Marantec 73636, Clevis Pin for All Belt and Chain Rails
The Marantec 73636 clevis pin is used in compatible Marantec rail and door-arm connection points where a removable pin is required to secure mechanical linkage. Although it is a small part, the clevis pin is critical because it keeps the connected rail, trolley, or arm hardware locked together during opener travel. A missing, bent, or incorrect pin can create sloppy movement, rattling, uneven pull, or a disconnected opener arm. Customers often need this part after a rail repair, trolley replacement, header bracket service, or missing-hardware issue. It should be matched by connection style and original part number because Marantec used different hardware across standard, heavy duty, belt, chain, residential, and light commercial rail systems.

Technician Note
If a clevis pin is missing, also check for a missing retaining clip or a worn hole in the bracket or trolley. A new pin will not safely hold if the connected bracket has become elongated or damaged.
Before Ordering Checklist
- Match the pin location on the rail or arm assembly.
- Confirm the parts diagram lists 73636.
- Check that the retaining clip or keeper hardware is also present.
- Inspect the bracket holes for wear before installing a new pin.
- Do not substitute a loose bolt, nail, or non-rated hardware in place of the correct pin.
Professional Advisory
A garage door opener arm connection carries moving load. If hardware is missing or the door arm disconnected during operation, inspect the door balance and bracket condition before reconnecting the opener.
Product Questions & Answers
Where is the Marantec 73636 clevis pin used?
It is used at compatible Marantec rail, trolley, header bracket, or door-arm connection points where the parts diagram calls for 73636.
Is this pin universal for all Marantec openers?
No. It should be matched to the specific rail hardware diagram and connection point.
Does 73636 include the retaining clip?
Package contents can vary by listing. Treat it as the clevis pin unless the product listing or inventory confirms additional hardware.
Can I replace a missing clevis pin with a regular bolt?
