Replacement of the magnet-style sensor disk is simple and the process is identical for any Hybrid Series rower equipped with older-style A1 QuickStart and A1 Pro Monitors. Follow the steps below.
Step 1
Detach the top deck from the tank assembly by unscrewing the upper tie rod bolts and the top deck JCBs.
Note: When removing the tie rods, a barrel nut from under the top deck will come out. Keep for reassembly.
Step 2
Gently lift the top deck, taking care not to dislodge the guide pulleys.
Set the top deck to the side (do not disconnect the sensor wires). Remove the sensor disk from the paddle shaft.
Note: If you have trouble removing the sensor disk, you may need to pry it up with a pair of pliers or channel locks.
Step 3
With the silver magnets facing upwards, place the new sensor disk onto the paddle shaft.
Be sure to push the sensor disk down until the base of the sensor disk is fully recessed into the clutch. If the disk is sitting too high, it will crack due to excess pressure.
Step 4
Re-attach the top deck on the tank assembly by securing it with the JCBs and tie rods / barrel nuts.
Note: The barrel nuts have a slot in the bottom that aligns with the hole the tie rod bolts screw in to — this will assist you with installation.
