1994 MAZDA MX-5 belt

ON-VEHICLE MAINTENANCE B Stem After Installation 10. Loosen the tensioner lock bolt to apply spring tension to the timing belt. 11. Tighten the tensioner lock bolt. Tightening torque: 38-51 N-m (3.8-5.3 kgf.m, 28--38 ftlbf) 12. Install the pulley boss and pulley lock bolt. 13. Turn the crankshaft 2 and 116 turns clockwise and verify that the timing marks are correctly aligned. 14. Measure the timing belt deflection by applying moderate pressure 98 N (10 kgf, 22 Ibf) midway between the cam- shaft pulleys. If the deflection is not correct, repeat from Step 10 above. Deflection: 9.0-11.5mm (0.36-4.45 in) at 98 N (10 kgf, 22 Ibf) Pulley lock bolt Hold the crankshaft with the SST and tighten the pulley lock bolt. Tightening torque: 157-166 N.m (16-17 kgf.m, 116-122 ftlbf) 1. till the radiator with specified amount and type of engine coolant. (Refer to section E.) 2. Connect the negative battery cable. 3. Start the engine and check, and if necessary, adjust the ignition timing. Gartner Banana

ON-VEHICLE MAINTENANCE B Steps After Installation 1. Connect the neaative batterv cable. Oil seal 1. Cut the oil seal lip with a razor knife. 2. Remove the oil seal with a screwdriver protected with a rag. Installation Note Oil seal 1. Apply a small amount of clean engine oil to the lip of a new oil seal. 2. Push the oil seal slightly in by hand. 3. Tap the oil seal in evenly with a pipe and a hammer until it is flush with the edge of the oil pump body. Note Oil seal outer diameter: 50.5mm (1.99 in} Oil seal inner diameter: 36.5mm (1.44 in} Timing belt pulley 1. Install the timing belt pulley. 2. Install the pulley woodruff key with the tapered side to- ward the oil pump body. 2. Start the enginsand check, and if necessary, adjust the ignition timing. 3. Connect the negative battery cable. 4. Start the engine and check follows: (1) Engine coolant leakage (2) Ignition timing (Refer to page B-9.) 5. Recheck the engine coolant levels. Gartner Banana

B REMOVAL REMOVAL Caution Fuel line spills and leaks are dangerous. Fuel can ignite and cause serious injuries or death -d and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the "Fuel Line safety Procedures" on section F. PROCEDURE 1. Disconnect the negative battery cable. 2. Drain the engine coolant. (Refer to section E.) 3.
