2-4 brake

1. Install the clutch plates, drive and driven plates as 

shown in the figure.

2. Using the dial depth gauge and the SST, 

measure clearance between the retaining plate 

and the snap ring.

Note

• When measuring the 2-4 brake clearance, 

do not install the retaining plate in the 

transaxle case.

(1) Position the SST on the surface of the 

transaxle case where it contacts the end 

cover.

(2) Measure the height A between the SST 

surface and the driven plate.

(3) Position the SST on the piston edge of the 

end cover.

(4) Measure the height B between the SST 

surface and the contact surfaces of the end 

cover and transaxle case.

(5) Measure the retaining plate thickness C.

(6) Calculate the clearance using the following 

formula.

Clearance = A – B – C

0.6 — 0.9 mm {0.02—0.04 in}

CONTROL VALVE BODY DISASSEMBLY/ASSEMBLY

AME571421100A01

Caution

•••• Denting or scratching the control valve body components will reduce the ability of the transaxle to 

shift properly. When handling these components or the valve body that contains them, be careful 

not to drop or hit them.

1. Remove the harness clips.

2. Disassemble in the order indicated in the table.

3. Neatly arrange the removed parts to avoid confuse on with similar parts.

Warning

•••• Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. 

Wear protective eye wear whenever using compressed air.

4. Clean the removed parts with cleaning solvent, then use compressed air to dry them. Use compressed air to 

clean out all holes and passages.
