How to adjust the reformer side wheels

It may be necessary to adjust the reformer's side wheels to achieve optimal carriage performance.

Tools:

  • 10mm open-end wrench (or 10mm socket and ratchet)

  • 4mm allen wrench

Preparation:

  • The springs and shoulder rests are removed from the carriage
  • The carriage is removed from the reformer frame and placed upside down on a clean padded surface to protect the upholstery from damage

Removal:

Insert the 4mm allen wrench key into the head of the black M6 bolt located in the center of the wheel.

Using the 10mm wrench, grip the M6 nut underneath the bracket that the wheel is mounted to.

Turn the allen wrench counterclockwise until the nut is completely loosened and removed from the bolt.

Remove the wheel, bolt and washers from the bracket.

 
Figure 1
Assembly:
 

Insert the bolt through the bearing in the wheel. DO NOT install a washer between the bolt head and the bearing.

Install 3 washers on the bolt and slide up next to the wheel bearing.

 

SideWheel Adjustment

Insert the wheel, bolt and washer assembly into one of the other 4 holes in the bracket.

A. If the carriage is too tight between the rails (ie. all 4 wheels in constant contact with the side rails) choose a hole closer to the centerline of the carriage.

B. If the carriage is too loose (ie. too much side - side travel of carriage between the side rails) choose a hole further away from the centerline of the carriage.

***The updated mounting bracket now has 5 hole positions instead of the original 3 shown in this document. The ‘as shipped’ position is the middle or 3rd hole in the bracket. This leaves 2 adjustment positions in both directions to either increase or decrease the amount of side - side travel of the carriage. Ideally the wheels should be adjusted slightly narrower than the space between the rails to allow free movement of the carriage.***

Install a washer and the nut as shown in Figure 1. Thread the nut on by hand until you feel it stop turning.

Using the allen wrench and open end wrench tighten the nut and bolt firmly.

Repeat for the other side wheels.

Note: It is highly recommended that each side wheel is mounted in the same hole position to keep the carriage centered on the reformer.
