5.
Tighten each spring retainer nut on the clutch
housing exactly 2 revolutions to restore clutch to
original setting pressure. See "Clutch Assembly"
on page 26 for exact spring length.
6.
The clutch should be checked during the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
Clutch Disassembly
Refer to Figure 5-4 on page 26:
Disassembly of the clutch is simply a matter of removing
the spring retainer nuts (#1), springs (#2), and bolts (#3)
from the assembly. Each friction disc (#4) must then be
separated from the metal surface adjacent to it.
Clutch Inspection
Inspect all parts for excessive wear and condition. Clean
all parts that do not require replacement.The original
friction disc thickness is 1/8" (3.2 mm) and should be
replaced if thickness falls below 3/64" (1.1 mm). If
clutches have been slipped to the point of “smoking”, the
friction discs may be damaged and should be replaced.
Heat build-up may also affect yoke joints.
Clutch Assembly
Refer to Figure 5-4:
Reassemble each friction disc (#4) next to the metal
plate it was separated from. Install bolts (#3) through the
end plates and intermediate plates as shown. Place
springs (#2) over the bolts and secure with nuts (#1).
Refer to Figure 5-4 & Figure 5-5:
Install new friction discs if needed and reassemble all
components in proper order. Progressively tighten each
spring retainer bolt until spring length is 1.110" to 1.120".
Skid Shoe Maintenance
Refer to Figure 5-6:
