Frequently Asked Questions
Look up your exact model/serial in the Graco parts manual and verify that 103420 Pin, Spring is listed for the relevant assembly position. If it is listed, this is the correct OEM part.
Using a non-OEM pin risks improper preload, premature wear, or unsafe retention. For best results, use the genuine Graco 103420 part specified in the manual.
It commonly appears in linkage, wheel/axle, or hitch-style assemblies where a spring-tensioned pin holds components in place while allowing service access.
No—this is a slip-in spring pin, not a torque-to-spec fastener. Ensure proper seating and that the spring retention is functioning as intended.
Replace if you notice bending, corrosion, loss of spring tension, or looseness in the assembly the pin secures.
