Checking the components
Stem
Check the sliding surface for scorings and/or scratches.
These scorings can be eliminated by rubbing them with wet sandpaper (grain 1).
If the scorings are deep, replace the stem.
Use a dial gauge to check that the stem bending is below the limit value.
If over the value, replace the stem.

A BENT STEM SHOULD NEVER BE STRAIGHTENED BECAUSE ITS STRUCTURE WOULD BE
WEAKENED AND USING THE VEHICLE MAY BECOME DANGEROUS.
