Vacuum Pump Inspection

S6JB0A1436076

Install a vacuum gauge to the vacuum circuit using 3-
way joint (1) as shown in the figure and measure
vacuum.
If vacuum is out of specification, check vacuum leakage,
if OK than replace vacuum pump.

Vacuum pump specification
–75 kPa (–10.9 psi) or more (keep for 20 seconds at
engine speed 1,500 r/min first)
–85 kPa (–12.3 psi) or more (keep for 20 seconds at
engine speed 3,000 r/min first)

Timing Belt and Belt Tensioner Removal and
Installation

S6JB0A1436051

CAUTION

!

• Never turn injection pump pulley

counterclockwise. It may cause damage of
injection pump.

• After timing belt is removed, never turn

crankshaft and camshafts independently. If
turned, interference may occur between
piston and valves and valves themselves,
and parts related to piston and valves may
be damaged.

• Do not bend or twist timing belt.
• Do not allow timing belt to come into

contact with oil, water, etc. It may be
adversely affect belt life.

• When replacing a timing belt, be sure to

replace timing belt pulley and crankshaft
pulley bolt.

Removal

1) Remove accessory drive belt referring to “Accessory

Drive Belt and Idler Pulley Removal and Installation:
For Diesel Engine Model in Section 1J”.

2) Remove timing belt cover No.1 (1) and timing belt

cover No.2 (2).

3) Turn crankshaft pulley clockwise, and stop turning

crankshaft pulley immediately before mark (2) of
camshaft pulley (3) matches with mark (1) of belt
inner cover.

4) Remove TDC pin cap, and insert special tool (A) into

TDC pin hole as shown in figure.

Special tool
(A): 09912–46510

5) Turn crankshaft pulley clockwise until crankshaft

touches special tool (A).
