- Slide bracket (HI)
- Foot x 2 (standard) (MB991932)
- Foot x 2 (short) (MB991933)
- Joint x 2 (90) (MB991930)
(2)
Set the foot of the special tools (MB991930, MB991932 and MB991933) as shown in the figure.
|
|
| note |
Slide the slide bracket (HI) to adjust the engine hanger balance.
|
|
(3)
Install special tool engine hanger plate (MB991956) to the cylinder head, and set special tool hanger (MB991527) and the chains of special tool engine hanger balancer (MB991454) to the engine assembly to hold the engine and transmission assembly.
|
|
2.<When special tool engine hanger (MB991895) is used>
(1)
|
|
| caution |
Place a rag between special tool engine hanger (MB991895) and the windshield to prevent the special tool (MB991895) from interfering with the windshield.
|
|
Set the foot of special tool engine hanger (MB991895) as shown in the figure.
|
|
| note |
Slide the foot to adjust the engine hanger balance.
|
|
(2)
Install special tool engine hanger plate (MB991956) to the cylinder head, and set special tool hanger (MB991527) and the chains of special tool engine hanger balancer (MB991454) to the engine assembly to hold the engine and transmission assembly.
|
|
1.
| caution |
If the adhesive strength of sealant on the timing chain case assembly is so strong that the boss may be damaged by peeling off, do not peel it off forcibly.
|
After removing the timing chain case assembly mounting bolts, slightly pry the boss of the timing chain case assembly shown in the figure using a flat-tipped screwdriver, and remove the timing chain case assembly from the cylinder head and cylinder block.
|
|
2.If the sealant cannot be peeled off easily, insert a wooden hammer shank into the timing chain case assembly inside as shown in the figure, pry slightly, and remove the timing chain case assembly from the cylinder head and cylinder block.
|
|
|
1.Temporarily install the crankshaft pulley to the crankshaft.
|
|
2.
| caution |
Turn the crankshaft clockwise.
|
Turn the crankshaft clockwise to align the sprocket timing marks as shown in the figure and set the cylinder No. 1 to the top dead centre of compression.
| note |
At this time, it is not necessary that the link plate (orange) of the valve timing chain always aligns with each sprocket timing mark.
|
3.Remove the crankshaft pulley installed temporarily.
|
|
4.Using a precision flat-tipped screwdriver, release the ratchet of timing chain tensioner.
5.Compress the plunger of timing chain tensioner and insert hard wire (such as the piano wire) or the L-shaped hexagon wrench (1.5 mm) to fix the plunger of the timing chain tensioner.
6.Remove the timing chain tensioner.
|
|
1.Set the timing marks of the camshaft sprockets and the crankshaft sprocket as shown in the figure.
|
|
2.Align each sprocket timing chain mating mark with the link plate (orange) of valve timing chain to avoid slack of the valve timing chain tension side, and install the valve timing chain to the sprockets.
|
|
1.Check that the sprocket timing chain mating marks align with the link plates (orange) of the valve timing chain, and install the timing chain tensioner to the cylinder block.
|
|
2.Remove the hard wire or L-shaped hexagon wrench fixing the plunger of the timing chain tensioner to apply tension to the valve timing chain.
|
|
|
1.Apply a small amount of engine oil to the entire inner diameter of the crankshaft front oil seal lip.
|
|
2.
| caution |
When installing the crankshaft front oil seal, be careful to avoid damage to the crankshaft front oil seal.
|
Using special tool bush remover and installer base (MB991448), press in the crankshaft front oil seal up to the chamfered surface of timing chain case.
|
|
|
1.
| caution |
- Be sure to remove the sealant inside the mounting holes and the O-ring grooves.
- After degreasing with white gasoline or the like, check that there is no oil on the surface where the sealant is applied.
- After degreasing with white gasoline or the like, never touch the degreased area with fingers.
|
Remove sealant from the timing chain case assembly and the timing chain case assembly mounting surface of the cylinder block and the cylinder head, and degrease the surface where the sealant is applied by white gasoline or the like.
|
|
2.Apply a bead of the sealant to the timing chain case assembly mounting surface. The bead diameter should be 2.5 ± 0.5 mm. Overlap the part "A" with the diameter of 4.5 ± 0.5 mm or 2.5 ± 0.5 mm as shown in the figure, and apply the sealant.
Specified sealant: MITSUBISHI GENUINE PART 1000A923, Loctite 5900, 5970, 5971 or equivalent
3.
| caution |
- If the sealant contacts any other part during installation of the timing chain case assembly, apply sealant again before installing the timing chain case assembly.
- Do not apply oil or water to the sealant-applied area or start up the engine within 2 hours after the installation of the timing chain case assembly.
|
Install the timing chain case assembly to the cylinder block and cylinder head so that the sealant does not contact other parts.
| note |
Install the timing chain case assembly within 3 minutes after the application of sealant.
|
|
|
4.Insert the bolts to the timing chain case assembly as shown, and tighten them to the specified torque.
