D. If you are replacing the drive belt, slip the drive belt off the front roller pulley and
discard it.
7. Attach the front roller.
A. Slide the new drive belt around the front roller.
B. Using a 9/16" socket wrench with a 3" extension, insert the two screws that fasten the
front roller to the frame. NOTE: Tighten each of the two screws evenly, making sure
not to tighten one screw too many turns before moving to the other screw. See Figure 8.
8. Secure the rear roller bolts.
A. Using a 3/4" socket wrench, tighten each rear roller bolt evenly, making sure not to
tighten either bolt too many turns before moving to the other bolt. NOTE: Do not
overtighten the belt. You will tension and center the belt in step 23C.
NOTE: If you are replacing the motor with a new one follow step 9. If not, skip to step 10.
9. Transfer the flywheel to the new motor.
A. Using a 7/16" socket wrench,
remove the flywheel, screw,
washers and motor (ansi
square) key from the old motor.
See Figure 14.
B. Place the flywheel in position on
the new motor and slide the
motor key into the slot on the
flywheel. See Figure 14.
C. Using a 7/16" socket wrench,
install the flat washer, split
washer and screw that hold the
flywheel on the motor and then
tighten securely (80 in-lbs). See
Figure 14.
Motor Brushes
NOTE: Motor brushes are wear items that will periodically need to be replaced. Both drive
motor brushes must be replaced as a pair. This will ensure even commutator contact
and brush wear. However, the one brush may wear faster than the other brush.
Therefore, always measure both brush lengths to determine whether you should
replace the pair. Check both brushes for cracks or chips.
NOTE: When "Err9" appears on screen it indicates motor brush wear. The treadmill will run
100 miles (161 kilometers) longer and then be inoperable until brushes are replaced.

I have a Trotter MG 2100 machine and the seat adjustment pin came out and I can’t get it to engage. This would be the seat where you do the shoulder press and lat pull down exercises. I have taken the back Support seat off so I can see the hydraulic cylinder. I don’t see anything through the slot where the pin would go to have it catch anything. Right now the cylinder just goes up and down, but can only be used in the farthest down position as there is no locking mechanism for the cylinder. Thank you for any help you can provide!
To fix the seat adjustment mechanism on a CYBEX TROTTER MG 2100 after the adjustment pin came out, follow these steps:
1. Locate the adjustment pin on the side of the seat or seat back.
2. Align the seat or seat back to the correct position where the pin should lock in.
3. Reinsert the pin through the adjustment hole and into the frame to secure the position.
4. Ensure the pin locks firmly in place.
The adjustment mechanism is simple and uses a pull pin system. If the pin is damaged or missing, replace it with a compatible one to restore full function.
