PROBLEM

Show/hide table

Dealers should also attempt to identify and notify any customers who have purchased one or more of the lift stands to inspect the affected lift stands as soon as possible. If a lift stand is found to not seat properly and/ or have improper welds, have the customer remove the stand from service and repaired by their dealer.

Inspect all 9U-7489 100 Ton Lift Stands in Dealer Service, Dealer Tool Inventory, and Customer Inventory.

Inspect to see if there is weld present on the top of the 9U-7407 tube assembly (Image 2 and Image 3). If there is weld present on top of the tube, replace the existing 9U-7407 tube assembly with new 9U-7407 tube assembly. If there is not weld present, then the tube assembly is acceptable

Inspect the bottom of the 9U-7407 tube assembly to see if there is a weld present. If there is a weld present then the tube assembly is acceptable (see Image 4). If there is not a weld present (see Image 5) then replace the existing 9U-7407 tube assembly with new 9U-7407 tube assembly.
