Freightrain Posted June 27, 2006 Share Posted June 27, 2006 I'm in search of a new/used/better tranny gear for my speedo. I need the internal part(shaft with 13 tooth gear). I'm not sure how common this is? My speedo reads like 8 mph slow, so would putting a 11 tooth gear in tranny be enough to speed it up? Is this a common part?BTW, my gear is chipped and non-functioning right now.Anyone got pieces from there triplex laying around? Or is this still an available part Barry?

B42Art Posted June 28, 2006 Share Posted June 28, 2006 Freightrain, I have a Duplex TRD722 in my B42 and I had a bad speedo cable and tranny gear. I went to Mack with the tranny number and they had the cable and the tranny gear in stock. The gear retailed for $31.00. Give them a try. Hope this helps, Art Quote Link to comment Share on other sites More sharing options...
