4.5 Engine Lubrication
Check engine oil daily before starting engine.
DO NOT operate engine if oil level is below ADD mark on dipstick.
Always keep oil level within the crosshatch pattern or “full” mark on
dipstick.
Change oil after first 100 hours of operation and every 250 hours
thereafter. Refer to the engine manufacturer’s Operator’s Manual for
lubrication specifications.
Break-in Service
4.5.1 This engine is factory-filled with John Deere Engine Break-in Oil.
Operate the engine at heavy loads with minimal idling during the
break-in period. DO NOT exceed 100 hours of operation with break-in
oil.
4.5.2 If the engine has significant operating time at light load, or makeup oil
is required in the first 100 hour period, a longer break-in period may be
required. In these situations, an additional 100 hour break-in period is
recommended using a new change of John Deere Engine Break-In Oil
and a new John Deere oil filter.
NOTICE: DO NOT add makeup oil until the oil level is BELOW the
ADD mark on dipstick. John Deere Engine Break-In Oil (TY22041)
should be used to make up any oil consumed during the break-in
period.
4.5.3 During the first 20 hours, avoid prolonged periods of no load or
sustained maximum load operation. If engine is to run for longer than
5 minutes without a load, shut unit down.
4.5.4 After the first 100 hours, change engine oil and replace engine oil filter.
Fill crankcase with seasonal viscosity grade oil.
