hitachi isuzu 4jj1

Here is the instruction show you guide on how to repair ISUZU 4JJ1 N-Series 3.0L engine intake air flow IAF valve control circuit open P02E0.

hitachi isuzu 4jj1

 

DESCRIPTION:

The ECM controls the intake air flow (IAF) valve opening based on the engine running condition and by controlling  the lAF valve motor. The lAF valve position is detected by the position sensor and relayed to the ECM.lf the ECM detects an open circuit on the motor circuits, the DTC will set.

CONDITION FOR RUNNING THE DTC:

1 The battery voltage is between 10 and 16 volts.

2 The desired lAF valve position is more than 18.5%.

 

CONDITION FOR SETTING DTC:

The ECM detects an open circuit on the lAF valve motor control circuit for 1 second.

 

ACTION TAKEN WHEN THE DTC SETS:

1 The ECM illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.2. 2 The ECM records the operating conditions at the time the diagnostic falls, The ECM stores this information in the Freeze Frame/ Falure Records

 

The ECM Apply Defaulted Warning Action And Fail-Safe Controls:1. MIL: ON

2 DPF Regeneration Control Inhibition

3 Cruise Control lnhibition

 

CONDITION FOR CLEARING THE DTC:

1 The ECM turns OFF the MIL after 3 consecutive driving cycles when the diagnostic runs and does not fail.

2 A current DTC clears when the diagnostic runs and passes.

3 A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported after the ECM turns OFF the Ml.

4 Use the diagnostic tool to clear the MIL and the DTC.

 

DIAGNOSTIC AIDS:

lf an intermittent condition is suspected, refer to the Intermittent Conditions.

Note: If more than one diagnostic test is available, the selected test will be highlighted.

 

Display Area

The Fuel Rail Solenoid Test display area has three columns:

Description – Lists the available fuel rail pump solenoid numbers

Mode – Displays the current mode of the cylinder; i.e., whether it is “Powered” or “Cutout”

Test Result – Displays “OK”, “Not OK (Short)”, or “Not OK (Open),” after the test has completed

 

Buttons

The Buttons available on the Fuel Rail Solenoid Test screen are:

Change – Click to change the state of the solenoid. Changing the state of the solenoid allows troubleshooting by “cutting out” and subsequently repowering an individual solenoid.

How to Inspect Rod and Cap for John Deere 9.0L Engine

This instruction show you guide on how to inspect rod and cap for John Deere 9.0L OEM engine.

John Deere Parts ADVISOR EPC 2025

 

 

Inspect Rod and Cap

1 Inspect rod and cap for wear or damage, such as chips or nicks in the joint areas.

IMPORTANT: Do not nick the joint surfaces of rod and cap. This is very critical on Precision Joint™

rods to assure proper seating. Never scrape joint surfaces (C) with a wire brush or other tool; the

interlocking mating surfaces must be preserved.

 

2 Inspect in and around cap screw holes (B) in cap. If any defects are found, replace rod and cap.

3 Carefully clamp rod in a soft-jawed vise (cap end upward).

 

4 Install cap WITHOUT bearing.

IMPORTANT: Never use new connecting rod cap screws when checking rod bore I.D. Use new cap screws only for final assembly of connecting rods.

 

5 On Precision Joint™ connecting rods: Initially tighten rod cap screw closest to piston end, then tighten other cap screw to the following specifications.

 

Specification

Precision Joint™

Connecting Rod Cap

Screw—Torque……………… 95 N·m (71 lb-ft) plus 90–100° turn clockwise

See TORQUE-TURN CONNECTING ROD CAP SCREWS, described later in this group.

1

 

6 Using an inside micrometer, measure rod bore atcenter of bore and record measurements as follows:

  • At right angle to rod/cap joint (A).
  • At 45° left of measurement step “A” (B).
  • At 45° right of measurement step “A” (C).

 

Specification

Connecting Rod Bore

(Without Bearings)—ID…………..87.487—87.513 mm (3.444—3.445 in.)

 

7 Compare the measurements. If difference between the greatest and least measurement is more than 0.04 mm (0.0016 in.), the rod and cap are out-of-round.

Replace both connecting rod and cap.

Specification

Connecting Rod

Bore—Maximum

Out-of-Round…………………………………………………0.025 mm (0.0010 in.)

 

8 Measure rod’s piston pin bore-to-crankshaft bore center-to-center dimension (A) and compare with specification given. If measurement is not within specification, replace rod.

Specification

Centerline of Piston

Pin Bore-to-Crankshaft

Bore—Dimension…………………..217.95—218.05 mm (8.581—8.585 in.)

JCB 3CX 4CX Boom Lock Cable Remove and Replacement Guide

This instruction show you guide on how to remove and replace boom lock cable for JCB 3CX 4CX backhoe loader.

 

 

The boom lock control A and associated cable is housed in the R.H. side console as shown.

Note the routing of the existing cable and route the new cable in the same way.

 

Preparations:
2025 JCB ServiceMaster 4 v25.1.0

2017 JCB Parts Plus+ and Repair Service Manual

JCB Electronic Service Tool

 

 

Removal

1 Park the machine on firm level ground, apply the parking brake. Lower the loader arms and excavator to the ground, switch OFF the engine and remove the starter key.

 

2 Working at the boom, remove the cable ball stud B from the boom lock casting.

3 Loosen the lock nut and disconnect the bulkhead fitting C from the bracket. Feed the end of the cable back underneath the cab to the rear wheel arch on the R.H. side of the machine and release the cable from the clamp assembly at position X as shown. Remove the spring clip D from the outer sleeve.

 

4 Working in the cab, unscrew the knob and lock nut from the boom lock control A. Remove the fixings from the side console panel and carefully lift up the rear corner of the side console panel over the boom lock control outer sleeve.

5 With the rear corner of the side console panel lifted up,carefully pull the boom lock cable up into the cab through the aperture in the cab floor.

 

Replacement

Replacement is the reverse of the removal sequence.

1 After fitting the cable, with the control knob pressed down adjust the bulkhead fitting C to take up any slack in the cable. The cable should be tight but must not lift the boom lock from its fully down position.

2 Operate the boom and check that the boom lock will engage and disengage correctly using the control knob in the cab. Check the boom stop setting, see Boom Stop Setting.
