should remain free of oil and grease. Tension should be removed from belts if the drive is to be inactive for an ex-
tended period of time.
DISASSEMBLY
The following steps are for complete disassembly of the pump, however the pump should be disassembled only to
the extent necessary for servicing. Refer to the illustrations and parts list as needed. Note that the open head is the
head through which the shaft extends, and the closed head is the head on which the oil pump is mounted.
1) Disconnect the pump from the power supply.
2) Drain the oil as described in “Changing the Oil”.
3) Remove the belt guard.
4) Disconnect all leads from solenoid valves, pressure switch and motor junction box.
5) Loosen the jam nuts and release the belt tension and remove the V-belts.
6) Remove the pump sheave and key, spacer and locknut.
7) Remove the oil piping to the shaft seal housing.
8) Remove all the screws securing the shaft seal/bearing housing and use two screws to jack the housing and bear-
ing off the shaft. Remove the O-ring.
9) Pull the seal head assembly (the rotating part of the shaft seal) off of the shaft, this may require a heavy pull if the
unit has heat bonded to the shaft. In extreme cases it may be necessary to break the bond by removing the open
head from the cylinder. Remove the shaft seal backup ring. If necessary press the seal seat (the stationary part
of the shaft seal) from the bearing housing.
10) Disconnect the oil piping between the separator housing and the oil pump, the closed head and the heat ex-
changer. Remove the piping between the cylinder and the closed head.
11) Remove the separator housing cover. On the KTC-112 remove the valve deck cover complete with umbrella.
On the KTC-60 remove the umbrella from the top of the separator housing, the nipple from the valve deck cover
and then the valve deck cover itself. Remove the relief valve(s) then drain the discharge valve chamber (if not
already done), and remove the discharge valve retainers and discharge valves.
12) Remove all the screws from the open head and using three or four screws in threaded holes in the head to
break the seal jack the head off of the cylinder. Remove the open head.
13) Pull the open head slide pin and piston from the cylinder. Mark the parts to insure that they can be replaced in
the same location.
14) Pull the open head cam off the shaft.
15) Replace the open head and dowel pins using four screws to hold the head. This will support the shaft while the
closed end of the pump is dismantled.
