Oil Pressure
Use this procedure to tighten the filter if eight num-
bers (1 to 8) are printed on the surface of the filter.
1) Make a mark on the oil filter base under the num-
ber that shows at the bottom of the filter when
the rubber seal is seated.
2l Tighten the filter by turning it clockwise seven
numbers from the marked point. For example, if a
mark is made under the number 2 when the rub
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point'
7/8 turn
Number when rubDer
seal is seated
Number after tightening.
CAUTION: Using any procedure other than those
shown could rosult in serious engins damage due
to oil leakage
5. After installation. fill the engine with oil up to the spec-
ified level, run the engine for more than three minutes,
then check for oil leakage

Testing
lf the oil pressure warning Iight stays on with the engine
running, check the engine oil level. It the oil level is cor-
rect:
1. Connect a tachometer'
2. Remove the engine oil pressure switch, and install an
oal pressure gauge.

ADAPTER(1/8\28. BSPTI
{CommerciallY availablei
Start the engine. Shut it off immediately if the gauge
registers no oil pr€ssure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (tan
comes on at least tlivice). The pressure should be;
Engine Oil Temperature: 176"F (80"C1
Engine Oil Pressulo:
At ldle: 69 kPa (0.7 kgf/Gm'. 10 Psi)
minimum
At 3.000 rpm: 3/Ut kPa (3.5 kgt/cm', 50 psi)
minimum
. lf the oil Dressure is within specifications, replace
the oil pressure switch and recheck.
. lf the oil pressure is NOT within specifications,
inspect the oil pump (see page 8-10).

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'
