Exmark lazer z s 48” drive idler pulley torque?

[Jtch75]

looking for torque specs for the drive idler pulley on my Exmark laser Z S 48”

The torque for the 3 nuts on the idler arm would be appreciated

Also do the drive pulleys get hot. Mine get a little hot. No burning smell or smoke.

This should have a washer the size of the metal bushing in the center so it does not contact the plastic part.
These only last so long b/c there is no way to lubricate them to my knowledge. If it turns freely that's about all you can hope for. I've never torqued one , they usually come with a lock nut on the underside to keep the nut from backing off so once it's good and tight , this is where I leave it.
You can get torque specs for the size of the bolt ( 5/8 " 1/2 " ) etc. Just off the top of my head I'd say 50 - 75 lbs
