May 28, 201412 yr I am in the middle of assembling crankcase halves for my TY 175. Because the guy who owned it before me only used one dowel when he re-assembled the crankcase last time, I did not realize (until just now) that a needed two of the things for the upper and lower mounting points. I noticed when I was trial fitting the dowel to the lower mount that it fit snugly and would seem to do a good job of reducing vibration. However on the upper mount, it was so loose as to be apparently useless. Are there two sizes of dowels? Are there two sizes of O-Rings?? For pictures or to follow the restoration of this bike, take a look at my blog at http://meditarivemachinery.blogspot.com/ Thanks....any thoughts on the dowels would be appreciated. I really want to get this right. Mike
May 30, 201412 yr Author Problem solved. A guy on eBay had two NOS dowels and seals. They are on their way to me as we speak. In the meantime, I will probably get to work painting my seat/tank unit... meditativemachinery Mike
June 1, 201412 yr Author I really do not want to grind this up too fine, but I really have figured out the problem. I essentially misread the Haynes Manual. There really is only one dowel with the sealing rings around the circumference. That dowel is located inside of the rear, lower engine mount. And...I have one. Unfortunately, I just bought two more, so if anyone needs one or two of these little buggers, do not hesitate to send me a note. I can probably send it to you for little more than the cost of a new engine... Cheers Mike
