Description
4247 007 1001 STIHL Linch Pin Set Genuine OEM Pump Retaining Pin Kit
The STIHL Linch Pin Set (4247 007 1001) is a genuine OEM retaining pin kit designed for select STIHL sprayers, including the SG 20 model. This linch pin set is used within the pump assembly to secure critical pump components in place, ensuring proper alignment and reliable operation during spraying applications.
Linch pins are small but essential fastening parts that prevent components from shifting or disconnecting under pressure and repeated pump movement. Over time, retaining pins may wear, bend, corrode, or become lost during service. A missing or damaged pin can lead to pump instability, improper operation, or potential component failure.
Replacing the linch pin set with the correct genuine STIHL OEM part restores proper pump retention, safe assembly integrity, and reliable sprayer performance without replacing the complete pump unit.
Manufactured to STIHL factory specifications, this OEM pin set ensures precise fitment, secure locking strength, and long-term durability under demanding agricultural and landscaping conditions.
