The wheel I have in this demo is a Double Treadle RoadBug made by The Merlin Tree
These are the tools I used - A phillips screwdriver, a pipe wrench (simply to help unscrew the main shaft), a ratchet and a 1/2" socket.
Step 1: Remove Treadles From Drive Wheel
Step 2: Remove Treadles From Body
Step 3: Remove Mother-Of-All
The spring isn't tensioned on this hinge. It mainly serves to support and balance the Mother-of-All.
Remove the Top hinge very carefully. This spring is under a lot of tension and will throw your screws all over the living room and make them impossible to find and could also possibly pinch your fingers.
Step 4: Unscrew the Main Nut From the Shaft
** Be sure to hold both the crank piece and the wheel from turning. If the wheel turns and the crank is held while removing the lock nut the bearings will get crushed.

Step 5: Remove Footman Assembly (Double Treadle Models Only)
Step 6: Remove Wheel From Body
**Note - in the second picture, I've turned the wheel around to the other side because I'm right-handed so this is what you would see if you were facing the back of the wheel body. ** Sorry for any confusion.
Step 7: Remove Bolts From Drive Wheel
**On my wheel, there is a spacer that appears to be glued to the drive wheel itself. I just stained around this instead of prying it off with a screwdriver and scratching up the wood.
Step 8: Get Messy!
If you want to do it like I did, make sure to use the stickiest stain possible and get it all over your hands and clothes and whatever you do don't be patient and prepare your surfaces by sanding them or waiting for the first coat of stain to dry before applying the second.**
**Don't do that at all. But do proceed to Step 9.
Step 9: Re-Assemble and Use Loctite Blue 242 on the Main Bolt
Proper Treadle-Crank Setting
**This step is critical for proper treadling as the two treadle attachments must be slightly off dead opposite.
Screw the crank arm extension back on to the wheel axle until snug but not restrictive of wheel rotation. With slight turning align the crank to 175 degrees or 185 degrees of the crank (footman post) on opposite side. In other words, if the right side footman post is down at 6 o’clock the left side crank end should be at 11:30 or 12:30, not directly opposite.
If the crank is not in the correct position, unscrew, tap axle back, rotate axle 90 or 180 degrees and tap back in. Remember that the axle is a carriage bolt and has a square base under the head - the bolt can be put in in four positions.
But I did one extra thing and applied Blue Loctite 242 onto the main bolt before I tightened the main nut to keep it from loosening from the vibration of using the wheel and transporting it all over town.
Dave, you make a wonderful wheel and we appreciate everything you have done for our community:)
