Importing and modifying a new mini excavator from China

   / Importing and modifying a new mini excavator from China #1,463  
Thanks for the info. I will start on those tonight.
You may want to check for yourself since it's a different model, mine also has a swing boom with no pilot controls. There were three male zirks I didn't replace too. Also, the cylinders were all M8 and many were weak threads. I suggest tack welding all the zirks on the cylinders.

Here's a service manual for the H12. If anyone has found for other models please post. Starting on page 44 (pdf p.46) is where the BOM starts if you are trying to build a parts manual.

Yes, there are several different kinds of zerks on these machines, plus you will benefit when changing some to angled zerks.

What I would do is remove the zerks you want to change, and measure the thread. Then buy the sizes you need. You can also get a zerk kit that has a variety of sizes.

Hi everyone. I’m new to the site, and joined because of this thread. I’m grateful for finding it be a new owner of a agt lh12r. I’ve definitely already learned a lot after a few days of reading all the posts here. And hope to add some of my own as time goes on

Thank you, I definitely have a lot of plans for it. Unfortunately winter is making them wait.

Yep, I’m in the same situation, mini is tucked away waiting on warmer weather. I want to add a hydraulic oil filter as the next mod/improvement.

I plan on doing the same with a full hydraulic oil change at the same time. I do plan on adding a few attachments over the winter so I’m ready for spring. One thing I do plan on working out over the winter is some sort of quick tach extension for the blade to help stabilize during tougher digging conditions.

Opposite here. I need the fall/winter/spring moisture to properly dig and compact. My machine is way up the creek, preparing to grab/pull/cut a bunch of fallen trees and branches for a winter burn pile.
