If the tool is new I would call the company that you purchased it from and see if they will give you another one or let you send it in to be repaired. When you say its just rotating does it hammer hard or does it sound like its hammering real quick like a chattering? Does the air motor stall out and just blow air? If sending it back is not a option I would unscrew the four allens off the clutch housing and inspect the clutch to see if anything is broken. If all else fails give A-1 Hydraulics a call at 770-907-0013 and we should be able to help you out

If you are still looking for this part I would call power tool repair at 330-630-0022 and order that part number. From the breakdown it seems you have the correct part number

If debris has been entering tool over time, the vaines will not make good contact to cyl. wall. Flush out gun with kerosine or diesel fuel to clean interior of the gun. If dirty, the first flush will be very dark and every flush after that will become more clear. After good cleaning/flush, add tool oil and retest tool. If tool begins to hit but not full power, you may have to open tool and remove scratches from the vaines. Make sure that you use the largest quick connect fitting possible. Sometimes the tool will loose power if you are using 1/4 inch connections and the vanes are not in good shape. Good luck

You should be able to adjust the pressure switch inside. There should be a screw that you can turn in and out to adjust the pressure. By turning the screw out, it should lower the pressure.

wouldnt be surprized if its pressed together as if theres plenty of oil in there,they dont normally need stripping right down
