Converter Turbine Assembly Overhaul
NOTE
Do not disassemble the turbine unless the drive gear or turbine hub must be replaced. If the converter
turbine is damaged, replace the assembly.
To disassemble the turbine, a hydraulic press having a minimum capacity of ten tons, and adjustable
press bed with a 25 In. opening and a pressure gage to assist in determining the rivet staking loads is
required. A reworked turbine assembly must be rebalanced.
(1)
Punch mark relationship of lockup clutch hub and turbine.
(2)
Place base plate J29535-1 on a workbench,
hole side up.
(3)
Place converter turbine assembly, hub side
up, on top of base plate J29535-1.
(4)
Aline the sixteen rivets to the sixteen holes
in the base plate.
(5)
Place guide plate J29535-2, on top of
converter turbine hub. Centrally locate
each rivet in the guide plate holes.
(6)
Install clamping bolt to retain the guide plate, converter turbine, and base plate together. Tighten the bolt to
50 ft lb (68 Nm).
(7)
Place the turbine assembly and fixture in a drill press.
(8)
Place drill guide J29535-5, into guide plate J29535-2. Using a 1/4 in. drill, drill approximately 3/16 in. (4.76
mm) deep.
(9)
Place the drill guide in the next hole. Rotate the guide plate and drill the rivet. Continue until all the rivet
heads have been removed.
Do not use a hammer to remove the rivets.
(10) Place the turbine and fixture in a hydraulic press. Install rivet remover tool J29535-4 into the guide plate.
Press out each rivet.
(11) Remove the guide plate retaining bolt.
(12) Inspect turbine for cracks, distortion and abrasions. If deficiencies are noted, the turbine must be scrapped.
