Are you getting it out and about on jobs or still fettling bits on it? Either way probably not going to go wrong at that price point.
I've not yet had totally the right job for it. It's been handy about the yard, done a few gate post holes with it and some scratching about but no big digging jobs yet.
I've replaced the boom wear pads (big difference), new pins in the hitch linkage and turned some bushes out of some nylon I had for now. Going to get a mate to turn down some 50mm I have to 45.3mm, this will account for all the wear in the hitch ears and the tipping link (non bushed). It doesn't really need this though as with the new plastic bush in the dipper end and enough shims the hitch is nearly as tight as new, tighter than any hire machine I've driven for sure. I built up the hitch jaw with some half pipe and weld so now the buckets are tight too- again, massive difference.
The slew rams I did new pins in and shimmed which took maybe 75% of the play out. I will need to to one slew ram mount bush, which has worn due to the back actor always being used on the right. I've ordered some 90mm Oilon to play with, they are easy enough to get to if it doesn't last but I have high hopes.
Basically it's useable now and overall in very good condition. All I've had to do is wear related stuff, touch wood, everything else seems good.
The maion problem I have is that I seem to be quicker on the 3 tonner for most scratching about jobs! But I'm still learning.
