Help needed on Liebherr Crawler Crane LR 13000 #42146

The red pins visible on page 71 are so close to the grey plates attached in step 85 that they actually touch, when the structures is rotating. It seems to me that they serve no purpose, but to create friction and uneven turning. Am I missing something here? Or did I put it together wrong? submitted by /u/realinstanick [link] [comments]
