How to Replace Your Volute Spring
Step 1: Remove the pedals (Part 49L/R) with a metric 19 wrench.
Step 2: Remove the screws (Parts 11 & 12) from the covers with a Philips screwdriver.
Step 3: Remove the securing screw (Part 16) for the tension knob to the right-side cover.
STEP 3A: Remove the computer wire from the meter.
Step 4: Remove handlebar grip. Use soapy water as lubricant if needed. Remove the strap from the exposed handlebar and let it back into the volute spring by hand.
Step 5: Walk the belt off the pulley on the volute spring. Method shown in the video below.
Step 6: Remove the outer securing nuts with a wrench metric 15 for the volute spring assembly and pull your old assembly out of the frame of the rower.
Step 7: Install the new volute spring assembly through the drive belt and into the frame. Make sure the inner nuts on that assembly are up against the inside of the frame on both sides.
Step 8: Secure down the outer nuts on that volute spring assembly. Clamping the frame between the inner and outer securing nuts.
Step 9: Pull the strap for the handlebars up and through the pulley/frame and install the strap onto the handlebar.
NOTE: (If you do not feel tension fighting against you, we will have to rewind the spring assembly as shown in the video below. This volute spring assembly is not the resistance provider, it is only responsible for recoiling the strap and holding up the handlebars. Over tensioning this spring can cause damage to the part.)
