Does anyone have the correct Part No's for a TT after fitting an under drive pulley. Dayco belt numbers would be fine. I was sure there was a link on the forum detailing the correct sizes.
There was a link a while ago. If you don't get a response I can look on my motor for you tomorrow. Found it under the following search in the tech section Crankshaft Underdrive Pulley installation Underdrive Pulley Install Before you start you will need the following items: Metric socket set ranging from 8mm to 27mm 3 leg pulley...

You're in luck that as I started putting on my belts the other day I thought a snap of each may come in handy to someone else.... The only thing I can't tell you is which one is which as I didn't get that far. They're for a set of four Unorthodox pulleys if that makes any difference.
Yes it does. My underdrive pulley is smaller in diameter than the GFB version. Also if you replaced the other pulleys.
Quick way to measure a poly-groove belt run is to use some 3mm wire. Thinner, like string will give an incorrect length by a few mm. usually not too much an issue....but, can be annoying if a bely is chosen that is 5mm shorter and thats the 5mm you needed to actually flick it on!!!! Hold one end of the wire down with a finger in a convenient spot and wrap the rest of the wire around the other pulleys on the same groove. Pull tight and where the ends overlap, just mark the long free end of the wire with your fingernail. Measure off between the end of the wire and the mark you made with your fingernail and there you go. So a 4 groove run at say 880mm will be a 4pk880 belt. Voilah! No need to ask for belt lengths ever again!!! E
You can probably guess what I did when two of the belts I got were right and one was wrong. Yep measured it and as you say Viola all is good.
