Attach the clutch/idler assembly to the tractor frame
as follows. Hook the assembly's notched arms onto
the two shoulder bolts you assembled to the inside
of the tractor frame. Lift the front of the assembly
and attach it to the R.H. and L.H. hanger brackets
using two pivot lock pins and 1/8" hairpin cotters.
See figure 21.
TENSIONING CHAIN
ELECTRIC ATTACHMENT CLUTCHES
Turn the clutch/idler assembly upside down and
place the extra tensioning chain through the left
front hole as shown in figure 19.
Hook the loose spring through the end of the
tensioning chain. See figure 20.
Hook the other end of the spring onto the bottom of
the bolt and nut which secure the idler pulley to the
upper idler arm. Hold the bolt head and assemble a
3/8" hex lock nut onto the bolt, leaving it loose
enough for the spring to pivot freely between the
two nuts. See figure 20.
Attach a 3/32" hairpin cotter to the chain, placing it
in the fifth link from the spring. See figure 20.
FIGURE 19
FIGURE 21 RIGHT SIDE VIEW
Assemble the short "V" belt onto the engine pulley
and then onto the large pulley on top of the clutch/
idler assembly. The belt must be placed to the
inside of the engine pulley keeper, the idler pulley
and the keeper bolt located beside the large pulley.
See figure 22 on page 13.
Place tension on the belt by pulling the left side
tensioning chain out as far as the 5/64" hairpin
cotter will allow. Secure the chain in this position by
inserting a 1/8" hairpin cotter through the chain.
See figure 22 on page 13.
IMPORTANT: Do Not assemble the "V" belt around
the outside of the engine pulley keeper or the
keeper bolt.
