I would like to give no stars because I still have not received my order. It has been almost a month. I’m going to wait another week or two and then demand a refund.
The slewing gear upgrade is a must have, the inner bearing inside the gear vs the friction plate there isn't any comparison in the two, I'm able to dig more precisely and lift more with the new slewing ring all the sloppy excavator movement is gone with the new setup. I have the hydraulic conversion and I put over 250 hours on the original gear and this new setup should last forever, I'm very pleased with all the products I've purchased from extreemrc. Thank you guys!
Nice and smooth and much better than the original one. Should last longer than the machine itself. I love it. Thank you guys at extreme.
Just received knew metal slew rotation gear for my huina 580 quality and workmanship looks good will be so much easier on the rotation motor.looking forward to installing it. (Thanks)
