Esteem L4-1590cc 1.6L SOHC 0 MFI 16V (1995)
If any of following conditions is noted, rebore cylinder.
1. Cylinder bore dia. exceeds limit.
2. Difference of measurements at two positions exceeds taper limit.
3. Difference between thrust and axial measurements exceeds out-of-round limit.
Cylinder bore dia. limit : 75.15 mm (2.9586 inch)
Tapper and out-of-round limit: 0.10 mm (0.0039 inch)
NOTE: If any one of four cylinders has to be rebored, rebore all four to the same next oversize. This is necessary for the sake of uniformity
and balance.
PISTONS
-
Inspect piston for faults, cracks or other damaged. Damaged or faulty piston should be replaced.
-
Piston diameter:
As indicated in image, piston diameter should be measured at a position 23 mm (0.91 inch) from piston skirt end in the direction perpendicular to
piston pin.
Piston diameter:
Standard: 74.970 - 74.990 mm (2.9516 - 2.9523 inch)
Oversize
0.25 mm (0.0098 inch): 75.220 - 75.230 mm (2.9614 - 2.9618 inch)
0.50 mm (0.0196 inch): 75.470 - 75.480 mm (2.9712 - 2.9716 inch)
-
Piston clearance:
Measure cylinder bore diameter and piston diameter to find their difference which is piston clearance. Piston clearance should be within
specification as given below. If it is out of specification, rebore cylinder and use oversize piston.
Piston clearance: 0.02 - 0.04 mm (0.0008 - 0.0015 inch)
NOTE: Cylinder bore diameters used here are measured in thrust direction at two positions.
