) Implements leaking down faster than normal Cylinder is leaking oil externally they can leak and still. Take the cap and the nut to a hydraulic shop, they can match all of your seals etc. There are multiple types of hydraulic cylinders but the process for checking and repacking them is generally the same. Once you have the nut off, remove the piston. I use a big adjustable wrench and a cheater.
With the rod still hooked to the eye, it will hold firm while you loosen the nut. Use a big pipe wrench to take off the nut(cap) from the barrel, or a cold chisel and hammer. Leave the end of the rod pinned in the eye if at all possible. On older stuff its usualy not worth fixing it "right". Its not too hard if the cylinder and rod are good.
My Case 580 backhoe repair manual recommended red. The hydraulic shop is a big help to decide.ĥ) It is very important to use more thread locker when you put the nut back on after replacing the seals. If there is a dent or ding in the casing or bent shaft it may be not worth fixing. I take mine to the local Les Schwab tire shop truck tire bay.Ĥ) Check the shaft and cylinder for dings, glazing etc and hone or use emry cloth to reduce or take it out. If you know someone with a 1" or 3/4" air impact driver, take it to them to loosen the nut.
They are typically set with thread locker liquid. A good shop will give you updated seals, wipers etc if the cylinder is 20 or 30 years old like mine.ģ) The nut on the end of the shaft is very hard to get off. Hopefully they will have all the seals, backer rings, wiper ring etc.
If there is a slot in the cylinder casing you might need to pull a keeper ring out to free the cap from the casing.Ģ) Take the rod and cap into a good local hydraulic repair or supply shop. Might need a spanner wrench- you can make your own. Here are some that might be helpful:ġ) Take the shaft out by disassembling the end.
