The nominal torque values listed are for general use only with the assumed
wrenching accuracy of 20%, such as a manual torque wrench.
DO NOT use these values if a different torque value or tightening procedure is
given for a specific application.
For lock nuts, for stainless steel fasteners, or for nuts on U-bolts, see the
tightening instructions for the specific application.
Replace fasteners with the same or higher property class. If
higher property class fasteners are used, tighten these to the
strength of the original.
• Make sure that fastener threads are clean.
• Apply a thin coat of Hy-Gard™ or equivalent oil under the head and on the threads of the fastener, as shown in the following image.
• Be conservative with the amount of oil to reduce the potential for hydraulic lockup in blind holes due to excessive oil.
• Properly start thread engagement.

Upgrade the Combine Straw Chopper with
Vane Tailboard or PowerCast™ Tailboard
Only
ZX387488 —UN—21JAN20
IMPORTANT: The purpose of this attachment is to
upgrade the original straw chopper with vane
tailboard or PowerCast™ tailboard. If the
straw chopper is equipped with an Advanced
PowerCast™ tailboard, then additional parts
are required to convert. If necessary, order
the parts through the regular parts channel.
Contact your John Deere dealer.
IMPORTANT: For all adjustment and removal/installation procedure, always refer to the
relevant combine Repair Technical Manual
and Operator’s Manual.
ZX387489 —UN—21JAN20
NOTE: Installation procedure is for a S700 Series
Combine with a PowerCast™ tailboard and must
be followed for any other system.
If equipped with an Advanced PowerCast™ tailboard,
then the tailboard must be removed but the hydraulic parts
must remain on the machine.
If converted to a vane tailboard only, upgrade the straw
chopper as follows:
1. Remove both covers (A) and (B).
ZX387490 —UN—21JAN20
IMPORTANT: To allow removal of the hydraulic
components without draining the hydraulic oil
reservoir, use the vacuum pump D15032NU.
