Have been having issues all winter, espec in DEC, due to the factory grease not being able to withstand the subfreezing temperatures. Took apart and lubed it up last night with Jet-Lube Arctic. I wish I could say it purs like a kitten but the CG5 mounts are just noisy for some reason. Anyways, it's much smoother now. I'll let ya know how the grease holds up!
I found that Goo Gone and a toothbrush were able to cut through the old grease (that had the consistency and viscosity of old rubber cement) much better than alcohol. Another rainy day I'll do the RA motor...
