Installation (All Models) Mazda MX-5 NB рестайлинг

1. Position notch on crankshaft sprocket to 12 o'clock position (aligned with mark on oil pump). see scheme 3 Align timing marks on camshaft sprocket(s). Timing mark on intake camshaft sprocket is an "I"; timing mark on exhaust camshaft is an "E".
2. Install timing belt tensioner spring with damper rubber closing face away from tensioner. (Scheme 5) Temporarily secure the timing belt tensioner with tensioner spring fully expanded.
3. Install timing belt around crankshaft sprocket, then working in a counterclockwise direction, route belt around idler pulley, camshaft sprocket(s), and tensioner pulley. Ensure there is no slack in belt between crankshaft sprocket, idler pulley, and camshaft sprockets.
4. Temporarily install the crankshaft pulley boss and bolt. Rotate crankshaft about 2 turns in direction of normal engine rotation. Align timing belt pulley boss mark with tensioner set mark for correct timing belt tension adjustment. (Scheme 6)
5. Holding crankshaft stationary, remove the crankshaft pulley boss and bolt. Ensure the crankshaft and camshaft timing marks are still aligned. Loosen timing belt tensioner lock bolt to apply tension to timing belt. Without moving tensioner, tighten tensioner lock bolt to specification. See «TORQUE SPECIFICATIONS»(ref-155942-S04929083372003063000000).
6. Install crankshaft pulley boss, and final tighten bolt to specification. Rotate crankshaft 1 5/6 times. Camshaft timing marks should be aligned with marks on rear cover, and the crankshaft pulley boss locating pin should point straight up. If timing marks are not aligned, remove belt, realign all timing marks, and repeat installation procedure.
7. Check timing belt deflection with 22 lbs. (10 kg) of pressure applied to belt. (Scheme 7) Ensure timing belt deflection is.35-.45" (8.5-11.5 mm).
8. To install remaining components, reverse removal procedure. While installing valve cover gasket, apply light bead of silicone sealer to 6 corners where gasket meets ends of camshafts. Tighten all valve cover bolts in the correct sequence. (Scheme 8)
9. On MX-5 Miata, install OCV case using several steps to tighten bolts to specification in the sequence shown. (Scheme 9) Install OCV filter so that it aligns with the projected part on flange end of oil pipe. (Scheme 10) Apply engine oil to new washer. Temporarily install upper and side oil pipe.
10. Using several steps, tighten top oil pipe bolts in the sequence shown. (Scheme 11) Temporarily tighten lower side oil pipe bolt to 26-61 INCH lbs. (3-7 N.m). Tighten upper side oil pipe bolt to 9-13 ft. lbs. (12-18 N.m). Using several steps, tighten side oil pipe bolts in the sequence shown. (Scheme 12)
11. On all models, fill and bleed cooling system. Fill with 50/50 mix of water and coolant. To bleed system, fill system. Run engine at 2500 RPM for 5 minutes. Run engine at 3000 RPM for 5 minutes. Recheck coolant level and fill as necessary. On Protege, check ignition timing.
