UL Crank help.
I am having issues getting my crank set up and its keeping me awake at night. I had a set of OEM flywheels and I mocked them up and even with the crank pin nuts semi tight I could not spin the rods, after consulting a very knowledgeable friend he determined that the tapers were most likely worn out. I ordered a new set of T&O wheels and mocked them up to make sure my cases were good to go. I sent the wheels out and had everything balanced and last night I decided to build the wheels in hopes of truing them. Once again when everything is installed I cannot turn the rods with the nuts lightly tightened. I believe that the culprit is the thrust washers, I am using the standard size washers (Vtwin p/n 10-1284, OEM 23972-36) so i dont know why this would be happening. There are no options for thinner washers, only thicker. Im using the correct crank pin for the T&O wheels, I dont have the p/n on me at the moment. Please help! Thank you all in advance.

I would wonder about the pin. Is it stepped or not? Do you have a manual to verify the rod width is in spec? I had a lot of challenges with my 41 UH crank pin (bought 3 or 4 in the end) and getting the combination right.

I got this figured out. After taking a look at everything, T&O flywheels come with the thrust washers already installed and I was doubling them up. Now I can true the wheels. Just one of those things i didnt think about. Thanks!

Looking at the pinion shaft the rear connecting rod is the rear one
install the key way pin in the wheels and torque to spec - a machinist trick for tapers is to use talcum power on the NON keyed pin taper its easier to slide at 80 to 90 pounds when you set it for truing
