TIMING CHAIN AND SPROCKETS Precaution: Timing Chain Replacement CHAIN GUIDES AND TENSIONER ARMS: Replace these parts if grooving in plastic face is more than 1 mm (0.039 inch) deep. If plastic face is severely grooved or melted, the tensioner lube jet may be clogged. The tensioner should be replaced. REMOVAL 1. Disconnect negative cable from battery. 2. Drain cooling system . 3. Remove right and left cylinder head covers. 4. Remove radiator fan shroud. 5. Rotate engine until timing mark on crankshaft damper aligns with TDC mark on timing chain cover (Fig. 132) (# 1 cylinder exhaust stroke) and the camshaft sprocket “V8″ marks are at the 12 o’clock position (Fig. 133). 6. Remove power steering pump. 7. Remove access plugs (2) from left and right cylinder heads for access to chain guide fasteners (Fig. 134). 8. Remove the oil fill housing to gain access to the right side tensioner arm fastener. 9. Remove crankshaft damper and timing chain cover. 10. Collapse and pin primary chain tensioner (Fig. 135). CAUTION: Plate behind left secondary chain tensioner could fall into oil pan . Therefore, cover pan opening. 11. Remove secondary chain tensioners. 12. Remove camshaft position sensor from right cylinder head (Fig. 136). CAUTION: Care should be taken not to damage camshaft target wheel. Do not hold target wheel while loosening or tightening camshaft sprocket. Do not place the target wheel near a magnetic source of any kind. A damaged or magnetized target wheel could cause a vehicle no start condition. CAUTION: Do not forcefully rotate the camshafts or crankshaft independently of each other. Damaging intake valve to piston contact will occur. Ensure negative battery cable is disconnected to guard against accidental starter engagement. 13. Remove left and right camshaft sprocket bolts.


Removal 1. Remove upper radiator crossmember. Disconnect fan assembly connector. Remove fan assembly. Remove drive belts. Using Crankshaft Pulley Holder (8191), hold crankshaft pulley and remove center bolt. Using a 3-jaw puller, remove crankshaft pulley. 2. Remove upper intake manifold. See INTAKE MANIFOLD . Remove electrical and vacuum harness retaining clips from valve cover studs. Remove ignition coils. Remove valve covers. Remove power steering pump and set aside. Remove drive belt tensioner pulley and bracket. Remove timing chain cover. 3. Align crankshaft sprocket timing mark to mark on oil pump housing. Mark on oil pump housing is 60 degrees ATDC of number one cylinder. See Fig. 10

3406E Truck Engine Installation OR Removal Of The Speed/ Timing Sensor

1. Disconnect the speed/timing connector “P9/J9″ (2) . Inspect the connector for the following conditions. * Corrosion * Bent pins * Missing pins * Damaged sockets * Mismating * Broken wires 2. Remove the Speed/timing sensor (1) from the front gear cover. 3. Examine the plastic end of the sensor for signs of wear or contaminants such as metal filings. The plastic end of the speed/timing sensor should have no contaminants and should show no wear (greater than 0.051 mm (0.0020 inch) from the face) . 4. Use a screwdriver to carefully pry the plastic sensor end to the fully extended position (approximately 4.775 mm (0.1880 inch) beyond the metal housing of the sensor). 5. Gently push in on the plastic end of the sensor. The plastic end should be firm. The plastic end should resist movement in the retract direction. If there is no resistance replace the sensor 6. Remove the two bolts (3) and remove the cover (5) from the flywheel housing. This hole is used for engine turning. 7. Put one bolt (3) in the timing bolt location (4) . The timing bolt location is approximately 127 mm to 152 mm (5 inch to 6 inch) above the hole in the flywheel housing for engine turning. I 8. Use 9S-9082 Engine Turning Tool (6) and a 1/2 inch drive ratchet wrench to turn the engine flywheel in the direction of normal engine rotation. The normal engine rotation is in a counterclockwise direction when viewed from the flywheel end. Turn the engine flywheel until the timing bolt engages with the threaded hole in the flywheel. Note: Visually check the location of the tooth on the wheel on which the speed/timing sensor is to be positioned. The end of the sensor must be in alignment with a tooth on the wheel and not in alignment with the valley of the wheel. Note: The No. 1 piston must be at either top center of the compression stroke or at top center of the exhaust stroke. 9. Inspect the speed/timing sensor before installation. Use steps 3 through step 6 to inspect the sensor. 10. If the sensor end is not fully extended, use a screwdriver to carefully pry the plastic sensor end to the fully EXTENDED position approximately 4.775 mm (0.1880 inch) beyond the metal housing of the sensor.

