Fitment Guidance

  • Confirm using your gun’s parts diagram: look for part no. 101804.
  • Do not substitute other pins (e.g., different length/head style) unless the manual explicitly allows.
  • Replace worn or damaged pins to prevent trigger play, premature wear, or misalignment.

Frequently Asked Questions

Open your model’s service manual or parts list and look for the exact part number 101804. If it’s listed against the trigger/pivot assembly, this pin is the correct replacement.

Not necessarily. Graco uses different pins (sizes, head styles, locations). Always match the part number. A look-alike pin with a different number may not seat correctly or meet the required length/thread specification.

Work on a clean bench, relieve pressure, and follow the gun’s disassembly steps. Inspect related parts (trigger, pivot, bushings) and replace worn items together to maintain alignment and smooth trigger action.

Use the exact part number specified for your model. If your list shows a different pin (or a supersession), order that one instead. Contact support with your full model/series and serial range if unsure.
