Needed to call the company to find out the equivalent and they directed me towards MRO. If this one will last as long as its predecessor I'll be retired by the time it will need to be replaced again. - Right on - Took a bit to ship but after it shipped I got it fast. Right product. - Grove gear - ordered it got a week early was exact to the specs performed flawlessly
