Glazed or worn friction material is what turns a healthy clutch pack into a slipping one, and it shows up first under load.ALLISON 1000 clutch pack lt1000 lt2000. Each disc...

When the clutch pack in an Allison 1000 series unit wears down, no amount of adjustment recovers the engagement feel or stops the slip, and this friction pack is the...
