How To... Replace and Adjust Seat Rollers
Special Service Tools: NONE
Note:The seat rollers are adjusted to a
specified resistance load. If the seat moves too
freely with excessive side-to-side movement,
then the seat rollers must be adjusted as
follows.
1. Using a ½ inch wrench, loosen all four(4) seat
roller clamp nuts, then retighten by hand.
NOTE: In this step, you must make initial
adjustments to the seat rollers on the right side of
the unit first. This is done to insure that the two
right guide rollers are properly seated in the V-
channel of the seat extrusion. Once the seat rollers
on the right side are adjusted, then proceed to
adjust the seat rollers on the left side of the unit.
The following requires use of two, inch pound
torque wrenches. One to maintain a resistance
load against the take-up roller and the other to
torque the roller clamp nut.
2. Starting with the right side seat rollers, adjust the
first take-up roller nut to 60-65 in. lbs. in a
clockwise direction. Observe that the roller clamp
nut will move up. This indicates that the seat roller
is being forced up against the extrusion. Continue
to maintain the 60-65 in. lbs. resistance load on
the take-up roller, and secure the seat roller
position by tightening the roller clamp nut from
100-120 in. lbs. Repeat this procedure for other
remaining right roller. Once the right side is
adjusted, repeat this procedure for the left side.
Always set the right side seat rollers first. Failure
to do so, will result in side-to-side seat movement.
3. With all seat rollers adjusted, test operation of the
seat assembly for a 15-25 lbs. pulling force and to
insure that no side-to-side movement exists.
Repeat this procedure as required.
