5. Remove the cylinder Base end cap (figure 2 Item 8) . To remove the cylinder base end cap use
a small brass (soft metal hammer) tap the base end cap until it slide out of the cylinder barrel (figure
2 item 5) . The base end of the cylinder will now be open (See figure 3).
6. Remove the cylinder head (figure 3 item 9) . Pull the cylinder rod out from inside barrel approx
2 inches by pulling on the cylinder rod clevis (figure 3 item 3). Using a brass (soft metal) hammer
tap the barrel side of the cylinder head (figure 3 item 9) . Cylinder head will slide out of barrel, when
the shoulder of the cylinder head comes out of the barrel, pull the cylinder clevis (figure 3 item 3) .
The cylinder rod clevis, cylinder rod, cylinder head, piston and piston nut will all pull out as an
assembly when pulled from the barrel
(see figure 4) .
7. Remove the plastic plug (figure 3 item 13) from the cylinder head. With cylinder head, piston,
cylinder rod and cylinder rod clevis assembly removed from the barrel, the barrel can be removed
from the vise, the drain pans can be set aside
(see figure 3).
8. Clamp the cylinder rod, cylinder head and piston assembly into the vise (see figure 4). When
clamping the cylinder rod clevis into the vise make certain to clamp it as shown (figure 4). the clevis
must be clamped as shown or the clevis could be damaged by bending the ears of the clevis.
9. Slide a block of wood (figure 4 wood support block) between cylinder rod and work bench, insert
a material between block (figure 4 soft non-scratching material) and the cylinder rod, this will protect
the cylinder rod from damage. Use a strap wrench to hold the cylinder rod (figure 4 strap wrench)
to hold the cylinder rod from turning while screwing the piston nut (figure 4 piston nut) off the piston
nut is RH Thread locknut.

3. Place drain pans under cylinder to catch hydraulic oil that may still be in cylinder ( figure 2 Drain
Pans) . Using ratchet w/ sockets or boxed end wrenches (repair technicians choice) remove the
tie-rod hex nuts (figure 2 item 7). The tie-rods have a hex nut on each end (figure 2 item 7) , not
all the hex nuts will screw off on the same side. The hex nut with the least amount of resistance
is going to screw off. This is OK as the tie-rods can be pulled out from either direction.
4. When a hex nut has been removed from each tie-rod (it will not matter which end of tie-rod)
pull the tie rods out from the cylinder base and cylinder head (figure 2 item 6). There are a total
of 4 tie-rods that will need to be removed (see figure 3) . .
