Our billet-steel flywheel is a new 27-lb unit that bolts directly to the 1UZ, 2UZ, and 3UZ crank snout – without modification or spacers (like a good flywheel should).
The flywheel is five pounds heavier than a stock cast-iron flywheel, expands low-RPM torque, and improves your ability to maintain engine speed while driving and crawling.
NWT’s flywheels are designed, machined, and built in the USA.
Installation Instructions: Always ensure that the negative battery terminal is disconnected before working on your vehicle. Remove the old flex plate from the crank. There should be (8) 14mm bolts that need to be removed. Once removed, the flex plate bolts can be disposed of. With the flex plate removed, a spacer is located behind it. The spacer can also be removed and disposed of.
At this time, check to see if the rear main seal is leaking oil. If so, replace the rear main seal with a new one.
The new flywheel is coated in pickling oil and can be slippery, so be careful not to drop it. Place the flywheel on the end of the crank. The flywheel is designed to be a tight fit over the crankshaft, so it most likely won’t be able to be pressed on by hand. With the flywheel sitting on the end of the crank, install (2) 3VZ flywheel bolts and use them to press the flywheel onto the crank. With the flywheel pressed against the crank, you can back the two bolts out.
Check the UZ starter for proper engagement on the ring gear. The starter gear should engage the ring gear about ½ way into the ring gear.
With the flywheel now installed, it’s time to install the Loctite onto the threads of the flywheel bolts.
