Disassembly and Assembly

DISASSEMBLE

CAUTION: All parts must be handled carefully to avoid nicking or burring the bearing or mating surfaces. Lubricate all internal parts with clean automatic transmission fluid before assembling them. Do not use any other lubricants except on gaskets and thrust washers. These may be coated with petroleum jelly to facilitate assembly. Always use new gaskets and seals when assembling transmission.

Drivetrain Disassembly:

1. Separate drive train as shown in the Drivetrain Disassembly image.

Removing Reverse-High Clutch Pressure Plate Snap Ring:

2. Remove pressure plate snap ring from clutch.
3. Remove clutch parts.

Removing Reverse-High Clutch Piston Snap Ring:

4. Install tool shown in the Removing Reverse-High Clutch Piston Snap Ring image or its equivalent on clutch drum. Ensure legs clear snap ring enough to permit expanding it for its removal. Remove tool after snap ring has been removed.

Reverse-High Clutch Disassembled:

5. Remove spring retainer and piston return springs.

Removing Reverse-High Clutch Piston Bushing:

6. Apply air pressure to piston apply hole in clutch hub and remove piston.
7. Remove piston outer seal from piston and inner seal from clutch drum.

Bushing Replacement

Replacing Reverse-High Clutch Rear Bushing:

1. To replace the rear bushing, position the clutch housing in a press and remove the bushing as shown in the Replacing Reverse-High Clutch Rear Bushing image.
2. To remove the front bushing, use a cape chisel and cut along the bushing seam until the chisel breaks through the bushing wall. Pry the loose bushing ends up and remove the bushing.

Installing Reverse-high Clutch Front Bushing:

3. To install the front bushing, press it into the housing as shown in the Installing Reverse-High Clutch Front Bushing image.

ASSEMBLE
1. Dip new seals in transmission fluid and install one on drum and one on piston. Install piston in clutch drum.
2. Place return springs in piston pockets. Place retainer on springs.

NOTE: Return springs must be placed in sockets.

3. Compress springs with tool shown in the Removing Reverse-High Clutch Piston Snap Ring image. Make certain that spring retainer is centered while compressing springs. Install snap ring. Before releasing pressure on tool, see that snap ring is positioned inside four snap ring guides on spring retainer.
4. Dip clutch plates in transmission fluid. Install clutch plates alternately starting with a steel drive plate and a composition plate, as shown in the Reverse-High Clutch Disassembled image.

NOTE: If new composition plates are to be used, they should be soaked in transmission fluid for 15 minutes prior to assembly.

5. After all the clutch plates have been installed, position pressure plate in clutch drum. Install pressure plate snap ring.

Checking Reverse-high Clutch Snap Ring Clearance:

6. With feeler gauge, check clearance between pressure plate and snap ring. Pressure plate should be held down as clearance is checked. Clearance should be 0.022-0.036 inch. If clearance is not within specifications, selective thickness snap rings are available in thicknesses of 0.056-0.060 inch, 0.065-0.069 inch, 0.074-0.078 inch, 0.083-0.087 inch, 0.092-0.096 inch, 0.110-0.114 inch and 0.128-0.132 inch.
