I decided to grease all the backhoe zerks on my Kubota bx24 TLB the other day and noticed the stainless steel pistons/shafts on the backhoe were a little dry looking. Hadn't used the backhoe sine last fall and it was not on during the recent 100 hour service at the dealer. Decided to apply a small dab of the grease I used for the fittings and smearedit on with a cloth. A few days, later, there is a layer of dust/debris on the shafts. Did I make a mistake in "oiling the shafts"? Should I clean them now? What is the usual maintenance of these?
