McCleod hydraulic throw out bearing adjust

They do have clearance. There is a spring inside the green boot. There is a stop built in to keep them from over extending. When replacing (and adapting to other applications), care must be used to ensure they are preloaded enough that a full stroke of the pedal does not over extend them and break the stop. Doesn't sound like you've ever replaced one

The problem is you're mixing your terminology. You're using the word "clearance" interchangeably with an air gap and with preload.

The OE style bearings do not require an air gap, therefore, they do not have clearance to the clutch fingers. The TO rides constantly on the clutch. They do need to have the amount of preload set appropriately, as described in the video I linked earlier.

I currently run an OE style hydraulic TO on the T56 in my Duster, so your assumptions about my experience are also incorrect. No need to make this personal, we're talking about the same thing.

You should ask Mcleod about Mcleod products or read the instructions on the site. There are bearings made for constant contact and ones made to have clearance. The linkage is another matter. You should be able to push the bearing away from the fingers.

See, now you're using "clearance" to mean an air gap again.

Most aftermarket hydraulic TO's have an air gap, like the McLeod that clementine has. He needs to set the clearance on that air gap.

Many OE hydraulic TO's have a spring, like the one in my T56. They need to have their PRELOAD set appropriately. Both styles often require shimming to set their depth properly.
