DARKHORSE MOTOR COMPANY Universal TIR Tool Kit — Pinion shaft, Sprocket shaft, Black

🔧 This universal tool kit measures total indicated runout (TIR) quickly and accurately on compatible models.

• Install the supplied indicator in the laser-marked hole, attach it with the supplied thumbscrew to the mount surface or inner primary, then rotate the tool arm to touch off on the shaft for a precise measurement.
• The tool measures total indicated runout of either the pinion or sprocket shaft and can determine the actual runout the compensators operate with on '07 & later models.
• Includes five small cylindrical magnets that fit into the grooves of the fine splines to check whether splines are cut off-center.
• Made in the USA.
