Honing or Reboring Cylinders
WARNING: This page is about a different car, the 2003 Suzuki Vitara. However, it is still accessible from the selected car via links, so may be relevant.
- When any cylinder needs reboring, all other cylinders must be rebored at the same time.
- Select oversized piston according to amount of cylinder wear.
Oversize piston specification
- Using micrometer, measure piston diameter.
- Calculate cylinder bore diameter to be rebored as follows.
- D = A + B - C
- D: Cylinder bore diameter to be robored.
- A: Piston diameter measured.
- B: Piston clearance = 0.02 - 0.04 mm (0.0008-0.0016 in.)
- C: Allowance for honing = 0.02 mm (0.0008 in.)
- Rebore and hone cylinder to calculated dimension.NOTE: Before reboring, install lower crankcase and tighten to specification to avoid distortion of bearing bores.
- Measure piston clearance after honing.
