cylinder base end into the barrel (see figure 9) . If plastic plug is installed in base end as shown
(see figure 9) it will allow the insertion of the base end into the barrel if plug is removed. Make certain
that the ports on the base end are aligned with thew cylinder head as shown (see figure 9 item 8
& 9) , the ports must be aligned this way.

nuts must be screwed on at the same rate and on each end, try to keep the same amount of threads
sticking out the nuts on both ends of the tie-rods. Snug the nuts down an all 4 tie rod evenly and
alternating as to keep the same amount of pressure evenly. Torque the tie-Rod nuts to
80 ft. lbs
(based on a 1/2” tie-rod).

12. Install the cylinder onto mower, Mount the cylinder with the base end (figure 9 item 8) to the
deck lug. Mount the cylinder head / rod end (figure 9 item 9) of the cylinder to the axle lug. When
first using the rebuilt and/or new cylinder it is not unusual for a light amount of oil to be pushed
out of the vent. The amount is the amount that was used to oil components during assembly.
If excessive amount leaks through the vent, cylinder is not functioning properly. Recheck the
assembly steps for possible assembly error.
