Snap Ring Installation Instructions for John Deere 2500, 2500E and QA5
(Use Page 12 as a Parts Reference)
The following instructions may be used for replacing your coupler, or adapting your unit to a John Deere 2500:
1. Turn the roller unit upside down.
2. Remove the belt guard (31P-VR7002-1) and the belt (37P-7121).
3. Loosen the set screw on the 5" pulley (37P-7100), and remove the pulley.
4. Loosen both set screws on the bearing (37P-7101) and the lock collar on the bearing (37P-7102).
5. Insert a punch into the hole in the lock collar and tap it in the opposite direction it will rotate, to loosen the
eccentric grip on the shaft, and slide it free of the bearing.
6. If the snap ring on the bearing is on the outside of the unit, use a rubber mallet to tap the shaft towards the
motor end until the snap ring can be removed. Then tap it back in the opposite direction until it is free of the
bearing (37P-7101). In other cases, a socket or a tube – slightly under 1 inch diameter – can be used to tap
shaft towards the belt side of the roller until it is free of the bearing (37P-7101).
7. Lift the coupler end of the shaft. The bearing (37P-7102) will pivot within flange until it can be pulled from
bearing.
8. Use a 1/4" punch and drive out the roll pin joining the coupler and the shaft, and remove the coupler. NOTE:
A punch can be used inside the spline to tap the shaft free on internal spline couplers. However, external
splines may require a light heat application to aid in removal.
9. Install the new coupler to the shaft; a light oil or anti-seize may be used. Make sure the holes align, tap them
together, and install the new roll pin.
10. Install the snap ring (37P-1029) into the coupler groove and slide the shaft back into bearing (37P-7102).
Push the shaft back down and align it with the center of the bearing (37P-7101), then insert it into the bearing.
11. Slide the shaft into the bearing (37P-7101) until the snap ring is tight against it. Next, tighten the bearing set
screws.
12. Slide the lock collar up to the bearing (37P-7102); be sure the recess of the lock collar fits over and engages
the hub on the bearing. Turn the lock collar in the direction the shaft will rotate until it is snug. Then, using a
punch and hammer, give the lock collar one good tap in that same direction to lock the bearing, collar and
shaft together. Finally, tighten the set screw.
13. Install the pulley (37P-7100) and the belt (37P-7121). Align the belt and tighten the set screw.
14. Replace the belt guard (31P-VR7002-1) and tighten.
15. Install the internal spline coupler adaptor.
16. Align the motor splines, slide and twist the motor into place, and tighten the mounting bolts.
