Note
Cover the paths with a piece of cloth when applying pressure to keep oil from spraying.
| *a | Advance Side Path |
| *b | Retard Side Path |
| *c | Hold Pressure |
| *d | Decompress |
Check that the camshaft timing exhaust gear assembly turns in the retard direction when reducing the air pressure applied to the advance side path.
Tech Tips
The lock pin is released and the camshaft timing exhaust gear assembly turns in the retard direction.
When the camshaft timing exhaust gear assembly moves to the most retarded position, release the air pressure from the advance side path, and then release the air pressure from the retard side path.
Note
Be sure to release the air pressure from the advance side path first. If the air pressure of the retard side path is released first, the camshaft timing exhaust gear assembly may abruptly shift in the advance direction and break the lock pin or other parts.
Check for smooth rotation.
Turn the camshaft timing exhaust gear assembly within its movable range (21.5 to 23.5°) 2 or 3 times, but do not turn it to the most advanced position. Make sure that the gear turns smoothly.
Note
When the air pressure is released from the advance side path and then from the retard side path, the gear automatically returns to the most advanced position due to the advance assist spring operation, and locks. Gradually release the air pressure from the retard side path before performing the smooth rotation check.
Remove the vinyl tape and rubber pieces from the No. 2 camshaft.
Remove the bolt and camshaft timing exhaust gear assembly Click here.
