Removal and Installation: Installation
WARNING: This page is about a different variant/trim than selected.
NOTE:
- There may be two color variations of the link marks (link colors) on the timing chain.
- There are 26 links between the gold/yellow mating marks on the timing chain; and 64 links between the camshaft sprocket gold/yellow link and the crankshaft sprocket orange/blue link, on the timing chain side without the tensioner.
- Make sure the crankshaft key points straight up.
- Install the balancer unit and tighten the bolts in the numerical order as shown:CAUTION:
- When reusing a bolt, check its outer diameter before installation. Refer to
"BALANCER UNIT BOLT OUTER DIAMETER ".
Tool number : KV10112100 (BT-8653-A)
CAUTION:- Check tightening angle with an angle wrench or a protractor. Do not make judgment by visual check alone.
- Apply new engine oil to threads and seating surfaces of bolts.
Balancer unit bolts
Step 1 : 42 N.m (4.3 kg-m, 31 ft-lb)
Step 2 : 90° - 95° degrees rotation (Target: 90° degrees)
Step 3 (Loosen in reverse order or tightening) : 0 N.m (0 kg-m, 0 ft-lb)
Step 4 : 45.2 - 51.0 N.m (4.6 - 5.2 kg-m, 34 - 37 ft-lb)
Step 5 : 90° - 95° degrees rotation (Target: 90° degrees)
- When reusing a bolt, check its outer diameter before installation. Refer to
"BALANCER UNIT BOLT OUTER DIAMETER ".
- Install the crankshaft sprocket and timing chain for the balancer unit.
- Make sure that the crankshaft sprocket is positioned with mating marks on the block and sprocket meeting at the top.
- Install it by lining up mating marks on each sprocket and timing chain.
- Install timing chain tensioner for balancer unit.NOTE: Chain guide and tensioner move freely with the staking pin as the axle. Therefore, bolt hole position of the three points could be changed during removal. If points change, temporarily tighten the two bolts on the chain guide and move the tensioner to match the bolt holes.
- Be careful not to let mating marks of each sprocket and timing chain slip.
- After installation, make sure the mating marks have not slipped, then remove stopper pin and release tensioner.
- Install timing chain and related parts.
- Install by lining up mating marks on each sprocket and timing chain as shown.
NOTE: Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for that of each sprocket for alignment.CAUTION: For the above reason, after the mating marks are aligned, keep them aligned by holding them with a hand.- Before and after installing chain tensioner, check again to make sure that mating marks have not slipped.
- After installing chain tensioner, remove stopper pin, and make sure the tensioner moves freely.
- To avoid skipped teeth, do not move crankshaft and camshaft until front cover is installed.
- Install new front oil seal to front cover, using suitable tool
- Install new oil seal in until it is flush with front end surface of front cover.
- Install front cover with the following procedure:
- Install O-rings to cylinder head and cylinder block.
- Apply Genuine Silicone RTV Sealant or equivalent, to positions specified in the figure. Refer to
"RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS
".
C (Sealant dimension) : 3.9 mm (0.154 in) dia
- Make sure the mating marks on the timing chain and each sprocket are still aligned. Then install the front cover.
- Tighten front cover bolts in the numerical order as shown.
- After all bolts are tightened, retighten them to the specified torque.
Front cover bolt torque
Bolts A : 49 N.m (5.0 kg-m, 36 ft-lb)
Bolts B : 12.7 N.m (1.3 kg-m, 9 ft-lb)
Bolts C : 12.7 N.m (1.3 kg-m, 9 ft-lb)
Bolts D : 49 N.m (5.0 kg-m, 36 ft-lb)
E Dowel pins
CAUTION: Wipe off any excess sealant leaking at the surface for installing the oil pan.
- Install the chain guide between the camshaft sprockets.
- Install IVT cover with the following procedure:
- Install IVT solenoid valves to IVT cover.
- Install new oil rings to the intake camshaft sprocket insertion points on IVT control cover backside.
- Install new O-ring to front cover.
- Apply Silicone RTV Sealant to the IVT cover as shown.
- Apply Genuine Silicone RTV Sealant or equivalent, to positions specified in the figure. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".
- Tighten the IVT cover bolts in the numerical order as shown.
- Insert crankshaft pulley by aligning with crankshaft key.
- Tap its center with a plastic hammer to insert.
- Do not tap the belt hook.
- Tighten crankshaft pulley bolts.
- Secure crankshaft pulley with a pulley holder to tighten the bolt.
- Perform angle tightening using Tool with the following procedure:
Tool number : KV10112100 (BT-8653-A)
- Apply new engine oil to threads and seat surfaces of bolts.
- Tighten to initial specifications:
Crankshaft pulley bolt initial tightening : 37.3 - 47.1 N.m (3.8 - 4.8 kg-m, 28 - 34 ft-lb)
- Apply a paint mark on the front cover, mating with any one of six easy to recognize stamp marks on bolt flange.
- Turn crankshaft pulley bolt another 60° to 66° degrees [Target: 60° degrees].
- Check vertical mounting angle with movement of one stamp mark.
- Installation of the remaining components is in reverse order of removal.
