I changed a crankshaft sensor, didn`t understand it to be going to be so lot trouble for such a tiny part. Currently that I`ve obtained the thing readjusted I`ll need to reset the time belt. The belt was readjusted at 70,000 miles. Ns didn`t adjusted it myself. I`ve never readjusted a timing belt prior to thought I`ld adjust the sensor to conserve some money. Ns can`t uncover the timing Marks onthe crank pulley only a small metal peg difficult up ~ above the crank and also nothing on the block or around the crank. Please aid me. I certain would evaluate it. Ns Can`t donate anything right yet I will when I get back to working. Thanks & God Bless You. Richard.

Invest in a camshaft locking tool ..and make sure #1 piston is at TDC (top dead centre) by removing the spark plug and manually checkingRemovalCAUTION:To prevent engine damage, do NOT revolve crankshaft counterclockwise (as perceived from time belt end of engine).Disconnect an adverse battery cable. Eliminate drive belts and also drive pulleys from crankshaft and also water pump. Remove timing belt covers. To align timing marks, revolve engine clockwise for this reason No. 1 cylinder is at TDC of compression stroke. For sure camshaft sprocket timing marks align v upper surface ar of rocker cover. Dowel pen of camshaft sprocket should be pointing upward. Check out Fig. 1 . Remove timing belt auto tensioner. If reusing time belt, location mark on timing belt to show direction the belt rotation. Eliminate timing belt. Remove camshaft sprockets. Remove plug at left side of block, and also insert a screwdriver to hold left counterbalance column in position. Screwdriver will have to be put at the very least 2.36" (60 mm). Eliminate oil pump sprocket nut and also sprocket. Check out Fig. 2 . Loosen right counterbalance column sprocket mounting bolt. Eliminate tensioner "B" and also timing belt "B". Watch Fig. 2 . Eliminate crankshaft sprocket "B" from crankshaft. Fig. 1: Identifying time Belt Alignment MarksCourtesy that HYUNDAI motor CO.Fig. 2: Exploded see Of time Belt ComponentsCourtesy of HYUNDAI engine CO.InspectionTips Click a attach to view tipTech1Tip: timing BELT TEETHCheck belt this for cracks, damage and also oil contamination. Inspect sprockets for damage. Inspect tensioner pulley and also idler pulley for grease leakage and roughness in rotation. Check sprockets and also pulleys because that wear, crack or damage. Replace components if necessary. Measure up protrusion of auto tensioner rod. Auto tensioner rod should prolong .57" (14.5 mm) from finish of housing. View Fig. 3 . Change auto tensioner pole if no within specification. Ar tensioner in a soft-jawed vise, and also test resistance of rod. If rod can be easily pushed in with light vise pressure, replace auto tensioner. Fig. 3: measuring Auto Tensioner ProtrusionCourtesy the HYUNDAI engine CO.InstallationTips Click a link to view tipTech1Tip: time belt alignment download crankshaft sprocket "B" ~ above crankshaft. Certain flange is effectively positioned. Lightly oil external surface of spacer, and then install spacer to best counterbalance shaft, through rounded leaf of spacer inward. Install appropriate counterbalance tower sprocket. Tighten flange bolt strict by hand. Align timing marks on every sprocket and also on front case. Check out Fig. 4 . As soon as installing timing belt "B", ensure there is no slack in tension side. Install tensioner "B" in facility of wheel on left next of mounting bolt, and also in sheave flange towards front the engine. View Fig. 5 . Align timing mark of best counterbalance pillar sprocket v timing mark on front case. Come tighten time belt "B", elevator tensioner "B" so tension side is traction tight. Tighten bolt to secure tensioner "B". Perform NOT turn shaft, or belt will certainly be over-tightened. Ensure timing marks room aligned. Ensure facility of span on stress side of time belt "B" can be depressed by hand. Certain belt deflection is .20-.30" (5-7 mm). Download crankshaft sprocket flange and sprocket. Certain flange is placed in suitable direction, v chamfered side toward block. Install special washer and also sprocket bolt to crankshaft. Tighten sprocket bolt come specification. Check out TORQUE SPECIFICATIONS . Insert lengthy screwdriver v plug feet in left side of cylinder block to organize counterbalance pillar in position. Install oil pump sprocket, and tighten seed to specification. Watch TORQUE SPECIFICATIONS . Download camshaft sprockets, and tighten bolts. If auto tensioner rod is completely extended, place it in soft-jawed vise, and compress rod until hole in rod currently up through hole in auto tensioner housing. Insert stiff cable to hold rod in this position. Download auto tensioner, leaving cable in place. CAUTION:If time marks ~ above camshaft sprockets execute not heat up properly, execute NOT revolve sprocket an ext than 2 this in either direction, or valve and also piston will certainly touch. If necessary, remove and reposition camshaft sprocket.Install crankshaft sensor. Collection timing point out of camshaft sprockets v notches on top side of rocker cover and dowel pins right up. Align crankshaft sprocket time marks. Align oil pump sprocket timing marks. Install time belt in order approximately crankshaft sprocket, oil pump sprocket, idler pulley, exhaust camshaft sprocket, input camshaft sprocket and tensioner pulley. Tenderness raise tensioner wheel so belt will not sag, and then temporarily tighten facility bolt. Certain timing note of every sprocket is tho aligned. Remove wire indigenous auto tensioner. Rotate crankshaft 2 finish turns clockwise. Leaving in this place for around 5 minutes. Measure up auto tensioner protrusion "A" (distance between tensioner arm and auto tensioner body). Ensure auto tensioner protrusion is .22-.35" (6-9 mm). Watch Fig. 3 .
