Front Cutting Deck Lift Cylinder Removal
Front Cutting Deck Lift Cylinder Installation
Hydraulic System: Service and Repairs
Make sure that cutting decks are fully lowered before loosening
hydraulic lines from a lift cylinder. If cutting decks are not fully
lowered as hydraulic lines are loosened, a cutting deck may drop
unexpectedly.
Note: To ease assembly, label all hydraulic hoses to identify their correct
position on the lift cylinder.
4. Disconnect hydraulic hoses from lift cylinder fittings. Put caps or plugs on
fittings and hoses to prevent contamination. Tag hydraulic lines for proper
assembly.
5. Remove flange head screw and flange nut that secure the pin to the lift arm.
Remove pin from lift arm and cylinder shaft clevis which will free lift cylinder
from lift arm.
6. Remove cotter pin and two (2) flat washers from one end of the clevis pin.
Pull clevis pin from frame and cylinder barrel clevis. Discard cotter pin.
7. Remove lift cylinder from machine. Record lift cylinder location as right and
left cylinders are different.
8. If hydraulic fittings are to be removed from lift cylinder, mark fitting orientation
to allow correct assembly. Remove fittings from cylinder and discard O−rings.
1. If fittings were removed from lift cylinder, lubricate and place new O−rings
onto fittings. Install fittings into cylinder ports using marks made during the
removal process to properly orientate fittings. Tighten fittings (see
the Hydraulic Fittings (SAE Straight Thread O-Ring Fittings) (page
2. Make sure that cotter pin and two (2) flat washers are installed on one end
of clevis pin.
3. Position cylinder barrel clevis to frame and insert clevis pin into frame and
cylinder clevis. Secure lift pin with two (2) flat washers and a new cotter pin.
4. Insert pin through lift arm and cylinder shaft clevis. Secure pin to lift arm with
flange head screw and flange nut.
5. Remove caps or plugs placed during removal to prevent contamination.
6. Using tags placed during cylinder removal, correctly attach hydraulic hoses
to lift cylinder (see
(page 5–7)).
7. Lubricate lift cylinder grease fittings.
8. After assembly is completed, operate lift cylinder from stop to stop to
verify that hydraulic hoses and fittings are not contacted by any machine
components.
9. Check hydraulic system for leaks before returning the machine to service.
10. Fill reservoir with new hydraulic fluid as required (see Operator's manual).
