My D69u was stuck in some muck for a month or two.....I got it out and doing greasing and lubing things.....the lower rollers have plugs rather than the grease type fittings. Does this mean the rollers are self sealed? Is there a way to grease of lube these? fred
they are supposed to be lifetime lubed--but you can pull the plug and refill them up to level. There is a special fill rod that can be inserted to get new oil to the far side of the roller
