Half way through my first Cambelt change, so far so good!, have an issue with how much play should the idler pulleys have. Pulley on vertical cylinder spins freely and shoes no lateral play, however the horizontal pulley shows a little play, less than a mm. Horizontal pulley spins freely. Is this amount of play acceptable or should a new bearing be bought?

Fingers crossed for the rest of the service.......

Any tips welcome, finishing it off tommorrow, getting too dark in the garage!

When in doubt, change it. There really shouldn't be any play at all, maybe a tiny, tiny bit.
