MAINTENANCE AND SERVICE9451 3-3-06-2GENERAL INFORMATIONRegular maintenance is the key to long equipment life and safe operation. Maintenancerequirements have been reduced to an absolute minimum. However, it is very important thatthese maintenance functions be performed as described below.LUBRICATION Lubricate all grease fittings with a multi-purpose grease.DAILY Physically check all pins, bushings, cotter pins, nuts, etc., for signs of wear or loose fit. Tighten as required, replace where necessary.Clean equipment of all dirt, oil, and excess grease.Check for missing or illegible Safety / Warning Decals. Check all fittings and hydraulic hoses for leaks.WARNING! Escaping hydraulic / diesel fluid under pressure can penetrate the skincausing serious injury. Fluid escaping from a very small hole can be almostinvisible. Use a piece of cardboard or wood, rather than hands to search forsuspected leaks.Keep unprotected body parts, such as face, eyes, and arms as far away aspossible from a suspected leak. Flesh injected with hydraulic fluid may develop gangrene or other permanent disabilities. If injured by injected fluid,see a doctor at once.Stop the engine and relieve pressure before connecting or disconnectinglines.Tighten all connections before starting engine or pressurizing lines.CARDBOARDHYDRAULIC HOSEOR FITTINGMAGNIFYINGGLASS22 75584MAINTENANCE AND SERVICE10516 3-3-06WARNING!

Looseblades hinder the spades ability to cut the roots. As the blades and plastic wear plates begin to wear,the blades may need to be adjusted to maintain the close positioning of the blades and prevent gapping between the blades. There are shims provided between the tower and the blades and the towerand the tower cover that can be removed (to tighten the tower on the mainframe) or moved to theopposite side (to maintain blade tightness).To adjust blades:1. Loosen the .50" capscrews securing thetower cover and blades to the tower.2. Slideinashimorremoveashimasrequiredto maintain blade tightness.
(NOTE: Keep all shims for future adjustments.)
3. Re-tighten capscrews and check the blade
positioning.
NOTE: Once the blades can no longer be
adjusted the wear plate(s) will need to be replaced.

WEAR PLATE REPLACEMENT
If the wear plate(s) have worn to the point that the towers are riding on the capscrews or when
the blades have reached the end of their adjustment and gapping between the blades is still evident
the wear plate(s) will need to be replaced.
To replace wear plates:
1. Remove the blade and the tower cover from the tower.
2. Position a wrench on the flat spot of the blade cylinder to prevent it from rotating as you remove
the lock nut securing the blade to the tower.
3. Remove the tower and inspect the wear plates.
Replace any wear plates that are worn. NOTE:
There are two different style wear plates on
each slide tower. The front wear plate is a
harder plastic than the remaining three.
4. Drill out the rivets to remove the wear plate. Install
new wear plate with new rivets (#10104) into the
existing holes and secure by driving the center
pin with a hammer.
5. Re-install the tower and secure the blade cylinder
to the tower using the hardware removed in step
#2.
6. Install the tower cover to the tower while inserting
all of the original shims.
7. Install the blade to the tower while inserting all of
the original shims.
8. Check blade position. Insert or remove shims as
required to obtain blade tightness.

CYLINDER SEAL REPLACEMENT
The following information is provided to assist you in the event you should need to repair or rebuild a hydraulic cylinder. When working on hydraulic cylinders, make sure that the work area and tools are clean and free
of dirt to prevent contamination of the hydraulic system and damage to the hydraulic cylinders. Always protect the
active part of the cylinder rod (the chrome section). Nicks or scratches on the surface of the rod could result in
cylinder failure. Clean all parts thoroughly with a cleaning solvent before reassembly.
DISASSEMBLY PROCEDURE
IMPORTANT: Do not contact the active surface of the cylinder rod with the vise. Damage to the rod could
result.
THREADED TYPE GLAND
1. Rotate the gland with a spanner wrench counterclockwise until the gland is free of the cylinder tube.
2. Pull the cylinder rod from the cylinder tube and inspect the piston and the bore of the cylinder tube for
deep scratches or galling. If damaged, the piston AND the cylinder tube must be replaced.
3. Remove the hex nut, piston, flat washer or spacer tube (if so equipped), and gland from the cylinder rod. If
the cylinder rod is rusty, scratched, or bent, it must be replaced.
4. Remove and discard all the old seals.
ASSEMBLY PROCEDURE
IMPORTANT: Replace all seals even if they do not appear to be damaged. Failure to replace all seals may
result in premature cylinder failure. NOTE: Seal kits will service most cylinders of similar bore size and
rod diameter.
1. Install the cylinder rod seal in the gland first. Be careful not to damage the seal in the process, as it is
somewhat difficult to install.
NOTE: A special installation tool (Part #65349) is available to help with installing the seal. Simply fit the end of the
tool over the seal so that the large prong of the tool is on the outside of the seal, and the two smaller prongs on the
inside. The lip of the seal should be facing towards the tool. Rotate the handles on the tool around to wrap the seal
around the end of the tool.

Now insert the seal into the gland from the inner end. Position the seal in
its groove, and release and remove the tool. Press the seal into its seat
the rest of the way by hand.
2. Install the new piston ring, rod wiper, O-rings and backup washers, if applicable, on the piston.
Be careful not to damage the seals. Caution must be used when installing
the piston ring. The ring must be stretched carefully over the piston with
a smooth, round, pointed tool.
3. After installing the rod seal inside the gland, as shown in step #1, install
the external seal.
NOTE: Threaded glands may have been equipped with a separate O-ring and
backup washer system or a polypak (all in one) type seal. Current seal kits contain a polypak (all in one) type seal to replace the discarded seal types on ALL
THREADED GLANDS.
4. Slide the gland onto the cylinder rod, being careful not to damage the rod
wiper. Then install the spacer, or flat washer (if so equipped), small o-ring,
piston, and hex nut onto the end of the cylinder rod.
5. Secure the cylinder rod (mounting end) in a vise with a support at its center.
Torque the nut to the amount shown for the thread diameter of the cylinder
rod (see chart).

IMPORTANT: Do not contact the active surface of the cylinder rod with the
vise. Damage to the rod could result.
6. Apply a lubricant (such as Lubriplate #105) to the piston and teflon ring. Insert the cylinder rod assembly
into the cylinder tube.
IMPORTANT: Ensure that the piston ring fits squarely into the cylinder tube and piston groove, otherwise
the ring may be damaged and a leak will occur.
7. Use a spanner wrench to rotate the gland clockwise into the cylinder. Continue to rotate the gland with the
spanner wrench until it is
