2234 Primary drive lock tool

Locking the primary drive is essential when you need to loosen or re-torque sprocket and clutch nuts, and this JIMS primary drive lock tool is the professional way to do it. It fits securely between the primary chain and the front motor sprocket to prevent any movement during high-torque operations. Manufactured from POM, also known as Delrin, this tool is incredibly tough and strong, yet it won't mar or damage your teeth or chain like a makeshift metal wedge might. It fits a wide range of Harley-Davidson motorcycles, including 1936 to 2006 4 and 5-speed Big Twins, 1957 to 2020 XL Sportsters, and 1987 to 2010 Buell models. It serves as a high-quality alternative to OEM part number 41214.
