Sidekick JSS 4D Hard Top 2WD L4-1.8L (1997)
-
If ring gear is damaged, cracked or worn, replace flywheel.
-
If the surface contacting clutch disc is damaged, or excessively worn, replace flywheel.
-
Check flywheel for face runout with a dial gauge. If runout exceeds its limit, replace flywheel.
Limit On Runout: 0.2 mm (0.0078 inch).
Cylinder Block
Distortion of gasketed surface.
-
Using straightedge and thickness gauge, check gasketed surface for distortion and, if flatness exceeds its limit, correct it.
Flatness Limit: 0.06 mm (0.0024 inch).
Honing Or Rebating Cylinders
1. When any cylinder needs reboring, all other cylinders must also be rebored at the same time.
2. Select oversized piston according to amount of cylinder wear.
Size: Standard
Piston Diameter: 83.970 - 83.990 mm (3.3059 - 3.3066 inch).
Size: O/S 0.25
Piston Diameter: 84.220 - 84.240 mm (3.3157 - 3.3165 inch).
Size: O/S 0.50
Piston Diameter: 84.470 - 84.490 mm (3.3256 - 3.3263 inch).
3. Using micrometer, measure piston diameter.
4. Calculate cylinder bore diameter to be rebored as follows:
D=A+ B-C
D: Cylinder bore diameter to be rebored.
A: Piston diameter as measured.
