Usage:

This LUBRICATION AND MAINTENANCE CHART lists those items commonly ordered on this engine which require servicing.

The items are listed in the order they appear in the LUBRICATION AND MAINTENANCE PROCEDURES section of this Guide. Items requiring periodic maintenance precede the items which require servicing at indefinite intervals. The time intervals are expressed in SERVICE METER UNITS which are the numbers displayed on the engine's service meter. Use the daily readings of the Service Meter to determine maintenance intervals. For those areas which require periodic maintenance which cannot be given a definite service hour, see the column "WHEN TO SERVICE" following each of these items listed.

Perform required maintenance at multiples of each unit. "EVERY 10" means perform that maintenance at 10, 20, 30, etc., service meter units. Similarly, "EVERY 50" means perform that service at 50, 100, 150, etc., service meter units. For items requiring service intervals of 125 through 1000 service meter units, service each item at the time indicated. After each 1000 units, repeat the sequence at the same interval. "EVERY 2000" means to service the item every 2,000, 4,000, 6,000, etc., hours, or once each 12 months.

For items marked (*) see "KEY TO FUELS, LUBRICANTS AND WATER" on Page C-3 of this chart. "Page" refers to the page number in the LUBRICATION AND MAINTENANCE PROCEDURES where the service procedure is detailed for that item.
