Gap between bb an left crank arm
So I just purchased a new set of crank arms and attempted to install them. I have a square taper bb spindle, btw. So I installed the right side crank without any problems, but when it came time to install the left side crank arm it wouldn't slide all the way onto the spindle, leaving a gap between the crank and the bb as well as a portion of the spindle exposed. This doesn't look right at all I mean it definitely looks like all types of dirt and stuff can get in between, but I'm confused at how easily the other side went on. What are some possible problems and/or solutions.
Thanks in advance
Also, sorry I just realized that this should have gone in the mechanic forum. Still new to the site so I hope it's not too big of a deal.
Nothing abnormal, there will normally be a small to average-sized gap. you can twirl up a wet paper towel to get the area clean without taking it apart.
Ok, cool. Just freaking out and expecting the worst since it's my first build.
