Bill13205 Posted January 15, 2012 Share Posted January 15, 2012 Hi, I'm coming to the conclusion that 74, 75, & 76 Yamaha DT fuel tanks (175 in particular) are NOT interchangeable. Lets find out shall we. If you would indulge me, please measure your 74, 75 or 76 DT fuel tank from the centerline of the forward mounting ears to the centerline of the rear mounting hole. Mine measures 17.75 inches. Mine is could be a 75, I'm not positive. What does yours measure?? Thanks Bill Link to comment Share on other sites More sharing options...

Bill13205 Posted January 15, 2012 Author Share Posted January 15, 2012 AH, The part numbers (from the Yamaha fractory site) for the 75 DT 175B tank (they had two paint schemes that year) is 443-24110-10-01 for the older design and 443-24110-00-01 for the style that I have. The 76 DT175C tank part number is 558-24110-00-02. 443-XXX is the designation for the 75 model and the 558-XXX is the designation for the 76 model. I think that 24110 is the tank number, the next two -the cap and the final two the color, I could be wrong, but that's what it looks like. There is nothing I can find of a part number anywhere on my tank, but it has the 75 older style gas cap. The TY is 1.2 gallons. Mine is at least 2. I looked at the MX, TY & YZ. DT is the only one that has the lockable tank. Do you have atank that you could measure. Thanks Bill Link to comment Share on other sites More sharing options...
Bill13205 Posted March 11, 2012 Author Share Posted March 11, 2012 Well I finally got the straight answer. It appears that for 74 and half of 75, the DT 100, 125 & 175 had pop-top fuel caps. The DT100 and DT175 tanks matched, measuring 16.5" The DT125 tank measures 17.75" Why you ask? No feaking clue. Half way thru 75, the tank paint scheme changed to the diaganal stripe. The cap was removable (but still lockable) As before 100 & 175 shared tanks and the 125 stood alone. In 76 all tanks changes to a "coffin style" tank. As before the 100 & 75 shared tanks (measuring 16.5") and the 125 was again on its own measuring 17.75". Now we all know Link to comment Share on other sites More sharing options...
