Yes, it's a 25mm pin with a hole for grease fittings, and modified to be secured with a nut. Sure. I'll do that.

One of the brackets connecting the boom and arm has bent. The pin shaft broke and flew off somewhere. If you compare it with major mini excavators, you can see the difference. They have wedge-shaped reinforcement structures welded between the brackets. I decided to grind down the elongated...

I don't understand the intent of your question. I'm trying to identify and address issues with my mini-X. If there were no issues, the boom swing bracket or pinion wouldn't have broken.

Then the key would also suffer less damage. I'm not sure exactly how much force "sufficient force" refers to, but it's normal for it to be impossible to move with just human strength. The motor itself has a slight backlash, but it's negligible.

Most of the swing slope on my mini-X was due to the keyway. This photo was taken before installing the cushion valve. When I replaced the broken pinion, I installed a new keyway. Of course, there was almost no slope. However, a month later, it reverted back to its previous state. My conclusion...

As you know, it's best to position the RVs as close to the motor as possible for optimal performance. In theory, connecting the RVs to the motor using metal piping helps minimize pressure drop. In small equipment operating at 2400 psi, hose connections may not present issues. However, one may...

It appears to be a flange-type counterbalance valve which have O-rings for sealing. BM5 Series Orbit Hydraulic Motor Counter Balance Valve Unfortunately, my drive motor doesn't have threaded holes, so installation would be difficult, and it seems like modification is necessary. Freewheel of...

I don't think you need to follow these pressure values. It's more appropriate to find the suitable pressure through actual testing. I haven't even measured the pressure of the shock RVs. Testing on a slope is to ensure that the cushion valve is properly set. Since this document is about Kubota...

Thank you. I'm glad I found this forum. I didn't have anyone to discuss things with in my country, so it's nice to have this platform. Before hitting 60 hours of operation, the pinion broke. Although backlash was a concern, most of the play stemmed from a damaged shaft key, consistently...

Thank you. I'm glad I could help you. I recommend that you also perform the attached tests for your safety.

Hi, I'm new to here. I bought the Leking KV128 last year, so it's been almost a year now. Please bear with me if my English isn't perfect. I'm Korean, BTW. The model I purchased seems to have been discontinued due to too many issues. The swing pinion and boom swing bracket broke, and I had to...
