Tool, Rear Hub & Engine Flywheel, Torque Master
If you have ever removed the rear brake drums, or the flywheel off your engine, you'll be aware of the incredible amount of torque required to tighten the 36mm nut back up again. This fantastic tool makes the job easy though, as it multiples up the leverage, which means you can use a normal sized ratchet and torque wrench.
Can be used on 4x130 and 5x205 rear drums with a 36mm castle nut, and also 6v and 12v flywheels. A well designed product, that makes the above jobs a joy.
