I am going to ask him about the bushing and oiling it or not. When I dropped it off last Thursday he checked it out for me first. He said it was weak. Maybe he is not used to Lucas starters. It is still going to look weak after he re-builds it. It is definitely not a gear reduction kind of speed.</div><div id="yui_3_16_0_ym19_1_1482172302549_63601" dir="ltr">Mike MacLean<br></div><div id="yui_3_16_0_ym19_1_1482172302549_63329"><span></span></div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: times new roman, new york, times, serif; font-size: 16px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font size="2" face="Arial"> On Monday, December 19, 2016 8:43 AM, Bob Spidell <bspidell@comcast.net> wrote:<br></font></div> <blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; margin-top: 5px; padding-left: 5px;"> <br><br> <div class="y_msg_container">re: "If I am not mistaken there is a small hole in the back plate of the <br clear="none">dynamo (and starter?) to lubricate the bronze bush now and again."<br clear="none"><br clear="none">You are not mistaken.
