There's a hole in the pump pulley that will line up with a hole in the mounting bracket when it's in the correct position to match the cam and crank. There's a special pin you can buy to place in there or a certain Craftsman deep socket is supposed to fit nice and tight as well. Following is some snippets on the subject from my archives. Thanks to those who contributed! The 7/16, 1/4" drive Craftsman socket does indeed fit, however, I've found that using a 1/4" drive older style Craftsman 11mm deep results in an even tighter fit. There's less than .005" slop. 25 years ago, I took that socket out of circulation, and keep it for setting injector pumps. I don't have a loose pump sprocket hanging around, but if you want, I could at least mic the socket. Advise if you want me to do so. My Mastercraft 13mm deep socket works great - it's a tiny bit loose, so I wrapped one layer of electrical tape around it, then jam it in, and it holds fine. I used a ¼" drive x 7/16 deep socket 12 point Craftsman HTH, Lee Oo-v-oO PP-ASEL KB1GNI ----- Original Message ----- From: "Will Taygan" <william at taygan.com> To: <vwdiesel at vwfans.com> Sent: Sunday, March 28, 2004 9:15 AM Subject: [Vwdiesel] 180 off on pump?
