Overview
This procedure is designed to resolve issues where the arm shaft of a Rogue Echo Bike has been smashed in, which typically occurs during shipping. By following these steps, you can correctly pull the shaft back out and replace the spacer assembly.
Number of Steps: 9 steps .
Issue: Arm shaft smashed in during shipping.
Required Tools:
3mm Hex/Allen key.
6mm Hex/Allen key.
Rubber mallet (or hammer with a protective wooden block).
Detailed Instructions
Remove Foot Pegs: Use a 6mm Hex key to remove the foot peg on the affected side(s).
Remove Arm: Unscrew and completely remove both arm clamp bolts. Pull the arm off the shaft, rocking and shaking it if it sticks.
Replace Spacer: Remove the thick broken spacer. Leave the thin spacer in place; these are about the thickness of a fingernail and may be stuck to the bearing. Install the new spacer, but do not tighten the set screw yet.
Pull Shaft Out: Place the arm back on the shaft without the clamp bolts. Take the large foot peg bolt and washer and screw them into the arm shaft until the bolt is tight to pull the shaft out.
Add Set Screw: Repeat steps 1 and 2 to remove the arm and foot peg bolt again. Clock the spacer until its set screw hole lines up with the hole in the shaft, then screw the set screw in tightly.
Reinstall Arms (Alignment): Turn the pedal cranks until they are in line with the linkage from the pedals to the arms inside the fan cage. This ensures both arms are in the vertical position for mounting.
Install Arm: Align the slot in the arm clamp with the white line painted on the spline shaft. Hold the arm vertical and push it onto the shaft, moving it gently back and forth until it slides on with about 1/8" (3-4mm) protruding. Tap the arm fully flush using a rubber mallet.
Clamp Arms: Secure the arm with the two provided M8 bolts and lock washers. Tighten these significantly to ensure there is no free play or movement.
Install Foot Pegs: Reassemble the foot peg by inserting the bolt through the peg, sliding on the cylinder spacer, then the washer. Screw this assembly into the end of the arm shaft and tighten until snug.
Key Details and Safety Notes
Tolerance: The splined shafts are machined to a very tight tolerance and the arm will only mount when perfectly aligned.
Component Damage: Never hit the arm directly with a hammer; always use a rubber mallet or a protective wooden block to prevent damage.
Thin Spacers: Be careful not to lose or double-up thin spacers that may be stuck to the bearing surface.
Maintenance and Care
Tightness Check: Periodically check the arm clamp bolts (M8) to ensure they remain tight and there is no "play" in the handle arms during use.
Foot Peg Security: Ensure foot peg bolts remain snug to prevent them from backing out during high-intensity workouts.
Frequently Asked Questions
Q: Why is the handle arm sticking when I try to pull it off? A: The splined shaft has a tight tolerance; rocking and shaking the arm gently while pulling will help release it.
Q: How do I pull the shaft back out if it was pushed into the frame? A: Use the foot peg bolt and washer as a puller by screwing them into the shaft through the arm until they pull the shaft into the correct position.
Q: What is the white line on the spline shaft for? A: This is an alignment mark that should be lined up with the slot in the arm clamp to ensure the arm is correctly clocked.
Q: How do I know the arm is fully installed? A: The arm should be tapped with a mallet until it sits completely flush against the spacer.
