Hyundai Tucson: Piston

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Engine Mechanical System / Cylinder Block / Piston

  1. Clean the piston.

(1) Using a gasket scraper, remove the carbon from the piston top.

(2) Using a groove cleaning tool or broken ring, clean the piston ring grooves.

(3) Using solvent and a brush, thoroughly clean the piston.

WARNING

Do not use a wire brush.

  1. Check the piston-to-cylinder clearance by calculating the difference between the cylinder bore inner diameter and the piston outer diameter.

Piston-to-cylinder clearance : 0.035 - 0.055 mm (0.0014 - 0.0022 in.)

(1) Using a cylinder bore gauge, measure the cylinder bore diameter at position in the thrust and axial direction.

Cylinder bore diameter : 75.60 - 75.63 mm (2.9764 - 2.9776 in.)

(2) Measure the piston outside diameter at 13.0 mm (0.5118 in.) from top land

(2) Measure the piston outside diameter at 13.0 mm (0.5118 in.) from top land of the piston.

Piston outside diameter : 75.555 - 75.585mm (2.9746 - 2.9758 in.)

  1. Select the piston matching with cylinder bore class. (match classification mark)

Piston-to-cylinder clearance : 0.035 - 0.055 mm (0.0014 - 0.0022 in.)

(1) Check the cylinder bore size mark on the side of the cylinder block.
