(1) Remove the injection pipe assembly. CAUTION* When disconnecting each injection pipe from the injection pump side delivery valve holder, grasp the holder with a wrench to prevent it from loosening.* After removing the pipe assembly, plug the nozzle holders and delivery valve holders to prevent intrusion of dust.(2) Disconnect the glow plug lead wire.(3) Loosen the alternator bracket bolts and dismount the alternator.(4) Disconnect the air breather hose.(5) Remove the rocker cover.(6) Remove the rocker shaft assembly.(7) Loosen the cylinder head mounting bolts in the numerical order illustrated at right and remove the cylinder head assembly (including the intake and exhaust manifold).(8) Remove the cylinder head gasket.Clean the cylinder head and the cylinder block surface from which the gasket has been removed.(9) Remove the nozzle holder assemblies and glow plugs from the cylinder head.(10) Remove the intake manifold and exhaust manifold from the cylinder head.(11) Remove the valve retainers, valve springs, and valves from the cylinder head. CAUTION* When removing each valve retainer, depress the retainer against the valve spring and remove the retainer lock. Identify each valve by putting a mark indicating the number of cylinder from which the valve is removed.(12) Remove the valve stem seals.

Removing ValvesInspection and Repair
Inspection of Cylinder HeadReplacement of Valve Guide
If a valve guide is found defective, replace it.1. RemovalPress the guide at its upper end and pull it out to the valve seat side.2. Installation (Press-fitting)Press-fit the guide from the upper side of the cylinder head to a height of 14 0.5 mm from the valve spring seat face.
Press-fitting Valve GuideRepair of Valve Seat
If a valve seat is found defective, reface it or replace the cylinder head. CAUTION* When checking valve sinkage, the valve guide must be in the normal condition.* Resurface the valve seat so that it contacts the mid-portion of the valve face.
Checking Valve Sinkage
Resurfacing Valve Seat (Common to intake and exhaust valves)Installation
Installation of the cylinder head is in the reverse order of removal. Pay attention to the following:(1) Renew the cylinder head gasket. No application of sealant is necessary. On the upper front of the gasket is engine model to which that gasket is applicable. Be careful not to confuse with a gasket for other engine model.(2) Tighten the cylinder head bolts in the numerical order shown in the figure at right, going through that order two or three times. Tighten each bolt a little at a time until all are tightened to the specified torque.(3) When connecting the injection pipe assembly, loosen the pipe clamp.When tightening the nut at each end of pipe, grip the nozzle holder or delivery valve holder with a wrench to prevent it from being turned together with the nut.Also, take care not to allow dust to enter the fuel line.

(1) Dismount the cylinder head assembly.(2) Depress the valve retainer (to compress the valve spring) and remove the retainer lock.(3) Remove the valve.
Removing Valve and Valve SpringInspection and Repair
If any parts found defective, repair or replace them.
Inspection of Valve and Valve Spring
Valve Spring Tester1. Repair of valve faceIf the valve face is found worn down, resurface with a valve refacer. If margin of the resurfaced valve exceeds service limit, replace the valve.2. Repair of valve stem endIf the valve stem end has been indented by wear, flatten with an oil stone.
Inspecting ValveInstallation
(1) Install the valves and valve springs, referring to notes shown in the figure below.(2) Mount the cylinder head assembly.(3) Adjust the valve clearances.
Installation of Valve Spring CAUTION Be careful not to damage the spring and stem seal by excessively compressing the spring when installing the valve spring.
