Step 3. Check control valve for hydraulic oil leakage.

a. If hydraulic oil leakage is observed at control valve, remove and repair it (para 3-30a).

b. If hydraulic oil leakage is not observed at control valve, proceed to step 4.

Step 4. Crack (loosen) fittings shown at side. Start

engine and operate at idle speed, Place SHIFT

control lever in LEFT position and check if

hydraulic oil flows from fittings; place SHIFT

control lever in RIGHT position and check if

hydraulic oil flows from fittings.

a. If hydraulic oil does not flow from

fittings, replace control valve (para

b. If hydraulic oil flows from fittings,

remove and repair sideshift cylinder

assembly (para 3-30c) (tighten fittings).

NOTE

After completion of each check, turn engine off.

Step 1. Check pressure relief valve setting (para 2-48b(2), steps 20 through 22).

a. If pressure relief valve setting is not correct, adjust for proper setting (para 2-48b(2), step 23).

b. If pressure relief valve setting is okay, proceed to step 2.
