SERVICING FRONT OIL

SEALS−REPLACEMENT

(1)With timing belt removed, remove crankshaft sprocket bolt.

(2)Remove crankshaft sprocket using Special Tool C-4685, Insert and 5.9 inch long screw (Fig.7).

(3)Install crankshaft sprocket using plate L-4524, Thrust Bearing/washer and 5.9 inch long screw (Fig. 7).

(4) Hold engine sprocket with Special Tool C-4687 (with adaptor Tool C-4687-1) while removing/installing screw (Fig. 8). The 2.5L Engine camshaft/intermediate shaft sprockets have an off-set hub and are identified with a six-hole pattern.

and Camshaft seals using Special Tool C-4680. Install seals until flush (Fig. 10).

Fig. 11 Crankshaft and Intermediate Shaft Timing

(1)Remove all spark plugs. Turn crankshaft and intermediate shaft until markings on sprockets are in line, see arrows (Fig. 11).

(2)Turn camshaft until arrows on hub are inline with No. 1 camshaft cap to cylinder headline. Small hole (arrow Fig. 12) must be in vertical center line.

(3)Install timing belt.

Fig. 13 Adjusting Drive Belt Tension

(4) Rotate crankshaft two full revolutions and recheck timing.

CAUTION: Do not allow oil or solvents to contact the timing belt as they can deteriorate the rubber and cause tooth skipping.

(5)Rotate crankshaft till number 1 cylinder is at the TDC position.

(6)Put belt tension Special Tool C-4703 horizontally on large hex of timing belt tensioner pulley and loosen tensioner lock nut.

(7)Reset belt tension Special Tool C-4703 index if necessary to have axis within 15° of horizontal. (Fig. 13)

(8)Turn engine clockwise from TDC two crank revolutions to TDC. Do not reverse rotate crankshaft or attempt to rotate engine using cam or accessory shaft attaching screw.

(9)Hold weighted wrench in position while tightening bolt on tensioner to 61 Nzm (45 ft. lbs.) torque.

(10)Lower engine onto engine mount install mounting bolts and tighten to specifications refer to (Fig. 3).

(11)Remove jack from under engine.

(12)Position both halves of timing belt cover together (Fig. 4).

(13)Install fasteners holding cover to cylinder head and block. Tighten fasteners to 4 Nzm (40 in. lbs.) torque.

(14)Valve Timing Check; (timing belt cover installed). With number one cylinder at TDC, small hole in sprocket must be centered in timing belt cover hole (Fig. 12). If hole is not aligned correctly perform procedure again.

(15)Install spark plugs.
