Okay. I'm totally full of cheap belts. In last month I have tried 3 different cheap belts. In all belts there was same size 918 - 22,5 - 30.
Belt brand was QINJIANG. (If you see one. Burn it!)
- First belt was 15mm too long and slipping at the very beginning. Sent it back and got new one by warranty.
- Second belt was same size than my 8000km driven Gates Powerlink. Unbelievable but this one lasted nearly 100 miles and then started slipping.
- Then I got that new warranty belt. Tried it and 20 miles later it was slipping.
- I started to questionize my self that if the problem is in the clutch. I had brand new clutch in box and decided to try it with new belt. Contra spring in new clutch was noticeable stiffer. I tought it might hold belt harder. But noooooo. In my dreams. Same slipping.
Pfff... Put back on my good old worn Gates Powerlink and no slipping.
And grease cannot be the reason for slipping. I always clean clutch plates and variator plates and v-belt with break cleaner spray. Everytime when I have to touch them.
Finally I took a video how these two different belts act when idle speed.
First cheap brand belt QINJIANG which driven only 50-100km.
Come on! Look how much it vibrates. And frequently it vibrates more and keep that rattling noise. No wonder it is slipping when driving if it vibrates that much when idle speed.
Then my good old 8000km driven Gates Powerlink. Same size.
Not much vibration and no rattling sound. Smooth action. No slipping when driving.
I hope no one want to buy cheap belt ever again.
btw. That cheap belt stretched 7mm after 50-100km.
