Installation (Pathfinder & Pickup) Nissan Quest I

1. Ensure cylinder No. 1 is at TDC of compression stroke. (Scheme 5) Install tensioner and return spring if removed. If return spring stud was removed, apply thread lock sealant to threads before installing stud. Insert an Allen wrench into hole in tensioner, turn tensioner fully clockwise, and temporarily tighten lock nut.
2. Install timing belt with arrow on timing belt facing front of engine. Align White lines on timing belt with marks on camshaft sprockets and crankshaft sprocket. White lines ensure correct number of teeth exist between timing marks on sprockets.
3. Loosen tensioner lock nut. Using Allen wrench, rotate tensioner by turning Allen wrench clockwise 70-80 degrees. Temporarily tighten lock nut. Rotate crankshaft clockwise at least 2 revolutions.
4. Return cylinder No. 1 to TDC of compression stroke. Using Push/Pull Gauge (J-38387), apply 22 lbs. (10.0 kg) pressure to timing belt between right camshaft sprocket and tensioner. Hold tensioner in position with Allen wrench, and loosen tensioner lock nut.
5. Place a.0138" (.351 mm) feeler gauge at tensioner pulley and timing belt, and rotate crankshaft until feeler gauge is centered between tensioner pulley and timing belt. see scheme 2 Tighten timing belt tensioner lock nut to specification. See «TORQUE SPECIFICATIONS»(ref-155761-S04272646422003062400000).
6. Rotate crankshaft to remove feeler gauge. Rotate crankshaft clockwise at least 2 revolutions until cylinder No. 1 is at TDC of compression stroke. Measure timing belt deflection halfway between camshaft sprockets. If deflection is not.51-.59" (13-15 mm), repeat steps 4) and 5). To complete installation, reverse removal procedure.
