TIMING CHAIN (2RZ--FE)
INSPECTION
1. INSPECT TIMING CHAI NS , T I MI NG G E ARS AND
TI MI NG S P RO CKE TS
(a)
Measure the length of 16 links with the chain fully
stretched.
Maximum chain elongation:
No.1 Timing chain
147.5 mm (5.807 in.)
If the elongation is greater than maximum, replace the chain.
HINT:
Make the same measurements pulling at 3 or more places se-
lected at random.
(b)
Wrap the chain around the timing gear and timing sprock-
et.
(c)
Using vernier calipers, measure the timing gear and tim-
ing sprocket diameter with the chain.
NOTICE:
Vernier calipers must contact the chain rollers for measur-
ing.
Minimum gear diameter:
Camshaft
113.8 mm (4.480 in.)
Crankshaft
59.4 mm (2.339 in.)
If the diameter is less than minimum, replace the chain, gears
and sprocket.
2. INSPECT CHAI N T E NS I O NE R S L I PPER AND
V I BRATI O N DAMP E RS
Measure the chain tensioner slipper and vibration damper
wears.
Maximum wear:
1.0 mm (0.039 in.)
If the wear is greater than maximum, replace the slipper and/or
dampers.
3. INSPECT OIL JET
Check the oil for damage or clogging.
If necessary, replace the oil jet.
4. INSPECT NO.1 CHAI N T E NS I O NE R
If necessary, replace the oil jet (No.2 chain tensioner).
