Step 1
Ensure that you have the correct hardware for your installation
and that it all fits properly. Mating parts should line up, bolt
thread pitches and lengths should be appropriate and all the tools
should be the correct type and size and should be at hand. Have
the manufacturer’s installation instructions handy, since there
may be some critical measurements or pieces of hardware required.

Step
2
Drill a hole in the casing to accept a tether pin. Follow the manufacturer’s
instructions for diameter depth and location of the hole. Make sure
it is in the proper orientation relative to the tether block placement
so that the finished installation will be “clocked” correctly.
Insert the tether pin to the correct depth using a press fit. |

Step
3
Check that there are no burrs on the mating shaft and that the shaft
length is correct for the encoder. Ensure that the slotted tether
block is firmly attached to the encoder body and slide the assembly
onto the mating shaft. Rotate the encoder body so that the tether
block engages the pin. Do not bottom out the pin in the tether block.
Leave at least 1/16 inch between the tether pin and the block. Tighten
the shaft clamp on the encoder. |

Step 4
Using a dial indicator on the outside of the encoder body check
the runout as you rotate the shaft by hand. If it exceeds the manufacturer’s
specifications you will need to re-install the encoder (Excessive
runout will cause premature bearing failure.) Otherwise, your installation
is complete.
