Just rebuilding a 280 pro 07 model, got a question , there,s two o-rings on the output shaft, do these both go in from the outside after the bearing, i know the 1.5mm one sits in the spacer but its the 2mm o-ring i,m not sure on. Any help apreciated. should have paid more attention when i pulled it appart.

I put both on the outside. As you say the 1.5mm one fits in the bush resess and put the 2mm one on the shaft first next to the bearing. the parts drawing shows it this way so I copied that!
