1. Locate the Eccentric Bearings
Locate the two eccentric bearings on the Trolley. The eccentric bearings are located on the
right side (the side opposite of the Cable Track) of the Trolley. The bearings on the left side of
the Trolley are fixed. Place the thin wrench supplied with the Dragon on the adjustment flat of
the eccentric bearing, located between the bearing and underside of the Trolley.
Important
In older belt driven Dragon machines, the eccentric bearings are located on the
left side (the side with the Cable Track) of the Trolley.
2. Loosen the Front Eccentric Bearing
Use a ¾ in. wrench to loosen the front eccentric bearing mount nut on the top side of the
Trolley Base Plate. Loosen the bearing mount nut just enough to allow adjustment of the
bearing using the flat wrench. Adjust the bearing so the Trolley rides smoothly along the Rail
with minimal effort and no rocking.
Note
Eccentric Bearings are off center bearings. It is best to adjust the eccentric bearings when they
are in the closest position to the rail. Once the bearing is loose, rotate it and adjust it to the
tightest position.
3. Loosen the Rear Eccentric Bearing
Use a ¾ in. wrench to loosen the rear eccentric bearing mount nut on the top side of the
Trolley. Loosen the bearing mount nut just enough to allow adjustment of the bearing using the
flat wrench. Adjust the bearing so the Trolley rides smoothly along the Rail with minimal effort
and no rocking.
4. Re-tighten the Bearing Mount Nuts
The bearings may need to be adjusted multiple times in order to achieve optimal Trolley
operation.
Once the eccentric bearings are adjusted so the Trolley rides smoothly along the Rail with no
rocking or binding, tighten the eccentric bearing mount nuts, then tighten another quarter turn.
