An auxiliary wedge apparatus (36) configured to couple to the restrainer bracket (28B) of a jet pump assembly (10) is described. In one embodiment, the auxiliary wedge apparatus (36) includes a support block (38) configured to couple to the restrainer bracket (28B), and a wedge (40) configured to slidingly couple to a wedge channel (42) in the support block (38), and to engage the inlet mixer (16B) to restore a tight rigid fit-up of the jet pump (10) components. The support block (38) includes a wedge channel (42) having tongues (72A, 72B) depending from the parallel sides (70A, 70B) of the channel (42) and a hook shaped portion (52) configured to receive the restrainer bracket (28B). The support block (38) also includes a lock screw (56) to couple the support block (38) to the restrainer bracket (28B). The wedge (40) includes grooves (76A, 76B) in the parallel sides (78A, 78B) of the wedge (40) configured to slidingly engage the tongues (72A, 72B) extending in the wedge channel (42). The auxiliary wedge apparatus (36) also includes a restraint arm (44) depending from the support block (38) configured to capture the existing set screw (32C) in the restrainer bracket (28) to prevent the screw (32C) from completely unscrewing. <IMAGE> |
