1999 NISSAN PRIMERA timing belt

VALVE OIL SEAL
1. Remove both timing belts.
2. Remove camshaft sprockets and back covers.
3. Remove camshaft brackets by loosening bracket nuts from
center to outside in two or three stages.
4. Remove camshaft oil seals and camshaft.
5. Remove valve lifters and mark order No. on each lifter.
6. Replace valve oil seal according to the following procedure.
When replacing valve oil seal, set the corresponding piston at
TDC. Failure to do so causes the valve to drop into the cylin-
der.
1) Set No. 1 cylinder at TDC.
2) Remove valve springs and valve oil seals for No. 1 and No. 4
cylinders. Valve spring seats should not be removed.
3) Install new valve oil seals for No. 1 and No. 4 cylinders as
illustrated. Reinstall valve springs. (Narrow pitch side toward
cylinder head)
4) Install valve spring retainers on intake valves and valve rota-
tors on exhaust valves, and remount valve assembly.
5) Set No. 2 cylinder at TDC.
6) Replace valve oil seals for No. 2 and No. 3 cylinders accord-
ing to steps 2) and 3).
7) Install valve lifters in original positions.
CAMSHAFT AND CRANKSHAFT OIL SEAL INSTALLING
DIRECTION AND MANNER
IWhen installing camshaft and crankshaft oil seals, be
careful to install them correctly, as shown in the figure.
IApply engine oil to oil seal lip, outer face, camshaft and
bracket.
IWipe off excess oil after installing oil seal.
CAMSHAFT OIL SEALS
1. Remove timing belts, sprockets and back covers.
2. Pull out oil seal with a suitable tool.

Removal
1. Drain coolant and disconnect front exhaust pipe from manifold.
2. Remove water hoses, air duct and intake manifold.
3. Remove heat shield and exhaust manifold.
4. Remove rocker cover and injection tubes.
5. Remove both timing belts.
Set No. 1 cylinder at TDC on its compression stroke. Refer to
ªTIMING BELTº (EM-134).
After timing belts have been removed, do not rotate crankshaft
and/or camshaft separately as valves will hit piston heads.
6. Remove cylinder head bolts in numerical order as shown in the
figure.
Disassembly
1. Remove front camshaft sprocket plate, front and rear sprock-
ets using special service tool or a suitable tool, and front back
cover.
2. Remove camshaft brackets in order from outside to inside.
ILoosen camshaft bracket nuts in two or three stages.
3. Remove camshaft and oil seals.
4. Remove valve lifters.
For valve lifter
IAttach tags to valve lifters for identification.
5. Remove valve component parts using special service tool or a
suitable tool.
IKeep each valve and its components together and mark
them so they can be reassembled in their original posi-
tions.
6. Remove valve oil seals using special tool.
