IMPORTANT: Spools and body are matched and
must be replaced as a unit. Spools
must be installed into the same
bores from which they were
removed for proper operation of
each function.
Always use new O-rings. Damaged
or used parts will leak.
NOTE: Note location and position of fittings and
linkages to aid in assembly.
Lubricate all O-rings with petroleum jelly
during assembly.
Inspect all parts for wear or damage. Replace as
necessary.
• Apply clean John Deere Low Viscosity HY-GARD ®
oil on all internal parts during assembly.
• Apply MPG-2 ® Multi-Purpose Polymer Grease on
springs (K, N and U) and inside of caps (Q and R).
• Tighten caps (Q and R) to 31 N·m (23 lb-ft).
