15) Mount the standoff block to the replacement bearing cart, in precisely the same

location and orientation as the original. Make sure that the block is mounted on the

same side as the eccentric-adjustable bearings. Tighten both recessed bolts very

securely when the block is perfectly aligned to the bearing cart.

16) Loosen both of the

eccentric pivot locking

set screws, ~1 turn

each with a 2mm Allen

wrench. Slide the

bearing cart / standoff

block assembly onto

the top rail of the

machine, with the

standoff block facing

the front.

17) Using a 5mm Allen

wrench, tighten both of

the eccentric bearing

axles until the bearings

feel properly snug on the

rails, then tighten each of

the 2mm set screws.

Slide the cart back and

forth to check for proper

alignment and rolling

movement on the rails.

Loosen the set screws

and re-adjust the

eccentric pivot axle(s) if

necessary, then re-

tighten both set screws

securely.
