sprocket, idler pulley, injection pump pulley and belt ten-
sioner are clean and free from oil and water.
+Align white lines on timing belt with punch mark on cam-
shaft sprocket, crankshaft sprocket and injection pump
pulley.
+Installation should be carried out when engine is cold.

VALVE OIL SEAL
1. Remove timing belts.
2. Remove camshaft sprocket 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. 6
cylinders. Valve spring seats should not be removed.
3) Install new valve oil seals for No. 1 and No. 6 cylinders as
illustrated. Reinstall valve springs. (narrow pitch side toward
cylinder head)
4) Install valve spring retainers on intake valves and valve rotators
on exhaust valves, and remount valve assembly.
5) Set No. 2 cylinder at TDC.
6) Replace valve oil seals for No. 2 and No. 5 cylinders according
to steps 2) and 3).
7) Set No. 3 cylinder at TDC.
8) Replace valve oil seals for No. 3 and No. 4 cylinders according
to steps 2) and 3).
9) Install valve lifters in original positions.
