Quote: hcf (quoted from post at 09:28:52 08/30/23) 1973 2030, diesel, built in Mannheim. Looking at replacing the water pump (failed shaft, coolant spurting from pulley, and I do not have access to a press or someone who does). All of the pumps I've found on line (Yesterdays Tractors, All States Ag, etc.) have multiple ports coming off the bottom of the pump (which the original does not and I'm assuming these are for cab heat). These are not removable as far as I can tell. Thoughts on how to plug or bypass these ports or any other ideas or a source for the correct pump without extra ports. Original pump is stamped R55758. Thanks.
AR55094 should be the part number for the pump having the housing with only the bypass port, there are a few out there, but most are subbing to the newer pump. YT/All States lists having the AR55094 as rebuilt. The newer pumps have two ports on the underside (in addition to the bypass port on top), primarily for cooler lines for the engines with oil coolers, which came about after your 2030 was built. The new pump will fit your engine. If you get one of those newer pumps look for one that comes with the threaded plugs and port nipples (some are pressed in) so you can set it up as needed for your engine.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
