EXCERPT:

50 Disassembly and assembly - Cab and its attachments
• Adjust opening and closing of front window assembly (1) according to the following
procedure.
1. Open and close front window assembly (1) to check that it does not interfere with the rails and that the rollers are not caught.
2. If there is any problem in opening or closing of front window assembly (1), loosen mounting bolts (16) of roller adjustment bracket (15) and adjust the condition of the front window, and then tighten the mounting bolts again.
- Make sure that bracket (15) is not slanted when mounted.
* Mounting bolt (16) of bracket (15): 19.6 to 25.0 Nm {2.0 to 2.5 kgm}
3. Pull up front window assembly (1) to the ceiling and lock it.
- Make sure that the assembly is certainly locked.
4. Install right corner bracket (4).
- Tighten lightly for the meantime. Bolts are tightened to the specified torque after
adjusting the locks for the front window assembly (1) in its "closed" position in the following step 6.
- Install right corner bracket (4) so that clearance (a) between rail (17) and right corner bracket (4) becomes 0 to 2.0 mm.
- There must be no level difference on rolling surface (R) for the roller.
5. Install left corner bracket (3).
- Tighten lightly for the meantime. Bolts are tightened to the specified torque after
adjusting the locks for the front window assembly (1) in its "closed" position in the following step 6.
- Install left corner bracket (3) so that clearance (b) between rail (18) and left corner bracket (3) becomes 0 to 2.0 mm.
- There must be no level difference on rolling surface (R) for the roller (same as the right corner bracket).
6. Adjust the locks for the front window assembly
(1) in its "closed" position according to the following procedure.
1) Install right and left corner brackets (4) and (3) in roughly right positions so that front window glass (19) is closely attached to cab-side trim seal (20).
2) Check the working condition of right and left locks (22) and (21) when opening and closing front window assembly (1).

STRUCTURE AND FUNCTION - HYDRAULIC PUMP
FUNCTION
1. LS VALVE
• The LS valve detects the load and controls the discharge amount.
This valve controls main pump discharge amount a according to differential pressure PLS (=PP- PLS) (the difference between main pump pressure PP and control valve outlet port pressure PLS) (called the LS differential pressure).
• Main pump pressure PP, pressure PLS (called the LS pressure) coming from the control valve output, and pressure PSIG (called the LS selection pressure) from the proportional solenoid valve enter this valve. The relationship between discharge amount a and differential pressure PLS, (the difference between main pump pressure PP and LS pressure PLS) (=PP- PLS) changes as shown in the diagram on the right according to LS selector pressure PSIG.
• When PSIG changes between 0 and 2.94 MPa (0 and 30 kg/cm2), the spool load changes according to this, and the selector point for the pump discharge amount changes at the rated central value between 0.64 and 2.45 MPa (6.5 and 25 kg/cm2).
2. TVCVALVE
• When the pump discharge pressure PP (self-pressure) is high, the TVC valve controls the pump so that no more oil than the constant flow (in accordance with the discharge pressure) flows even if the stroke of the control valve becomes larger. In this way it carries out equal horsepower control so that the horsepower absorbed by the pump does not exceed the engine horsepower.
• In other words, if the load during the operation becomes larger and the pump discharge pressure rises, it reduces the discharge amount from the pump; and if the pump discharge pressure drops, it increases the discharge amount from the pump. The relationship between the average of the front and rear pump discharge pressures (PP1 + PP2)/2 and pump discharge amount a is shown on the right, with the current given to the TVC valve solenoid shown as a parameter.
However, in the heavy-duty operation mode, there are cases where it is given the function of sensing the actual speed of the engine, and if the speed drops because of an increase in the load, it reduces the pump discharge amount to allow the speed to recover. In other words, when the load increases and the engine drops below the set value, the command to the TVC valve solenoid from the controller increases according to the drop in the engine speed to reduce the pump swash plate angle.
