Dear Mr. Yuthana,
From Christy side, we are informed about your claim about noise on YSH-100 after replacing Load Sheave..
According to our record that we did deliver you #200196 Load Sheave * 20 pcs produced by new mold with maching improvement with order BB-59-001 by March 2016 as free replacement.
In order to make the problem clear, please confirm by return:
1. serial numbers of YSH-100 with noise after replacing load sheave?
2. do you replace our new load sheave to noise YSH-100 and noise trouble happened again?
3. how many trouble load sheaves had been replaced?
4. does the replaced trouble load sheave include our delivered new machined load sheave?
YSH-100 22-2015002378
YSH-100 222015002378 YSH-100有異音
Your assistance with reply to above is much helpful for us to solve the trouble.
