Repair procedures: Installation
WARNING: This page is about a different variant/trim than selected.
CAUTION:
Do not reuse the injector retaining clip, O -ring, backup ring, washer seal or combustion sealing. Once an injector is removed, the five components must be replaced with new ones.
- Combustion seal
- Washer seal
- Backup ring
- O-ring
- Retaining clipNOTE:
- Item 1, 3 and 4 are supplied in a single kit.
CAUTION:- Install the component with the specified torques.
- Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
CAUTION:- Apply engine oil to the injector O-ring.
CAUTION:- Do not reuse the delivery pipe mounting bolts. Once the delivery pipe is removed, the bolts must be replaced with new ones.
CAUTION:- When inserting the injector, be careful not to damage the injector tip.
CAUTION:- When replacing the washer seal, the steal plate (A) part should be faced the cylinder installation part and the rubber plate (B) part should be faced the injector body part.
CAUTION:- Do not reuse the combustion seal.
- Be careful not to apply engine oil on the combustion seal ring.
CAUTION:- Avoid dropping the fuel pipe (including injectors) or bumping it into any hard objects since damage to the internal components may occur. If necessary, visually inspect and confirm proper operation with performance tests prior to reuse.
- Before installing the injector into the cylinder head, clean the injector hole and avoid contaminants from entering inside the injector hole. When installing the injector, avoid bumping the injector tip into any of the surrounding components since the tip may become damaged from the impact.
- When fastening the three fuel delivery pipe mounting bolts, fully hand-tighten first, and then tighten in the proper sequence (1) ((2)) → (3) in several cycles up to the specified torque. The delivery pipe should move less than 1/8 inch (approx.3mm), whenever each bolt is tightened.
- Installation is reverse of removal.
