When the black BB reaches the 
1cc/min mark on the black ball 
scale, compare the fluid currently 
supplied to the fluid floor and target 
amounts. 

 

If the supplied amount is above 
the floor, the feed end may be 
pinned. 

 

1/0 and smaller cables may be 
pinned even if the supplied fluid 
is lower than the floor. 

 

The limited space in these cables 
might not allow enough fluid to 
reach the floor. Pin the cable. 

 

Figure 16:

 Liquid flow meter BBs are at 1cc/min.

Pin the inlet. 

 

Close the ball valve to the injection tool to prevent fluid spray. 

 

Insert the plug pin into the IA with the injection tool. 

 

Remove the injection tool from the IA. 

 

Check the plug pin hole for leaks and tap the pin in if it is not flush.

 Non-flush plug pin. 

 

Wrap the saddle chain around a rag to protect and keep debris out of the injection tool.
