MAINTENANCE
MAIN BEARING
Clean crankshaft thoroughly and oil main and connecting rod
bearings with Polaris engine oil. Carefully check each main
bearing on the shaft.
Due to extremely close tolerances, the bearings must be
inspected visually, and by feel. Look for signs of
discoloration, scoring or galling. Turn the outer race of each
bearing. The bearings should turn smoothly and quietly. The
inner race of each bearing should fit tightly on the crankshaft.
The outer race should be firm with minimal side to side
movement and no detectable up and down movement. Replace
any loose or rough bearings.
CONNECTING ROD (BIG END) BEARING
Specialized equipment and a sound knowledge of crankshaft
repair and straightening is required to perform crankshaft
work safely and correctly. Crankshaft repair should be
performed by trained Polaris service technicians in a properly
equipped shop.
Measure connecting rod big end side clearance with a feeler
gauge. 500/600 Liberty
t
engines should have a clearance of
.011 - .030
"
(.28 -.75mm) and 700/800/900 Liberty
t
engines should have .011 - .028
"
(.28 - .70mm) and be equal
on all rods within .002
"
(.05mm).
Rotate the connecting rod on the crankshaft and feel for any
rough spots. Check radial end play in rod by supporting rod
against one thrust washer and alternately applying up and
down pressure. Replace bearing, pin, and thrust washers if
side clearance is excessive or if there is any up and down
movement detectable in the big end bearing.
WRIST PIN BEARING
1.
Clean the end of the connecting rod and inspect inner bore
with a magnifying glass. Look for any surface
irregularities including pitting, wear, or dents.
2.
Run you fingernail around the inside of the rod and check
for rough spots, galling, or wear.
3.
Oil and install needle bearing and pin in connecting rod.
4.
Rotate pin slowly and check for rough spots or any
resistance to movement.
5.
Slide pin back and forth through bearing while rotating
and check for rough spots.
6.
With pin and bearing centered in rod, twist ends back and
forth in all directions to check for excessive axial play.
7.
Pull up and down evenly on both ends of pin to check for
radial play.
8.
Replace pin and bearing if there is any resistance to
rotation or excessive axial or radial movement. If play or
roughness is evident with a new pin and bearing, replace
the connecting rod.
Within .002” (.05mm)
