Genie 33224A.S Chain Guide B Spacer Replacement Details

Technician Note
If a spacer is missing, the chain guide may sit out of position and wear quickly. Check the guide, chain stripper, fasteners, and rail channel at the same time. A new spacer will not correct a bent rail or severely loose chain.
Before Ordering
- Confirm the original spacer part number is 33224A.S
- Verify the opener rail diagram shows this spacer at Chain Guide B
- Check whether the chain guide itself also needs replacement
- Inspect the rail channel and chain tension before reassembly
- Do not replace a washer or chain stripper with this spacer unless the diagram confirms it
Professional Advisory
Rail hardware should be serviced with the opener disconnected from power and the garage door in the closed position. If the chain has derailed or the door moves poorly by hand, have the full door and opener system inspected before returning it to service.
