RE: HP 41 Repair for inexperienced owner
Common opinion seems to be that WD40 is not good for this sort of aged plastic. If you have DeOxIT on hand that might serve as a lubricant. A drop of isopropyl alcohol might serve the same purpose. Use of a socket tool would be far better than pliers since it would minimize side forces on the post that could lead to cracks. If resistance seems too great, loosen and tighten to break any adhesive force. In the end you just have to trust to your own feel as as to when the resistance is too great to overcome. The Calculator Store in Spain does have some repair parts, but maybe not for this lower post arrangement.
