F123 Series PM Kit Includes:

- 1 x Z drive belt 

- 8’ x 3/16” material feed tubing 

- 1 x Y block (OEM Kit includes 2 Y blocks the 2nd for Support but why since Support only runs on average 1/3rd the time of Model. Therefore Support Y block only needs to be replaced every 3 Years. If you want to replace both Y Blocks call for price of an extra Y block added to the Kit).
