Removal
A raised and badly supported machine can fall on you
causing severe injury or death. Position the machine on a
firm, level surface before raising one end. Ensure that the
other end is securely chocked. Do not rely solely on the
machine hydraulics or outriggers to support the machine
when working under it.
Disconnect the battery cables while you are under the
machine, to prevent the engine from being started.
1. Raise and support the machine to gain access to the

steering cylinder.

2. With the engine not running, turn the steering wheel in
both directions to release any pressure in the hydraulic
lines to the steering cylinder.
3. Be prepared to collect the oil as you remove the steering
lines. Slowly loosen the hydraulic hoses to release any
remaining pressure. Install a plug in the hose end and a
cap on the cylinder port. Place a tag on the hoses for
identification and correct assembly.
4. Remove locking bolts A Figure 10-31 and pivot pins B
from both ends of the steering cylinder.
5. Remove the steering cylinder from the axle.
