Pneumatic drive. 1 - diaphragm mechanism housing, 2 - seal, 3 • fitting, 4 - cover, 5 - plate, 6 - diaphragm, 7 - end gasket, 8 - diaphragm rod, 9 - gasket, 10 - actuator housing, 11 - support, 12 - lever axis, 13 - all-wheel drive engagement lever, 14 - gasket.
Disassembly
1. Remove the diaphragm mechanism.
2. Remove the all-wheel drive engagement lever from the axle in the actuator housing. Using a punch and hammer, knock the bearings out of the lever.
3. Checking the diaphragm mechanism.
a) Create a vacuum of at least 400 mm Hg (53.3 kPa) on the "A" or "B" connection and make sure that the diaphragm rod moves.
b) Check the full travel of the rod (between points "a" and "b").
The acceptable value is 21 mm
c) At a vacuum of at least 400 mm Hg (53.3 kPa), check for leaks in the diaphragm mechanism (no fluctuation of the pressure gauge needle on the pump).
4. Remove the fittings and gaskets from the cover and body of the diaphragm mechanism.
5. Remove the six bolts, then remove the diaphragm mechanism cover and take out the diaphragm rod.
6. Unscrew the nut and remove the parts from the diaphragm rod.
Assembly
1. Replacing the diaphragm rod seal (if necessary).
a) Using a flat-blade screwdriver, remove the seal from the diaphragm mechanism housing.
b) Using a mandrel and hammer, press in the new seal.
c) Apply grease to the seal lip.
2. Install the parts onto the diaphragm rod and tighten the mounting nut.
Tightening torque: 37 Nm
3. Install the diaphragm rod into the diaphragm mechanism housing so that the rod spline is in the open part of the housing.

4. Install the cover onto the diaphragm mechanism housing and tighten the six mounting bolts.
Tightening torque: 7.4 Nm
5. Install the fittings with new gaskets.
Tightening torque: 37 Nm
6. Press the two bearings into the all-wheel drive engagement lever. Install the lever onto the axle.
7. Install the diaphragm mechanism.
