PRIMARY TRANSMISSION SYSTEM 8-11
CLUTCH ALIGNMENT
GENERAL INFORMATION
Since the two clutches are rigidly mounted, the only alignment
dimension that requires inspection is the distance between the
inside of the fixed sheave of the primary clutch (inner sheave)
and the inside of the fixed sheave of the secondary clutch (outer
sheave). This alignment data serves as a reference for the
assembly as well as defining the dimensions that offer a
satisfactory deflection of the belt.
The objective of the adjustment of alignment of the clutches is to
guarantee the efficiency of the transmission system.
Furthermore, an efficient operation as well as a minimum of
wear on the belt can only be obtained when the clutches are
properly aligned.
▼
CAUTION
Before verifying the adjustment of the pulleys, make sure
the rear suspension has been installed on the vehicle and
that the tension and alignment of the track have been
checked. Always check the adjustment of the clutches
whenever the suspension is adjusted.
◆
WARNING
If the alignment procedure for the clutches is not carried
out correctly, the snowmobile could move slowly forward
at low speed.
The alignment data takes into account the following dimensions:
X = The distance between the inside of the fixed sheave of the
primary clutch (inner sheave) and the inside of the fixed sheave
of the secondary clutch (outer sheave) =
15mm (0.590 in)
●
NOTICE:
If possible, using a flatbar of length 55-60 cm (24 in) and a width
of 15mm (0.590 in) can be used as a guide to space the two
sheaves apart correctly, in one operation.
PROCEDURE
o
Remove the drive belt.
o
While turning and pushing the sliding half-pulley, open
the secondary clutch. Insert the flatbar into the
secondary clutch and the primary clutch.
o
If there is a gap on either side of the flatbar that rests in
the two clutches, add shims (P/N 504108200) to either
side of the secondary clutch to re-align the system.
