The guide roller bolt locates the guide roller within the cylinder.
If you ever wonder what the little hex head bolt was for that goes on the left side of the cylinder now you know.
Don’t remove it out of curiosity.
Although this bolt rarely wears out it is sometimes lost during disassembly and should be replaced with the correct item.
