sealed at this point it is best to check that the pump does not bind before sealing the head. 

12) Remove the open head by jacking it off the dowel pins, and install the open head slide pin and piston; again mak-

ing sure that the slide pin and piston are correctly positioned as described for the center piston. 

13) The open head could now be sealed, but it is best to check that the pump does not bind before sealing the head.  

Install the open head with dowel pins and four screws. 

14) Turn the pump to ensure that there is no binding.  If binding does occur it is necessary to dismantle the pump and 

correct the cause. 

15) Remove the closed head and make sure the sealing surfaces on the head and cylinder are clean.  Apply a thin coat 

of Kinseal to these surfaces.  Allow the surfaces to become tacky before joining them. 

16) CAUTION: If too thick an application of sealing compound is used, it will squeeze into the pump during assembly 

and cause parts to stick or even clog the oil piping. 

17) Install the closed head on the cylinder, tap the dowel pins home and tighten the screws securing the head.  Rotate 

the head to ensure there is no binding. 

18) Repeat this process for the open head. 
19) Install the oil pump housing and O-ring to he closed head.  Install oil pump and O-ring to housing.  Apply vacuum 

oil or grease to O-rings before installing. 

20) Install the shaft seal as follows: 

a) Remove sharp edges and burrs from the shaft seal to prevent damage to the shaft seal. 
b) Lubricate the shaft and seal head assembly with vacuum grease. 
c) Replace the seal backup ring and slide the rotating portion of the seal against the ring with the carbon face 

outwards.  Be extremely careful not to damage or cut the rubber. 

d) Coat the seal seat with vacuum grease and press it by hand into the shaft seal bearing housing.  Assemble 

the bearing housing and seat to the open head. 

e) Insert the bearing backup ring against the shaft shoulder and tap the outer race of the bearing into its hous-

ing.  Tighten the bearing locknut and rotate the shaft to check for binding. 

f) Reconnect all external lines except to the separator housing. 

21) Install the discharge valve(s). 

a) Place the compound plate with its top and bottom gaskets in position, and install the interstage relief valve.  

Install the valve deck cover and fasten it in place.  Install the discharge baffle assembly.  (On the KTC-60 the 
umbrella is fastened to the separator housing.) 

b) Lower the separator housing into place and tighten the retaining screws inside, then the outside screws.  Go 

back and re-tighten the inside screws.  

22) Connect the oil line to the separator housing. 
23) Reconnect the wiring. 
24) Install the sheaves and belts.  The V-belts should be adjusted as described in the MAINTENANCE section. 
25) Install the belt guard. 
27) Fill the pump with oil as described in the OPERATION section. 
 

REPLACEMENT PARTS 
 

Various parts, particularly internal components for earlier versions of KTC series pumps are different and cannot be in-
terchanged.  Many pumps are ordered and equipped with special modifications and accessories, or adaptations for 
special fluids.  Therefore, when ordering spare parts the pump model and nameplate serial number must always be 
provided to ensure verification and shipment of the correct parts. 
 

RECOMMENDED OIL 

 

KINNEY AX Oil is recommended for the KTC pumps and it is available from the factory and Distributors under the follow-
ing item numbers:
