Installation
1. Install� No.� 2� idler� pulley� (if� removed).� Install� and� tighten� bolt� to� specification.� See TORQUE� SPECIFICATIONS.� Ensure� idler� pulley� is� clean� and� rotates� smoothly.
2. Install� No.� 1� idler� pulley� and� tension� spring� (if� removed).� Pry� No.� 1� idler� pulley� away� from� timing� belt� area� as� far� as� possible.� Temporarily� tighten� No.� 1� idler� pulley� bolt.� Ensure� idler� pulley� is� clean� and� rotates
smoothly.
3. Using� crankshaft� pulley� bolt, � rotate� crankshaft� so� timing� mark� on� crankshaft� sprocket� aligns� with� timing� mark� on� oil� pump� housing.� See Fig.� 4.� This� will� position� keyway� in� crankshaft� sprocket� at� 12� o'clock
position.
CAUTION: If� reusing� timing� belt, � ensure� reference� marks� on� timing� belt� align� with� reference� marks� placed� on� crankshaft� and� camshaft� sprockets.� Ensure� timing
belt� is� installed� in� original� direction� of� rotation.
4. Ensure� all� sprockets� and� idler� pulleys� are� clean.� Install� timing� belt� on� crankshaft� sprocket, � oil� pump� sprocket, � No.� 1� idler� pulley, � and� then� No.� 2� idler� pulley� in� sequence.
5. Install� timing� belt� guide� with� cupped� side� away� from� crankshaft� sprocket� and� flat� side� toward� timing� belt.� Install� No.� 1� timing� belt� cover� and� new� gasket.
6. Align� crankshaft� pulley� key� groove� with� key� in� crankshaft.� Install� crankshaft� pulley.� Install� and� tighten� crankshaft� pulley� bolt� to� specification.
7. Rotate� crankshaft� clockwise� so� cylinder� No.� 1� is� at� TDC� on� compression� stroke.� Ensure� timing� mark� on� crankshaft� pulley� aligns� with� "0"� mark� on� No.� 1� timing� belt� cover.� If� reusing� timing� belt, � ensure� reference
mark� on� timing� belt� aligns� with� upper� edge� of� No.� 1� timing� belt� cover.
8. Rotate� camshaft, � and� align� hole� in� camshaft� sprocket� with� alignment� mark� on� camshaft� bearing� cap.� See Fig.� 2.� Install� timing� belt� on� camshaft� sprocket.� If� reusing� timing� belt, � ensure� reference� mark� on� timing� belt
aligns� with� the� reference� mark� on� camshaft� sprocket.� Ensure� tension� exists� on� timing� belt� between� the� crankshaft� and� camshaft� sprockets.
CAUTION: DO� NOT� rotate� crankshaft� counterclockwise, � as� viewed� from� timing� belt� end� of� engine.
9. Loosen� No.� 1� idler� pulley� bolt� 1/2� turn.� Rotate� crankshaft� pulley� 2� full� revolutions� clockwise� from� TDC� to� TDC.
10. Ensure� timing� mark� on� crankshaft� pulley� aligns� with� "0"� mark� on� No.� 1� timing� belt� cover, � and� hole� in� camshaft� sprocket� aligns� with� alignment� mark� on� camshaft� bearing� cap.� See Fig.� 2.� If� timing� marks� are� not
aligned, � remove� timing� belt� and� reinstall.
11. Rotate� crankshaft� clockwise� 1� and� 7/8� revolutions� and� align� crankshaft� pulley� "0"� mark� with� 45 degree� Before� Top� Dead� Center� (BTDC)� mark� on� No.� 1� timing� belt� cover.� See Fig.� 5.
12. Tighten� No.� 1� idler� pulley� bolt� to� specification.� See TORQUE� SPECIFICATIONS.� Install� No.� 2� timing� belt� cover� and� gaskets.� Install� and� tighten� spark� plugs� to� specification.
13. To� install� remaining� components, � reverse� removal� procedure.� Install� all� bolts/nuts� on� right� (timing� belt� side)� engine� mount� before� tightening� to� specification.
14. On� Camry, � when� installing� control� rod� and� bracket� on� strut� tower� and� right� (timing� belt� side� engine� mount, � tighten� bolts� to� specification� in� sequence.� See Fig.� 6.� On� MR2, � tighten� engine� mount� bolts� in� correct
locations.� See Fig.� 7.� Adjust� drive� belts� to� proper� tension.
