Engine unit 2AD-FHV Inspection

INSPECT CHAIN SUB-ASSEMBLY Using spring scale, pull the chain with a force of 147 N (15 kgf, 33 lbf) as shown in the illustration. Using vernier calipers, measure the length of 16 links. Maximum chain elongation: 144.3 mm (5.681 in.) If the elongation is greater than the maximum, replace the chain. NOTICE: Perform the same measurement by pulling at random in 3 or more places to obtain an average.
