GENERAL INFORMATION

1. Support the UTV on a work stand with the rear wheel off the ground.
2. Remove the air filter assembly Open and secure the throttle so it is at its wide-open position.
3. Remove the spark plug.
4. Install the threaded hose adapter from the leakdown kit. Then install the leakdown gauge onto
the hose.
5. Remove the ignition timing hole cap from the left crankcase cover.
6. Remove the crankshaft hole cap from the right crankcase cover.
NOTE
Because the following test is performed with the cylinder head
cover installed on the engine, the camshaft lobes cannot be
viewed to ensure that the engine is positioned at TDC on its
compression stroke. To determine when the engine is
approaching TDC on its compression stroke, or whether it is
360°off. Observe the following two indicators to predict engine
position. First, when aligning the index marks in Step7, listen for
pressure building inside the combustion chamber. Indicating
that the piston is moving to TDC on its compression stroke.
Second, view the gauge on the leakdown tester when turning
the engine. As the piston moves toward TDC on its compression
stroke, compression building inside the combustion chamber
may cause the gauge needle to move slightly. If the crankshaft
is 360°off, these indicators will not be present.
NOTE
The decompress or mechanism will click loudly once during
each crankshaft revolution. This is normal.
7. Use hex socket on the primary drive gear mounting bolt and turn the crankshaft clockwise and align
the TDC mark on the flywheel with the index mark on the left crankcase cover Remove the hex socket
from the primary drive gear.
8. Perform the following to lock the transmission so the engine remains at TDC on
it
s compression
stroke when performing the leakdown test:
WARNING
Do not attempt to lock the engine by trying to use a tool to
hold the Allen bolt on the end of the crankshaft. Once the
combustion chamber becomes pressurized, any
crankshaft movement can throw the tool away from the
engine under considerable force, attempting to hole the
tool can cause serious injury. Engine damage may also
occur to the crankshaft or right crankcase cover. Lock the
engine as described in this procedure.
