Either is your device for pushing the old pin out (punch, pliers, etc.) or the way you push the new one in, or the things you do in between.</div><div>The first one: you have to be very careful when you push the pin out. The first thing is to note if the old pin has rough edges (one or both of them) due to technicians that cut both sides of the pin after inserting it or, worse than this, technicians who file the end of the pins so you don't see the rough cut but a smooth surface. If there is only one side cut then you have to push the pin out by the clean side being careful to put your tool right in the middle and realy straight so you don't scratch the bushing. It's very important not to go all the way through with the tool because you will push the bushing inwards tightening it the same way that the tool for tightening key bushings works. This depends on the tool you use… If the pin has cuts on both sides or it has been filed then whatever you do will damage the bushing…  So, pushing the old pin out can make damage to the bushing that will result in tightening temporarly the bushing. Notice that I said temporarly. if you put the same size of pin after a few weeks it will be loose as it was the other one, or even worse if you loosed the bushing  with a reamer or file for fitting the new one… If you are repinning there is no way you will put same size pins, it have to be at least one size up.</div><div>I won't talk right now about sizing up the new pin, but once you got it right then you have to be very careful tu put it straight and push it with a straight surface so you don't tight it when you press at the end (there are some tools that have an indentation for the pin and can work as the key bushing tightener tool).</div><div>So my assessment is that there is no wore in the pins but some kind of swallow of the bushing while in the process of repinning.</div><div>To test if something like this is happening just take one of your tight repinned piece and apply one drop on each side pf protek center pin lubricant and wait a few minutes and balance it a few times and you will notice that it is loose. If this happens you need to put in a thicker pin.</div><div><br></div><div>Rafael</div><div><div apple-content-edited="true"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Optima; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Optima; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>_________________________</div><div><br></div><div>Rafael M.
