A few years ago my 1026R was due for its first 50hr service. I couldn't get the plug out. In fact I stripped it bad. Not wanting the mess with it, thinking this this first service was important, and having a bit of work to do that summer, I had the dealership come get it, service it, and bring it back. Now it's due for its 200hr service and I look under and the same stripped plug is there. Shame on me for not noticing it earlier.
I was worried they had only changed the motor oil but when they looked me up we saw I had paid for a filter and fluid, and then said they probably just drained the hydraulic fluid from the filter without messing with the plug!! I could've done that myself. So question is, is that ok? Can I do an effective hydraulic oil change by just draining it when I remove the fliter?
