Attach the serviced dust cover assembly to the gamma-ray source projector with the socket head 
cap screw (SCR311).  Reattach the dust cover assembly to the gamma-ray source projector and 
ensure the cable will allow attachment to the lock mechanism and storage bracket above the lock 
mechanism. Replace the dust cover cable if it’s frayed or broken.  
 

8  Check the plunger lock for proper function by using the key to engage and unlock. Engage the 

dust cover assembly to the lock mechanism to ensure smooth operation and proper function. 

 

See reference drawings with part numbers in Figures 12 and 13. 

 

h.  Post Maintenance Functional Safety Check of the Entire System  

 

1  Operationally test for proper function of the entire system by using the serviced gamma-ray 

source projector, a source guide tube with a bayonet-fitting, the remote controls and the 
applicable mock source assembly (A424-14XL or A424-13XL). 
 

2  Attachment of the bayonet source guide tube to the outlet port must be smooth and without 

resistance.  Rotate the outlet port mechanism to enable exposure of the demo source assembly. 
 

3  Connect the (serviced) remote controls to the demo source assembly connector and the device 

locking mechanism.   
 

4  Push the lock slide into the EXPOSE position and crank the remote control cable into the 

exposure mode.   
 

5  While cranking the mock source assembly from the gamma-ray source projector, carefully feel for 

resistance or snags.   
 

6  During retraction of the mock source assembly back into the gamma-ray source projector, 

carefully feel for any resistance or snags during movement.   
 

7  Conclude the test by verifying the lock slide automatically secures the mock source assembly.  

Action of the lock slide should be smooth with an audible ‘snap’ during automatic securing.  After 
automatic securing, attempt to expose the demo source assembly from the gamma-ray source 
projector to confirm a positive capture.  Repeat this testing several times.   
 

8  If resistance, snags or sluggish movement of the lock slide is discovered during this testing, 

remove the outlet port and locking mechanism plates to determine the cause.  Repeat all safety 
function tests if any additional servicing is required. 
 

9  If the Model 550 jumper gauge was used during the servicing, clean the jumper gauge in solvent.  

Lubricate the inner sleeve with light oil while moving the sleeve back and forth.  Apply a light coat 
of oil over the entire jumper before storage.   
 

10  After performing the full servicing of the system, reload the gamma-ray source projector by 

performing a source transfer. After performing the source exchange from the source changer into 
the gamma-ray source projector, conduct radiation surveys of the gamma-ray source projector, 
source guide tube and source changer to confirm the sealed source is fully shielded and secured 
within the gamma-ray source projector. Survey the surface of the gamma-ray source projector to 
ensure the measureable dose/rate is less than 2 mSv/hr (200 mR/hr) on the surface and less 
than 50 µSv/hr (5 mR/hr) at 1 meter (to comply with ANSI/ISO requirements). 

 

11  If previously removed for the servicing of the gamma-ray source projector, install the source 

identification tag to the gamma-ray source projector.
