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).
