Change bearing in tension pulley?

[jackmanjls]

On a yamaha F90TLR is it possible to change the bearing on the tension pulley?

It's the pulley (cost ~$150) that keeps tension on the drive belt.

Would someone know the bearing ID to use?

Yamaha doesn't offer a replacement bearing.

Does that mean it can't be replaced? Seems to me that one could match size and save a bundle of $$$.

dunno
as I am a master technician and work at a Yamaha dealership I have never tried a jury rig on them.
However a sealed bearing is a sealed bearing.
