Reassembling Pump

Fit relief valve into housing bore using a protective plate, tap valve with a hammer until it abuts seat in housing. Fit vanes onto assembly pin, lubricate each bearing. Insert pump drive hub in a vise, then fit vanes into rotor, ensuring that one vane is positioned adjacent to stripper. Do not remove assembly pin at this time. Fit a carbon shoe to each side of every vane, ensuring that shoes are fitted with their bearing surface adjacent to vanes and with rounded point of contact toward outside diameter of rotor. Fit and adjust three shoe springs into each of deepest shoe slots, ensuring that curved portion of each spring is nearest shoe. Push springs flush or beneath rotor surface. Press rear rotor bearing into ring until bearing is 1/32" below surface of rings. Press lettered end of bearing only. Lubricate bearing. Fit carbon ring and a new carbon seal onto rotor end. Apply an applicable thread locking compound to socket-headed cap screws, secure rotor ring to rotor and torque to between 30 and 40 in. lbs. Now, remove assembly pin from vanes and start end cover into position. Move cover radially until pivot pin is located in vane bearing. Replace end cover retaining screws, and progressively torque screws to between 10 and 16 ft. lbs.
