caos.
Reinstall the main caps and bearings on the engine
in proper order,
lf you can feel ridge of metal or hard carbon around
the top of each cylinder, remove it with a ridge
reamer. Follow the reamer manufacturer's instruc-
I|ons.
CAUTION; lf the ridge is not removed, it may dam-

13.Reinstall the connecting rod bearings and caps after
removing each piston/connecting rod assembly.
Mark each piston/connecting rod assembly with its
cylinder number to avoid mixup on reassembly.
NOTE: The existing number on the connecting rod
does not indicate its position in the engine, it indi-
cates the rod bore size.

NOTE:
. Use liquid gasket, part No. 08718 - 0001 or08718-0003.
. Check that the mating surfaces are clean and drybefore apptying liquid gasket.
. Apply liquid gasket evenly, being careful to coverall the mating surface.. To prevent oil leakage, apply liquid gasket to theinner threads of the bolt holes.. Do not install the parts if five minutes or morehave elapsed since applying the liquid gasket.
Instead reapply liquid gasket after removing theold residue.
. After assembly, wait at least 30 minutes beforefilling the engine with oil.

OilJet (B1642 engine)
Inspection
1.Remove the oil jet (see page 8-3) and inspect it asfollows.
Make sure that a 1.1 mm (0.04 in) diameter drillwill go through the nozzte hole (j.2 mm (0.05 in)diameter).
Insert the other end of the same 1.1 mm (0.04 in)drill into rhe oil intake (i.2 mm (0.05 in) diame_ter).
Make sure the check ball moves smoothly andhas a stroke of approximately 4.0 mm (0.16 in).Check the oil jet operation with an air nozzle. ltshould take at least 200 kPa (2.0 kgf/cm,, 28 psi)to unseat the check ball.
NOTE: Replace the oil jet assembly if the nozzlers damaged or bent.

Overhaul
NOTE:
. Use new O rings when reassembllng.
. Apply oil to O-rings before installation.
. Use liquid gasket, Part No. 08718 - 0001 or 08718 - 0003
. The rotors must be installed to the same direction in order'
o After reassembly, check that the rolors move without binding'

17. Reassemble the oil pump, applying thread lock tothe pump housing screws.
18. Check that the oil pump turns freely.
19. Apply a light coat of oilto the seal lip.
20. Install the two dowel pins and new O-ring on the oilpump.
21. Apply liquid gasket to the cylinder block mating sur_face of the oil pump.
NOTE:
. Use liquid gasket, Part No.08718 - oOOj or 08718- 0003.. Check that the mating surfaces are clean and drybefore applying liquid gaskel. Apply liquid gasket evenly, in a narrow bead cen-tered on the mating surface.o To prevent leakage of oil, apply liquid gasket tothe inner threads of the bolt holes.. Do not install the parts if five mtnures or morehave elapsed since applying liquid gasket.Instead. reapply liquid gasket after removing theold residue.
. After assembly, wait at least 30 minutes beforefilling the engine with oil.
