Sounds like you have a broken connecting rod. The easiest way to check for this is to remove the 4 cap head bolts holding the cylinder on and remove it. If the hammer piston comes off with the clinder you should be able to see the break. If that is ok you may have some stripped gears or a broken spindle somewhere. But I really think it is the connecting rod.

Brute hammer uses special grease sold as service kit. This kit contains enough grease to lube hammer and replacement bolts that hold springs along the bottom. Check www.toolpartsdirect.com for parts and kit. Remove the lower half (tube) of hammer, also remove three bolts that hold springs and remove assembly from tube. Wash out old grease. Grease will be oil-like only when hammer is very hot, otherwise grease is paste-like. Good luck.

SOURCE: I have the Neiko electric
I have seen many different brand names on this tool depending or retail outlet / where purchased, including Sears, however none of the sellers offer replacement parts or are much help when a problem arises. This tool is a Chinese copy of the Hitachi h65 and parts list for Hitachi hammer can be seen at www.toolpartsdirect.com and many other web sites found by google search ( hitachi h65, or hitachi h65 manual ). Instead of taking apart the lower end of the hammer (if hammer still functions ), just remove the oil fill compartment cover and the oil felt retainer ( or only the felt) and introduce light oil directly into hammer to flush out old oil / debris. After you are satisfied with lubrication of the hammer, clean felt with diesel fuel and re-install. The felt is a wick and transfers the oil to crank. Place the wick in proper place for crank to catch oil (or replace wick with hitachi part). If oil does not transfer, use lighter weight non detergent oil. If you still want to take hammer apart, (remember that no parts are available) you will need to take the rod off the crank by removing the side cover to easily pull the lower end. Good luck with your repair.
