This appears to be a displacement pump model rather than a repair kit. The manual indicates use only genuine GRACO replacement parts and that use of non-GRACO replacement parts may void warranty. Part number appears in torque specification table for intake valve installation on cylinder. Uses wrench torque of 67 +/- 5 ft-lb (90.8 +/-6.8 N•m) Part 277069 is listed in the same torque group as models 248204, 253056, and 255968, all requiring 27 +/- 3 ft-lb (36.6 +/-4.1 N•m) torque specification for piston valve installation. This appears to be related to piston rod assembly procedures.
