    Hitachi EX120-2 Swing motor seal

    No chunks, just water oil grease. all cleaned up now and ready to go. Seal is working and keeping the gear oil out of the swing gear lower assembly. very nice.

    Hitachi EX120-2 Swing motor seal

    Will do. Thanks, got another suggestion to fish a rope around and drag a towel around to clean it out. I will try that.

    Hitachi EX120-2 Swing motor seal

    There was lots of gunk /oil/ water. 2 inches deep. any trick to cleaning the emulsion out. a drain hole is not obvious. I have been unable to google a repair/maintenance manual for my machine, any hints on where to get one? I want to keep the routine maintenance going properly. Thanks

    Here is a picture with the swing motor assembly removed. there is a 2 inch deep mixture of gear oil/grease/water. 1 and 1/2 inch of emulsion and 1/2 inch of water. Any tricks to cleaning it out other than pressure washer? is there a drain somewhere that I can not see? Thanks

    60.00 dollars for a new seal and I should be back in business. Very cool. This is a great forum. Thanks for all the info.

    Got the swing motor off with an impact gun and all looked good except the seal. 60.00 dollars and I should be back in business. Very cool. This is a great forum.

    A stronger impact and all the bolts are off today, swing motor is out. now on to getting at the seal. Hope there is a part number on it for re ordering. Thanks for the help with the ideas.

    Will the lock tight regain its holding strength after the bolt cools down again? Do I have to do the removing at the high temp right away? Thanks
