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. 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.
