We sent an email to customers today stating these things:
- A limited number of teams have reported cracks and breaks in the Rev 3 pulleys, approximately 3.7% of the total number of Rev 3 pulleys sold.
- We conducted rigorous tests and were unable to consistently replicate the failures with the Rev 3 pulleys that have been reported to us.
- Thousands of the Rev 3 pulleys are out there, many currently in use, with no signs of failure.
- We stand behind our product and will replace any pulley that has evidence of cracks or breaks. Obviously, a pulley failure at a crucial time could be devastating. So, even if your pulleys have not failed, we will provide any Rhino Track Drive customer, upon request, up to 2 pulley sets per track drive (4 per robot).
- For ease of reporting the failures we have developed a form for customers to report any pulley issues and request replacements.You can access the form here: www.andymark.com/RhinoPulley
