Doug, do the seals have more stiction when they age? do they shrink?, what makes them go bad? Do they look different than new ones other than being clean? With your knowledge and experience I never doubt your answers, sorry if I post something by mistake, my BAD.
No, about 12 to 14 years ago HWH used a type seal that after years of operation lost its "glide" ability. This is the internal top seal. It was tight enough to keep the Cylinder from going that last 2 to 6 inches. HWH found the problem and made the seals out of a different material. The problem still crops up on newer cylinders but is VERY rare. I have not seen one on less than 4 year old HWH system. That is why uninformedpeople on the Internet keep stating all these silly lube fixes. That works for a little while but the problem comes back. The ONLY PERMANENT fix is rebuild or replace. The way to tell is simple. When the jack stops, you should be able to use your hand with very little force and it will retract. IF it does NOT, fix or replace the cylinder. IF it retracts with hand replace the springs. Doug
