Vacuum Pump (For 1Gd-Ftv) -- Installation |
| 1. INSTALL VACUUM PUMP UNION |
Install the 2 new gaskets and the vacuum pump union with the union bolt.
- Torque:
- 14 N*m{140 kgf*cm, 10 ft.*lbf}
- HINT:
- Check that the stopper of the vacuum pump union with union is securely held on the vacuum pump assembly.

| 2. INSTALL CAMSHAFT OIL SEAL RETAINER |
- NOTICE:
- If the camshaft oil seal retainer is dropped, replace it with a new one.
Before installing a new camshaft oil seal retainer, clean the installation surface of the No. 3 camshaft bearing cap and cylinder head sub-assembly and remove any foreign matter.
Using SST and a hammer, tap in a new camshaft oil seal retainer to the No. 3 camshaft bearing cap and cylinder head sub-assembly as shown in the illustration.
- SST
- 09223-46011
- Standard depth:
- 0 to 0.8 mm (0 to 0.0315 in.)

Install the vacuum pump assembly with the 3 bolts.
- Torque:
- 21 N*m{214 kgf*cm, 15 ft.*lbf}
- NOTICE:
- After installation, check that there are no gaps between the matching surfaces and that the vacuum pump assembly is not installed at an angle.
| 4. CONNECT NO. 1 VACUUM TRANSMITTING HOSE |
Connect the No. 1 vacuum transmitting hose to the vacuum pump assembly.
| 5. REMOVE ENGINE ASSEMBLY TO ENGINE STAND |
- NOTICE:
- Pay attention to the angle of the sling device as the engine assembly or engine hangers may be damaged or deformed if the angle is incorrect.
- With the exception of installing the engine assembly to an engine stand or removing the engine assembly from an engine stand, do not perform any work on the engine assembly while it is suspended, as doing so is dangerous.
Attach the engine sling device and hang the engine assembly with the chain block.
Remove the engine assembly from the engine stand.
