Adjusting clearance of clutch „C"
– Place cylinder „C/D" on compressor tool -T10285- .
• Clutch „C" faces upwards.
– Place holding plate -T10281- centrally on outer plate of clutch
„C".
• Avoid any contact between holding plate and circlip.
– Fit centring pin of thrust piece -T10285/1- into drilling in holding
plate.
– Bring cylinder „C/D" into correct position on base plate of com‐
pressor tool.
• Thrust piece must be positioned centrally below thrust plate of
spindle.
– Turn spindle of compressor tool downwards.
• The markings on the inspection hole of the thrust piece must
align -arrow-.
– Apply digital depth gauge -VAS 6087- to upper rim of cylinder
„C/D" as shown in illustration.
– Bring measuring tip into contact with outer plate and note value
obtained.
– Mark measuring point on cylinder „C/D".
– Repeat measurement at two other points on outer plate (offset
by 120°) and mark measuring points.
– Determine average value from the three measurements under
load.
– Release spindle and remove holding plate.
– Use both hands to pull clutch pack upwards as far as possible
in clutch „C".
– With clutch pack pulled up as far as stop, measure distance
between upper rim of cylinder „C/D" and outer plate at one of
the points marked (second mechanic required).
– Repeat measurement at the two remaining markings on the
outer plate.
– Determine average value from the three measurements with
clutch pack pulled up as far as stop.
– Determine clearance using the following formula:
Mean value of measurements under load
(value 1 + value 2 + value 3) : 3
– Mean value of measurements with clutch pack pulled up
as far as stop
(value 1 + value 2 + value 3) : 3
= Clearance
– Subtract mean value of measurements with clutch pack pulled
up as far as stop from mean value of measurements under
load.
Clearance:
• Specification: 1.38 ... 1.83 mm
