Engine Break-In Period
The break-in period for a Polaris RANGER engine is defined as
the first 25 hours of operation, or the time it takes to use 2 full
tanks of gasoline. No single action on your part is as important
as a proper break-in period. Careful treatment of a new engine
will result in more efficient performance and longer life for the
engine. Perform the following procedures carefully:
1. Fill fuel tank with unleaded or leaded fuel which has a
minimum pump octane number of 87= (R+ M)/2.
2. Check oil level indicated on dipstick. Add oil if necessary
(Refer to Chapter 2, “Engine Oil Level” ).
3. Drive slowly at first to gradually bring engine up to
operating temperature.
4. Vary throttle positions. Do not operate at sustained idle or
sustained high speed.
5. Perform regular checks on fluid levels, controls and all
important bolt torques.
6. Pull only light loads during initial break-in.
7. Change oil and oil filter after break-in period at 25 hours.
Engine Lubrication Specifications
Oil Pressure Test
1. Remove blind plug/sender from left side of crankcase.
2. Insert a 1/8 NPT oil pressure gauge adaptor into the
crankcase and attach the gauge.
3. Start engine and allow it to reach operating temperature,
monitoring gauge indicator.
NOTE: Use only Polaris PS-4 PLUS 2W-50 Synthetic
Engine Oil.
