Clutch linkage or Clutch Spring

Clutch box would refer to the main clutch pedal linkage assy mounted under the floor of the truck.

Pete? Which model?

This could be the issue? You really need to disconnect the adjustable link to isolate the issue and find where the binding is.

 

You do not need to remove the trans to replace the clutch box. It is a big job though as it is monobolted/riveted to the cab floor. Not a job for the DIY guy. Both pedal pivots for leverage are contained in an aluminum box, hence the name.

 

If its same as 379 petes their is a grease fitting on the side of it. Hard to get at. I used to reach up over the air tank ( one thats mounted below the drivers door) and feel around for it and get grease nozzle onto grease zerk. If a person don't know its there, probably never been greased. Getting trk greased at certain shops, bet they don't touch it.

 

^^^^ This is true. Most newer chassis -389- that still use the box often come with remote grease lines which make the lubing much easier. Pretty sure its an option.

I had a 389 in a few weeks ago with the same complaint as the OP. Inside the clutch box there is a steel link with ball studs that are not servicable other than spraying externally. One of these ball stud pivots was frozen up.

2019 truck with around 60k on the clock and regular services.

Replacing the link corrected the issue.

 

Right. My 1993 didn't have the remote. My 01 does ,makes it nice. My friend has a 2014 389 he said awhile back his clutch pedal wasn't returning. First pete he has owned. Told him about it.
