REMOVAL:

Some hoses may contain small amounts of trapped hydraulic pressure. Wear protective clothing including

a face shield, head gear and gloves. Fine streams of hydraulic fluid under pressure cannot be readily

seen but can easily penetrate the skin causing severe personal injury. Use extreme caution and be alert

whenever breaking into a hydraulic system.

Hydraulic fluid may be extremely hot. Allow the SPEMS to stand fifteen minutes before breaking into

hydraulic system.

NOTE

Disconnect hydraulic hoses as required.

(1) Remove four socket head cap screws (1, Figure 3-41) that are inset in the hydraulic manifold block (2).

Remove preformed packing (3) and discard.

NOTE

Lay the hydraulic manifold block down and out of the way. Be careful not to damage the hydraulic hoses.

(2) Place a drip pan under the hydraulic pump. Use two wrenches to disconnect the hydraulic discharge hose

from outlet port (4) at the swivel connection.

(3) Remove the two hydraulic pump retaining capscrews (5).

(4) Remove the hydraulic pump (6) from the transmission. Remove preformed packing (7) and discard.

Take steps to ensure no dust or debris gets into the transmission or hydraulic manifold block.

(5) Remove elbow fitting (8) from body.
