Frequently Asked Questions
Check your sprayer’s parts manual or exploded diagram for the wheel/axle section. If the listing shows 101242 (often noted as Ring, Retaining, External), this is the correct part. If unsure, provide your model number to confirm.
Use retaining-ring pliers sized for the ring. Clean the axle groove and lightly deburr if needed. Compress the ring evenly and ensure it snaps fully into the groove—partial seating can cause wheel looseness.
Wobbling wheels, side-to-side play, or visible gaps at the axle groove are common signs. If the ring is cracked, deformed, or missing, replace it immediately to avoid cart damage or unsafe handling.
