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.

• Clean threads in end of spools, detent (Q) and
screws (J) using Clean and Cure Primer. Apply
thread lock and sealer (medium strength) on threads
of detent (Q) and screws (J).

Multi-Purpose Polymer Grease on

springs (H and S) and inside of caps (K and P).
