Darkhorse Universal Crankshaft Runout Tool for Harley Davidson V-Twin Engines
As the industry leader in performance lower ends, Darkhorse Motor Company know importance of accurate measurements of crankshafts in their installed state in crankcases. It is the primary reason this simple yet Universal TIR Toolkit was developed over and above the original run-out tools on the market for sprocket shafts only.
Darkhorse plotted out all the different configurations to manufacture a tool that every technician could have in his own personal toolbox. From 1970’s Shovels, through the Evolution and Twin Cam platforms, to Late Model M8’s, this Universal TIR Tool cover’s every Big Twin dating back over 50 years.
The tool measures Total Indicated Runout of either the pinion shaft or sprocket shaft with the unique capability to accurately determine what the actual run-out the compensators operate with on 07’& later models. There are 5 small cylindrical magnets that attach into the grooves of the fine-splines and allow the indicator to also measure if the splines are cut off-center. This critical measurement will also tell a lot about premature compensator wear or noise in the primary system.
Install the supplied indicator in the corresponding laser marked hole and attach to either the cam plate mount surface or inner primary using the supplied thumbscrew and rotate tool arm to “touch off” on the corresponding shaft and you are measuring TIR, quickly and accurately! No need for multiple single purpose tools.
Works with:
Shovelhead, EVO, Twin Cam, & Milwaukee-8 engines
