REMOVAL
Remove guard and drive belt from vehicle.
Remove the screw, and washer then pull the driv-
en pulley from the shaft.
DISASSEMBLY
Use spring compressor (P/N 529 035 524).
Remove snap ring no. 2 and washer no. 3 to dis-
assemble the outer cam and the 2 pulley halves.
CLEANING
6, Bushing
During break-in period (about 10 hours of use), te-
flon from bushing moves to cam or shaft surface.
A teflon over teflon running condition occurs, lead-
ing to low friction. So it is normal to see gray teflon
deposit on cam or shaft. Do not remove that de-
posit, it is not dust.
When a dust deposit has to be removed from the
cam or the shaft, use dry cloth to avoid removing
transferred teflon.
Pulley Half Cleaning
Use Pulley flange cleaner (P/N 413 711 809).
INSPECTION
6, Bushing
Check for cracks, scratch and for free movement
when assembled to fixed half.

inside edge of cam slider shoe slope base is worn
to 1 mm (.039 in) or less.
1. Measure thickness of slope base here
2. Sliding pulley side

ASSEMBLY
4, Cam Slider Shoe
When replacing slider shoes, always install a new
set (3 shoes) to maintain equal pressure on the
cam.
Assemble driven pulley components by reversing
the disassembly procedure.
19, Cam
Coat cam interior with anti-seize lubricant.
INSTALLATION
CAUTION: Always apply anti-seize lubricant
(P/N 413 701 000) on the shaft before final pul-
ley installation.
ADJUSTMENT
Refer to PULLEY DISTANCE AND ALIGNMENT to
adjust pulley distance. Adjust drive belt height in
driven pulley. Turn screws

ingly.
5, Spring
General
It is usual to experience spring setting during
breaking period of a new spring. The factory spring
preload is slightly higher (about 1 kg (2 lb)) to com-
pensate for spring setting. Specifications in TECH-
NICAL DATA are applicable after break-in period
(about 10 hours of use).

