Spline to Spline i'm getting 1 1/4", and measuring just the round part of the shaft with no splines I'm at 1 1/16". $$T = F\ell = 200 \cdot 0.5 = 100\text{ kNm}$$. I'm designing a part to be used with this screw and I need to find the shaft diameter. // Calculate four digit year. Start measuring from wherever the screw head would rest on the surface when it is fully screwed in. The easiest and most accurate way to measure the shaft length on a clock movement is to use the depth gauge on a digital caliper. That allow would mess up and produce significant differences in the loads. length, journal size & U-joint series are critical dimensions requiring accurate measurement. The shaft height of each boot is listed in the product description. Please welcome Valued Associates: #958 - V2Blast & #959 - SpencerG, How to calculate the diameter of a transmission shaft from RPM & Torque. On the back side of the "seal head" (the end which fits towards the "spring"), measure the inside diameter. The smaller diameter shaft (at bottom) still has a small amount of room at the edge of the tip with the dime shape, but is right on the edge with the nickel shape. Measure at the end of the pipe. C is where the inner bearing sits. It is important to have the suspension in this position to measure correctly. To determine the spline size of a component (rack and pinion, steering column, and steering box), measure the outside diameter and count the number of splines.If there is a flat spot on the shaft and some of the splines are missing, count halfway around where there are splines and double that number. This is because a 60° arc (30° in each direction) on a nickel radius is just about 10mm wide and on a dime radius it's just a little less than 10mm wide. Measure OE slip yoke with a precision tool to determine which yoke you need. For woods, it will be either 0.335" or 0.350".
