ON-VEHICLE MAINTENANCE B CRANKSHAFT POSITION SENSOR DRIVE GROOVE 45UOBX-04 Removal Note Camshaft pulley 1. Hold the camshaft with a wrench at the cast hexagon. 2. Remove the camshaft pulley lock bolts. 3. Remove the camshaft pulleys. Camshaft 1. Loosen the camshaft cap bolts in two or three steps in the order shown in the figure. 2. Remove the camshaft caps. 3. Remove the camshafts. 4. Remove the camshaft oil seals from the camshafts. HLA Caution The HLA must be reinstalled in the same posi- tions from which they were removed. If they are not, it can cause premature and uneven wear. Note Mark the HLA to show their original positions. Remove the HLA from the cylinder head. Installation Note HLA 1. Apply clean engine oil to the friction surfaces. 2. If the HLA are being reused, install them in the position from which they were removed. 3. Verify that the HLA move smoothly in their bores. Camshaft Note The exhaust camshaft has a groove for the crank- shaft position sensor drive. 1. Apply clean engine oil to the camshaft journals and bear- ings. 2. Install the camshaft in position.

B ON-VEHICLE MAINTENANCE I - DOWEL PINS I 3. Apply silicone sealant to the shaded areas shown in the figure. Do not let any sealant get on the sealant surfaces. 4. Install the camshaft caps according to the cap number and arrow mark. 5. Install the camshaft cap bolts and tighten them in two or three steps in the order shown in the figure. Tightening torque: 11.3-1 4.2 N.m (115--145 kgf.cm, 100-125 in-lbf} ii 6. Apply a small amount of clean engine oil to the lip of a new camshaft oil seal. 7. Push the oil seal slightly in by hand. 8. Using a pipe and hammer, tap the oil seal in evenly until it is flush with the edge of the camshaft cap. Note Oil seal outer diameter: 48mm {I .89 in) Oil seal inner diameter: 34mm {I .34 in} Camshaft pulley 1. Turn the camshafts until the camshaft dowel pins face straight up. 2. Install the camshaft pulleys with the I mark (intake side) or the E mark (exhaust side) straight up. Gartner Banana
