Replacing a belt on turbo trainer

[Soltydog]

Any advice or tips most welcome, if anyone has experience of doing this?

The turbo trainer in question is an Elite Roteo/Volano.
Whilst using it last night, it appears that the belt may have slipped of a couple of ridges & then split
I've found a replacement belt for about £20, but looking at it, not sure how easy it will be to replace & get tension right, not even sure if it's something LBS would do

After contacting Elite in Italy, they sent me a new belt FOC & told me to refer to my instruction manual for fitting advice. Great, except I couldn't find the manual
Anyway took all the covers out & sussed out how to fit & tension the new belt. I wasn't sure how much tension to apply, but had a steady 45 min session & all feels ok, so fingers crossed, the jobs a good one. I'll be keeping my eye on the belt over the next week or so & check for any issues
