Description: Naraku Variator Lock Bracket Tool. This simple yet effective tool for 139QMB 4-Stroke makes installation and removal of the variator super easy. Naraku Variator Lock Bracket Tool does it by locking into place the variator‘s teeth. Thus, stop the variator from spinning freely. Once the variator is lock from spinning freely, you can easily remove the variator nut to remove the entire variator components drive face, boss, roller weight, etc. When finish tuning or upgrading variator components just securely re-tight with a torque wrench and remove Naraku Variator Lock Bracket by its two screws and you and your variator will be spinning freely again!

NOTE: Recommend using a new belt with any new CVT kit. Belt and the belt drive facing plates KEEP DRY. All, other areas apply moly-graphite grease when assembling.

Installation: Make sure variator drive face is seated properly and not get its teeth chewed by the Bendix: 1. Slack the belt by opening the CVT clutch gives belt slack to the variator side. 2. Then install the variator drive face while lifting the slack belt further away from the center boss if done properly should not see any splines between variator drive face slop-side and boss flat-side. Should be flushed together. 3. Then install the existing variator fan, washer, and hand-tight nut. 4. Finally, apply blue Loctitetorque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.
