Couple of factors here. The 8010 and 2388 are almost entirely different machines (NH in origin) and the 8010 has higher throughput. You will have to replace components and address certain areas sooner or with greater frequency with the higher throughput rate, but in addition, there are areas such as this that are built a bit on the lighter side. Other areas you'll want to put your eyes on would be grain tank auger bottoms; unloader elbow and tubes; clean grain (and to lesser extent tailings) bottom cross auger troughs; elevator boot and head; fountain auger/tube (probably already done); chopper bearings; various belt idlers and bushings; feeder floor - these are just areas to call special attention to for wear in addition to your normal inspection of the processing components of the machine.
