I am needing to replace the drive coupling for the Simms pump. The pump drive flange is no longer available from CNH and only available aftermarket. I recently purchased the entire part assembly via Ebay and found that the keyways are cut too small. A further web search seems to suggest that this particular part is made by only one facility, but sold by many vendors [they seem to all use the same photo of the part]. Have any of you successfully replaced these parts and where did you obtain them? Or, have any of you encountered the same problem, and how did you solve it? Please note that I am not referring to the fiber disc, which is still available from CNH, but to the steel flanges on both the pump and drive shaft. I have the capabality to recut the keyways, but would prefer not to go that route. I can return the parts, but that leaves me nowhere at this point. Thanks for any ideas!
