Install the timing chain cover.
Using a gasket scraper, remove all the old packing material from the gasket surfaces.
The sealant locations on the chain cover and the counter parts (cam carrier, cylinder head, cylinder block, and lower crankcase) must be free of harmful foreign materials, oil, dust and moisture. Spraying cleaner on the surface and wiping with a clean duster.
Before assembling the timing chain cover, liquid sealant should be applied on the gap between cam carrier, cylinder head and cylinder block.
Bead width: 3.0 ~ 5.0 mm (0.11 ~ 0.20 in.)
Sealant: Threebond 1217H or equivalent
After applying liquid sealant on the timing chain cover, assemble the cover within 5 minutes after sealant was applied. Continuous bead of sealant should be applied to prevent any path from oil leakage.
Bead width
Whole section: 2.5 ~ 3.5 mm (0.10 ~ 0.14 in.)
Section A: 4.5 ~ 5.5 mm (0.18 ~ 0.22 in.)
Section B: 8.0 ~ 9.0 mm (0.32 ~ 0.35 in.)
Sealant: Threebond 1217H or equivalent
Install the timing chain cover. The dowel pins on the cylinder block and holes on the timing chain cover should be used as a reference in order to assemble the timing chain cover in exact position.
Tightening torque
Bolts (A, B):
18.6 ~ 23.5 N.m (1.9 ~ 2.4 kgf.m, 13.7 ~ 17.4 lb-ft)
Bolt (C):
19.6 ~ 23.5 N.m (2.0 ~ 2.4 kgf.m, 14.5 ~ 17.4 lb-ft)
Bolts (D,E):
39.2 ~ 49.0 N.m (4.0 ~ 5.0 kgf.m, 28.9 ~ 36.2 lb-ft)
Bolt (F):
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Do not reuse the seal bolts (C,F).
The engine running or pressure test should not be performed within 30 minutes after the timing chain cover was assembled.
