Usage:
The original "D8" and "D9" Return Line Assemblies (tools with the identification of "D" are not any relation to the tractor models) in some applications make installation of the tee-test flow block very difficult.
Two additional return assemblies, FT1633 and FT1634 will permit easier installation of the tee-test flow block. FT1633 and FT1634 are made from the same component as the "D8" and "D9" assemblies except for the 90° elbow, which is not used. See Illustrations 1 and 2.
The FT1633 and FT1634 Assemblies can be used in any tee-test application where return oil from the flow block must be returned into the hydraulic tank filler opening.
In the Tee-Test Tool Chart in the Tool Guide, FT1634 Assembly will be referred to as "D11". FT1633 will be referred to as "D12".
