You can fill the pits with JB Weld, then sand the rod down smooth again, it's been done successfully here. The ram itself is not the most critical surface - it's the cylinder that it sits in that needs to be in good shape (and the pump cylinder). Before ordering that rebuild kit, you might want to tear it down and inspect the internals.
That doesn't sound right - there's probably more variation between orings than in the thickness of the chrome layer.
Hi. I was wondering if you could send me pictures of the tool you made and how much you'd want for it. I desperately need to buy one. I've tried to make one from cutting up some sockets, but like someone else in the post said, that didn't work for them either. I don't have access to welding equipment, so my resources are limited. but I'm finding this is my 4th case of needing this tool. the last 3, i cut it off and replaced the nut with the new style 47mm. but I'm also finding replacement nuts aren't easy to find. So i think its a good idea i hunt down a tool. thanks. Alan
Post 31 in this thread shows the tool I made. If it works for you then send me a deposit and I'll send you the socket. For more contact with me about this please use the private message system here and we'll work out the details. To PM me click my user name to the left and start conversation
