(9)Mark support assembly to engine bracket if assembly is to be used again. Separate engine mount insulator from engine mount bracket (Fig. 10). Raise engine slightly.

(10)Remove engine mount bracket (Fig. 10).

(2)Inspect both sides of the timing belt drive & back. Replace belt if any of the following conditions exist.

²Hardening of back rubber back side is glossy without resilience and leaves no indent when pressed with fingernail.

²Cracks on rubber back.

²Cracks or peeling of canvas.

²Cracks on rib root.

²Cracks on belt sides.

²Missing teeth.

²Abnormal wear of belt sides. The sides are normal if they are sharp as if cut by a knife (Fig. 12).

(3)If none of the above conditions are seen on the belt, the belt cover can be reinstalled.

(3) Turn timing belt tensioner counter-clockwise full travel in adjustment slot and tighten bolt to temporarily hold this position (Fig. 17).

INSTALLATIONÐTIMING BELT

(1)Install timing belt on crankshaft sprocket first and while keeping belt tight on tension side (Fig. 14) install belt on the front (radiator side) camshaft sprocket.

(2)Then, install on the water pump pulley and on the rear camshaft sprocket and finally on the timing belt tensioner.

(3)Apply rotating force to the front camshaft sprocket in opposite direction to tension the belt tension side, check that all timing marks are lined up (Fig. 14).

(4)Install crankshaft sprocket flange (Fig. 12).

(5)Loosen tensioner bolt and allow spring to tension timing belt.

(6)Turn crankshaft two full turns in clockwise direction. Turn smoothly and in clockwise direction ONLY.

(7)Again line up the timing marks on the sprockets and tighten the timing belt tensioner locking bolt to 25 Nzm (250 in. lbs.) torque.

(8)Reassembly belt covers, engine bracket, insulator, crankshaft pulleys, accessories and accessory drive belts in reverse order.
