Spark plug information and torques are for standard and hazardous location ignition systems. Waukesha Engine recommends dry spark plug installation.

NOTE: Replace spark plug gaskets every time a spark plug (except P/N 69919) is reinstalled.

Clean and regap spark plugs every 720 hours or as required.

Replace spark plugs every 1440 hours or as required.

When regapping spark plugs, examine each spark plug for cracked porcelain, leakage and burned electrodes.

Examine spark plug firing end for abnormal spark plug conditions.

NOTE: Spark plugs 60999Y and 60999U are for use with early integral coils. Spark plugs 69919, 60999S and 60999W are used with CSA flange mounted coils.

NOTE: The crankshaft should already be removed from the crankcase. Refer to Chapter 2.05 Crankcase Component Removal “Crankshaft Removal” for additional information. CRANKSHAFT REMOVAL

1. Set crankcase upside down in a suitable location.

2. Remove main bearing cap crossbolts from sides of crankcase. Make sure that bearing caps are marked and matched to crankcase location.

Do not spread the crankcase more than 0.006 in. (0.15 mm). Use a dial indicator to measure the spread of the crankcase sides. Disregarding this information could result in product damage.

3. Install crankcase spreader tool P/N 472002 (see Figure 2.05-57) between bearing caps #1 and #2. Adjust tool and spread crankcase. Remove bearing caps.

4. Move spreader tool between caps #3 and #4. Remove and repeat sequence for rest of main bearing caps (see Figure 2.05-57).

5. Center main bearing cap also contains a thrust washer on either side of bearing cap. Thrust washer can be identified by a tab in bearing cap (see Figure 2.05-58).

6. Left side #5 and #6 crossbolts have special washers and O--rings (see Figure 2.05-59). These crossbolts pass through oil passages and must be reinstalled in their original locations.

Warning: Always wear protective clothing when bleeding the cooling system on a heated engine.

Caution: Air can be drawn into the engine through small leaks in the jacket water system.

Initial Bleed: Open each air bleed petcock prior to engine startup. Close petcock when hissing stops and water begins to flow out in a solid steady stream.

Check Bleed: Start engine and reopen each petcock. Close petcock when hissing stops and water begins to flow out in a solid steady stream.

Final Bleed: Once temperature of jacket water circuit has stabilized, reopen each petcock. Close petcock when water begins to flow out in a solid steady stream.
