Catching up on winter maintenance. One weak point on the 301.7 we have noticed is the main bucket pin at the end of the boom. We carry a spare pin, in addition to spare pin retaining bolts, so we can swap the pin and get running again quickly. When we get the machine out of the field, we perform a pin and bushing change to ensure a proper fit and catch further problems, like broken bushings with this one.
As trailbuilders, we charge our small equipment with big task, so it is no surprise that we wear some parts out a bit faster than normal. It is important to keep our equipment in good order and well maintained as we often work on remote jobsites.
Is it how the thumb is mounted on the longer main pin with greater leverage, or just the constant stress we put the equipment through? Overall, it is a fairly simple fix, and the 301.7 has held up very well compared to many of the other excavators we have run in this size category. It's all part of doing what we do with these pieces of equipment to provide quality recreational opportunities while trying to keep our footprint small.
