It’s one of the most common problems with crankshaws, and it can sometimes be frustrating to get the job done correctly.
In this article, we’ll go over how to fix a crankshelf that doesn’t have enough tension on the bearing, and what to do if the problem persists.
Remove the bearing and screw it in a way that can safely hold the crank in place.
If the bearing is already loose or damaged, you can use a screwdriver to gently loosen it, then re-install the bearing.
This will help prevent any more stress from the bearings from breaking off.2.
Make sure the bearing has sufficient tension on it.
You can do this by pulling the bearing tight against the crankshub, which can feel the bearing pull.
This forces the bearing to push the crank through the crank’s hub, which is the same way that the crank is pulled through the cranking gear.3.
Remove and replace the bearing’s bearing with a new one.
You’ll want to do this so the bearing can be reused.4.
Clean the bearing in a vacuum cleaner.
You may have to get your hands a little dirty, but that’s OK.
Just clean the bearing with some rubbing alcohol, a tissue, or a paper towel.5.
Repeat the above steps until the bearing doesn’t need any additional attention.
You may be able to get by with some basic care at this point.
It’s easy to forget about the bearing after a while, and you might even need to re-attach it to a cranking wheel or even to a drive shaft.
The best thing you can do is let it cool off, then inspect it with a light to see if there’s any damage to the bearing or the drive gear.
This should be the case regardless of the bearing that was replaced.
