Supersession boundary

An earlier L11845-1 listing is described by a third-party distributor as changed to L11845-3, but Lincoln first-party confirmation was not found; no supersession claim is proposed.

Before you order

1. Record the complete machine model and code number.
2. Confirm that the Lincoln parts record for that exact code calls for L11845-3 or SKU 9SL11845-3.
3. Match every suffix and revision character; nearby base numbers may identify a different assembly.
4. If the removed part has a different number, pause and verify the relationship before purchase or installation.
