11. REMOVE NO. 1 CHAIN TENSIONER ASSEMBLY See step 18
12. REMOVE CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY While holding the hexagonal portion of the No. 2 camshaft with a wrench, loosen the camshaft timing exhaust gear bolt with SST. SST: 09249-37010 NOTE: Do not remove the other 4 bolts ("TORX" bolt). If any of them is removed, replace the camshaft timing exhaust gear assembly. HINT: The bolt cannot be removed separately from the camshaft timing exhaust gear assembly due to lack of space. *1 Bolt *a Hold *b Turn Hold the hexagonal portion of the camshaft with a wrench and turn the camshaft slightly counterclockwise to release the chain sub-assembly. NOTE: Do not turn the camshaft more than necessary. HINT: Be sure to loosen the chain sub-assembly because the camshaft timing exhaust gear assembly cannot be removed with the chain tensioned. While removing the chain sub-assembly, pull out the camshaft timing exhaust gear assembly horizontally and then upward with the bolts installed.
13. INSPECT CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY Temporarily install the camshaft timing exhaust gear assembly. *a Straight Pin *b Pin Hole Insert the bolt into the camshaft timing exhaust gear assembly. Align the straight pin on the No. 2 camshaft with the pin hole in the camshaft timing exhaust gear assembly and temporarily install the camshaft timing exhaust gear assembly to the No. 2 camshaft with the bolt. NOTE: Do not install the chain sub-assembly onto the camshaft timing exhaust gear assembly in this step. Do not allow the chain sub-assembly to interfere with the camshaft timing exhaust gear assembly when installing the camshaft timing exhaust gear assembly. Inspect the lock of the camshaft timing exhaust gear assembly. Check that the camshaft timing exhaust gear assembly is locked. If the camshaft timing exhaust gear assembly dose not operate as specified, replace it. Inspect camshaft timing exhaust gear assembly operation. *a Prick a Hole *b Adhesive Tape Sealing Area *c Adhesive Tape HINT: If the camshaft timing exhaust gear assembly dose not operate as specified, replace it. Check the lock of the camshaft timing exhaust gear assembly. After cleaning the exhaust side VVT oil hole in the camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking. NOTE: Be sure to seal the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released. Prick a hole in the adhesive tape covering the oil hole as shown in the illustration. (Procedure A) Apply approximately 200 kPa (2.0 kgf/cm 2 , 29 psi.) of air pressure into the hole pricked in procedure A to release the lock pin. NOTE: If air leaks out, reattach the adhesive tape. Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying. *a Protective Tape Using a screwdriver with its tip wrapped with protective tape, forcibly turn the camshaft timing exhaust gear assembly in the retard direction (clockwise). NOTE: Be sure to keep the camshaft timing exhaust gear assembly in the retard direction. If the camshaft timing exhaust gear assembly is released, it will return to the advanced position automatically due to the force from the spring. Do not damage the camshaft timing exhaust gear assembly. HINT: Depending on the air pressure applied, the camshaft timing exhaust gear assembly may turn in the retard direction without assistance by hand. Using a screwdriver with its tip wrapped with protective tape, turn the camshaft timing exhaust gear assembly within its movable range (19 to 21°) 2 or 3 times without turning it to the most advanced position. Check that the camshaft timing exhaust gear assembly turns smoothly. *a Protective Tape Lock the camshaft timing exhaust gear assembly. NOTE: Check that the camshaft timing exhaust gear assembly locks at the most advanced position (the most advanced position of its movable range) and cannot be rotated any further. Remove the adhesive tape from the camshaft bearing cap. Remove the camshaft timing exhaust gear assembly. Remove the temporarily installed camshaft timing exhaust gear assembly.
14. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY Inspect the lock of the camshaft timing gear assembly. Check that the camshaft timing gear assembly is locked. If the camshaft timing gear assembly does not operate as specified, replace it. Inspect camshaft timing gear assembly operation. *a Make a Hole *b Adhesive Tape Sealing Area *c Adhesive Tape HINT: If the camshaft timing gear assembly dose not operate as specified, replace it. After cleaning the intake side VVT oil hole in the camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking. NOTE: Be sure to seal the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released. Make a hole in the adhesive tape covering the oil hole as shown in the illustration. (Procedure B) Apply approximately 150 kPa (1.5 kgf/cm 2 , 22 psi.) of air pressure into the hole made in procedure B to release the lock pin. NOTE: If air leaks out, reattach the adhesive tape. Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying. Forcibly turn the camshaft timing gear assembly in the advance direction (counterclockwise). HINT: Depending on the air pressure applied, the camshaft timing gear assembly may turn in the advance direction without assistance by hand. Turn the camshaft timing gear assembly within its movable range (20.5 to 22.5°) 2 or 3 times without turning it to the most retarded position. Check that the camshaft timing gear assembly turns smoothly. NOTE: Do not lock the camshaft timing gear assembly. If camshaft timing gear assembly is locked, release the lock pin again. Remove the adhesive tape from the camshaft bearing cap.
15. REMOVE CAMSHAFT BEARING CAP Uniformly loosen and remove the 10 bolts in the order shown in the illustration. NOTE: Do not loosen the other 15 bearing cap bolts in this step. HINT: Arrange the removed parts in the correct order. Remove the bolts and camshaft bearing caps in the order shown in the illustration. Immediately after removing the camshaft bearing caps, install service bolts and spacers in the order shown in the illustration. *a The removal order of the parts *b The installation order of the Service Bolts and Spacers for temporarily tightening the Camshaft Housing Sub-assembly *c Service Bolt and Spacer (Used to temporarily secure the Camshaft Housing Sub-assembly) - - Torque: 27 N*m (275 kgf*cm, 20 ft.*lbf) NOTE: If the bolts are loosened all at once, FIPG on the camshaft housing sub-assembly and cylinder head sub-assembly may peel off, resulting in oil oozing. Therefore, be sure to install the service bolts and spacers to one camshaft bearing cap at a time. Do not install the camshaft bearing caps when installing the service bolts and spacers. HINT: Arrange the removed parts in the correct order. Part number for the service bolt used to temporarily secure the camshaft housing sub-assembly: 91551-G0875 (15 bolts) Part number for the spacer used to temporarily secure the camshaft housing sub-assembly: 90387-12048 (15 spacers)
