2.
At bottom of streetside platform steering cylinder (21), slowly loosen and then remove two pipe plugs (22).
3.
Allow fluid to drain from steering cylinder (21) onto mainbeam and into drain pan until most of fluid stops draining
from cylinder.
WARNING
Person operating steering valve at the hydraulic control module, must operate
steering valve so that enough pressure is applied to the cylinder to force fluid out
of the cylinder. Do not allow steerable axles to move or too much pressure will be
applied and serious injury to personnel may result.
Person watching fluid drain from cylinder must stand back away from platform,
keeping the cylinder in full sight, to avoid fluid from being sprayed onto them or
injury to personnel may result.
NOTE
In order to adequately perform the following steps, one person must operate
steering valve while another person checks fluid draining out of cylinder.
4.
Using one person stationed at hydraulic control module, slowly operate steering valve for a left turn (para. 2-6). Use
caution not to turn any of the steerable axles. If axles start to move, release steering valve handle; then, operate
handle again until axles do not move. Observe fluid draining out of cylinder (21).
5.
Continue to hold pressure on steering valve (para. 2-6) until a steady stream of hydraulic fluid flows out of cylinder
(21) for approximately 10 seconds. Then, release steering valve handle. Monitor hydraulic tank fluid indicator.
6.
Slowly operate steering valve for a right turn (para. 2-6) being careful not to turn any of the steerable axles. If axles
start to move, release steering valve handle. Then, operate handle again until axles do not move. Second person
must observe fluid draining out of cylinder (21).
7.
Continue to hold handle for steering valve (para. 2-6) until a steady stream of hydraulic fluid flows out of steering
cylinder (21) for approximately 10 seconds. Then, release handle of steering valve. Monitor hydraulic tank fluid
indicator.
8.
Allow all fluid inside steering cylinder (21) to drain into drain pan until fluid stops.
9.
Install two pipe plugs (22) into bottom of steering hydraulic cylinder (21).
