REMOVAL SERVICE POINT



<<A>> OIL PAN REMOVAL



1.Remove the oil pan mounting bolts.
2.Knock the special tool Oil pan remover (MD998727) between the oil pan and cylinder block as shown in the illustration.
3.Tapping the side of the special tool, slide the tool along the oil pan/cylinder block seal and thus remove the oil pan.

INSTALLATION SERVICE POINTS



>>A<< OIL PUMP CASE INSTALLATION



1.Completely remove existing form-in-place gasket from the cylinder block (oil pump case mounting surface) and oil pump case.
2.Apply a 3 ± 1 mm bead of form-in-place gasket to the oil pump case at the positions shown in the illustration.
Specified sealant:
    Three bond 1207F or equivalent

3.
caution The mounting bolts are different in length. Take care not to use wrong bolts in wrong places.
Install the oil pump case to the cylinder head, and tighten mounting bolts to a specified torque of 14 ± 1 N·m.

>>B<< FRONT OIL SEAL INSTALLATION



1.Place the special tool Crankshaft front oil seal guide (MB991962) on the crankshaft’s front end and apply engine oil to the its outer circumference.

2.Apply engine oil to the oil seal lip, then push the oil seal along the guide by hand until it touches the front case. Tap the oil seal into place using the special tool Camshaft oil seal installer (MD998306).

>>C<< OIL PAN INSTALLATION



1.Completely remove existing form-in-place gasket from the cylinder block (oil pan mounting surface) and oil pan.
2.Apply a 4 ± 1mm bead of form-in-place gasket to the oil pan at the positions shown in the illustration.
Specified sealant:
    Three bond 1207F or equivalent
3.Install the oil pan to the cylinder block and tighten the tightening bolt to the specified torque of 7.0 ± 1.0 N·m.

>>D<< DRAIN PLUG GASKET INSTALLATION



caution Installing the gasket with the wrong side facing the oil pan will result in oil leakage.
Replace the drain plug gasket with a new one. Install it with the side indicated in the illustration toward the oil pan.

>>E<< OIL PRESSURE SWITCH INSTALLATION



caution
  • The threaded part tip of the switch must be clear of the sealant.
  • Be careful not to overtighten the switch.
1.Completely remove existing sealant from the oil pressure switch and the switch mounting hole on the oil pump case.
2.Apply specified sealant to the threaded part of the oil pressure switch as shown.
Specified sealant:
    Three bond 1207F or equivalent
3.Install the oil pressure switch to the oil pump case by tightening to a specified torque of 10 ± 2 N·m.

>>F<< OIL FILTER INSTALLATION



1.Clean the filter mounting surface on the front case.
2.Apply engine oil to the O-ring of the oil filter.

3.
caution If the filter is tightened by hand only, it will be insufficiently torqued, resulting in oil leaks.
Screw the oil filter in and tighten the oil filter to the specified torque using a commercially available filter wrench from where the O-ring has come into contact with the oil filter mounting surface.
Specified torque:
    MD348631, MD365876 16 ± 4 N·m (approx. 3/4 of a turn)
    MD360935 14 ± 2 N·m (approx. 1 turn)
