@rlee63a4 posted:FWIW, I installed the PIM McLeod clutch, pressure plate and throw out bearing system in 2017. It was MUCH stiffer than the old, slipping, non-Pantera clutch I replaced, but the stiffness of the new clutch was never intermittent. So, I installed an Effort Reduction Kit a few months later, and the difference was noticeable. It was either that, or I was going to have to go to the gym to build up the strength of my left leg.
I had a similar experience when I installed a McLeod clutch, pressure plate, and throwout bearing on a 72 Pre L. Substantial effort was needed to press the clutch pedal. My solution was to add the clutch effort reduction kit, the one with needle bearings. The clutch was easy to operate after that change.
