Lube question. so i've replaced a number of idler pulleys on my zero turn, a few on my pickup. never seen a grease serviceable idler pulley, all sealed.
asked an engineer friend who designed pulleys, and a good small engine guy why so...they both said sealed bearings are superior & will outlast grease serviceable, due to contaminants, etc.
your take? do you agree w/engineers & mechanics above based your own experience? btw, i'm glad to have grease serviceable mower spindles & front end zerks on my old pick up. thx in advance
