5.If it was necessary to remove the priming piston rod (24) from the piston (23), apply thread sealant to threads of the rod. Place flats of piston in a vise. Hold flats of rod with an adjustable wrench, and screw rod into piston; see the following table for cor- rect torque. Be careful not to create burrs on flats of rod.

Displacement
Pump	Torque
60cc and 100cc	34-38 ft-lbs (46-51 N•m)
200cc and 250cc	92-102 ft-lbs (124-138 N•m)
500cc	90-100 ft-lbs (122-135 N•m)

6.Place flats of displacement rod (1) in a vise. Install piston seat/guide assembly onto the piston (23). Apply thread sealant to threads of rod and screw piston assembly onto rod; see the following table for correct torque.

Displacement
Pump	Torque
60cc and 100cc	85-95 ft-lbs (115-128 N•m)
200cc and 250cc	239-271 ft-lbs (323-366 N•m)
500cc	327-363 ft-lbs (441-490 N•m)
