Installation
1. INSTALL STARTER ASSEMBLY
(a) Install the starter with the 2 bolts.
Torque: 37 N*m (380 kgf*cm, 26 ft.*lbf) for bolt
(b) Connect the starter connector.
(c) Install the terminal nut and cover the nut with the
cap.
Torque: 9.8 N*m (100 kgf*cm, 7 ft.*lbf) for nut
2. INSTALL NO. 1 ...
Inspection
1. INSPECT FRONT SPEED SENSOR
(a) Make sure that there is no looseness at the
connector lock part and connecting part of the
connector.
(b) Disconnect the speed sensor connector.
(c) Measure the resistance between terminals 1 and 2
of the speed sensor connector.
OK:
Resistance:
0.92 ...
Reassembly
1. APPLY HIGH TEMPERATURE GREASE
(a) Apply the high temperature grease to the surface on
which the shoe and backing plate attach.
2. INSTALL PARKING BRAKE SHOE LEVER LH
(a) Install the shoe lever and shim to the rear shoe with
a new C-washer.
(b) Using a feeler gauge, measure the clearance.
