Clutch jam problem

[dorji12345]

Sir...
I recently around 1month ago...I changed my clutch and pressure plate of my i20 2011model...
Right after than it started giving me problem...
When engine is cold or cool... Engine runs smooth but when slowly engine gets heat up the clutch automatically gets jam and come in normal position after cooling down of engine.
Today also did total maintenance...open clutch chamber and look but couldn't find any prob.
But still the clutch jam problem exist...why is this happen???

Some part(s) getting hot and expanding. Then stick/jam.

Check all your tolerances and torques.
