jib lead block sheaves

[Coosaw]

In 2018 and again this month I have had to replace broken sheaves in both port and starboard jib lead blocks. The manufacturer of the blocks confirmed that I am using the proper size blocks for my working jib and also said that my problem was very unusual.Over the last three years I have day sailed my Cape Dory 26 approx. 30 times when the jib was used. Has anyone else had a similar problem and if so how did you solve it.

Make and model of the blocks would help and a photo could also be useful. I’ve never had a similar issue and I’ve never heard a similar complaint. Something is surely amiss. Any reputable brand would have replaced them and probably been interested in their return so a root cause analysis could be performed. They would not want their reputation besmirched due to failures in the field.

Jim,
Thank you for your response.
The blocks have been returned to the mfg. and I am waiting to see what action they take--hopefully a no charge replacement of the sheaves. I did not disclose the name of the manufacturer on purpose but they are well known and reputable.
