Fig. 1-Measuring Valve LiftPosition dial indicator on valve rotator or valve spring cap (Fig. 1). (Be sure valve is fully closed and rocker arm moves freely).Zero dial indicator.
Fig. 2-Valve LiftManually rotate crankshaft clockwise, as viewed from front end.Repeat valve lift check on each valve. Lift should be:Intake ... 0.460 to 0.490 inch(11.68 to 12.45 mm)Exhaust ... 0.456 to 0.482 inch(11.58 to 12.24 mm)Timing Gear Cover
Removal
Fig. 3-Accessory RemovalRemove fan (1, Fig. 3) and fan belt(s) (2).Remove vibration damper (3) (Group 0401).Remove oil pan (4) (Group 0407).
Fig. 4-Oil Pressure Control ValveRemove oil pressure control valve (Engines 3-164D, 3-179D, 4-219D, 4-239D, 4-239T, 6-329D, 6-359D, and 6-359T) (Group 0407) (Fig. 4). Count adjusting washers for reassembly.
Fig. 5-Attaching HardwareRemove timing gear cover attaching nuts and cap screws (Fig. 5).Repair
Remove gasket residue from cylinder block and timing gear cover.Inspect timing gear cover for cracks and breaks.Replace crankshaft front oil seal (Group 0402).Installation
Fig. 6-Install Timing Gear CoverApply a light coat of high-temperature grease to the lip of the crankshaft front oil seal.Using a new gasket, install timing gear cover on cylinder block with a slight twisting motion. IMPORTANT: Be careful not to invert crankshaft front oil seal lip.
Fig. 7-Accessory InstallationInstall oil pan (4, Fig. 7) (Group 0407).Install vibration damper (3) (Group 0401).Install alternator and fan belt (2), and fan (1).Adjust belt tension (Group 9010).Crankshaft Front Oil Seal
Removal
Remove timing gear cover (Group 0402).Drive crankshaft front oil seal out of timing gear cover.Installation
Coat outer surface of seal with non-hardening gasket cement and inner surface with high temperature grease.Support the oil seal bore area of the timing gear cover.
Fig. 8-JD-250 DriverUsing JD-250 Driver (Fig. 8), press oil seal to bottom of bore with spring-loaded lip facing inward.Camshaft
Removal
Remove timing gear cover (Group 0402).Remove flywheel and flywheel housing (Group 0433).Remove fuel transfer pump (Group 0421).Rotate crankshaft clockwise, as viewed from the front end, until number one piston is at top dead center on its compression stroke (both) rocker arms for number one cylinder will be loose).
Fig. 9-JD-254 Timing ToolUsing JD-254 Timing Tool (1, Fig. 9), align timing mark on camshaft gear with the timing tool.Remove rocker arm assembly and push rods (Group 0402).
Fig. 10-D-15001-NU Magnetic Lifter HolderUsing D-15001-NU Magnetic Lifter Holder (Fig. 10), raise cam followers off camshaft lobes. Secure holders so that cam followers will not drag on cam lobes.
Fig. 11-Camshaft End PlayPosition a dial indicator on the camshaft gear (Fig. 11).Push camshaft to the rear of the engine as far as possible.Zero dial indicator.Using two screwdrivers or pry bars, move camshaft to the front of the engine as far as possible.Read dial indicator.Camshaft end play (new) ... 0.003 to 0.009 inch(0.08 to 0.23 mm)Camshaft end play (max.) ... 0.015 inch(0.38 mm)
Fig. 12-Camshaft End Play
Fig. 13-Camshaft Gear BacklashPosition a dial indicator against a tooth on the camshaft gear (1, Fig. 13).Hold upper idler gear (2) securely.Rotate camshaft gear back-and-forth.Note variation on dial indicator.Camshaft gear backlash ... 0.003 to 0.014 inch(0.08 to 0.36 mm)
