There’s a bearing right behind the front housing of the compressor that needs to be cleaned and greased. We couldn’t rent a clutch puller for free, so being cheap bastards, we improvised. The clutch plate has three 5/8-inch coarse-thread bolt holes, so we used a harmonic balancer tool and pulled the clutch back about 5/8 inch from its shaft, which relaxed everything enough to gain access to the bearing. It was butch, but it worked. When we were done, we just tapped the clutch back into place.
