TIMING & BALANCE SHAFT BELTS Removal 1. Disconnect negative battery cable. Position crankshaft with cylinder No. 1 at TDC of compression stroke. See Fig. 1 , Fig. 2 or Fig. 3 . Disconnect battery negative cable. Remove splash shield. Remove cruise control actuator, leaving cable connected. Remove power steering pump, leaving hoses connected. 2. Disconnect alternator wiring. Remove wiring harness from valve cover. Remove alternator and A/C belts (if equipped). Remove valve cover and upper timing belt cover. Remove side engine mount. Remove engine oil dipstick and tube. Remove crankshaft pulley. See Fig. 4 . 3. Support engine. Remove 2 rear bolts from engine center support beam. Lower engine enough to permit removal of lower timing belt cover. Remove rubber seal from belt tension adjuster nut. Remove lower timing belt cover. Inspection With belt or belt covers removed, inspect belts for wear, cracks, or oil soaking. Inspect belt teeth for wear. Replace belt if worn, oil soaked, or cracked. Installation 1. Align White mark on flywheel or drive plate (flexplate) with pointer on block. Ensure camshaft(s) is at TDC for No. 1 cylinder. See Fig. 1 , Fig. 2 or Fig. 3 . Install camshaft timing belt. See Fig. 6 . Align rear timing balance shaft belt pulley by inserting a 6 x 100 mm bolt 2.9″ (74 mm) into alignment access hole. Align groove on front balance shaft pulley with pointer on oil pump body. See Fig. 7 . 2. Adjust timing belt tension by rotating crankshaft counterclockwise until No. 1 piston is at TDC of compression stroke. Loosen, but do not remove, timing belt adjustment bolt. Rotate crankshaft counterclockwise 3 teeth on camshaft pulley to create tension on timing belt. Tighten adjustment bolt to specification. See TORQUE SPECIFICATIONS . 3. Reverse removal procedure to complete installation. Tighten crankshaft pulley bolt to specification. See TORQUE SPECIFICATIONS . Adjust drive belts to proper tension


Removal 1. Disconnect negative battery cable. Remove engine undercover. Place wooden block between jack and oil pan, and raise engine slightly. Remove engine mount assembly near timing belt cover. 2. Remove clamp for power steering return hose near timing belt cover. Remove all drive belts and tensioner pulley bracket. See Fig. 1 . Remove power steering and water pump pulleys. Rotate crankshaft clockwise so that No. 1 cylinder is at TDC of compression stroke. Remove crankshaft pulley. 3. Remove upper timing belt cover and gasket. Remove stub bolt of engine support bracket, and remove center timing belt cover. Remove lower timing belt cover. 4. Ensure camshaft, crankshaft and oil pump sprocket timing marks are aligned. See Fig. 2 or Fig. 3 . Loosen tensioner pulley center bolt. Move tensioner to relieve timing belt tension. Remove timing belt. Remove timing belt auto tensioner. See Fig. 1 . 5. Remove plug from left side of cylinder block. Install a .31″ (8.0 mm) diameter Phillips screwdriver into the hole against balance shaft. See Fig. 4 . Screwdriver must go in at least 2.36″ (60 mm) or more. If screwdriver will only go in about .79-.98″ (20-25 mm) before striking balance shaft, turn sprocket one revolution and align timing mark. Keep screwdriver in place until timing belt is installed. This ensures balance shaft driven by oil pump sprocket remains in correct position. 6. To remove timing belt “B” (balance shaft belt), hold crankshaft sprocket stationary with a spanner wrench. Remove crankshaft sprocket bolt. Using gear puller, remove outer crankshaft sprocket. 7. Remove crankshaft sensing blade (if equipped). See Fig. 5 . Loosen timing belt “B” tensioner bolt. If reusing timing belt “B”, mark direction of belt rotation for reassembly reference. Remove timing belt “B Inspection 1. Inspect timing belts for damaged teeth and cracking. Ensure belts are not contaminated with oil. Check tensioners for free rotation and grease leakage. Replace components if damaged or if grease leakage exists. 2. Check timing belt auto tensioner for leaks. Hold timing belt auto tensioner upright. Measure rod protrusion above edge of housing. See Fig. 6 . Length should be .47″ (12 mm). Apply 22-44 lbs. (10-20 kg) of force to end of rod. If auto tensioner rod moves more than 0.39″ (1 mm), replace the auto tensioner.

2002 Mitsubishi Montero Limited Removing Drive Belt Auto Tensioner/ Aligning Timing Marks

Aligning Timing Marks (2001-02 Montero) Courtesy of MITSUBISHI MOTOR SALES OF AMERICA. Installation (2001-02 Montero) 1. Place auto-tensioner in soft-jawed vise to SLOWLY compress the push rod. If there is a plug at the base of the auto-tensioner body, place flat washer around plug so it will not contact vise jaw. 2. Slowly compress auto-tensioner push rod until holes in push rod and auto-tensioner housing are aligned. Insert a locking pin into the alignment holes. Install auto-tensioner on engine. 3. Ensure all timing marks are still aligned. See Fig. 11 . Install timing belt on crankshaft sprocket, idler pulley, left bank camshaft sprocket, water pump pulley, right bank camshaft sprocket, and tensioner CAUTION: Never compress the auto-tensioner too fast, or the push rod will be damaged. WARNING: Right bank camshaft can easily turn from applied spring pressure. Be careful not to pinch fingers when installing timing belt. 2002 Mitsubishi Montero Limited MITSUBISHI 3.5L V6 – SOHC many waters gallery pulley. Take all slack out of timing belt. 4. Loosen the tensioner pulley center bolt. Using Tensioner Pulley Wrench (MD998767), rotate tensioner pulley against timing belt. Temporarily tighten tensioner pulley center bolt. Using Crankshaft Pulley Spacer (MD998769), turn crankshaft 1/4 turn counterclockwise. Turn crankshaft 1/4 turn clockwise. Ensure all timing belt marks are still aligned. 5. Loosen tensioner pulley center bolt. Position tensioner pin holes at bottom of tensioner. Install Tensioner Pulley Wrench (MD998767) on tensioner pulley. See Fig. 12 . Using torque wrench, apply 39 INCH lbs. (4.4 N.m) of torque (counterclockwise direction) to tensioner pulley. Tighten tensioner center bolt to specification while holding tensioner pulley stationary. See TORQUE SPECIFICATIONS . 6. Remove locking pin from auto-tensioner. Turn crankshaft 2 revolutions clockwise and align all timing marks. DO NOT rotate counterclockwise. 7. Wait for at least 5 minutes, then check auto-tensioner push rod protrusion. To check push rod protrusion, measure clearance between body of auto-tensioner and bottom of tensioner pulley bracket arm. Clearance should be 0.15-0.20″ (3.8-5.0 mm). If protrusion is not correct, repeat timing belt tensioning procedure. Ensure all timing marks are aligned. 8. Install timing belt covers. See Fig. 10 . Install crankshaft pulley. Tighten crankshaft pulley bolt to specification. See TORQUE SPECIFICATIONS . Install accessory mount assembly on front of engine. See Fig. 13 . See TORQUE SPECIFICATIONS . To install remaining components, reverse removal procedures. See Fig. 7 and Fig. 8 . Adjust drive belts to proper tension. 9. When filling cooling system, use 50/50 mix of coolant and water. Open bleed screw on top of thermostat housing. Slowly fill cooling system until coolant flows out of bleed hole. Install bleed screw. Start engine and run to normal operating temperature. Race engine to 3000 RPM several times. Stop engine. After engine cools, refill radiator and coolant reservoir tank.
