(2) Measure the dimension A shown in the figure.
(3) Remove the bolt.

(4) Measure the dimension B shown in the figure.
(5) Calculate according to the formula below.

B – A = C (The middle of the under head

length)

C – 4 = D (The lower limit of under head

length)

C – 4.7 = E (The upper limit of under head

length)

(6) Select a band strut whose length should be

between D and E.

Band strut length

mm {in}

(7) Install the selected band strut.

Tightening torque

37—52 N·m {3.8—5.3 kgf·m, 28—38 ft·lbf}

25. Use the following procedure to adjsut the total

end play.
(1) Install the thickest bearing race (2.6 mm

{0.102 in} )to the end cover.

(2) Install the end cover to the clutch component.

(3) Measure the clearance A between transaxle

case and end cover.

(4) Calculate according to the formulas below.

Select an appropriate bearing race whose
bearing thickness matches the calculated
limits.

A – 2.6 mm {0.102} (Bearing thickness) = B
B – 0.25 = C (The lower limit of bearing

thickness)

B – 0.50 = D (The upper limit of bearing

thickness)
