Lubricate the shutter

Pentax recommends using shutter oil to lubricate areas of the shutter that move rapidly during an exposure. Most of the critical areas can be accessed at this point in the disassembly. Apply the oil sparingly, just enough to coat the bearing surfaces.
Lubricate the pinion shafts. On the wind side, the pinions turn in their end pivots. The oil should be between the shafts and the end plates.
Lubricate the rollers. On the rewind side, the rollers turn on the fixed shafts. The oil should be between the rollers and the shafts.
Lubricate the high speed cam seat. The high speed cam spins rapidly in this hole during an exposure. It should be cleaned and lubricated.
