stihl bg blower crankshaft problem

[thecaptain]

been using my stihl bg56 blower for ages then suddenly after starting it up it made a crunching rattle noise, took it apart and noticed where the crankshaft connects to the turny bit with needle roller bearings, its missing a narrow sacer so you can see the needle bearings, my guess is the spacer exploded into pieces

 

can I just buy replacements or do I need to by a complete crank shaft kit? does anyone here have something I can use? no other damaged caused as far as I can see

 

thanks in advance

One of ours broke a crank , I picked up a case with crank on ebay .
