Kubota Loader LA340

Re-tightening of hardware of the loader

After 20 hours to 30 hours of initial loader operation, re-tighten all mounting bolts and nuts to the required torque value as follows.

Main frame M14 bolts or nuts 147 N⋅m (15.0 kgf⋅m) [108 lbf⋅ft]

NOTE: Before finally tightening all mounting hardware of the loader, start the engine and apply down pressure to the bucket until the loader raises the front wheels slightly.

Can you rotate the mounting pins easily?

Did you tighten all bolts and nuts?

!WARNING: To avoid personal injury or death, never operate the front loader with a loose main frame. Any time bolts and nuts are loosened, retighten to specified torque. Check all bolts and nuts frequently and keep them tight. Check the bolts and nuts of the main frame regularly especially when they are new.

Are all bolts and nuts of the main frame tight?

Enter the torque of bolt and nut of the main frame (1) in N⋅m

Enter the torque of bolt and nut of the main frame (2) in N⋅m

Did you lubricate all grease fittings?

Did you lubricate the joints of the control-lever-linkage?

Did you check the hydraulic-fluid-level of the tractor?

Is the hydraulic-fluid-level low?

If the hydraulic-fluid-level is low, add the hydraulic fluid as described in the tractor operator's manual.

Did you change the filter element and the hydraulic fluid as recommended in the tractor operator's manual?

CAUTION: Be sure to check and service the tractor on a flat surface with the bucket on the ground, engine shut off, the starter key removed, and the parking brake on.

WARNING: When removing the engine-side-covers, be careful not to touch hot loader cylinders. Allow all surfaces to cool before performing maintenance.

Before servicing the loader or the tractor, be sure to place the boom of the loader in contact with the ground. When raising the boom of the loader during service or maintenance, support the boom as shown in the figure.

Check all hardware of the loader daily before operation. Tighten the hardware of the loader to torque values as specified in the GENERAL TORQUE SPECIFICATION on page 144.

With the engine off and the bucket on the ground, inspect all hoses for cuts or wear. Check for signs of leaks and make sure all fittings are tight.

WARNING: Escaping the hydraulic fluid under pressure can obtain sufficient force to penetrate skin, causing serious personal injury. Before disconnecting lines, be sure to relieve all pressure.

Before applying pressure to the loader system, be sure that all connections are tight and that lines, tubes, and hoses are not damaged.

Fluid escaping from a very small hole can be almost invisible. Use a piece of cardboard or wood, rather than your hands, to search for suspected leaks.

If you are injured by escaping fluid, see a doctor at once. Serious infection or allergic reaction will develop if proper medical treatment is not administered immediately.
