a. Loosen mounting bolts in the order from 32 to 1 as shown in the figure.
b. Pry off case by moving the suitable tool.
- Use the seal cutter [SST: KV10111100 (J-37228)] to cut liquid gasket for removal.
  CAUTION:
- Never use a screwdriver or something similar. Failure to do this may cause damage to the parts.
- After removal, handle front timing chain case carefully so it does not tilt, cant, or warp under a load.
  c. Remove dowel pin from timing chain case.
Remove front oil seal from front timing chain case using a suitable tool.
Use a screwdriver for removal.
CAUTION:
Never damage front timing chain case.
Remove timing chain tensioner as follows:
a. Insert plunger A into tensionet 1.
b. Insert a wire such as clip (B) with the plunger inserted.
c. Remove chain tensioner.
Remove internal chain guide and slack guide.
Remove timing chain (LH) and (RH).
Remove oil pump drive chain. Refer to Removal and Installation.
Use a scraper to remove all traces of old liquid gasket from front and rear timing chain cases and oil pan (upper), and liquid gasket mating surfaces.
CAUTION:
Never allow gasket fragments to enter oil pan.
Remove old liquid gasket from bolt hole and thread.

INSTALLATION

CAUTION:
Do not reuse 0-rings.

NOTE:

If a timing chain is removed, carry out the teach of “Electric IVT Control Actuator Position Learning”. Refer to Description.
If an intake camshaft sprocket or exhaust camshaft sprocket are removed, carry out the teach of “Electric IVT Control Actuator Position Learning”. Refer to Description.
If an electric intake valve timing control actuator, carry out the teach of “Idle Air Volumee Learning. Refer to Description.
The below figure shows the relationship between the matching mark on each timing chain and that on the corresponding sprocket, with the components installed.

NISSAN VR30DDTT OEM Primary Timing Chain-18

Check that dowel pin A and crankshaft key 1 are located as shown in the figure. (No. 1 cylinder at compression TDC)
NOTE
Though camshaft does not stop at the position as shown in the figure, for the placement of cam noses, it is generally accepted camshaft is placed for the same direction of the figure.

Camshaft dowel pin

| : At cylinder head upper face side in each bank.
Crankshaft key
| : At cylinder head side of bank 1.
2. Install the crankshaft sprocket and the oil pump drive related parts with the following procedure:
a. Install the crankshaft sprocket, the oil pump drive chain, and the oil pump sprocket at the same time.
NOTE:
There is no matching mark in the oil pump drive related parts.
b. Hold the top of the oil pump shaft using the TORX socket (commercial service tool), and then tighten the oil pump sprocket nuts.
c. Install chain tensioner.

  * Check that the tension is applied to the oil pump drive chain after installing.

Install timing chain as follows:
a. Install crankshaft sprocket
- Check the matching marks on crankshaft sprocket face the front of the engine.
  b. Install timing chain.
Install internal chain guide and slack guide. CAUTION:
Never overtighten slack guide 1 mounting bolts 2. It is normal for a gap A to exist under the bolt seats when mounting bolts are tightened to the specification.
Install the timing chain tensioner.
Disconnect clip from chain tensioner.
Check again that the matching marks on sprockets and timing chain have not slipped out of alignment.
Install new O-rings on cylinder head.
CAUTION:
