21. Fuel Injection Pipe with Clip
1) Temporarily tighten the injection pipe sleeve nut.
2) Set the clip in the illustrated position.
Note:
Make absolutely sure that the clip is correctly
positioned.
An improperly positioned clip will result in injection
pipe breakage and fuel pulsing noise.
3) Tighten the injection pipe sleeve nut to the specified
torque.

LUBRICATION SYSTEM
LUBRICATING OIL FLOW









1. Oil Pump Relief Valve Operating Pressure: 6.2 - 7.8kg/cm 2 (608 - 764Kpa)
2. Regulating Valve Operating Pressure: 5.7 - 6.3kg/cm 2 (558.6 - 617.4Kpa)
3. Oil Cooler Relief Valve Opening Pressure: 2.8 - 3.4kg/cm 2 (270 - 330Kpa)
4. Oil Filter Relief Valve Opening Pressure: 0.8 - 1.2kg/cm 2 (78.4 - 117.6Kpa)
5. Oil Pressure Switch Operating Pressure: 0.3 - 0.5kg/cm 2 (29.4 - 49.0Kpa)
6. Regulating Valve: 1.8 - 2.2kg/cm 2 (176 - 216Kpa)

The 4J series engine has a full flow type lubricating system.
Lubricating oil is pumped from the oil pump to the cylinder body oil gallery through the oil cooler and the oil filter. It is
then delivered to the vital parts of the engine from the cylinder body oil gallery.
Oiling jets installed on the cylinder body spray engine oil to the piston backside faces to achieve maximum piston
cooling effect.
