LCRV (LOAD CONSCIOUS
REDUCING VALVE)

LCRV consists of sensing part and hydraulic control
part.

1. Sensing Part

It detects the changes of vehicle height caused
by vehicle load. It consists of load sensing spring
and control lever which change according to
vehicle load.

2. Hydraulic Control Part

It consists of valve stem devices which controls
hydraulic pressure according to load detected by
sensing part.

4. Place alignment marks between the lock nut (b)

and adjusting screw (c) after the valve setting.

5. LCRV setting should be performed with unloaded

vehicle condition.

Setting Method

1. Install the connecting rod (a) to the No.1 hole.

2. Adjust the clearance “X” to be 0mm and tighten

the bolt (c) using the lock nut (b).

Installation Notice

Tightening Torque

14 - 18 N•m

 (10 - 13 lb-ft)

3. Remove the connecting rod (a) from the No.1 hole

and reinstall it to the No.2 hole.

Notice:

•

Fluid leaking from LCRV results from poor valve
open/close or sealing wear caused by the foreign
materials in the LCRV.

•

When you change or repair the LCRV, it may affect
the braking performance. Thus, ensure to use the
approved part.