1999 Volkswagen New Beetle GL timing belt replacement manual

REMOVAL & INSTALLATION NOTE: For 2004, manufacturer does not provide a timing belt replacement interval. CAUTION: This application is an interference engine. Do not rotate camshaft or crankshaft when timing belt is removed, or engine damage may occur. NOTE: Engine code AEG is stamped into machined pad on front of cylinder block above crankcase breather, near cylinder head mating surface. See Fig. 1 . For all other 2.0L engines, engine code is stamped on transmission mating flange at the rear of the engine. See Fig. 2 . For all engines, code can also be found on the vehicle data plate and on a sticker on the timing belt cover. Fig. 2: Locating Engine Identification Code (AVH, AZG, BDC & BEV) Courtesy of VOLKSWAGEN UNITED STATES, INC. TIMING BELT Removal (AEG, AVH, AZG, BEV & BDC Engine Codes) 1. Remove right hand insulation tray from engine compartment. Remove engine cover. Rotate serpentine belt tensioner clockwise to relieve belt tension. Remove serpentine belt. See Fig. 3 . Lock in place using Mandrel (T10060) or a drift. Fig. 3: Releasing Serpentine Belt Tensioner Courtesy of VOLKSWAGEN UNITED STATES, INC. 2. Remove serpentine belt tensioner assembly. See Fig. 4 . Turn crankshaft to TDC position. See Fig. 5 . Align TDC marks visible in bellhousing access hole. See Fig. 6 . Remove upper timing belt cover. Ensure camshaft sprocket timing mark aligns with mark on rear cover. See Fig. 5 . 3. Support engine from above or below with floor jack to take engine weight off of mounts. Remove coolant reservoir and set aside. On Golf and Jetta, remove power steering reservoir (hoses attached), and set aside. On New Beetle, pull off EVAP hoses at EVAP canister and throttle valve housing. 4. On all models, remove engine mount from timing belt end of engine. See Fig. 7 . Remove crankshaft pulley from crankshaft sprocket. It is NOT necessary to remove center bolt (center bolt is torque-to-yield type that must be replaced if removed). 5. Remove timing belt covers. Remove engine support from front of engine. See Fig. 4

INSTALLATION SERVICE POINTS >> A << TIMING BELT INSTALLATION CAUTION: If the timing belt is to be re-used, use chalk to mark (on its flat side) an arrow indicating the clockwise direction. CAUTION: After installing the timing belt, try to rotate the camshaft sprocket in the reverse direction. Recheck to be sure that the belt is fully tensioned and that each timing mark is in the proper position. 1. With the timing belt tensioner pulley bolt loosened, use a screwdriver to pry the tensioner pulley as close to the engine mount as possible. Then temporarily tighten tensioner bolt. Fig. 81: Adjusting Timing Belt Tensioner Courtesy of MITSUBISHI MOTOR SALES OF AMERICA. 2. Align each of the camshaft and crankshaft sprocket timing marks. 3. Install the timing belt in the following order, while making sure that the tension side of the belt is not loose. 1. Crankshaft sprocket 2. Water pump sprocket 3. Camshaft sprocket 4. Tensioner pulley >> B << TIMING BELT TENSION ADJUSTMENT 1. Initially loosen the fixing bolt of the tensioner pulley fixed to the engine mount side by 1/4-1/2 turn, and use the force of the tensioner spring to apply tension to the belt. 2. Turn the crankshaft in the proper rotation direction (clockwise) for two rotations, and recheck to be sure that the timing marks on each sprocket are aligned.
