Found the water pump on my DB885 is about to send the fan through the radiator while doing an end-of-season inspection, general clean-up and service. The correct single groove pulley version doesn't look to be available here, although Parts ASAP shows one. Ebay, Amazon, Cross Creek, Reliable, etc. all have one. The price ranges from ~$80 to nearly $300 for new. "Generic" seems to be the only source and not a one has a customer review. I try not to shop price only but when the exact same picture is used by a multiple vendors with a broad range in price . . . I gotta wonder if the the mark up is the only difference, not the part. Same one year warranty too. If someone has a trustworthy favorite go-to source for parts for old tractors, I'm all ears. Might check into letting the local NAPA round one up so when it fails I don't have to quibble with a faceless internet vendor.
