That's the lock tool for all OM60x injection pumps, and most - but not all - 617.95x pumps. For a while, a year or three ago, MB dealers in the USA were claiming they couldn't get that tool - no idea why. It's still on the MB price list and should be available but I don't know if anyone has tried lately. The OE part number is 601-589-05-21-00, and the price should be about $25 from Rusty. Here's a photo of the genuine item:

And, the eBay price sucks, when you can get the genuine MB tool for less from Rusty!! BTW - if anyone has bought one of these from a dealership in the past year or so, please let us know that they are now available once again. ;-) -Dave M. > ------------------------------ > Date: Mon, 16 Jan 2006 18:52:24 -0600 > From: "Kaleb C.
