N = 3.10 + (0.52 – 0.30) = 3.32 mm, so we need a valve lifter with identification mark 332. With ERG system: FXE20MR11 (DENSO) Without ERG system: REA12MC4 (DENSO)Ĭalculate the thickness of new adjusting valve lifter so valve clearance comes within specified values. Head tightening procedure and torque specs:ġ5.4 kg/m 2 (15.1 bar, 219 psi) / 200 rpmġ2.9 kg/m 2 (12.7 bar, 183 psi) / 200 rpmĬompression differential limit between cylindersĠ.06 kg/m 2 (0.06 bar, 0.9 psi) / 200 rpm The HR16DE does not have hydraulic lifters, so special valve lifters are used to adjust the valve clearance. Intake valves are 31.0 mm (1.22 in) in diameter, intake duration is 228°, and the exhaust valves are 25.5 mm (1.00 in), exhaust duration is 208°. The HR12DE has variable valve timing system (C-VTC) on the intake camshaft. The cylinder head is made of strong, light aluminum alloy which gives it good cooling efficiency. Number of piston rings (compression / oil): Cylinder block (after 2006)ġ0.7:1 or 12.0:1 (Depends on vehicle model) The crankshaft and camshaft journals are finished with a polishing tape to produce a mirror-like finish. As engines run, they sometimes go out of time, causing a rough idle, loss of power and poor gas. The KA24E came in 2.0- and 2.4-liter versions and was used in many Nissan autos, including: the 240SX, Pathfinder, Stanza and Nissan trucks. Each piston is equipped with two compression and single oil control ring. The KA24E was a workhorse engine in Nissan automobiles from 1988 until 2004. The engine has cracking-processed connecting rods. Cylinders in the Nissan HR12DE engines are fitted at an offset to minimize friction arising from the angle of the connecting rod as a piston descends into the cylinder. The HR12DE has an aluminum cylinder block with four bearing support system. General information Engine Specificationsġ03 Nm (10.5 kg Engine: 4 Cyl 2.4L, 4 Cyl 2.5L Diesel, 6 Cyl 3.0L. Parts fit for the following vehicle options. Inside forged crankshaft was installed with 96 mm piston stroke, and also 165 mm forged connecting rods. It used 4-cylinder inline cast-iron cylinder block with cylinder diameter 89 mm. The first version of the engine was KA24E. KA24 appeared in 1988 as substitution to Z24. Distributor & Ignition Timing Sensor are shipped directly from authorized Nissan dealers and backed by the manufacturers warranty. Nissan KA24DE engine reliability, problems and repair.
