TIMING GEAR TRAIN

REMOVAL To service gear train and related parts, with the

exception of the crankshaft, engine normally need not be removed. If engine must be removed, see Group 5 of this section.

Shaft Gear

Fig. 22-Timing Gear Train

Whenever an engine is being completely reconditioned or the crankshaft is being removed, the engine front plate with gear assemblies should be removed from the engine using the following steps:

1. Remove timing gear cover.

2. Remove hex. nuts from the oil pump and injection pump drive gears and cap screws from upper and lower idler gears.

Litho in U.S.A.

3. Remove upper and lower idler gears from engine front plate. Attach a puller to oil pump gear and pull gear from shaft. NEVER PRY GEAR FROM SHAFT.

4. Remove oil pump (Group 15).

5. Remove fuel injection pump and drive gear (Group 25).

6. Remove camshaft.

REPAIR

Checking Gear Train Backlash

If gear train noise is noted at the time of disassembly, it usually indicates excessive gear lash or damaged gear teeth.

Specified timing gear train backlash is as follows:

Gear Backlash

Camshaft to upper idler ......... 0.0028 to 0.0135 inch [0.0711 to 0.3429 mm]

Injection pump to upper idler ...................................... 0.0028 to 0.0135 inch

[0.0711 to 0.3429 mm] Crankshaft to upper idler ....... 0.0027 to 0.0116 inch

[0.0686 to 0.3480 mm] Oil pump to left balancer ...... 0.0020 to 0.0140 inch

[0.0508 to 0.3556 mm] Oil pump to lower idler .......... 0.0027 to 0.0137 inch

A CAUTION: Escaping fluid under pressure can have sufficient force to penetrate the

skin causing serious personal injury. Before disconnecting lines, be sure to relieve all pressure. Before applying pressure to the system, be sure all connections are tight and that lines and hoses are not damaged. Fluid escaping from a very small hole can be almost invisible. Use a piece of cardboard or wood, rather than the hands to search for suspected leaks.

If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if proper medical treatment is not administered immediately.
