Many thanks for the video and help. Finally put the new o-rings back in, and re-assembled the machine. Cost $7-00 US. The Home Depot quoted me $450-00 to repair, more than a new tool.
your opinion about reliability of mechanics at Hitachi compared to other firms Bosch MAKITA DEWALT as well as the degree of difficulty in the manufacture of repair
dear friend ,may be you can show how too mounting back, may be have small things about we must to now during collecting. thanks. i talking about pneumatic side.
I use it about once a month for 10 years. The local repair company claimed it was the crank. But I opened it and every thing looks and works great. Just the hammer action feels like the hammer is only just touching the bit. More a vibration at the bit than a hammer action.

Can you tell me why the hammer action doesn't work. All parts look good, crank spins, but no hammer.

Its flat. Not much oil. I ordered o rings. How much grease inside? pistons/hammer crank area?
