• Specialty tools
The main tool that you need that you may not already
have is the Posi Lock TJ1 puller. This is a large puller that
will attach to the sides of the pulley to disassemble the cvtpushbelt.com Tool Kit
transmission and pulleys. This puller will work on most
CVT transmissions. Most transmission parts stores now
carry this puller. You can also find them online.
There are also other options of pullers from Transgo and
Adapt A Case. CVTpushbelt.com offers a complete tool
kit for this transmission.
Some large sockets you will need are 32mm, 46mm,
50mm and 55mm.

Belt Handling
Special thanks to Coen van Beek
Never take out the two pulleys together with the belt out of the transmission.
The chance of damage on the belt is about 95% (See next slide).
Follow the instructions described in the User Guide Toolkit for RE0F09A/10A.
Contact area is perfect!
We see this way of disassembly very often in
workshops.
This damage will result in a
warranty case and will cost you a new belt + labor.
The belt will brake within 10-5000 miles.
Handle the belt with care. Store it
These Pushbelts are designed to
during the job in a clean plastic bag

save you a lot of trouble and money.
