I forgot to oil the water pump in my central heating system. I oiled it in 2006, and then I completely forgot, until...
2 days ago, my wife says "what is that squealing noise"
we hunted around, finally tracked it down to the pump: oh no!! I forgot to oil it for 3 years!!! so first i oiled the 3 points with 10w30. that quieted it for a while. next day started squealing again. more 10w30 added. overfilled bearings leaking oil on floor. still squealing, so i opened a can of MolySlip MoS2 suspension, took a 5 cc. syringe, and forced the whole contents down the three oiling ports, especially the main bearing port.
lo, and behold... squealing gone now, for 2 days, bearings sound just like normal, everything works great. MoS2 must have repaired the abraded metal surface, or done something good.
at least it saved me an expensive repair job.
