About this 3D model

Adjustable cam pulleys for Volvo Redblock B21/B23/B200/B230/B234. 240/740/940 All three variants ready to CNC manufacture in aluminium. I recommend tapping for M6 Helicoil/ thread insert. I didn't use the special washers in the cad models, just plain washers. Also the text is removed as it was incorrect and markings are closer together. I run the square tooth 8v cam pulley on my 240 and it works well. The round profiles are not yet tested, but they fit niceley on a timing belt.
