SETTING THE MICROMETER FOR THE PROPER CRIMP DIAMETER

The micrometer is mounted to a tie rod of the crimp machine. With the correct micrometer setting, the machine will produce the desired 
crimp diameter.

The crimp diameter specifications are listed in the PowerSource Crimp Spec Tool at danfoss.com/crimp for crimp spec details.

The exact micrometer settings may vary from one machine to another due to manufacturing tolerances. Furnished in the back of this 
manual is a sheet of approximate micrometer settings for the first crimp. A calculation and a micrometer adjustment should establish 
correct crimp diameter.

Example:    

Aeroquip 2681-12 hose requires a crimp diameter of 1.90-1.96. The recommended micrometer setting for set  

   

 

up is .739. The micrometer was set to .739 and a sample fitting crimped. The crimp diameter obtained was  

   

 

1.216. The nominal crimp diameter desired is 1.193. Subtracting 1.193 from 1.216, we conclude that our socket  

   

 

is crimped .023 oversize. Each .001 change in crimp diameter requires a .004 change in micrometer setting.  

   

 

Therefore, .023 x 4 = .092 change in micrometer setting. Add .092 to .739 to obtain a new setting of .831.

Crimp the same fitting again using the newly calculated micrometer setting. A crimp diameter between 1.190 and 1.196 should be 
obtained. If further adjustment is necessary, the same procedure should be followed until the proper crimp diameter is obtained.

NOTE: 

Large size crimps will probably require more adjustment than smaller sizes.

When the correct micrometer setting is found, record it. The next time that style and size of hose is crimped, dial your recorded micrometer 
setting and the first crimp should be good.
