I got my crank after being nitrited. It’s beautiful. The rotating assembly was balanced and I was wondering if I should have a roll pin or just line up the holes when attaching the flywheel.
Dean, the addition of the roll pin will not alter my balance work. It is VERY close to the center of the mass and will have no impact on balance. The nitriding process requires that this pin be removed and they probably forgot to reinstall it. If you want to install one you can buy one at the local hardware store.
Do not hesitate to email us for direct support with questions like this, its what we are here for.
I only offer the cranks already nitrided, I do not offer the service for customers that have their own crank. The Nitrided cranks are listed on my site.
